Island nations tell UN powerful states must show leadership on climate change
UN News: The greatest burden in the global fight against climate change should be borne by the world’s powerful countries, which are also often the leading producers of greenhouse gas emissions, the leaders of several island nations told the General Assembly today.
Addressing the Assembly’s annual high-level debate, the representatives also called on affluent nations to increase their level of spending towards an adaptation fund to help the most vulnerable States adjust their economies and infrastructure to cope with the impact of global warming….

Melissa weakens to tropical depression over Atlantic
Reuters: … The 13th named Atlantic storm this year poses no threat to land and is not expected to strengthen in the next 24 hours, the hurricane center said.
At 11 a.m. (1500 GMT) Melissa was 570 miles west of the Cape Verde islands and was moving west northwest at 13 mph (20 kph). "The intensity forecast maintains Melissa as a Tropical Depression during the next day or so. However, if the circulation center continues to become less defined and the depression does not generate enough organized convection ... it could become a remnant low much sooner," the hurricane center said in a statement. A tropical storm has sustained winds of 39 to 73 miles per hour (63-118 kph).

North America's northernmost lake affected by global warming
The speed and range of these transformations-unprecedented in the lake's last 8,000 years-suggest that climate change related to human activity could be at the source of this phenomenon.
"This is of course an extreme environment for living organisms, but our data indicate that current conditions make the lake a more favorable location for algae growth than it was in the past," points out [lead author and Center for Northern Studies researcher Dermot] Antoniades. "We cannot claim with certainty that these changes were brought on by human activity, but natural variations observed over the last millennia were never so abrupt and extensive," concludes the researcher.
Red Cross/Red Crescents says Africa flooding will worsen
While it is not unusual for Africa to experience heavy rains at this time of the year, 2007 has brought particularly intense rainfall over a wider geographic area than normal. As a result, in 20 countries in the region, the flooding can be described as “exceptional”. The World Meteorological Organization (WMO) believes that the torrential rains stretching across Africa, and the flooding that has followed, is consistent with to the "La NiƱa" weather pattern thousands of miles away in the Pacific.
No one can say that these specific floods are directly related to climate change. However, they are consistent with the predictions of climate change analysts. The experts at our Red Cross Red Crescent Climate Centre in The Hague believe that the phenomenon will raise flood risks in Africa, especially in west, central and east Africa, which is suffering the worst of the present flooding. Climate change will also increase the risk of drought in some areas, while others may experience both floods and droughts, as was recently the case in Kenya, Ethiopia and Mozambique.
The significant rise in the number of climate related emergencies Red Cross and Red Crescent Societies have responded to over the past three years confirms this analysis. There is a new trend developing and we must take it seriously.

