Albay Gov. Joey Salceda told PIA News Service that the summit intends to to provide a venue for critical actors to agree that adaptation is a critical developmental concern that needs to be addressed to pursue and meet country's commitment towards Millennium Development Goals (MDGs) 2015.
Salceda furthered that local government units, as front liners in meeting the commitment towards achieving MDGs, must recognize that "development as usual" approach without considering climate variability and extremes, may pose as threat in meeting these development goals. "LGUs across the country must have a concerted effort to fast track achievement of MDGs, especially at the local level, to meet the 2015 target and share experiences in tracking their MDGs' progress," he said.
The governor, acclaimed "Senior Global Champion of Climate Change and Disaster Risk Reduction" by the United Nations (UN), also stressed that the powerful role of LGUs to trail blaze an aggressive and proactive climate and disaster resilient development plans/programs is enshrined in the Local Government Code of 1991.
The summit, according to Salceda, is designed to demonstrate and translate effective and efficient implementation of science-based analyses for climate change adaptation and disaster risk reduction measures and build consensus towards a way forward for climate change adaptation action….

Despite the seriousness of such changes to the ocean, however, the world has yet to deploy a complete suite of available tools to monitor rising acidification and other ocean conditions that have a fundamental impact on life throughout the planet.
Marine life patterns, water temperature, sea level, and polar ice cover join acidity and other variables in a list of ocean characteristics that can and should be tracked continuously through the expanded deployment of existing technologies in a permanent, integrated global monitoring system, scientists say.
The Partnership for Observation of the Global Oceans (POGO), representing 38 major oceanographic institutions from 21 countries and leading a global consortium called Oceans United, will urge government officials and ministers meeting in Beijing Nov. 3-5 to help complete an integrated global ocean observation system by target date 2015. It would be the marine component of a Global Earth Observation System of Systems under discussion in Beijing by some 71 member nations of the intergovernmental Group on Earth Observations.
The cost to create an adequate monitoring system has been estimated at $10 billion to $15 billion in assets, with $5 billion in annual operating costs. Some 600 scientists with expertise in all facets of the oceans developed an authoritative vision of characteristics to monitor at a 2009 conference on ocean observations….
But spokesman Andrew McGuinnes says the gains need to be kept in perspective. "Obviously we're glad that the dams have reached the 50 per cent milestone, it's been a long-time coming, but we do have to keep it in perspective," he said. "Five years ago, dams were at 60 per cent, 15 years ago, they were virtually full.
"So you could argue that the amount of drought and climate change that we've been through in the past 15 years really has changed our perception of how much 50 per cent represents." Mr McGuinnes says the dams are still prone to dry spells….

Last summer was Russia's hottest on record, with raging forest fires and droughts wiping out woodland and crops, forcing the bears to forage closer and closer to human settlements as the winter hibernation period approaches. A top-selling daily newspaper, Moskovsky Komsomolets, reported that one body was devoured in the village of Verkhnyaya Chova over the weekend. Two visitors to the cemetery shrieked at the shocking sight of the animal tearing into half-decomposed flesh, scaring the bear away, the paper reported.
Domestic pets, goats and cattle have all fallen prey to the bears since the summer, prompting unsightly fences to go up around farmland and more thoughtful disposal of garbage. And the signs are that locals are right to be more diligent: A man in his 20s barely escaped with his life when he was mauled by an aggressive bear in early September on the fringes of the regional capital city, Syktyvkar, the main local news channel reported….

