New York state snow emergency: five dead, 100+ trapped in monster winter storm

NBC News: Troopers in all-terrain vehicles set out Wednesday to reach drivers trapped in a ferocious winter storm that dumped 5 feet of snow outside Buffalo, New York — with plenty more on the way. More than 130 miles of Interstate 90, the main artery running east and west across New York state, remained closed, with no word when it would reopen. More than 100 cars were reported trapped on Tuesday night.

Authorities in Erie County, which includes Buffalo, reported a fifth death, a 46-year-old man found in a car. Four were reported Tuesday, one in a car crash and three from heart attacks, including two people who were shoveling snow.

The towns south of Buffalo were believed to be the hardest hit, but snow totals were hard to come by. The National Weather Service said some places could approach the record for a single-day snowfall in the United States, 6 feet 4 inches.

...Gov. Andrew Cuomo declared a state of emergency for 10 counties, and the National Guard was activated to help clean up. The state deployed 526 snowplows and 17 large snow blowers. The weather service warned that 3 to 8 more inches of snow could fall Wednesday, and up to 2 feet more by Thursday night outside Buffalo....

EU court rules UK government must clean up dangerous air pollution

John Vidal in the Guardian (UK): The government will be forced to urgently clean up illegal air pollution in British cities following a ruling on Wednesday in the European court of justice. It is likely to see many diesel cars and heavy goods vehicles restricted from city centres within a few years.

The landmark case, brought by a small environmental group through the UK courts, will allow people to sue the government for breaching EU pollution laws and will force ministers to prepare plans for many cities to improve air quality.

The court firmly rejected Britain’s long-standing approach to complying with EU air pollution laws which has been to appeal to Europe for time extensions. The government has admitted that under current plans, several cities in the UK will not meet its legal limits for the toxic nitrogen dioxide gas (NO2) until after 2030. This is 20 years after the original deadline set by Europe.

Instead, UK courts will now be able to order the government to produce a plan which achieves NO2 limits in a period of time as “short as possible”. The UK Supreme court is expected to interpret what the time frame should be next year.

“Thousands of people die because of air pollution in Britain every year. This ruling will save lives by forcing the government to finally take this issue seriously. They will now have to come up with an urgent plan to rid our towns and cities of cancer-causing diesel fumes,” said Alan Andrews, lawyer with Client Earth which brought the case.

“This sets a groundbreaking legal precedent in EU law and paves the way for a series of legal challenges across Europe,” he said....

Study counters case for climate change-violence link

Lou Del Bello in SciDev.net: Climate change is far from being solely to blame for violence in Sub-Saharan Africa, say researchers — other factors matter much more. Their paper, published on 10 November in the journal Proceedings of the National Academy of Sciences, contradicts earlier studies that found that higher temperatures are a major risk factor in conflict.

For instance, last year a different group concluded that a shift towards hotter conditions by a single statistical unit known as a ‘standard deviation’ — equivalent to, for example, warming an African country by 0.4 degrees Celsius for a year — caused a four per cent rise in the likelihood of personal violence and a 14 per cent increase in conflict between groups.

But now a team led by John O’Loughlin, a geographer at the University of Colorado Boulder in the United States, says that previous research may have overlooked other key triggers such as political instability, poverty and geographical conditions.

O’Loughlin’s team examined these factors alongside exceptionally hot or dry periods in Sub-Saharan Africa to assess the chances of increased violence. Breaking the area down into subregional grids, the researchers pinpointed 78,000 ‘conflict events’ from the past 33 years and matched them with weather conditions and social and geographical factors.

They found that conflicts such as riots, protests or violence against civilians were more common when temperatures were particularly high. But they also discovered an inconsistent relationship between temperature deviations on the one hand and different types of conflict and different subregions on the other.

And, more critically, they found that longer periods of higher temperatures and wet or dry conditions had less impact on conflict than other influences, such as recent nearby violence and a lack of democracy, says O’Loughlin....

Questions over Mali's ebola response

IRIN: The failure of a top Malian hospital to detect probable cases of Ebola has raised questions about whether the country's health system is sufficiently prepared to tackle the disease.

"We have several confirmed cases," Samba Sow, head of the Mali's National Centre for Disease Control (CNAM), told IRIN. "Our goal is to prevent the virus from spreading." But the government only released an Ebola emergency plan on 30 October, a week after the first Ebola case.

In Kayes, where a two-year-old girl tested positive for Ebola on 23 October, the hospital was caught off-guard. Only two of its 160 workers had received training on how to detect and treat Ebola patients and how to protect themselves while doing so, said hospital director Toumani Konaré. "The staff had the right protective gear, but they didn't know how to use it," he told IRIN.

Before the current outbreak in Mali, the World Health Organization (WHO) had categorized the country as at-risk, due to its long border and strong economic ties with Guinea, where the epidemic began. It was targeted as a country to receive technical assistance, including training on infection prevention, epidemiological surveillance and contact tracing.

Sow said preparations started in April. However, those preparations were focused mostly on the 805km border that Mali shares with Guinea. The government started to send a few health workers to check travellers for fever and other signs of the virus among the chaos of trucks, buses, bush taxis and motorbikes at border checkpoints.

The Ministry of Health says the Kouremalé border checkpoint, where an imam who died of Ebola in Mali on 27 October had entered from Guinea, checks more than 1,000 people and 150 vehicles per day....

Italy faces billion euro bill for killer rainfall

Terra Daily via AFP: Torrential rain drenched northern Italy again Monday as the damage suffered by just one of the regions hit by floods and landslides was put at one billion euros ($1.25 billion).

In Sesto Calende, a small town near Lake Maggiore and the Swiss border, the central square resembled a giant pond, a handful of sandbags doing a poor job of preventing the water from soaking the ground floors of houses and businesses. "It is a nationwide problem caused by decades of neglect and poor governance," said one resident, Mauro, with a resigned shrug.

A total of 12 people have died in weather-related accidents in northern Italy since mid-October. Three deaths at the weekend included a pensioner and his granddaughter who were buried alive when a landslide hit their house on the shores of Maggiore in the early hours of Sunday morning, the third tragedy of its type in less than a week.

Claudio Burlando, the president of the Liguria region, which includes the entire Italian Riviera, said the damage incurred on his patch alone in the last month now exceeded one billion euros.

