(09/27/2006) Scientists at the University of Alaska Fairbanks International Arctic Research Center say that warm water from the North Atlantic Ocean continues to surge into the Arctic Ocean potentially increasing ice melt in the region.
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.

(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 glaciers 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.

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.

(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. Today, officials discussed the report, the science and what the state is doing to take action on reducing heat-trapping gases that threaten to cause more frequent coastal floods, rising sea levels, beach erosion and disruptions to wetlands. 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.
Carbon dioxide-eating enzyme could fight global warming
(08/09/2006) A new technology could help fight climate change by letting carbon-dioxide enzymes do the work. According to Mark Wendman of the UK-based Inquirer a Canadian firm has licensed production rights to an enzyme that scrubs carbon dioxide from smokestacks and other concentrated sources. The byproducts from the CO2 scrubbing process are carbonate and hydrogen gas, which could serve as a fuel source.
Global Warming Threatens Pollination Timing
(08/09/2006) In addition to the more obvious effects of climate change, such as rising sea levels and increasing storm activity, there is the potential to dramatically alter ecological communities. Dr. David Inouye, director of University of Maryland's graduate program in Sustainable Development and conservation Biology, reports that global warming could disrupt the timing of pollination in alpine environments, with serious negative impacts to both plants and pollinators.
Carbon emissions could be buried in deep-sea sediments
(08/08/2006) Deep-sea sediments could provide a virtually unlimited and permanent reservoir for carbon dioxide, the gas that has been a primary driver of global climate change in recent decades, according to a team of scientists that includes a professor from MIT. The researchers estimate that seafloor sediments within U.S. territory are vast enough to store the nation's carbon dioxide (CO2) emissions for thousands of years to come.
Rising seas may be killing Florida palms
(08/08/2006) Palm trees on Florida's west coast appear to be dying more rapidly than in previous years because of sea level rise tied to global warming. University of Florida scientists who began monitoring a large coastal study area in North Florida in 1992 reported widespread deaths of palms and other trees in low-lying coastal areas in the past. But the latest survey of the waterfront area along the Gulf of Mexico reveals new and unsettling numbers: Of 88 large, mature palms that died at the rural Levy County site between 1992 and 2005, 66 percent, or 58, have died since 2000.
July was second-hottest month in U.S. history

Cellulosic ethanol fuels environmental concerns
(08/06/2006) In recent months, high fuel prices and national security concerns have sparked interest in biofuels. Cellulosic ethanol, which can be derived from virtually any plant matter including farm waste, looks particularly promising. The U.S. Department of Energy projects that cellulosic conversion technology could reduce the cost of producing ethanol by as much as 60 cents per gallon by 2015. Green groups see cellulosic ethanol as a carbon neutral energy source that could be used to fight the build up of atmospheric carbon dioxide responsible for global warming.
Shell chairman calls for clean coal technologies to fight global warming
(08/04/2006) In a talk given last week at the prestigious Royal Society in Britain, the outgoing chairman of Shell Oil said that cleaner-burning coal technologies are urgently needed to minimize greenhouse gas emissions from the ongoing use of fossil fuels in the coming decades.

Primate evolution linked to global warming says new study
(07/31/2006) New research suggests the ancient climate change fueled early primate evolution.
Arguing climate change to an energy executive
(07/25/2006) Earlier this month I had the opportunity to make a pitch to "Mike," a top executive of a major energy company, about climate change and green energy. Mike said he didn't believe humans are influencing climate or that green energy is a key factor in the future business of his firm, "EnergyCo." I tried to persuade him otherwise, not by focusing on the science of climate change but on economics and market opportunities. It's not that science isn't important--I just didn't want to get caught up in an argument about core beliefs, which is akin to arguing over religion.
Global Warming Threatens Australia's Tropical Biodiversity
(07/25/2006) Global climate change will pose serious challenges for wildlife populations around the world in the coming decades. The findings of Dr. Stephen Williams (Centre for Tropical Biodiversity and Climate Change, James Cook University) suggest that endemic wildlife populations in Australia's Wet Tropics World Heritage Area will be particularly vulnerable to the local warming trend.
Sun, not carbon dioxide, primary driver of ice ages says new theory
(07/24/2006) A new theory says that carbon dioxide is only a secondary driver of ice ages. In a paper published online in the journal Climate of the Past, William Ruddiman, an environmental scientist with the University of Virginia, argues that "carbon dioxide is a driver of ice sheets only at the relatively small 23,000-year cycle, but not at the much larger ice-volume cycles at 41,000 years and approximately 100,000 years" according to a news release from the university.