With winter on the way, seven million people still do not have adequate shelter or quilts, blankets and warm clothing, according to the UN Office for the Coordination of Humanitarian Affairs (OCHA). The $2 billion appeal for aid for Pakistani flood victims, the largest-ever launched by the UN and its partners for a natural disaster, is currently 39 per cent funded.
OCHA spokesperson Elisabeth Byrs underscored the need for more contributions to the appeal, noting that some key sectors such as food security, health and camp coordination and management were “seriously underfunded.” Humanitarian assistance, notably in Sindh province, where 7.2 million people remained affected by the floods, was vital ahead of the winter, she told reporters in Geneva. The water has receded in some places, but it might take more than six months before other areas dried up.
She added that one million people are living in temporary shelters or in camps in Sindh, but the humanitarian aid pipeline is being restricted due to a lack of contributions, notably in the food sector. “The humanitarian response in Sindh must be stepped up,” she urged, while noting that this is very difficult to do given the lack of funding.
The UN High Commissioner for Refugees (UNHCR) believes tens and possibly hundreds of thousands of people will have to remain in camps throughout the winter, due to persistent standing waters in parts of Sindh and Balochistan….

"For example, improving coastal planning today could decrease the cost of a one-in-100-year storm surge in southeast Queensland in 2030 by $0.9 billion." The department also told the minister the private sector would have to bear a share of the costs of the effects of climate change. "It is neither affordable nor consistent with sound risk management for governments (commonwealth or state) to bear all the costs of adaptation." it says.
Most of the assets and activities at risk belonged to the states, local government or the private sector, but as climate change impacts increased, so would demands on the federal government to assist with the costs of adaptation….

Packing top sustained winds of 70 miles per hour, Tomas swept over the Caribbean's easternmost island of Barbados, blowing roofs off some houses, causing widespread power outages and blocking some roads with debris, residents said.
…At 8 a.m. EDT, Tomas was located about 70 miles southeast of St. Lucia, heading westwards, and it was expected to strengthen into a hurricane later on Saturday as it moved into the eastern Caribbean sea, the hurricane center said. Tomas is the 19th named storm of what has been a very active 2010 Atlantic Hurricane season….

The results-published this week in the journal Science-are likely to have "a small but significant impact on the predictions of computer models used to assess air quality, regulate emissions and estimate the health impact of air pollution," said Mitchio Okumura, professor of chemical physics at Caltech and one of the principal investigators on the research. "This work demonstrates how important accurate laboratory measurements are to our understanding of the atmosphere," said JPL senior research scientist Stanley P. Sander, who led the JPL team's effort. "This is the first time this crucial chemical reaction has been studied by two teams using complementary methods that allow its details to be understood."
The key reaction in question in this research is between nitrogen dioxide and the hydroxyl radical. In the presence of sunlight, these two compounds, along with volatile organic compounds, play important roles in the chemical reactions that form ozone, which at ground-level is an air pollutant harmful to plants and animals, including humans.
Until about the last decade, scientists thought these two compounds only combined to form nitric acid, a fairly stable molecule with a long atmospheric life that slows ozone formation.
Chemists suspected a second reaction might also occur, creating peroxynitrous acid, a less stable compound that falls apart quickly once created, releasing the hydroxyl radical and nitrogen dioxide to resume ozone creation.
But until now they weren't sure how quickly these reactions occur and how much nitric acid they create relative to peroxynitrous acid. The JPL team measured this rate using a high-accuracy, JPL-built, advanced chemical reactor. The Caltech team then determined the ratio of the rates of the two separate processes….

Risk perception researchers funded by the National Science Foundation (NSF) say some people will experience 'post-exposure letdown,' while others experience a 'post exposure wake-up call.' They say some people will not prepare for future fire events and some will not. Social scientists concede the finding is not surprising. They say the surprising thing is why - why do people who experience the same event perceive it differently and respond with contrasting tendencies?
An NSF-supported risk perception research team examined the phenomenon after a 2003 wildfire in Canada. Robin Gregory, senior researcher at the Decision Research office in British Columbia, Canada and Joseph Arvai, a professor of Judgment and Decision Making at Michigan State University, East Lansing, Mich. led the team.
They surveyed two sets of homeowners who survived a series of devastating wildfires in Kelowna, British Columbia. The fires caused the evacuation of more than 45,000 Kelowna residents, destroyed more than 300 homes and many businesses, and resulted in three deaths.
One group of surveyed homeowners from Kelowna did not lose their homes but were at risk of future wildfires because they lived in or near highly wooded areas similar to places where fires recently occurred. This group experienced what researchers call a post-exposure letdown.
These residents actually felt safer after the fires because they perceived themselves to have been the victims of an unfortunate low-probability event, and that the worst was over. As a result, people experiencing a letdown were unlikely to invest in costly and/or time-consuming measures to lower their future risks or to consider response strategies for future wildfires.
Contrasting sharply with the 'post-exposure letdown' was the feeling reported by the residents of Vernon, a community 32 miles north of Kelowna that was not affected by the fires but is situated in a similar urban-wildland interface area….