Apart from the clean-up costs, millions of euros worth of crops have been destroyed and many fields rendered unsuitable for grazing or planting, while motorways and other infrastructure, including a Genoa cemetery where zinc coffins were washed away at the weekend, will have to be repaired at public expense.

Most costly of all, the water-management systems which have proved incapable of dealing with exceptional conditions will have to be upgraded....

Corps of Engineers embraces uncertainty of climate change

A press release from the US Army Corps of Engineers: The U.S. Army Corps of Engineers is adapting the way it operates to accommodate climate changes that could cause floods and droughts. "During the past 50 years, much of the U.S. has seen an increase in periods of high temperature and severe floods and heavy downpours and droughts," said Lt. Gen. Thomas Bostick, commanding general, U.S. Army Corps of Engineers. "We all have observed changes to the frequency and the severity of these events."

In April and May of 2011, he said, residents in the Mississippi basin experienced some of the worst flooding seen since 1927. The next year, in 2012, droughts in the same region impacted navigation along the same river, which required "a significant response effort" to get traffic moving again on the river.

"That is what the nation, and the world, is experiencing," Bostick said. "These changes are increasing the risk and the vulnerability of operations, missions and infrastructure; effective climate change preparation and resilience are important to the corps. Adaptation and preparation is not an optional thing for the Corps of Engineers. It's something we feel we have to do."

During a press conference Thursday, at the Corps of Engineers headquarters here, Bostick explained that the corps is aware of climate change, and is changing the way it operates to accommodate changes due to climate.

"We're translating science into policy, we are adapting new infrastructure to withstand changes in climate, and we are looking at our existing infrastructure to see where it is vulnerable to changing climate and the steps we must take to make it more resilient," Bostick said. "We are also looking at how all of this fits into a systems approach."...

Netherlands bans poultry transport after discovering bird flu

Seed Daily via AFP: Dutch officials on Sunday banned the transport of poultry in the Netherlands after the discovery of a highly infectious strain of bird flu which could jump to humans.

The "highly pathogenic" form of avian influenza discovered at a farm in the centre of the country is very dangerous to birds and "contamination can occur from animals to humans," the Dutch government said in a statement. About 150,000 chickens at the farm in Hekendorp are to be destroyed by Dutch health authorities, which for the moment have not identified the exact strain of flu.

Avian influenza is fatal for chickens, and poses a health threat to humans, who can become sickened by handling infected poultry. The H5N1 strain of bird flu has killed more than 40
0 people, mainly in Southeast Asia, since first appearing in 2003. Another strain of bird flu, H7N9, has claimed more than 170 lives since emerging in 2013.

The Dutch transport ban is to last a maximum of 72 hours and includes moving poultry, eggs and bird manure....

Mudslides kill four along Swiss-Italian border

Yahoo News via AFP: At least four people were killed as landslides triggered by torrential rain slammed into houses and buildings on either side of the Swiss Italian border Sunday, police and media said. In the rain-drenched southern Ticino region of Switzerland, two people died and four were injured when a mudslide slammed into a small residential building, regional police said.

On the other side of the border, a pensioner and his granddaughter were killed when another landslide engulfed a house on the Italian shores of Lake Maggiore, local media reported. Three other family members survived.

Those landslides were the latest of many to recently have hit northern Italy and southern Switzerland amid incessant rainfall over recent weeks. They also came a day after storms in southern France killed six people, including a mother and her two small sons whose car was swept away in flooding.

In Switzerland, the bodies of two local women, aged 34 and 38, were pulled Sunday from the rubble of the three-story apartment building in Davesco-Soragno, near Lugano, after being hit by the mudslide shortly before 2:30 am (0130 GMT), Ticino police said.

Another resident had returned home after the landslide hit and was unharmed, but police said they were still searching the area to make sure no one else was under the rubble. The tragedy came 10 days after a young mother and her three-year-old daughter were killed when a landslide swept away their house in the same region...

Groundwater warming up in synch

Peter Ruegg at ETH in Zurich: Global warming stops at nothing – not even the groundwater, as a new study by researchers from ETH Zurich and KIT reveals: the groundwater’s temperature profiles echo those of the atmosphere, albeit damped and delayed.

For their study, the researchers were able to fall back on uninterrupted long-term temperature measurements of groundwater flows around the cities of Cologne and Karlsruhe, where the operators of the local waterworks have been measuring the temperature of the groundwater, which is largely uninfluenced by humans, for forty years. This is unique and a rare commodity for the researchers. “For us, the data was a godsend,” stresses Peter Bayer, a senior assistant at ETH Zurich’s Geological Institute. Even with some intensive research, they would not have been able to find a comparable series of measurements. Evidently, it is less interesting or too costly for waterworks to measure groundwater temperatures systematically for a lengthy period of time. “Or the data isn’t digitalised and only archived on paper,” suspects the hydrogeologist.

Based on the readings, the researchers were able to demonstrate that the groundwater is not just warming up; the warming stages observed in the atmosphere are also echoed. “Global warming is reflected directly in the groundwater, albeit damped and with a certain time lag,” says Bayer, summarising the main results that the project has yielded. The researchers published their study in the journal Hydrology and Earth System Sciences.

The data also reveals that the groundwater close to the surface down to a depth of around sixty metres has warmed up statistically significantly in the course of global warming over the last forty years. This water heating follows the warming pattern of the local and regional climate, which in turn mirrors that of global warming.

The groundwater reveals how the atmosphere has made several temperature leaps at irregular intervals. These “regime shifts” can also be observed in the global climate, as the researchers write in their study. Bayer was surprised at how quickly the groundwater responded to climate change....

Will geoengineering make people give up cutting their carbon footprint?

Adam Corner in the Guardian (UK): If you thought there was a machine that could magically remove carbon dioxide from the atmosphere and bury it underground, would you be less likely to worry about reducing your own carbon footprint?

The question is not entirely hypothetical. Geoengineering is the catch-all term for a suite of technologies that could one day be used to alter the Earth’s climate and combat global warming. Most of them are unlikely to ever see the light of day: they are considered too risky, too unpredictable, or too reckless to be taken seriously by the scientific community.

...As geoengineering has gradually moved on to the policy agenda, debates about the ethics of meddling with the global thermostat have become more prominent. Central among these is whether geoengineering might undermine fragile public and political support for the more pressing business of reducing carbon emissions.