Industry analysts estimate that such an event would bankrupt as many as 40 insurers. Lloyd's has warned: "The insurance industry must start actively adjusting in response to greenhouse gas trends if it is to survive." The Association of British Insurers has called on governments to "stem ominous weather related trends" by cutting carbon emissions. U.S.-based companies AIG and Marsh -- respectively, the largest insurer and broker -- have joined with other corporate leaders to urge Congress to reduce
Marsh issued a similar statement, as did European insurance giants Swiss Re, Munich Re and Allianz. The chief research officer of Risk Management Solutions, an industry risk forecaster, responded to an April report of the Intergovernmental Panel on Climate Change by announcing that climate change is already increasing "financial losses from extreme weather catastrophes." A.M. Best, the historical voice of insurance, began a series in the August edition of Best's Review on the risks, regulatory issues and economic impact of climate change.
Nervous investors have begun asking insurers to disclose their strategies for dealing with global warming. At a meeting of the National Association of Insurance Commissioners,
Insurance companies are reacting. Some have simply abandoned catastrophe-prone markets or are jacking up rates. Other insurers have taken steps in the battle against climate change by offering premium incentives for "green" construction and hybrid cars, investing in companies that cut carbon emissions or develop clean energy, and offering "pay per mile" car insurance. Still others are reducing their own carbon footprints, promoting markets for carbon-credit trading and even moving to protect carbon-consuming forests.
Insurance companies make money by accurately assessing risk. For decades environmentalists have been sounding the alarm about global warming. Now major insurers are becoming engaged as they look after their own assets and those that they cover. Federal reluctance to commit to international agreements on climate change, or otherwise cap total carbon emissions, appears to be driven by influential businesses that fear the limitations will hurt their bottom lines. But the risk perceived by the insurance industry -- the world's largest economic sector -- may shift that political balance. At the least, it should tell us something.
Arctic heat wave stuns climate researchers
Terra Daily: Unprecedented warm temperatures in the High Arctic this past summer were so extreme that researchers with a Queen's University-led climate change project have begun revising their forecasts. "Everything has changed dramatically in the watershed we observed," reports Geography professor Scott Lamoureux, the leader of an International Polar Year project announced yesterday in
One of 44 Canadian research initiatives to receive a total of $100 million (IPY) research funding from the federal government, Dr. Lamoureux's new four-year project on remote Melville Island in the northwest Arctic brings together scientists and educators from three Canadian universities and the
The information will be key to improving models for predicting future climate change in the High Arctic, which is critical to the everyday living conditions of people living there, especially through the lakes and rivers where they obtain their drinking water.
…From their camp on Melville Island last July, where they recorded air temperatures over 20C (in an area with July temperatures that average 5C), the team watched in amazement as water from melting permafrost a metre below ground lubricated the topsoil, causing it to slide down slopes, clearing everything in its path and thrusting up ridges at the valley bottom "that piled up like a rug," says Dr. Lamoureux, an expert in hydro-climatic variability and landscape processes. "The landscape was being torn to pieces, literally before our eyes. A major river was dammed by a slide along a 200-metre length of the channel. River flow will be changed for years, if not decades to come."
Comparing this summer's observations against aerial photos dating back to the 1950s, and the team's monitoring of the area for the past five years, the research leader calls the present conditions "unprecedented" in scope and activity. What's most interesting, he says, is that their findings represent the impact of just one exceptional summer.
"A considerable amount of vegetation has been disturbed and we observed a sharp rise in erosion and a change in sediment load in the river," Dr. Lamoureux notes. "With warmer conditions and greater thaw depth predicted, the cumulative effect of this happening year after year could create huge problems for both the aquatic and land populations. This kind of disturbance also has important consequences for existing and future infrastructure in the region, like roads, pipelines and air strips."

Foresters take fast action to mitigate future fire seasons: US Senate testimony
Firerescue1.com: The nation's worsening fire seasons are, in part, a consequence of global warming and are likely to get more severe unless forest managers step up tree removal efforts and prescribed fire programs, a group of scientists testified Monday before a congressional panel.
A series of deadly and destructive Inland fire seasons, demonstrated recently by the 14,000-acre Butler 2 Fire near Big Bear, had been attributed to, among other things, a drought cycle expected to eventually pass. But the findings presented Monday to the Senate Committee on Energy and Natural Resources suggest a lasting trend in the region, and across the nation.
The link between climate change and wildfires is easily apparent on a global and national scale, according to Susan Conard, national program leader for the U.S. Forest Service's Fire Ecology Research division. "Annual burned areas have exceeded 7 million acres only seven times since 1960," Conard testified. "Six of those have been in the past 20 years."
…Wildfires thrive in hot, dry weather. But the conditions also contribute to the die-off of trees, which must compete for water in forests that have become unnaturally dense because of a century of misguided fire suppression. Once dead and brittle, the trees become more fuel for catastrophic fires.
The panelists testified that more resources are needed to keep up with necessary tree thinning and removal campaigns. One witness,
He said more prominent use of intentionally set fires to mimic naturally occurring blazes has certain risks, but is less costly than mechanical thinning with hand crews and chainsaws.
Ann Bartuska, deputy chief of research and development for the Forest Service, said the agency has been authorized to spend roughly $20 million a year to study the best way to modify forest management plans to adapt to the science linking climate change to worsening fire seasons.
On a local level, the impact of global warming is less apparent because of other factors that have led to increasingly destructive fire seasons, Swetnam said following the hearing. "It gets quite murky in