The report is entitled Water for Agriculture - Implications for future policy and practice and was commissioned by the Royal Agricultural Society of England (RASE). Conducted by scientists at the University of Reading, the study shows that climate extremes such as drought and flooding are likely to reduce the amount of water for agriculture and horticulture. This will provide a major challenge to farmers, researchers, plant breeders and policy makers across the UK.
According to the report, while climate change is expected to produce higher temperatures, drier summers and wetter winters across much of England, the effects on water availability will vary throughout the country and even, from year to year, in the same areas.
Direct abstractions are likely to become less reliable during the summer and more seasonal; meanwhile, the higher-intensity rainfall in certain periods of the year will produce high runoff, and thus less water will be able to percolate into aquifers, the report says.
Different crop types will be affected in different ways, requiring farmers to change their farming practices or even move their crops to other locations. Crops that need irrigation, such as vegetables and sugar beet in particular, may be forced to shift from the drier east of England to the wetter west of the country….

Two areas in Antarctica are of particular interest because of their potential sensitivity to global climate change: the Antarctic Peninsula, which is currently experiencing a warming exceeding the global mean and the disappearance of large ice shelf areas, and the Amundsen Sector of West Antarctica, where currently the largest flow rates and mass loss of the Antarctic Ice Sheet is occurring. For some glaciers the ice thickness is decreasing rapidly, and glaciers and ice streams are notably retreating back into the interior. With 0.3 millimeters per year, both regions are currently contributing considerably to the global sea level change of about three millimeters per year.
In the study, the mass balance of both regions is reevaluated from gravity data of the satellite mission GRACE. As a result, the estimates were lower than those of conventional mass balance methods. "With the GRACE time series, it was for the first time possible to observe how the large-scale ice mass varies in the two areas due to fluctuations in rainfall from year to year," said the GFZ scientists Ingo Sasgen. It has long been known that the Pacific El Niño climate phenomenon and the snowfall in Antarctica are linked. The complementary piece to the warm phase El Niño, the cold phase known as La Niña, also affects the Antarctic climate: "The cooler La Niña years lead to a strong low pressure area over the Amundsen Sea, which favors heavy rainfall along the Antarctic Peninsula - the ice mass is increasing there. In contrast, the Amundsen area is dominated by dry air from the interior during this time. El Niño years with their warm phase lead to precisely the opposite pattern: reduced rainfall and mass loss in the Antarctic Peninsula, and an increase in the Amundsen Sectorfield, respectively" explains Professor Maik Thomas, head of the section "Earth System Modelling" at the German Research Centre for Geosciences (Helmholtz Association).
The recording of the entire ice mass of the South Pole and its variations is a central task in climate research and still raises many unanswered questions. In principle, the study could show that the continuous gravity data of the GRACE satellite mission contain another important medium-term climate signal….