This is what is known by economists and philosophers as a ‘moral hazard’ argument: the phenomenon whereby people who feel insured against a particular risk are more likely to exhibit risky behaviour. Will the prospect of geoengineering make people feel ‘insured’ against the risks of climate change, and indulge in ‘riskier’ environmental behaviour themselves?

In a paper published in the Philosophical Transactions of the Royal Society on Monday, my colleague Nick Pidgeon and I attempted to answer that question. Using a nationally representative online survey, we provided 610 people with a ‘factsheet’ about geoengineering, and then asked them a series of questions. One striking finding was that some people seem more susceptible to the ‘trap’ of the moral hazard than others.

People who were wealthier, and who identified with self-focused values such as power and status, were more likely to agree with the statement “Knowing geoengineering is a possibility makes me feel less inclined to make changes in my own behaviour to tackle climate change.”...

Prepare for more lightning

Will Dunham in Reuters: Rising global temperatures may cause a big jolt in the number of lightning strikes in the United States over the rest of the 21st century in the latest example of extreme weather spawned by climate change, scientists say.

Researchers forecast on Thursday that lightning strikes will increase by about 50 percent by 2100 in the continental United States because thunderstorms will become more explosive in the coming decades thanks to a warming planet.

This increase could lead to more wildfires because lightning already triggers half of these blazes in the United States, the researchers said. Lightning also kills dozens of Americans annually, with that risk expected to rise.

Considering factors including precipitation levels, cloud buoyancy and warming air, the scientists predicted a 7 percent increase in the number of lightning strikes with each degree Fahrenheit global average temperature increase (12 percent for each degree Celsius).

The 11 different climate models used in the study pointed to an increase of 7 degrees Fahrenheit (4 degrees Celsius) between now and 2100. "There are about 30 million strikes per year in the contiguous U.S. now. So, in 2100, we would expect about 45 million per year," said climate scientist David Romps of the University of California, Berkeley and the U.S. government's Lawrence Berkeley National Laboratory, who led the study published in the journal Science....

Farmers and scientists divided over climate change

A press release from Purdue University: Crop producers and scientists hold deeply different views on climate change and its possible causes, a study by Purdue and Iowa State universities shows. Associate professor of natural resource social science Linda Prokopy and fellow researchers surveyed 6,795 people in the agricultural sector in 2011-2012 to determine their beliefs about climate change and whether variation in the climate is triggered by human activities, natural causes or an equal combination of both.

More than 90 percent of the scientists and climatologists surveyed said they believed climate change was occurring, with more than 50 percent attributing climate change primarily to human activities. In contrast, 66 percent of corn producers surveyed said they believed climate change was occurring, with 8 percent pinpointing human activities as the main cause. A quarter of producers said they believed climate change was caused mostly by natural shifts in the environment, and 31 percent said there was not enough evidence to determine whether climate change was happening or not.

The survey results highlight the division between scientists and farmers over climate change and the challenges in communicating climate data and trends in non-polarizing ways, Prokopy said. "Whenever climate change gets introduced, the conversation tends to turn political," she said. "Scientists and climatologists are saying climate change is happening, and agricultural commodity groups and farmers are saying they don't believe that. Our research suggests that this disparity in beliefs may cause agricultural stakeholders to respond to climate information very differently."

...Focusing on the causes of climate change, however, is likely to polarize the agricultural community and lead to inaction, said study co-author Lois Wright Morton, professor of sociology at Iowa State University. To foster productive dialogue, she said, scientists and climatologists need to "start from the farmer's perspective."...

Ocean primed for more El Nino

Space Daily via SPX: The ocean is warming steadily and setting up the conditions for stronger El Nino weather events, a new study has shown. A team of US, Australian, and Canadian researchers sampled corals from a remote island in Kiribati to build a 60-year record of ocean surface temperature and salinity. "The trend is unmistakeable, the ocean's primed for more El Nino events," says lead-author Dr Jessica Carilli, now based at the University of Massachusetts, Boston.

Team member Dr Helen McGregor from the Research School of Earth Sciences at The Australian National University said the change in El Nino patterns could have a major impact on Australia's weather. "During an El Nino event warm waters to the north of Australia move eastward, taking their rainfall with them," she said. "This changes the pattern of Australia's rainfall and droughts significantly."

El Ninos occurs irregularly every two to seven years and have often coincided with severe droughts in Queensland and New South Wales. The current conditions show that a weak El Nin
o has brought warmer and drier conditions to Australia for late 2014.

The team focused on regional differences in sea temperatures that generate the circulating winds known as the Walker Circulation, which drive the trade winds that bring moisture across the Pacific Ocean to the north of Australia.

The island from which the corals were sampled, Butaritari, was chosen for its location at one end of the Walker Circulation....

Micro loans can offset effects of climate change

The Daily Star (Bangladesh): Microfinance institutions should modify their financial products for those at vulnerable climate zones to deal with global warming, a keynote speaker at a climate change seminar said yesterday.

The MFIs offer three types of products: loans, savings and insurance. Each product can be modified depending on the type of shock the MFI customers might be suffering from, said Fazle Rabbi Sadeque Ahmed, coordinator of Palli Karma-Sahayak Foundation's Community Climate Change Project.

For instance, in areas that are becoming more prone to flooding, MFIs can encourage: aquaculture initiatives among farmers, floating gardens, investment on raised tube wells for safe water and new houses to be built on raised beds or raised embankments.

All these measures can be supported by making use of loans, savings and insurance products that include a set of climate sensitive conditions, he said.

Ahmed's comments came at the inaugural session of a daylong seminar styled 'climate change adaptation at community level: the role of MFIs', jointly organised by the Institute of Microfinance and Bangladesh Water Partnership. The event was aimed at identifying the bankable projects and overcoming the challenges at village level in implementing climate change resilience through microcredit....

Ebola a stark reminder of link between health of humans, animals, environment

Emily Caldwell at the Ohio State University News Room: For many, global public health seems like an abstract and distant problem – until the Ebola virus is diagnosed among people in our midst. Though no one would call the Ebola pandemic a good thing, it has presented an opportunity for scientists to alert the public about the dire need to halt the spread of infectious diseases, especially in developing and densely populated areas of the world.

“What often seems like an abstract notion becomes very concrete when a deadly virus previously contained in Western Africa infects people on American soil,” said Wondwossen Gebreyes, professor of veterinary preventive medicine at The Ohio State University. “It does create a certain sense of urgency and awareness that this world is much smaller than we think.”

