(10/24/2006) Monday the World Bank endorsed carbon trading as a way to save tropical rainforests which are increasingly threatened by logging, agricultural development, subsistence agriculture, and climate change itself. The World Bank report comes on the heels of a proposal by a coalition of developing countries to seek compensation from industrialized countries for conserving their rainforests to fight global warming. Brazil is expected to announce a similar plan at upcoming climate talks in Nairobi.
Global warming will threaten health through dirtier air, hotter days, and more natural disasters
(10/23/2006) Global warming will threaten human health through dirtier air, hotter days, and more natural disasters that will worsen water quality, stress emergency systems, and create environmental refugees, warns a public health physician.
Global warming could cause catastrophic die-off of Amazon rainforest by 2080
(10/23/2006) For the Amazon, there is an immense threat looming on the horizon: climate change could well cause most of the Amazon rainforest to disappear by the end of the century. Dr. Philip Fearnside, a Research Professor at the National Institute for Research in the Amazon in Manaus, Brazil and one of the most cited scientists on the subject of climate change, understands the threat well. Having spent more than 30 years in Brazil and now recognized as one of the world's foremost experts on the Amazon rainforest, Fearnside is working to do nothing less than to save this remarkable ecosystem. Fearnside believes saving the Amazon will require a fundamental shift in perception where the Amazon is recognized as an asset beyond the current price of mahogany, soybeans, or cattle, where its value is only unlocked by its destruction. The Amazon is far worth more than this he says. It can play a key role in fighting climate change while providing economic sustenance for millions through sustainable agriculture and rational utilization of its renewable products. It can serve as a storehouse for biodiversity while at the same time ensuring reliable water supplies and moderating regional temperature and precipitation. In short, maintaining the Amazon as a viable ecosystem makes sense economically and ecologically -- it is in our best interest to preserve this resource while we still can.
Climate change to cause more extreme weather

Tremendous loss of ice in Greenland finds new NASA study
(10/19/2006) For the first time NASA scientists have confirmed that Greenland's ice sheet is shrinking. Using a new remote sensing technique that reveals regional changes in the weight of the massive ice sheet across the entire continent, researchers at NASA's Goddard Space Flight Center found that Greenland suffered a net loss of 25 cubic miles (101 gigatons) of ice per year between 2003 and 2005.
Brazil says no to rainforest privatization plan, asks Gore for help
(10/18/2006) On Tuesday Brazil rejected a alleged British proposal to fight climate change by 'privatizing' parts of the Amazon rainforest, according to Reuters. In an editorial published on the opinion page of Folha de S.Paulo newspaper, Environment Minister Marina Silva and Foreign Minister Celso Amorim said that the Amazon was 'not for sale'. Their comments were expected since Brazil has long objected to internationalization of the Amazon, seeing such attempts as a threat to its sovereignty. The 'Amazon privatization' report, which originally appeared in Britain's Sunday Telegraph newspaper on October 1, 2006, said that David Miliband, Britain's Environment Secretary, planned to propose an initiative that would turn parts of the Amazon into an 'international trust' wherein credible buyers could lockup parts of the rainforest for preservation. However, shortly after the article was published, Miliband's office strongly rejected the story.
Unchecked global warming will cost trillions says report

Warming climate causing Alaska lakes to dry up
(10/12/2006) More than 10,000 Alaskan lakes "shrunk in size or completely dried up" between 1950 and 2002 according to a study published in the Journal of Geophysical Research--Biogeosciences. The study says that during this period, "Alaska has experienced a warming climate with longer growing seasons, increased thawing of permafrost, and greater water loss due to evaporation from open water and transpiration from vegetation; yet there has been no substantial change in precipitation."
Extinction may be linked to Earth's tilt and orbital variations
(10/12/2006) A new study suggests that variations in Earth's orbit and tilt may be linked to extinctions of mammal species. Examining the fossilized teeth of rodents over a 22 million year period, researchers lead by Jan van Dam of Utrecht University in the Netherlands found that the disappearance of mammal species -- which survive an average of 2.5 million years before going exinct -- cluster around specific cycles at one million and 2.4 million years. The one million year cycle correponds to wobbles in Earth's orbit, while the 970,000-year cycle is tied to shifts of the Earth on its axis. The cycles are assocation with lower temperatures and changes in precipitation.
Massive coral bleaching in Madagascar
(10/06/2006) A new survey of reefs along Madagascar's southwestern coast found massive damage from coral bleaching, including some reefs that lost up to 99 percent of their coral cover. But the survey team, led by the conservation groups Blue Ventures and the Wildlife conservation Society (WCS) and funded by conservation International (CI), also found some signs of hope. Scientists discovered several small reefs with corals that appeared to be resilient to rising sea temperatures and could ultimately be used to reseed damaged reefs. These resilient reefs may also provide valuable information about how to protect corals from future damage.
Global warming threatens western U.S.
(10/06/2006) Global warming will cause drastic changes -- including reduction in snowpack, worsening droughts, increases in wildfire and invasive species, and loss of regional biodiversity -- in the American West if greenhouse gas emissions are not curtailed according to a new report from the National Wildlife Federation.