The storm produced strong winds with some gusts up to 77 miles per hour, according to the National Weather Service. At least 28 tornados were reported in several states, officials said.
…Several schools were closed in Minnesota on Wednesday because of storm-related power failures. In Duluth, Minn., all public and private schools were closed after the city received 7.4 inches of snow, officials said.
The storm was expected to weaken by Thursday as it continued to move northeast into Canada. At least 200 flights were canceled at O’Hare International Airport in Chicago on Wednesday after more than 500 flights were canceled there on Tuesday. As a cold front moved east, it brought storms to the Southeast. Tornado watches were issued on Wednesday in Alabama, Georgia, Maryland, North Carolina, South Carolina and Virginia...

"Around the world a rising number of diseases like SARS, monkeypox, and HIV are spread due to trade in wildlife, and these diseases have serious public health, economic, and conservation consequences," Dr. Daszak said. "Using EcoHealth Alliance's unparalleled experience in the field, the organization is working to identify, predict and mitigate disease outbreaks."
As the leading cause of human fatalities worldwide, infectious diseases lead to the deaths of 13 million people per year, and over three-quarters of emerging infectious diseases (EIDs) originate from wild or domestic animals and spread to humans. According to Daszak, biological impoverishment, habitat fragmentation, climate change, increasing toxification, and the rapid global movement of people and other living organisms have diminished ecosystem function, which results in unprecedented levels of disease. These factors pose a threat to the survival and health of all species.
To provide a real-world living example of this very serious situation, Daszak introduced the TEDMED audience to what he calls, "the cutest, scariest animal on the planet" -- the sugar glider, which is a small gliding marsupial with huge round eyes and a long tail. "I'm most afraid of this particular little animal, because the people are going into the forests of Indonesia to catch them, bring them into captivity, and ship them around the world – straight into our homes, where we hold them, kiss them, and cuddle up to them," he said. "What easier way could there be for any one of this species' 100 new viruses to spread to humans?"….

Officials meeting at the Fourth Asian Ministerial Conference on Disaster Risk Reduction have approved a five-year regional roadmap to establish climate resilient disaster risk management systems by 2015 that will contribute to sustainable development at the regional, national and community levels.
“This is the first time that governments agree at a regional level to recognize disaster risk reduction as a main tool to adapt to climate change and adopt a common regional climate risk management approach to reduce weather-related disaster impacts,” said Margareta Wahlström, Special Representative of the UN Secretary-General for Disaster Risk Reduction.
The roadmap, known as Incheon REMAP, focuses on three main themes: raising awareness and building capacities of communities so they can better cope with more weather-related hazards; sharing information through new technologies and sound practices in climate and disaster risk management so decision-makers can be better informed; and promoting integration of disaster risk reduction and climate change adaptation as part of sustainable development policies.
“I believe that the REMAP can become a guideline for all nations in the region and beyond to follow as a way to contribute to effective disaster reduction and climate change adaptation,” said M. Park Yeon-soo, Administrator of Korea’s National Emergency Management Agency (NEMA), which hosted the Fourth Ministerial Conference….

Together, these four satellites contain 15 separate scientific instruments that observe the same path of Earth's atmosphere and surface at a broad swath of wavelengths. At the front of the train, Aqua carries instruments that produce measurements of temperature, water vapor, and rainfall. Next in line, CloudSat, a cooperative effort between NASA and the Canadian Space Agency (CSA), and CALIPSO, a joint effort of the French space agency Centre National d'Etudes Spatiales (CNES) and NASA, have high-tech laser and radar instruments that offer three-dimensional views of clouds and airborne particles called aerosols. And the caboose, Aura, has a suite of instruments that produce high-resolution vertical maps of greenhouse gases, among many other atmospheric constituents.
In coming months, the A-Train will expand with the launch of NASA's aerosol-sensing Glory satellite and the carbon-tracking Orbiting Carbon Observatory 2 (OCO-2) satellite. In 2010, the Japan Aerospace Exploration Agency (JAXA) plans to launch the Global Change Observation Mission-Water (GCOM-W1), which will monitor ocean circulation. Meanwhile, a fifth satellite, France's Polarization and Anistropy of Reflectances for Atmospheric Science coupled with Observations from a Lidar (PARASOL), which studies aerosols, is easing out of an A-Train orbit as its fuel supplies dwindles….