Gebreyes is the lead author of an article published in the Nov. 13, 2014, issue of PLOS Neglected Tropical Diseases that makes the case for accelerating efforts to put “One Health” into action. One Health refers to a strategy to more fully understand and address the links between animal health, human health and the environment.

The paper emphasizes the danger of zoonotic infections – those transmitted from animals to humans – and the staggering damage they do, especially in developing nations that lack a variety of resources. These diseases don’t just kill people, but they cause tremendous economic harm in a variety of ways: killing livestock, reducing the ranks of qualified health and education providers, creating political unrest and stopping development in its tracks.

There is an urgent need for progress. Approximately 75 percent of emerging infectious diseases are those transmitted from animals to humans, and the world is on pace to experience at least one deadly disease outbreak each year.

...“To attain a true One Health approach, we need broad recognition of the interconnectivity among the health of humans, domestic or wild animals and the environment, which are all closely linked by the pathogens that they share,” he said....

Ground water depletion driving global conflicts

Chris Arsenault at the Thomson Reuters Foundation: Global ground water supplies, crucial for sustaining agriculture, are being depleted at an alarming rate with dangerous security implications, a leading scientist said.

"It's a major cause for concern because most of the places where it (ground water depletion) is happening are major food producing regions," James Famiglietti, a University of California professor who conducts research for the National Aeronautics and Space Administration (NASA), said in an interview with the Thomson Reuters Foundation. "India is the worst off, followed by the Middle East, and the U.S. is probably number three ... the Chinese, particularly on the north China plain, are more water limited than people believe."

Famiglietti's conclusions are based on his latest research paper "The global ground water crisis" published in the journal Nature Climate Change last month. The study uses analysis of satellite images to warn that ground water in many of the world's largest aquifers is being exploited at a far faster rate than it can be naturally replenished.

Farming accounts for more than 80 percent of the United States' water use, according to the U.S. Department of Agriculture, and the figures are similar globally. Famiglietti has been called to the Pentagon a number of times to discuss the potential impact of groundwater scarcity with leading military planners....

Wildfire suppression a losing battle

Tim Radford in the Standard-Examiner via Climate News Network: A research report says towns, rural settlements and even whole societies will become increasingly vulnerable to catastrophic losses unless people learn to live with wildfire, rather than try to fight it.

But Max Moritz, of the College of Natural Resources at the University of California, Berkeley, and research colleagues from the United States and Australia report in Nature journal that they also found evidence from three continents suggesting that government policies can make things worse.

Fire-fighting strategies and land-use practices actually encourage development on inherently hazardous landscapes, and so risk making losses more calamitous in the decades to come as climate change and population increase exacerbate the hazard.

The researchers considered the Mediterranean basin of Europe, the southwestern U.S., and Australia — three regions in which wildfires play a part in the natural management of the ecosystems, and therefore all naturally at risk, and all home to communities badly hit by wildfires in recent years.

The research paper concludes: “The ‘command and control’ approach typically used in fire management neglects the fundamental role that fire regimes have in sustaining biodiversity and key ecosystem services. Unless people view and plan for fire as an inevitable and natural process, it will continue to have serious consequences for both social and ecological systems.”

Researchers develop new model to study epidemics

A press release from New York University: For decades, scientists have been perfecting models of how contagions spread, but newly published research takes the first steps into building a model that includes the loop linking individual human behavior and the behavior of the epidemic itself.

The first results of the highly complex modeling led by researchers at the New York University Polytechnic School of Engineering were recently spotlighted as “brilliant research” by the American Physical Society.

Eventually, the team hopes the model will more accurately predict who should be vaccinated and isolated first and what travel restrictions will be most effective in preventing different epidemics. The speed of mass communication and modern travel requires changes to most current models. Even underdeveloped countries now have electronic devices that quickly spread the word about diseases and airplanes can carry the infected everywhere nearly as quickly, explained Alessandro Rizzo, visiting professor of mechanical engineering and a leader of the research effort. Modeling thus must be improved by accounting for contagions that spread mor
e slowly than travelers and ones that spread more quickly.

The new model also takes into consideration the differing rates at which the infected and those who merely fear infection react and thereby spread disease. For example, prior work by other researchers indicates that symptomatic people will often self-isolate and—not surprisingly—that the actions of the infected are more relevant to the spread of an epidemic than those of healthy individuals who are avoiding a contagious area. But in some kinds of epidemics, ill people who are asymptomatic behave as if they are healthy, selfishly infecting others. The new model seeks to account for these individual reactions and more.  The research team expects that a fully tested and working model is several years away...

Dengue's spread flies under the radar amid ebola scare

AFP: One of the most familiar sounds in Malaysia's capital is the approaching drone of a fumigation fogger spewing thick white plumes of insecticide, part of so-far futile efforts to arrest a spiralling dengue fever outbreak.

Malaysia is among several countries across Asia and Latin America grappling with a mosquito-borne virus that is proving tough to eradicate as it infects millions.

While the Ebola threat has captured headlines, the World Health Organization (WHO) warns that dengue -- while far less lethal -- has become one of the fastest-growing global health threats, contracted by 50-100 million people each year.

"The increase in dengue incidence and severity of the outbreaks is a global phenomenon, with a 30-fold increase over the past five decades," said Ahmed Jamsheed Mohamed, a doctor in the WHO's Southeast Asia office, adding that eradication is "not seen as feasible in the near future".

...While Ebola has killed nearly 5,000 people this year, mainly in west Africa, with an estimated 13,000 infections, dengue kills up to 20,000 annually, and 40 percent of the world's population live in dengue-risk areas....

Florida water demand shrinks even as state, US grow

Andy Reid and Kevin Spear in the Sun-Sentinel (Florida): Aross the country and in Florida, Americans are only using as much water as almost 45 years ago, even though the population has grown by more than 100 million people, the U.S. Geological Survey reported this week. Environmentalists point to efficient toilets, low-flow showers and limits on lawn sprinkling, saying water conservation is the way to go.

"We have hardly scratched the surface of what can be achieved by really effective efforts toward water conservation," Audubon Florida's Charles Lee said in a comment on facebook.com/envirospear.

