Scientists to track impact of Asian dust and pollution on clouds, climate change
Scientists using one of the nation's newest and most capable research aircraft are launching a far-reaching field project this month to study plumes of airborne dust and pollutants that originate in Asia and journey to North America. view more (2007-04-19)
Denver to Barcelona: Global cities and greenhouse gas emissions
Denver released the largest amount of greenhouse gases (GHG) and Barcelona the smallest amount in a new study documenting how differences in climate, population density and other factors affect GHG emissions in global cities. view more (2009-09-24)
Global Warming Affects World's Largest Freshwater Lake
Russian and American scientists have discovered that the rising temperature of the world's largest lake, located in frigid Siberia, shows that this region is responding strongly to global warming. view more (2008-05-01)
At Least Part of Climate Change is Man-Made
Humanity does seem to have been a major contributor to global warming after all. This has been demonstrated by new simulations carried out at the University of Bonn. The Bonn meteorologists used about 30 different models to investigate how the Earth's average annual temperature would have developed with and without the influence of climate gases.... view more...

Methane Release Could Cause Abrupt, Far-Reaching Climate Change
An abrupt release of methane, a powerful greenhouse gas, from ice sheets that extended to Earth's low latitudes some 635 million years ago caused a dramatic shift in climate, scientists funded by the National Science Foundation (NSF) report in this week's issue of the journal Nature. view more (2008-05-29)
Rising CO2 signals wetter storms for Northern Hemisphere, says CU-Boulder study
While two new studies by researchers at the University of Colorado at Boulder's Cooperative Institute for Research in Environmental Sciences predict wetter storms for the Arctic and for the Northern Hemisphere because of global warming, whether or not this means more net precipitation depends on the latitude. view more (2007-12-12)
Dust threatens Kyoto protocol
On the eve of the Earth Summit in Johannesburg, scientists at UCL have detected a flaw in the Kyoto protocol`s global plans to reduce the impact of global warming, all because of something as simple as atmospheric dust. Dr Mark Maslin of UCL`s Environmental Change Research Centre explains: "Dust is vital to the health of the planet. This is not... view more... (2002-08-07)
Global Warming: Cuts in Greenhouse Gas Emissions Would Save Arctic Ice, Reduce Sea Level Rise
The threat of global warming can still be greatly diminished if nations cut emissions of heat-trapping greenhouse gases by 70 percent this century, according to a new analysis. view more (2009-04-15)
Global warming may have damaged coral reefs forever
Global warming has had a more devastating effect on some of the world's finest coral reefs than previously assumed, suggests the first report to show the long-term impact of sea temperature rise on reef coral and fish communities. view more (2006-05-16)
Global change conference sets the scene for next round of Kyoto Protocol talks
Throughout the world, scientists are seeing clear signs that the Earth is rapidly changing. Tropical glaciers are melting fast and some will disappear within 15 years if current warming trends continue. Fifty percent of the land surface has been modified and more than half the world’s accessible freshwater is being used directly or... view more... (2001-04-10)
Major international study warns global warming is destroying coral reefs and calls for 'drastic actions'
If world leaders do not immediately engage in a race against time to save the Earth's coral reefs, these vital ecosystems will not survive the global warming and acidification predicted for later this century. That is the conclusion of a group of marine scientists from around the world in a major new study published in the journal Science on Dec.... view more... (2007-12-26)
Ice age imprint found on cod DNA
An international team of researchers, led by the University of Sheffield, has demonstrated how Atlantic cod responded to past natural climate extremes. The new research could help in determining cods vulnerability to future global warming. view more (2007-11-14)
Warmer seas linked to strengthening hurricanes: FSU study fuels global warming debate
The theory that global warming may be contributing to stronger hurricanes in the Atlantic over the past 30 years is bolstered by a new study led by a Florida State University researcher. The study will be published in the Sept. 4 edition of the journal Nature. view more (2008-09-04)
Climate variability impacts the deep sea
Deep-sea ecosystems occupying 60% of the Earth's surface could be vulnerable to the effects of global warming warn scientists writing in the Proceedings of the National Academy of Sciences. view more (2009-11-03)
Radar altimetry confirms global warming is affecting polar glaciers
Scientists have confirmed that climate warming is changing how much water remains locked in the Antarctic and Greenland ice sheets, according to an article published in the Journal of Glaciology. view more (2006-03-20)
Global 'sunscreen' has likely thinned, report NASA scientists
A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases - sunlight blocked by dust, pollution and other aerosol particles - appears to have lost ground. view more (2007-03-19)
Lands surface change on Alaska tundra creating longer, warmer summers in Arctic
A gradual lengthening of the snow-free season in Alaska's tundra, and a corresponding northward progression of the growth of shrubs and trees, may be creating a cycle of warmer and longer summers in the Alaskan Arctic. view more (2005-09-23)
Working with Inuit Community Is Part of Scientific Expedition
Research on global warming is drawing scientists in increasing numbers to the world's polar regions. But as scientists make more journeys northward, some of them find that their mission now extends beyond the ice or sediment samples they will bring back to their labs to analyze. view more (2007-05-17)
Global warming plus natural bacteria could release vast carbon deposits currently stored in Arctic soil
Increasing concentrations of carbon dioxide in the atmosphere will make global temperatures rise. By studying soil cores from the Arctic, scientists have discovered that this rise in temperature stimulates the growth of microorganisms that can break down long-term stores of carbon, releasing them into the atmosphere as carbon dioxide. This will... view more... (2005-05-05)
Earlier global warming produced a whole new form of life
Researchers from McGill University, along with colleagues from the California Institute of Technology, the Curie Institute in Paris, Princeton University and other institutions, have unearthed crystalline magnetic fossils of a previously unknown species of microorganism that lived at the boundary of the Paleocene and Eocene epochs, some 55 million... view more...