China warns of "catastrophe" from Three Gorges Dam
Reuters:
The dam in southwest China, the world's biggest hydropower project, has begun generating electricity and serving as a barrier against seasonal flooding threatening lower reaches of the Yangtze River, Xinhua news agency reported late on Tuesday, citing a forum of experts and officials.
….The $25 billion dam, whose construction flooded 116 towns and hundreds of cultural sites, is still a work in progress, but state media have said it could be completed by the end of 2008, just after the Beijing Olympic Games.
Wang Xiaofeng, director of the administrative office in charge of building the dam, told the forum that it was time to face up to the environmental consequences of constructing the massive concrete wall across the country's biggest river. "We absolutely cannot relax our guard against ecological and environmental security problems sparked by the Three Gorges Project," Wang told the meeting, according to Xinhua. "We cannot win passing economic prosperity at the cost of the environment."
Wang cited a litany of threats, especially erosion and landslides on steep hills around the dam, conflicts over land shortages and "ecological deterioration caused by irrational development". The strikingly frank acknowledgement of problems comes weeks before a congress of the ruling Communist Party that is set to consolidate policies giving more attention to environmental worries after decades of unfettered industrial growth.
…Tensions over residents resettled to steep hills where good farmland is scarce had been reduced and water quality in the dam was "generally stable", Xinhua said. But the officials and experts were worried about the landslides threatening densely populated hill country. "Regular geological disasters are a severe threat to the lives of residents around the dam," senior engineer Huang Xuebin told the forum. Huang described landslides into the dam waters making waves dozens of meters high that crashed into surrounding shores, creating even more damage.
The dam has displaced 1.4 million people and is retaining huge amounts of sediment and nutrients, damaging fish stocks and the fertility of farmland downstream, researchers say.

Japan weather seen warmer in Oct to Dec: forecaster
Japan's four regions each stand a 40 percent chance of having warmer-than-average weather in the last quarter of the year, the Japan Meteorological Agency said in its monthly three-month outlook.
A mild start to the winter season usually slashes kerosene demand. Demand for kerosene usually peaks around January. The forecaster's data showed that the 30-year average of peak temperatures in the capital Tokyo was 26.8 Celsius (80 Fahrenheit) in September, 21.6 C in October, 16.7 C in November and 12.3 C in December.
Japan has seen mostly hotter temperatures since early August, boosting electricity demand at several utilities to record-high levels amid a heat wave and high humidity. Japan's 10 electric utilities generated a record-high 96.2 billion kilowatt hours (kWh) in August, surpassing the previous high of 93.41 billion kWh hit a year earlier, industry data showed.
Women turn up gender-equity heat at climate talks
WOMENS-E-NEWS: Women's perspectives and experiences must be included in international negotiations over climate change if efforts to curb global warming are to succeed, participants said at a roundtable last week on the effects of climate change on women.
Sixty government, United Nations and civil society representatives attended the meeting on Sept. 21, which aimed to influence discussions during Monday's gathering on climate change at the U.N. headquarters as part of the annual meeting of the general assembly.
"Climate change will increase existing inequalities," said Irene Dankelman, vice-chair of the Women's Environment and Development Organization, in her opening remarks at the roundtable. "Not only are women adversely impacted by climate change, they also contribute differently from men to its causes and its solutions."
The group highlighted women's disproportionate vulnerability to the types of natural disasters that climate change is expected to cause as well as women's often overlooked capacity to join mitigation efforts.
In the Indonesian villages that were worst hit by the 2004 tsunami, up to 80 percent of the victims were female, according to Oxfam International, based in
"During emergencies women are less likely to have access to information about assistance than men," said Lorena Aguilar, a senior gender advisor for the World Conservation Union, based in
But neither the Kyoto Protocol, which expires in 2012 and aims to reduce greenhouse gas emissions by that date through legally binding measures, nor the United Nations Framework Convention on Climate Change--the first international treaty to address global warming, which entered into force in 1994--mention women or gender.
In order to reduce the high levels of female mortality during natural disasters the roundtable organizers urged governments to analyze and identify the specific risks such events pose to women, as well as gender-specific protection measures. "Climate change policy-making has failed to adopt a gender-sensitive strategy," said Aguilar.
The U.N. meeting is meant to build momentum for the annual U.N. climate change conference, taking place this year in
The policy recommendations also propose that governments tap women's specific knowledge and skills when developing mitigation and adaptation strategies. Some climate change experts, for example, have argued that women's experience with domesticating plant seeds and breeding food crops can help communities find new food sources and adapt to changes in climate. The group also wants carbon-curbing technologies made more accessible to women…