In Florida, increased water demand has been anticipated for years but has failed in nearly spectacular fashion to materialize. Earlier this year, a USGS report for Florida stated that freshwater use in the state decreased 22 percent from 2000 to 2010, while the state's population increased 18 percent. In South Florida, the amount of water used is about the same as it was in 1995, even with 1.1 million more people in the region, according to the South Florida Water Management District.

As a result, per capita water use in Broward, Palm Beach and Miami-Dade counties also dropped about 22 percent from 1995 to 2010, according to the district. In 1995, the average person in southeast Florida used 184 gallons of water per day. That dropped to 142 gallons per day by 2010.

Conservation efforts take much of the credit, district officials said. "Our freshwater is a limited resource," said Mark Elsner, the district's water supply administrator. "The conservation initiative is hitting. … We are definitely more efficient than we were 20 years ago."...

Analysing heat waves – new index allows predicting their magnitude

A press release from the Joint Research Centre: JRC scientists have developed a new index to measure the magnitude of heat waves, in cooperation with colleagues from five research organisations. According to the index projections, under the worst climate scenario of temperature rise nearing 4.8⁰C, extreme heat waves will become the norm by the end of the century. Heat waves like the one that hit Russia in summer 2010, the strongest on record in recent decades, will occur as often as every two years in southern Europe, North and South America, Africa and Indonesia.

The Heat Wave Magnitude Index is the first to allow comparing heat waves over space and time. It takes into account both the duration and intensity of heat waves and can serve as a benchmark for evaluating the impacts of future climate change. Results also show that the percentage of global area affected by heat waves has increased in recent decades, and the probability of occurrence of extreme and very extreme heat waves is projected to increase further in the coming years.

The index is based on an analysis of daily maximum temperatures, which was carried out to classify the strongest heat waves that occurred worldwide during three study periods (1980-1990, 1991-2001 and 2002-2012). In addition, a combination of models is used to project the future occurrence and severity of heat waves, under different scenarios as established in the latest Assessment Report of the Intergovernmental Panel on Climate Change (IPCC).

Taking into account the disastrous effects of the 2003 and 2010 heat wave events in Europe, and those of 2011 and 2012 in the USA, results show that we may be facing a serious risk of adverse impacts over larger and densely populated areas if mitigation strategies for reducing global warming are not implemented...

The ‘Yolanda’ tragedy

Babe Romualdez in the Philippine Star: It’s been a year after that fateful day on November 8, 2013 – but to this day, no one can say for certain how many people perished in the aftermath of Typhoon Yolanda [also known as Haiyan]
.  Estimates on the number of casualties are as high as 7,000 with some 1,800 missing or presumed dead – which is not too far from the projection made by police chief superintendent Elmer Soria who was eventually sacked as Eastern Visayas regional head for saying the number of fatalities could reach 10,000.

No one could have predicted the kind of devastation that Yolanda would bring, with the super typhoon now having gained infamy as the strongest ever to hit not only the Philippines but the world – whose power was described by meteorologists as “off the charts,” and that its intensity could not be tracked or handled by widely used satellite intensity scales because it has approached the “theoretical maximum intensity for any storm, anywhere.”

As some experts have noted, no amount of preparation could have spared Eastern Visayas from the intensity of the super typhoon. This was particularly true with Tacloban City that was the hardest hit because its location put it in the middle of two bodies of water that hit it with towering waves as high as five meters brought about by the storm surge – the first one coming from the direction of the Pacific Ocean through Tacloban Bay, then the second one from Cancabato Bay.

Storms, typhoons, earthquakes and other natural calamities do not choose – they can hit any country regardless of economic stature, they do not distinguish  “names” nor political affiliation, neither religion nor social status. Devastating as they are, tragedies such as that wrought by super typhoon Yolanda can also bring out the best in people, seen in the way Filipinos banded together as they gave donations, volunteered time and effort to repack relief items and offered prayers for casualties as well as survivors. The response from the international community was – for lack of a better word – overwhelming, with help still pouring in until this very day to speed up the rehabilitation of the areas that were damaged....

Vietnam eyes water-saving technology for its rice farms

Fatima Arkin in SciDev.net: Agriculture experts say application of alternate wetting and drying (AWD) technology in Vietnam’s rice farms, one of South-East Asia’s largest rice-producing countries, holds great promise in cutting water use and greenhouse gas emissions from rice cultivation without sacrificing yield output.

Vietnam along with Bangladesh and Colombia recently partnered with the Climate and Clean Air Coalition (CCAC) to introduce the large-scale application of AWD, also known as controlled irrigation in which farmers periodically drain rice paddies rather than keeping them perpetually flooded. The number of non-flooded days can range from 1 to 10 day
s. The technology can reduce water use by 25 per cent and estimated to cut methane from flooded rice field by 50 per cent.

But getting farmers to adopt it will be a struggle, Nguyen Hong Son, vice-president of the Vietnam Academy of Agricultural Sciences, tells SciDev.Net during an interview at the Fourth International Rice Congress in Bangkok, Thailand (27 October to 1 November).

...Aside from economic savings through lower water consumption and pumping costs, there is also evidence that AWD can help crops perform better and improve soil conditions so that machines can operate more efficiently in the fields, says Björn Ole Sander, who is coordinating the effort.

But AWD is not without controversy. Adopting the irrigation method will increase nitrous oxide emissions, which Sander himself acknowledges will be anywhere from 20 to 100 per cent. Still, given that paddy rice does not produce much nitrous oxide to begin with, the decrease in methane, which the crop produces in heaps, will more than offset any increase in nitrous oxide, says Sander. “We still have a huge overall reduction in greenhouse gas emissions,” he adds...

Solving the poo problem in South Africa

Miriam Mannak in AllAfrica.com: Access to toilets for Cape Town's growing urban poor is a regular flash-point, featuring angry demonstrations and hurled allegations by competing political factions. The city - and the Western Cape province in which it is located - are governed by members of the Democratic Alliance. Most of the South Africa's people live in areas governed by the ruling African National Congress, which won over 60 percent of the votes in recent national elections.

But whoever is in charge, South Africa shares a practical and political headache with urban areas around the world: providing sanitation to an influx of people, primarily from poor rural communities. "On current evidence," writes Richard Palmer in a blog post carried on the Future Cape Town website,  "it seems the truth of the matter is that providing basic sanitation services to South Africa's poor seems too big a challenge for our major cities, regardless of who governs them."