Global warming: Earth's temperature near highest level in a million years
(09/25/2006) Earth may nearing its warmest level in the last million years according to a paper published by NASA scientists in the Proceedings of the National Academy of Sciences. James Hansen of NASA's Goddard Institute for Space Studies in New York City and colleagues report that "Earth is now reaching and passing through the warmest levels in the current interglacial period" and that climate change is causing plant and animal species to migrate towards the north and south poles.
Dinosaurs survived rapid climate change
(09/23/2006) New research suggests the existence of periods of dramatic climate change during the Mesozoic Era, a time when dinosaurs ruled the Earth. The research, published in the September issue of Geology, presents evidence that ocean surface temperatures varied as much as 6 degrees Celsius (about 11 degrees Fahrenheit) during the Aptian Epoch of the Cretaceous Period 120 million years ago according to scientists from Indiana University Bloomington and the Royal Netherlands Institute for Sea Research who examined ancient rocks from the bottom of the Pacific Ocean. The results challenge the idea that the period was characterized by a stable, hot and humid climate.
Virgin's Branson commits $3 billion to fight global warming
(09/21/2006) According to BBC News, Sir Richard Branson will commit all profits from his travel firms, including airline Virgin Atlantic and Virgin Trains, over the next tend years to fight global warming.

Greenland's ice continues to melt
(09/20/2006) Data gathered by a pair of NASA satellites orbiting Earth show Greenland continued to lose ice mass at a significant rate through April 2006, and that the rate of loss is accelerating, according to a new University of Colorado at Boulder study.
Tree rings could settle global warming hurricane debate
(09/20/2006) Scientists have shown that ancient tree rings could help settle the debate as to whether hurricanes are strengthening in intensity due to global warming. By measuring different isotopes of oxygen present in the rings, Professors Claudia Mora and Henri Grissino-Mayer of the University of Tennessee have identified periods when hurricanes hit areas of the Southeastern United States up to 500 years ago. The research could help create a record of hurricanes that would help researchers understand hurricane frequency and intensity. Currently reliable history for hurricanes only dates back a generation or so. Prior to that, the official hurricane records kept by the National Oceanic and Atmospheric Administration's Atlantic basin hurricane database (HURDAT) are controversial at best since storm data from more than 20 years ago is not nearly as accurate as current hurricane data due to improvements in tracking technology. The lack of a credible baseline makes it nearly impossible to accurately compare storm frequency and strength over the period.
Arctic ice hole larger than Britain forms, shocks scientists
(09/20/2006) European Space Agency satellite images acquired from 23 to 25 August 2006 have shown for the first time dramatic openings larger than the size of the British Isles in the Arctic's perennial sea ice pack north of Svalbard, and extending into the Russian Arctic all the way to the North Pole. The agency says the findings are shocking to scientists. 'If this anomaly trend continues, the North-East Passage or 'Northern Sea Route' between Europe and Asia will be open over longer intervals of time, and it is conceivable we might see attempts at sailing around the world directly across the summer Arctic Ocean within the next 10-20 years,' said Mark Drinkwater, a scientist with ESA.
Climate Change Threatens Lemurs
(09/18/2006) Tropical rainforests are among the most stable environments on Earth, but they are still no match for global climate change. Dr. Patricia Wright, the widely admired primatologist and Professor of Anthropology at Stony Brook University, finds that climate change could mean the difference between survival and extinction for endangered lemurs.
One year later: Hurricane Katrina in review
(08/28/2006) While hurricane Katrina was the most devastating, causing 1833 fatalities and over $81 billion in damage, it was not the strongest storm of the year -- both Hurricane Rita and Hurricane Wilma were more powerful. Katrina, which at one point in the Gulf of Mexico was a Category 5 hurricane, was only a Category 3 hurricane when it made landfall near New Orleans on August 29, 2005. Nevertheless, the damage was extensive.
Climate change causing early spring
(08/25/2006) Spring is arriving earlier across Europe than it did 30 years ago according to new research published in the journal Global Change Biology. Scientists from 17 nations examined 125,000 studies involving 561 species and found that spring is beginning on average six to eight days earlier than it did 30 years ago. The researchers said that in countries where rapid increases in temperature have occurred, that figure is almost doubled.
Climate change caused dramatic changes in Antarctica 14 million years ago
(08/25/2006) Climate change 14 million years ago produced catastrophic drainage of subglacial lakes in Antarctica causing dramatic changes in the continent's landscape according to new research.
Why some Himalayan glacies aren't melting due to climate change
(08/25/2006) New research into climate change in the Western Himalaya and the surrounding Karakoram and Hindu Kush mountains could explain why many glaciers there are growing and not melting. The findings suggest this area, known as the Upper Indus Basin, could be reacting differently to global warming, the phenomenon blamed for causing glaciers in the Eastern Himalaya, Nepal and India, to melt and shrink.
North Atlantic Ocean freshening could weaken Gulf Stream
(08/24/2006) A new analysis of 50 years of changes in freshwater inputs to the Arctic Ocean and North Atlantic may help shed light on what's behind the recently observed freshening of the North Atlantic Ocean. In a report, published in the August 25, 2006 issue of the journal, Science, MBL (Marine Biological Laboratory) senior scientist Bruce J. Peterson and his colleagues describe a first-of-its-kind effort to create a big-picture view of hydrologic trends in the Arctic. Their analysis reveals that freshwater increases from Arctic Ocean sources appear to be highly linked to a fresher North Atlantic.
Americans believe hot weather, hurricanes linked to global warming
(08/23/2006) As first anniversary of Hurricane Katrina nears, a just-released Zogby poll shows that not only are Americans more convinced global warming is happening, they are also linking recent intense weather events like Hurricane Katrina and this summer's heat wave and droughts to global warming.
New potential fuel source carries global warming risk
(08/22/2006) Scientists supported by the Integrated Ocean Drilling Program, an international marine research program that explores sea floor sediments and rocks, announced that they found deposits of methane gas hydrates at considerably less depth than expected. The discovery, published in the August. 15, 2006 edition of EOS may have implications for future energy use as well as climate change.
Forest fires causing mercury pollution in North America
(08/21/2006) Increasing numbers of wildfires due to climate change could worsen mercury pollution in North America according to a new study from researchers at Michigan State University, the U.S. Geological Survey, the National Center for Atmospheric Research, and the Canadian Forest Service. Wildfires are releasing mercury long ago sequesterd in Northern wetlands.