Amazon forest shows unexpected resiliency during drought
Terra Daily: Drought-stricken regions of the Amazon forest grew particularly vigorously during the 2005 drought, according to new research. The counterintuitive finding contradicts a prominent global climate model that predicts the Amazon forest would begin to "brown down" after just a month of drought and eventually collapse as the drought progressed. "Instead of 'hunkering down' during a drought as you might expect, the forest responded positively to drought, at least in the short term," said study author Scott R. Saleska of The University of Arizona. "It's a very interesting and surprising response." UA co-author Kamel Didan added, "The forest showed signs of being more productive. That's the big news."
The 2005 drought reached its peak at the start of the Amazon's annual dry season, from July through September. Although the double whammy of the parched conditions might be expected to slow growth of the forest's leafy canopy, for many of the areas hit by drought, the canopy of the undisturbed forest became significantly greener -- indicating increased photosynthetic activity.
Saleska, a UA assistant professor of ecology and evolutionary biology, and his colleagues at the UA and at the University of Sao Paulo in Brazil used data from two NASA satellites to figure out that undisturbed Amazon forest flourished as rainfall levels plummeted…."A big chunk of the Amazon forest, the southwest region where the drought was severest, reacted positively," said Didan, a NASA-EOS MODIS associate science team member.
The study, "Amazon Forests Green-up during 2005 drought," is online in the current issue of Science Express, the early-online version of the journal Science. The paper will be published in the October 26, 2007, issue of Science.
…Global climate models predict the Amazon forest will cut back photosynthesis quickly when a drought starts. That slowdown in plant growth would create a positive feedback loop -- as the forest shuts down more and more, it removes less and less carbon dioxide from the atmosphere. The CO2 ordinarily sequestered by growing trees would remain in the atmosphere, increasing global warming and further accelerating the forest's decline and additional CO2-fueled warming.
By contrast, the UA-led team's findings suggest the opposite happens, at least in the short-term. The drought-induced flush of forest growth would dampen global warming, not accelerate it. During the 2005 drought, Amazon forest trees flourished in the sunnier-than-average weather, most likely by tapping water deep in the forest soil. To grow, trees must take up carbon dioxide, thus drawing down the levels of atmospheric CO2. That negative feedback loop would slow warming from greenhouse gases.
Evolutionarily, the forest's resilience in the face of a single drought year makes sense, Saleska said. During El Nino, which occurs about every four to eight years, the Amazon forest receives significantly less rain than average. The limit of the forest's resiliency is unknown, Saleska said, adding, "But if you take away enough water for long enough, the trees will die."