A report by the South African Human Rights Commission (SAHRC), published in March, doesn't leave much to the imagination. According to researchers, members of 1.4 million South African households don't have access to sanitation and are therefore forced to relieve themselves in the open. The bulk of them live in rural areas of KwaZulu-Natal, North West and the Eastern Cape.

Additionally, 26 percent of all South African households, 3.8 million in total, only have access to below-standard sanitation infrastructure. These facilities have crumbled and deteriorated to such extent that they can be considered unfit to be used....

Future air quality could put plants and people at risk

EurekAlert via Sheffield University: By combining projections of climate change, emissions reductions and changes in land use across the USA, an international research team estimate that by 2050, cumulative exposure to ozone during the summer will be high enough to damage vegetation. Although the research findings - published in Atmospheric Chemistry and Physics Discussions - focus on the impact in the USA, they raise wider concerns for global air quality, according to lead researcher Dr Maria Val Martin, from the University of Sheffield's Faculty of Engineering

"Modelling future air quality is very complex, because so many factors need to be taken into account at both a global and local scale," says Dr Val Martin. "The picture isn't uniform across the USA, with some areas seeing much higher surface ozone levels than others. However, our findings show that the emissions reductions we're expecting to achieve won't guarantee air quality on their own, as they will be offset by changes in climate and land use and by an increase in wildfires. This is an issue that will affect all parts of the world, not just the USA."

...The model showed that, if greenhouse gas emissions peak in 2040, then by 2050 surface ozone will remain below levels set to safeguard human health, despite increases in ozone caused by higher temperatures and changes in agriculture and forestation. If emissions continue to rise until 2100, then some areas of the USA will see surface ozone above the safe levels set for human health.

However, when the researchers looked at the cumulative impact of ozone over three months in the summer - a standard growing season - they found that under both scenarios, the surface ozone levels would be high enough to cause damage to plants. This was particularly because during the summer, there were higher emissions from transport and industry of nitrogen oxides, which react with sunlight to create ozone.

...Co-researcher Professor Colette Heald, from Massachusetts Institute of Technology, adds: "Poor air quality is not just an issue in cities. Air pollution in pristine regions such as National Parks degrades visibility and can damage ecosystem health. Protecting natural ecosystems - and our enjoyment of them - will require us to consider and manage the impacts of emissions and climate change on future air quality."

Denying problems when we don’t like the solutions

A press release from Duke University: There may be a scientific answer for why conservatives and liberals disagree so vehemently over the existence of issues like climate change and specific types of crime. A new study from Duke University finds that people will evaluate scientific evidence based on whether they view its policy implications as politically desirable. If they don't, then they tend to deny the problem even exists.

“Logically, the proposed solution to a problem, such as an increase in government regulation or an extension of the free market, should not influence one’s belief in the problem. However, we find it does,” said co-author Troy Campbell, a Ph.D. candidate at Duke's Fuqua School of Business. “The cure can be more immediately threatening than the problem.”

...The researchers conducted three experiments (with samples ranging from 120 to 188 participants) on three different issues -- climate change, air pollution that harms lungs, and crime. “The goal was to test, in a scientifically controlled manner, the question: Does the desirability of a solution affect beliefs in the existence of the associated problem? In other words, does what we call 'solution aversion' exist?" Campbell said. "We found the answer is yes. And we found it occurs in response to some of the most common solutions for popularly discussed problems."

For climate change, the researchers conducted an experiment to examine why more Republicans than Democrats seem to deny its existence, despite strong scientific evidence that supports it. One explanation, they found, may have more to do with conservatives' general opposition to the most popular solution -- increasing government regulation -- than with any difference in fear of the climate change problem itself, as some have proposed.

Participants in the experiment, including both self-identified Republicans and Democrats, read a statement asserting that global temperatures will rise 3.2 degrees in the 21st century. They were then asked to evaluate a proposed policy solution to address the warming. When the policy solution emphasized a tax on carbon emissions or some other form of government regulation, which is generally opposed by Republican ideology, only 22 percent of Republicans said they believed the temperatures would rise at least as much as indicated by the scientific statement they read. But when the proposed policy solution emphasized the free market, such as with innovative green technology, 55 percent of Republicans agreed with the scientific statement.

...."Recognizing this effect is helpful because it allows researchers to predict not just what problems people will deny, but who will likely deny each problem,” said co-author Aaron Kay, an associate professor at Fuqua. “The more threatening a solution is to a person, the more likely that person is to deny the problem.”...

Aid agencies adapt to Ebola challenge

IRIN: From using Bitcoins to fundraise, to adopting new strategies to prevent malaria victims appearing to be Ebola cases, to working with new partners - aid agencies in West Africa are learning to adapt fast. "The response to every humanitarian crisis has to be context specific," said Nigel Clarke, the director of programme development and quality for Save the Children's operations in Liberia. "That's the key standard that humanitarian agencies utilize in all crises. But this Ebola crisis is unprecedented because of all the associated risks of cross infection."

Humanitarian workers, for example, would normally want to bring people together during times of crises, to do things such as spread key messages, distribute food and other supplies, and sit down with communities in groups to discuss needs, Clarke said.  "But a lot of those things are not possible in this context and so we are having to sort of adapt as we go."

In order to help get the outbreak under control, they have now branched out and partnered with the governments of Sierra Leone, Cuba and the UK, as well as other health agencies and workers, to establish and run a treatment centre in Freetown's Kerry Town.  The new, 100-bed Ebola Treatment Unit is the first time that Save the Children has ever worked on a global health emergency in this capacity.

"We're all in a place now where we never thought we would be," said Rob MacGillivray, Save the Children's country manager in Sierra Leone. "In the past, we never considered direct case management, but eventually the outbreak overtook us and now we've had to fight this battle in a way we've never fought a humanitarian battle in the past."....

Getting more out of Nature: genetic toolkit finds new maximum for crop yields

A press release from Cold Spring Harbor Laboratory: Scientists at Cold Spring Harbor Laboratory (CSHL) today announced a new way to dramatically increase crop yields by improving upon Mother Nature’s offerings. A team led by Associate Professor Zachary Lippman, in collaboration with Israeli colleagues, has discovered a set of gene variations that can boost fruit production in the tomato plant by as much as 100%.

Plant breeders will be able to combine different gene variants among the set to create an optimal plant architecture for particular varieties and growing conditions. The set of mutations will enable farmers to maximize yield in tomatoes and potentially many other flowering plants, including staple crops like soybeans.