Plans to relocate Indonesia's central government, parliament and public offices to another province on the island of Java or to another island in the Indonesian archipelago have been proposed on and off since the 1930s because of problems in Jakarta including overcrowding and rising sea level, which has led to worsening flooding. But environmental experts now say a move is urgent to allow officials to soften the impact of climate change on the congested city of 9.6 million people.
"Moving the capital will reduce the city's burden to provide infrastructure and services to its people so that authorities can start re-planning city development," said Sonny Keraf, Indonesia's environment minister between 1999 and 2001, and now a university professor and environmental expert. Still, "in terms of climate change adaptation, it won't be easy," he added.
While a number of locations for a new capital have been considered over the years, President Susilo Bambang Yudhoyono, parliamentarians and other officials now believe the island of Kalimantan, formerly known as Borneo, is the best choice….

The 34-page report from the Rocky Mountain Climate Organization and the Natural Resources Defense Council, which earlier this year released similar studies on how climate change could impact Glacier National Park and Shenandoah National Park, warns of not only biological change driven by these higher temperatures, but also of economic fallout.
“The natural and cultural resources of California’s national parks are directly linked to over one billion dollars in economic activity and 19,000 jobs," said Theo Spencer, a senior advocate in NRDC's Climate Center. "By acting now to reduce the pollution that causes global warming we will preserve these jobs and create new ones while continuing America's long-standing position of technological leadership.”
Part of the hit on California's economy could be waning tourism to these park icons. While hotter temperatures might initially see more people head into the High Sierra parks of Yosemite, Sequoia, and Kings Canyon, or to coastal parks such as Point Reyes National Seashore and Redwood National Park, "... as temperatures get too hot, outdoor recreation even in the mountains becomes less pleasant, and people may find other ways to get a break from the heat," the report notes…..

…This is also a perfect opportunity to launch a widespread promotion and local production of water harvesting systems that could be subsidised for individual houses. This investment would be critical not only for increasing our water supply, but also and very importantly for bringing back the reality and the value of water that many take for granted.
Disaster funds should not only try to overcome short-term issues such as lack of water. They should also be used for longer term purposes by, for instance, teaching individuals about climate change and peak oil (the time when maximum extraction of oil is reached).
…Individual mobilisation and preparedness are important ways to mitigate and adapt to climate change and peak oil threats. Water demand management and saving should therefore be priorities (before any expensive investment to secure a water supply increase) in order to foster individual understanding, pragmatism and resilience. Reduction of unaccounted for water use, use of prepaid meters and sewage recycling should therefore be entertained before the desalinisation plant is considered….
Prime Minister Abhisit Vejjajiva, who called the floods the worst in 50 years, pledged to give 5,000 baht ($167) to families in the worst-hit areas as part of a 2.9 billion baht special budget. The finance ministry today cut its forecast for economic growth this year to 7.4 percent from 7.6 percent, and said the disaster may cause as much as 20.2 billion baht of damage.
Floodwaters receded in 11 provinces, leaving 25 still inundated, the disaster prevention department said. The death toll since Oct. 10 rose to 59, according to the Emergency Medical Institution of Thailand.

The adaptation strategies to be developed will cover both planned buildings that are now at the design stage and large non-domestic buildings that are about to be refurbished. Iain Gray, Chief Executive of the Technology Strategy Board, said: “This investment is a fine example of the Technology Strategy Board supporting innovation that develops sustainable solutions for society while at the same time creating new markets for the UK economy. Innovation is crucial to British businesses and through investments such as this we are working to help businesses take advantage of future market opportunities.
“We are already designing and constructing buildings that use less energy and reduce CO2 emissions. The challenge now is to make sure our buildings are resilient and adaptable to the climate change that we will see over the coming decades.”…