Is he the doomsayer global warming skeptics have called him? Mann laughs. This
Climate scientists say mankind is on the path for soaring temperatures that will melt polar ice sheets, raise seas to dangerous levels, and trigger mass extinctions. But they say the most catastrophic of consequences can and will be avoided. They have hope. So should you, Mann said.
"Sometimes we fear that we are delivering too morose a message and not conveying enough that there is reason for optimism," Mann said. Mann is not alone in laughing, even though the news he delivers could make people cry.
"It's hard at times," said
The science, Mann said, is because climate researchers are sure of one thing that the public isn't: The numbers show that there is still time to avert the worst. NASA's James Hansen, who forecasts some of the bleakest outlooks on global warming, said in an e-mail: "I am always surprised when people get depressed rather than energized to do something. It's not too late to stabilize climate."
"I am not about to give up," Hansen wrote. He has hope, he says, because he has grandchildren. The scientists say the public now understands how bad the problem is. So these researchers have faith that society will rally in time.
Bob Corell, an American Meteorological Society climate scientist, is hopeful because even industry is pushing for change — and will make money in the deal. Mann points to an international agreement 20 years ago this month that stopped the worsening global problem of ozone depletion. The same can be done for global warming, he said.
If the world spews greenhouse gases at its current ever rising rate, expect a 7-degree rise by the end of the century. If those gases are curbed, then warming can be kept to about 1 degree, an international panel of experts said earlier this year.
How about Al Gore? Does he lose hope? "No, because we can't afford to," said the former vice president, who has helped bring global warming to center stage. "It's a genuine planetary emergency."

Carbon Disclosure Project's latest report is being launched
Reuters: Climate change is spurring a "worldwide economic and industrial restructuring" as more and more of the world's largest companies seek to confront global warming, an investor survey said on Monday. Even so, some big firms were still doing far too little to identify risks and opportunities from climate change, according to the Carbon Disclosure Project (CDP), representing 315 institutional investors managing $41 trillion in assets.
A record 77 percent of the world's top 500 firms, rated by market capitalization in the FT500, answered a request for information about their responses to global warming, up from 72 percent in 2006, it said. "One trend above all is becoming increasingly clear: climate change and the various regulatory, policy and business responses to it are driving what amounts to a worldwide economic and industrial restructuring," a 92-page survey said. "That restructuring has already begun to redefine the very basis of competitive advantage and financial performance for both companies and their investors," it said.
The project, in its fifth year, seeks to guide investors by getting companies to give details of their greenhouse gases and strategies for everything from energy efficiency to recycling. "Seventy-six percent of responding companies reported implementing a greenhouse gas emissions reduction initiative," up from 48 percent in the previous FT500 survey, it said.
…"Investors are looking for the next big thing. If the company is part of the problem on climate change it hasn't a clear run at the markets of the 21st century," Paul Dickinson, chief executive officer of the CDP, told Reuters. The CDP sent requests in total to 2,400 companies around the world and got 1,300 responses. In the FT500, Europe-based companies led in response rates. U.S.-based firms lagged and none of seven Chinese companies replied.
The CDP also published a first index of firms with what it said were best carbon disclosure practices, including mining group Rio Tinto, energy firm Iberdrola, computer firm Hewlett Packard or Westpac Banking. Still, it said too many firms failed to reply, such as Apple Computer, Bank of China, Berkshire Hathaway, Gazprom or Philips Electronics.

The change will be a gradual process, one that is so slow it will be easy to ignore for a while. "It's like sticking your finger in a pot of water on a burner and you turn the heat on, Williams said. "You kind of get used to it."
Air pollution triggers blood clots: study
Reuters: Tiny particles of air pollution -- less than one tenth the width of a human hair -- can trigger clotting in the blood, U.S. researchers said on Thursday in a finding that helps explain how air pollution causes heart attacks and strokes.
Large population studies have shown pollution from the exhaust of trucks, buses and coal-burning factories increases the risk of fatal heart attacks and strokes. But researchers have not understood how these microscopic particles actually kill people. "We now know how the inflammation in the lungs caused by air pollutants leads to death from cardiovascular disease," said Dr. Gokhan Mutlu of
Lungs inflamed by pollution secrete interleukin-6, an immune system compound that sparks inflammation and has been shown to make blood more likely to clot. The research appears in the Journal of Clinical Investigation. It follows a study last week in the New England Journal of Medicine that found breathing diesel fumes interfered with heart attack survivors' ability to break down blood clots.
Mutlu got a clue about the clotting issue two years ago when he was studying the effects of air pollution on heart failure in mice. Mice who had been exposed to pollution bled significantly less. "They were forming blood clots," he said in a telephone interview.
In the latest study, he and colleagues exposed mice to particles of air pollution collected by the U.S. Environmental Protection Agency. These were mixed with a saline solution and injected into the lungs of mice.
Mice exposed to pollution showed a 15-fold increase in interleukin-6 just 24 hours later. That time frame is important because some studies have shown a spike in air pollution can boost heart attacks with 24 hours…He said most people understand that high levels of air pollution can make lung diseases such as asthma worse. "The same thing is not known for patients with coronary artery disease or congestive heart failure," Mutlu said. "I think we need to increase the awareness of this link among those individuals."
The researchers now plan to study whether aspirin can counteract the clotting effect in mice. Low-dose aspirin helps thin the blood and is already recommended for people with heart problems.