Coal to oil conversion gaining interest in China, U.S.
(08/17/2006) High oil prices are spawning greater interest in technologies that convert coal into liquid fuel, according to an article published yesterday in The Wall Street Journal, but the shift could have a significant impact on the environment. Heightened tensions in the Middle East combined with booming demand and political instability in other regions have put a premium on crude oil and forced China and the United States -- the world's largest energy gluttons -- to look towards secure sources of fuel. Both countries are coal-rich but petroleum-poor. The Wall Street Journal says that China and the United States are actively developing coal-to-oil technology.
Climate change, not hunters, killed ancient Australia's giant kangaroos
(08/16/2006) Scientists at the University of Melbourne and La Trobe University have found strong evidence for the cause of the extinction of Australia's giant marsupials some 50,000 years ago. Cold, arid climates of the last ice age have been identified as a likely cause, casting doubt on the alternative hypothesis which blames human hunters.
Climate change has eroded Alps
(08/15/2006) The Alps, the iconic rugged mountains that cover parts of seven European nations, might have reached their zenith millions of years ago, some scientists believe, and now are a mere shadow of their former selves. New research offers an explanation - climate change.
More carbon dioxide may help some trees weather ice storms
(08/15/2006) The increased levels of carbon dioxide in the atmosphere predicted for later this century may reduce the damage that future ice storms will cause to commercially important loblolly pine trees, according to a new study.
Most of world's forests could be gone by 2100
(08/15/2006) New research claims that more than half the world's largest forests will be lost if global temperatures rise by an average of 3 degrees or more by the end of the century.The study, published in the current Proceedings of the National Academy of Sciences, says that a warmer climate also increases the risk of extreme floods, forest fires and droughts.
Hurricane intensity linked to global warming
(08/15/2006) A new study says climate change is affecting the intensity of Atlantic hurricanes and that hurricane damage will likely worsen in coming years due to increasing ocean temperatures. Unlike recent studies that have linked higher sea temperatures to an increase in the number of hurricanes, the new research shows a direct relationship between climate change and hurricane intensity.
Report Warns of Coastal Flooding and Rising Sea Levels in California
(08/14/2006) The California Climate Action Team has released a summary report of 17 scientific studies examining the potential impacts of climate change on California.

The presentation was held at Scripps Institution of Oceanography at UC San Diego.
Past climate change caused dramatic shift in humidity, precipitation levels, temperature, and ocean water salinity
(08/11/2006) Scientists have uncovered new evidence of dramatic changes in humidity, precipitation levels, temperature, and ocean water salinity during a past episode of global warming. Analyzing plant fossils collected in the Arctic, a team of researchers led by Mark Pagani, professor of geology and geophysics at Yale University, found that water and atmospheric water vapor are a major indicator of the greenhouse changes.
Snow in Antarctic not falling to counter sea level rise
(08/10/2006) The most precise record of Antarctic snowfall ever generated shows there has been no real increase in precipitation over the southernmost continent in the past half-century, even though most computer models assessing global climate change call for an increase in Antarctic precipitation as atmospheric temperatures rise.
Greenland's ice melting rapidly
(08/10/2006) A new analysis of data from twin satellites has revealed that the melting of Greenland's ice sheet has increased dramatically in the past few years, with much of the loss occurring primarily along one shoreline potentially affecting weather in Western Europe.