“Traditionally, plant breeders have relied on natural variation in plant genes to increase yield, but yield gains are plateauing,” Lippman notes. “There is an immediate need to find new ways for plant breeders to produce more food.” Worldwide more than 842 million people do not receive adequate nourishment, about 1 person in 8 alive today. The cost of food is expected to increase and hunger is likely to become more widespread as the global population expands to beyond 9 billion by 2050.

...In a study published today in Nature Genetics, Lippman’s team identifies an array of new gene mutations that allow, for the first time, a way to fine-tune the balance of florigen to anti-florigen. This maximizes fruit production without compromising the energy from leaves needed to support those fruits. “We mixed and matched all of the mutations,” explains Lippman. “And we were able to produce plants with a broad range of architectures. Together, our collection of mutations forms a powerful toolkit for breeders to pinpoint a new optimum in flowering and architecture that can achieve previously unattainable yield gains.”

The breakthrough benefit of the toolkit, says Lippman, is that it allows farmers to customize genetic variations for particular varieties and growing conditions. “For example, we found that different combinations boost yields for cherry tomatoes and other fresh-market tomatoes compared to tomatoes that are processed for sauce, ketchup, and other canned products.  We’ve tested this in multiple genetic backgrounds, in multiple years, and in multiple environments – and the toolkit always provides a new maximum yield.”...

Fundamental change needed to save biodiversity

A press release from the Wildlife Conservation Society: When properly supported, protected areas are an invaluable tool in safeguarding biodiversity, says Dr. James Watson, Director of the Wildlife Conservation Society's Climate Change Program. But, he says with a group of colleagues in an article published Nov. 5 in Nature, only one in four is well managed. A fundamental change, they say, involving an increase in funding and a renewed political commitment is urgently needed to ensure that protected areas meet their full potential.

In advance of the paper's publication, Dr. Watson answered a few questions on the subject: What are the top three to five points you want people to take away from this Nature paper?

Protected areas (PAs), when well financed, and well resourced, work. Have a look at protected areas that save tigers, that save elephants, that sustain coral reef fisheries. They work becauce they stop destructive activities – plain and simple.

However, not all of them work. Only 20 percent of PAs are well managed which means 80 percent of PAs are not getting the funding they need. There is also clear evidence showing many nations around the world are backtracking their commitments towards PAs, leading to their delisting, degazetting and downsizing. These are not just in a few corrupt developing countries but the whole shabam – first world nations are leading the way in this poor behavior.

We need to recognize this backtrack. Tomeet the CBD commitments that nations have committed to, we need a step-change in terms of government commitment and funding. Money is important – and at about 70 billion dollars – doing the right thing is quite cheap (especially when one considers what we spend on the military). But is not simply about money … it’s about planning effectively. As the world’s population expands, as every nation on earth puts in place their economic development pathways, we need to actively and urgently identify those great landscapes and seascapes that are still functional, that still contain all of their species, and by their own nature make them resilient to climate change. We then need to actively seek their protection. We need to recognize that what we protect in the next 20 years counts the most because in 2030 there will be limited options for future appointments for PAs. The time to act is now....

Adaptation, mitigation activities can control climate change – IPCC report

EcoSeed: Climate change irreversible impacts to increase, however, there are options to adapt to climate change and stringent mitigation activities to manage it, finds new Intergovernmental Panel on Climate Change report.

The Synthesis Report, which sums and integrates the findings of the I.P.C.C. Fifth Assessment Report produced by 800 scientists..., is the most comprehensive assessment of climate change.

“Our assessment finds that the atmosphere and oceans have warmed, the amount of snow and ice has diminished, sea level has risen and the concentration of carbon dioxide has increased to a level unprecedented in at least the last 800,000 years,” said Thomas Stocker, co-chair of I.P.C.C. Working Group I.

The document reports with great certainty than in previous assessment the fact that emissions of greenhouse gases and other man-made drivers have been the dominant cause of observed warming since the mid-20th century.

According to the report, the more human activity disrupts the climate, the greater the risks. Continued GHG emissions will further warm and create long-lasting changes in all components of the climate system, increasing the likelihood of widespread and profound impacts affecting all levels of society.

“Adaptation can play a key role in decreasing these risks. Adaptation is so important because it can be integrated with the pursuit of development, and can help prepare for the risks to which we are already committed by past emissions and existing infrastructure,” said Vicente Barros, co-chair of I.P.C.C. Working Group II.

But adaptation alone is not enough. Substantial and sustained reductions of GHG emissions are at the core of limiting the risks of climate change, as it will not only reduce the rate and magnitude of warming, but also increase the time available for adaptation....

Study reveals startling decline in European birds

Terra Daily via SPX: Bird populations across Europe have experienced sharp declines over the past 30 years, with the majority of losses from the most common species, say the University of Exeter, the RSPB and the Pan-European Common Bird Monitoring Scheme (PECBMS) in a new study. However numbers of some less common birds have risen.

The study, published in the journal Ecology Letters, reveals a decrease of 421 million individual birds over 30 years. Around 90 percent of these losses were from the 36 most common and widespread species, including house sparrows, skylarks, grey partridges and starlings, highlighting the need for greater efforts to halt the continent-wide declines of our most familiar countryside birds.

Richard Inger from the University of Exeter said: "It is very worrying that the most common species of bird are declining rapidly because it is this group of birds that people benefit from the most."

"It is becoming increasingly clear that interaction with the natural world and wildlife is central to human wellbeing and significant loss of common birds could be quite detrimental to human society."

Birds provide multiple benefits to society. They help to control agricultural pests, are important dispersers of seeds, and scavenging species play a key role in the removal of carcasses from the environment. In addition, for many people birds are the primary way in which they interact with wildlife, through listening to bird song, enjoying the sight of birds in their local environment, feeding garden birds and through the hobby of bird watching....

Does it help conservation to put a price on nature?

A press release from the University of Cambridge: Putting a price on the services which a particular ecosystem provides may encourage the adoption of greener policies, but it may come at the price of biodiversity conservation. Writing today (30 October) in the journal Science, Professor Bill Adams of the University’s Department of Geography argues that assigning a quantitative value to nature does not automatically lead to the conservation of biodiversity, and may in fact contribute to species loss and conflict.