"Fish catches have already been reduced. The rivers that flow here pollute the sea and the waters are warming, so the fish are following other routes. What we used to catch 15 miles from the coast and six metres deep now we have to seek at 50 to 60 miles out and more than 20 metres deep -- and with inadequate boats," fisherman Daniel Córdoba, from Carenero, 80 kilometres east of Caracas, told Tierramérica.
Venezuela, a nation of 28 million people, produces about 400,000 tonnes of fish annually, according to the Socialist Institute of Fishing and Aquaculture, and has some 30,000 fishers working along its coasts, mostly in small-scale operations.
"A few years ago, along this strip of coastline, on any given day you saw a few dozen boats out fishing. I go out every day, and I think now, at times, there could be as many as a thousand," Cedrick McGregor, a veteran fisherman of Jamaican origin, told Tierramérica. Luis Acuña, an expert with the harpoon, agrees with Córdoba and McGregor that "what we used to catch on one or two days of fishing now takes four or five."….

The first of its kind, the Asia-Pacific Disaster Report 2010 - prepared by the UN Economic and Social Commission for Asia and the Pacific (ESCAP) and the UN International Strategy for Disaster Reduction (UNISDR)notes that natural disasters had disproportionate impacts on human development in the region.
The region lacked comprehensive natural disasters assessment capacity, the reports notes, adding that while it generated one quarter of the world’s gross domestic product (GDP), it accounted for 85 per cent of deaths and 42 per cent of global economic losses due to natural disasters. The report considers the socio-economic impact of disasters, and suggests ways of reducing vulnerability to disasters to protect development gains.
It emphasizes that disaster losses are linked to and exacerbated by poverty, and that the vulnerability of the poor stems from multifaceted socio-economic and environmental imbalances. “Unless these imbalances are addressed, people who are constantly exposed to disaster risk are more likely to remain poor and more vulnerable to disasters, perpetuating a vicious cycle from which it is extremely difficult to break free,” said Noeleen Heyzer, the Executive Secretary of ESCAP, in a joint statement with Margareta Wahlstrom, the UN Special Representative for Disaster Risk Reduction…

More intense storms will occur in the Southern Hemisphere throughout the year, whereas in the Northern Hemisphere, the change in storminess will depend on the season — with more intense storms occurring in the winter and weaker storms in the summer. The responses are different because even though the atmosphere will get warmer and more humid due to global warming, not all of the increased energy of the atmosphere will be available to power extratropical storms. It turns out that the changes in available energy depend on the hemisphere and season, according to the study, published Monday in the Proceedings of the National Academy of Sciences.
Fewer extratropical storms during the summer in the Northern Hemisphere could lead to increased air pollution, as “there would be less movement of air to prevent the buildup of pollutants in the atmosphere,” says author Paul O’Gorman, the Victor P. Starr Career Development Assistant Professor of Atmospheric Science in MIT’s Department of Earth, Atmospheric and Planetary Sciences. Likewise, stronger storms year-round in the Southern Hemisphere would lead to stronger winds over the Antarctic Ocean, which would impact ocean circulation. Because the ocean circulation redistributes heat throughout the world’s oceans, any change could impact the global climate.
…Although the analysis suggests that global warming will result in weaker Northern Hemisphere storms during the summer, O’Gorman says that it’s difficult to determine the degree to which those storms will weaken. That depends on the interaction between the atmosphere and the oceans, and for the Northern Hemisphere, this interaction is linked to how quickly the Arctic Ocean ice disappears. Unfortunately, climate scientists don’t yet know the long-term rate of melting…