Climate change could wreak havoc on local rivers in Colorado
Aspen Daily News: Global warming could mean both more droughts and more flooding to the Roaring Fork and other Western rivers, and in just decades it could bring dramatic consequences to local farmers, anglers and fish, a
….Strzepek discussed the predictions at the Given Institute on Thursday in a presentation organized by the Roaring Fork Conservancy. He dubbed the presentation a “sequel” to one he delivered in
Arid climates are expected to become even drier, Strzepek said, and areas that flood may see worse flooding, sometimes with devastating consequences, particularly in the developing world. “The poor will suffer the most, who have the least capability of adapting and dealing with that,” he said.
…Similar heavy flooding is likely for the Roaring Fork, he said, and bridges aren’t built to handle it. It’s not clear how warming temperatures will affect
That’s bad for trout, which could see dangerously low water levels and temperatures reaching fatal levels, Strzepek said. It’s also bad for rafting companies that could see shorter seasons, and for ranchers who will likely need more irrigation water. By 2070, he said, runoff could peak a month early, putting water levels out of synch with growing seasons. That could leave even some senior water rights holders out of luck if their rights are timed, he said.
Low water levels could also affect ski areas’ ability to use water for snowmaking, he said. Prior to his presentation, Strzepek said, he went on a Roaring Fork “field trip,” catching an 18-inch trout in its famous waters, but he worried about the impact on river habitat under global warming. “What I want to be able to do is have my grandkids catch a fish like that,” he said.