While assigning a monetary value to the benefits of an ecosystem can be an essential tool in the environmental planning process, unequal access to those benefits, particularly where there are differences in wealth and power, can lead to poor trade-offs being made, both for the ecosystem itself and those who rely on it.

“Putting a price on what nature provides is not in itself a conservation measure,” said Adams. “There is a risk that traditional conservation strategies oriented toward biodiversity may not be effective at protecting the economic benefits of an ecosystem, and vice-versa.”

…The ways in which we depend on our natural environment are increasingly expressed as ‘ecosystem services’, or the range of benefits we get from nature for free. These benefits include the provision of food and clean water, erosion control and carbon storage. Quantifying the value of nature in this way is meant to allow policymakers to consider the potential economic and social impacts of altering a particular habitat.

This approach does sometimes lead to win-win scenarios, where the value of ecosystem services is dependent upon a high level of biodiversity. One example is in the coffee plantations of Costa Rica, where the retention of forest habitat in areas around the plantations doubled the amount of pest control of coffee berry borer beetle provided by birds, which benefitted the coffee farmers while protecting biodiversity.

However, consideration of ecosystem services when making decisions does not automatically lead to retention of biodiversity. “In many cases, trade-offs are made,” said Adams….

Domestic climate change study paints bleak picture for Vietnam

Bao Cam in Thanh Nien News: Vietnam is suffering increasing damage from climate change, according to a recent report by a parliamentary committee. A report by the Committee of Science, Technology and Environment presented to the National Assembly, Vietnam’s legislature, showed that Vietnam is among the countries to be hit hardest by climate change in the coming years.

Natural disasters have cost the country around 1.5 percent of its annual gross domestic product (GDP) in the past two decades, the report said, citing findings of a study conducted by the committee. Typhoon Xangsane, for example, caused US$1.2 billion of damage in the central region in 2006.

Officials said Vietnam has yet to become a major greenhouse gas emitter, but its emissions continue to rise. “The threat of climate change has grown more vivid in Vietnam over the past 50 years,” the report said. “The average temperature increased by 0.5 degree Celsius, the sea rose more than 0.2 meters, natural disasters, floods and typhoons grew stronger and left many dykes became more vulnerable,” it said.

“Flooding caused by high tide has worsened in Ho Chi Minh City, Can Tho, and the Mekong Delta’s Ca Mau and Vinh Long provinces.” According to the report, areas suffering from the salinization of ground water and/or desertification have expanded due to rising temperatures....

Climate-driven migration increasing disease burden in Ethiopia

Thomson Reuters Foundation: ...Experts have linked more irregular rainfall and crop failures to a rise in migrant workers in Ethiopia. Meteorologists said Maksegnit, in the highlands, should record as much as 1,059 millimeters of rainfall during the peak season, but in the last few years rainfall has been as low as 317 millimeters.

That has led to a decline in staple crop farming, while cash crop farming in the lowlands pulls the struggling poor from the highlands, and toward new health threats.

Changing climatic conditions also are changing the range of the sandflies, said Daniel Argaw Dagne, of the leishmaniasis control programme at the World Health Organization. “Kalaazar is a vector borne disease that can be influenced by climate change,” he said. “Global warming affects the distribution and growth of vectors.”....

Nepal disaster preparedness needs to go local

IRIN: Mid-summer monsoon rains in Nepal triggered over three dozen floods and landslides, killing over 200 people and displacing tens of thousands. Experts say this highlights preparedness and response challenges and the urgent need for these to be prioritized in development plans and at local government level.

"There was nothing unpredictable about this summer's events in Nepal," Moira Reddick, coordinator at Nepal Risk Reduction Consortium (NRRC), a coalition of humanitarian, development, financial and government bodies, told IRIN.

"Until we see investments effectively risk managed and centred into development planning across all sectors of government and international community, we won't start to see the kind of revolution we need in terms of disaster management, risk-proofing and effective preparedness," she said.

Nepal's Ministry of Home Affairs put the number of people dead between June and September due to floods and landslides at 265, with 256 missing and 157 injured. A landslide on 2 August was the deadliest in the country's history. According to the International Federation of Red Cross and Red Crescent Societies (IFRC), monsoon disasters in 2014 affected over 200,000 people across Nepal and displaced more than 34,000.

Humanitarians point to a 2008 flood in the River Koshi, which killed several hundred and displaced nearly 60,000 families, as a turning point for Nepal's disaster mitigation and response work....

Italy ignores pleas, ends boat migrant rescue operation

Terra Daily via AFP: Italy on Friday ignored the pleas of aid agencies and confirmed the end of its search and rescue operation "Mare Nostrum", responsible for saving tens of thousands of boat migrants stranded in the Mediterranean.

"From tomorrow a new operation called 'Triton' begins," deputy prime minister and interior minister Angelino Alfano told journalists at a press conference, referring to a much more limited mission led by the EU border agency Frontex. "Mare Nostrum ends. Italy has done its duty,"

He said the government had spent some 114 million euros ($142 million) on the massive naval operation since two deadly shipwrecks in October last year left over 400 people dead.

The decision comes after growing criticism both within Italy and Europe that the rescue mission was creating an unintended "pull factor" for more migrants in makeshift boats to attempt the dangerous sea crossings.

Although the op -- which has saved over 150,000 people -- is being shelved, Italy said it will abide by the laws of the sea under which ships that spot migrants in trouble are obliged to rescue them....

Overcoming Ebola stigma takes time

IRIN: Ebola survivors in Liberia and Sierra Leone are facing mixed reactions as they return home after contracting the deadly virus. While some have been welcomed back into their communities, most are facing discrimination and stigmatization, or have even been shunned.

"I returned back to the community very happy," said Ibrahim Thomas, who lives in Freetown. "I didn't have any problems with the community or anybody. The worshippers at my mosque used to pray for me [when I was sick], so when I came back, they were so happy to see me alive and well."  Thomas, who lost his wife and two of his children to Ebola, said many of his neighbours have been sympathizing with him and doing what they can to help.

But not all survivors are so lucky. "I was devastated when I returned to my community," said 27-year-old Alhaji Bangura, who lost both parents, his wife and two children to Ebola in Sierra Leone. "I was very lucky to survive. but now some people are still afraid of me, even to come very close to me. I had so many friends before but now most of them have distanced themselves from me."  Bangura said most people will only talk to him outside their home and often refuse to give him any food or drink....