…The fastest growing region in the US is the southwest.. Unfortunately, it is the region that can least afford massive population increases. Places like the Las Vegas metropolitan area in Nevada and the Valley of the Sun in Arizona have grown by leaps and bounds in past few decades. Phoenix is now the nation's fifth largest city. Recent economic turbulence may have put a damper on that growth, but the higher water demand is still there.
Increased demand is a key factor, but perhaps not as important as the lack of rainfall across the southwest which feeds Lake Mead. According to the US Department of the Interior's Bureau of Reclamation, the Upper Colorado River Basin has had only 89 percent of its average precipitation for 2010. They predict that this autumn, the temperature will remain above average and precipitation below average, leading to worsening conditions.
The current drought began way back in October 1999. At that point, Lake Powell, the second largest reservoir in the US located along the Arizona-Utah border, was near full capacity. Over the next five years, inflow into the lake was about half of the average. It has increased somewhat since then, but remains low.
At this point, nobody is able to predict when the drought will end. Normally, droughts occur as a natural climate variation, and the pendulum always swings back towards a wetter climate. However, the current drought has lasted much longer than normal, and local residents have become concerned with possible consequences….

The drought currently affecting swaths of north and west Amazonia has been described as the one of the worst in the last 40 years, with the Rio Negro or Black river, which flows into the world-famous Rio Amazonas, reportedly hitting its lowest levels since records began in 1902 on Sunday. In 24 hours the level of the Rio Negro near Manaus in Brazil dropped 6cm to 13.63 metres, a historic low.
The Solimoes and Amazonas rivers have also seen their waters plunge since early August, stranding village dwellers who rely on the Amazon's waterways for transport and food and marooning wooden boats on brown sand banks.
According to local authorities nearly half of Amazonas state's 62 municipalities have declared states of emergency, among them Manaquiri, one of the worst hit areas during the last major drought in the region in 2005. That year thousands of families were forced to abandon their homes and schools closed for lack of students.
Authorities say around 62,000 families have been affected by this year's receding rivers and on Friday the federal government announced $13.5m (£8.5m) in aid for the region….

Norway has already released $30 million of the funds, with the bulk to be paid out later after Indonesia proves greenhouse gas emissions have gone down and an independent audit is done. But more aid is needed to save Indonesia's forests, said Norwegian environment minister Erik Solheim.
"$1 billion is a huge amount of money but Indonesia needs quite substantially more to be able to conserve and sustainably manage its forests," Solheim told Reuters in an interview in Jakarta, where he is meeting Indonesian officials. "The United States should come in, Japan, other European nations could come into this scheme to make it robust enough."…

HealthMap.org has enhanced its mobile phone application “Outbreaks Near Me” to accept and relay wildlife health reports to the WHER site. The application continues to accept reports of human illness. Researchers in the Nelson Institute for Environmental Studies at the University of Wisconsin-Madison and the U.S. Geological Survey National Wildlife Health Center in Madison created the WHER so that people around the world can easily share information about possible health threats to wildlife and humans.
“Avian influenza, SARS, West Nile virus, and rabies are just a few of the rogues’ gallery of human diseases in which wildlife play a role. Seventy-five percent of recent emerging infectious diseases in humans began as animal infections, and most of these have involved wildlife,” explains USGS scientist Joshua Dein, one of the WHER’s developers. “If these tools had been available 10 years ago, we might have had an earlier identification of West Nile virus by people reporting that they were seeing dead crows in their backyards,” said Dein. “We don’t know what the next emerging disease outbreak will be, but given recent history, it will likely be preceded by wildlife health events.”
Users of the WHER create accounts online to register sightings of sick or dead wildlife. Anyone can visit the site to see what others have reported and can subscribe to an RSS feed to receive new reports via e-mail. Reports can be limited to specific states, and data can be readily exported or sent through special feeds to other websites. Local wildlife officials who wish to be notified of observations also can subscribe and, when available, their contact information will be given to those who submit reports....Dein notes that the WHER is experimental and will require high participation rates over a considerable period of time to provide useful data. He adds that despite the connections between human and animal diseases, people should not view wildlife as a threat to human health. “A more accurate vision is that we all share risks from these disease threats,” said Dein. “These new tools can help researchers use wildlife as sentinels to alert us to diseases in the environment.”...