Summer floods to cost £3bn
Speaking on Thursday at a conference organized by environmental charity Global Action Plan, Jane Milne, head of the property and creditor team at ABI, said the costs represent two-thirds of what the industry expects to pay out in a "bad" year. She said: "We claim to be the risk experts, and we will invest much more in understanding what the future risks will be. It is clear that the old industry practice of taking the last 50 to 100 years of data and using that to underwrite insurance will not be effective anymore." She criticised the Government's pledge to increase spending on flood defences by just £200million and called for changes to future housing development to place more emphasis on flood risks.
Delegates at the conference, entitled The Wave of Change for London Business were warned that they would also need to adapt to a changing climate and to the predicted flooding of the Thames if sea levels rise in the future. Business leaders were urged to do their bit to reduce their contribution to the problem. Trewin Restorick, director of Global Action Plan, told delegates: "There are some companies I see who really get this issue and some who don't. But I think, increasingly, there are companies who do get it." He told businesses to look at their practices, the behaviour of their staff, and even their products and identify ways to make positive changes.
Australia: Opposition leader Rudd discusses climate change with farmers
ABC Rural (Australia): Opposition leader Kevin Rudd is in western New South Wales to meet farmers and to put a dollar figure on the Labor Party's climate change policy. Drought and climate change were the issues for Opposition Leader and birthday boy Kevin Rudd as he made a whistle-stop tour of drought-stricken properties near Walgett, in the National Party-held seat of Parkes in western New South Wales this morning.
The main issues for the farmers are ongoing drought, lack of infrastructure, hospitals and telecommunications as well as the impact of high grain prices on farmers who have forward-sold their crop but have no crop to deliver.
Kevin Rudd is expected to announce $60 million over three years to help ameliorate the impact of climate change. Turning 50 today, the farmers baked a special chocolate cake for Mr Rudd.
Weather forecasting needs huge boost to tackle climate change: WMO
Terra Daily, via Agence France-Presse: The UN's meteorological agency on Friday called for a multibillion dollar boost for weather forecasting, warning that about 30 percent of economic wealth was directly exposed to the impact of global warming.
The World Meteorological Organisation urged the international community to pay greater attention to helping countries, especially poor nations, adapt to the extreme weather conditions associated with climate change.
"We estimate that today up to 30 percent of the GDP (Gross Domestic Product) of a developed country shows a significant sensitivity to weather, climate and water conditions, and the share can be proportionally even bigger in developing countries," said WMO Secretary General Michel Jarraud.
He urged countries to extend and make better use of the technology available in order to cope with an increase in floods, drought or storms and to better protect lives, health, food supplies and the wider economy.
An estimated five to 10 billion dollars is spent every year around the world on weather forecasting but the amount needs to increase sharply according to the WMO. "In developing countries it's definitely much more than doubling. In developed countries it's more subtle than that," Jarraud told journalists. "In developing countries it's fundamental, it's not just strengthening, it's even rebuilding (weather) infrastructure," he added.
The appeal was made ahead of a meeting of world leaders at the United Nations in
"It's one thing to issue good warnings, but we have to do something with the warnings," he added. Most international efforts to deal with climate change have focused so far on mitigation -- attempts to cut pollution or carbon dioxide emissions that contribute to global warming -- more than adaptation.
Methodology predicts effects of hurricanes on coastal roadways
According to U.S. census data, more than 50 percent of the population lives within 50 miles of the shoreline, and that coastal population continues to grow. In the last three decades, more than 37 million people, 19 million homes, and countless businesses have been added to coastal areas. These areas are under severe stress owing to increased human activities and climate change.
With the rapid development of computer technology, significant advances in modeling storm surges and surface waves have been made in coastal engineering over the last decade. The simulation and prediction of storm surges and waves are intrinsically complex.
In the study, the advanced surge model (ADCIRC), coupled with the wave model (SWAN), was used to construct the prediction and effects of Hurricane Georges on the Mobile Bay estuary in 1998. Agreement between the model and data of the poststorm survey was found, demonstrating the effectiveness of the wave and surge prediction on coastal roadways around shallow estuaries. The coupled wave and surge modeling system has also been used to simulate the storm surge and wind waves during Hurricane Katrina that caused the collapse of several coastal bridges.

Georgia shoreline vulnerable to rising water
Daily Report (
…More intense hurricanes, coupled with rising seas, could spell disaster for low-lying areas. The National Environmental Trust, a nonprofit, nonpartisan group, on its Web site proffers a scientifically based simulation of what could happen to Tybee Island in 40 to 90 years if a Category 2 storm hits, and if seas already have risen three feet—a scenario postulated by the United Nations Intergovernmental Panel on Climate Change. In the simulation, Tybee is completely submerged.
Tybee has an average elevation of 10 feet to 12 feet above sea level, and according to the most recent storm surge map, about 25 percent of its land—mostly along the north end, on the beach—is vulnerable even to a Category 1 storm. Phillip M. Webber, director of the Chatham Emergency Management Agency, which handles Tybee’s emergency preparedness, acknowledges that a Category 5 storm—when coupled with wave action and rainfall—could submerge the island, at least for a while. Curry, who has seen the Tybee simulation, calls it a reasonable view of what could happen, but she points out that it is a “100-year issue.”
In the near term, however,
“There is climate change. It is getting warmer. Sea levels are starting to rise as rapidly as they have during this whole interglacial time period that we’re in right now,” he says. “But to take that and attribute it to man’s efforts is difficult right now because of the short time span.” Alexander does attribute coastal erosion—which is affected by rising seas—to human activity.
