MERCED, Calif. — The prolonged, extensive emission of greenhouse gases over the next several decades could have significant impacts on ocean life, according to a study by UC Merced marine biologist Michael Beman.
Increases in carbon dioxide e…
ANCHORAGE, Alaska — Sea-ice habitats essential to polar bears would likely respond positively should more curbs be placed on global greenhouse gas emissions, according to a new modeling study published today in the journal, Nature.
The study,…
Climate change is causing wildfires to burn more fiercely, pumping more greenhouse gases into the atmosphere than previously thought, according to a new study to be published in Nature Geosciences this week.
This is the first study to reveal t…
Current state-of-the-art global climate models predict substantial warming in response to increases in greenhouse gases such as carbon dioxide. The models, though, disagree widely in the magnitude of the warming we can expect. The disagreement a…
The United States and many other heavily populated countries face a growing threat of severe and prolonged drought in coming decades, according to results of a new study by National Center for Atmospheric Research (NCAR) scientist Aiguo Dai.

NEW YORK — Water vapor and clouds are the major contributors to Earth’s greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet’s temperature ultimately depends on the atmospheric level of carbon dioxide.
The s…
Des Moines, Iowa USA: World renowned scientists speaking at the World Food Prize Borlaug Dialogue have called for a radical transformation in the agriculture sector to cope with climate change, food security and to transition towards sustainability.

The Arctic sea ice cover appears to have reached its minimum extent for the year, the third-lowest recorded since satellites began measuring sea ice extent in 1979, according to the University of Colorado at Boulder’s National Snow and Ice Data C…
Although overall mortality from cancer is decreasing in the European Union, its incidence increased by almost 20%, from 2.1 million new cases in 2002 to 2.5 million in 2008, says a special issue [1] of the European Journal of Cancer (the official jo…
For the first time, scientists have incorporated multiple human and natural factors into a climate projection model. They predict that increased carbon dioxide in the atmosphere, due to changes in the carbon cycle, combined with a decrease in human-produced sulphates, may cause accelerated global warming during the 21st century, as compared with simulations without these feedback effects.
Even with aggressive research, the hydrogen fuel-cell vehicle will not be better than the diesel hybrid (a vehicle powered by a conventional engine supplemented by an electric motor) in terms of total energy use and greenhouse gas emissions by 2020, says a study recently released by MIT’s Laboratory for Energy and the Environment (LFEE). And while hybrid vehicles are already appearing on the roads, adoption of the hydrogen-based vehicle will require major infrastructure changes to make compressed hydrogen available. If we need to curb greenhouse gases within the next 20 years, improving mainstream gasoline and diesel engines and transmissions and expanding the use of hybrids is the way to go.
Energy Secretary Spencer Abraham and Under Secretary of State for Global Affairs Paula Dobriansky will be joined by representatives from several invited countries to announce plans for an international forum to advance carbon and storage technologies. In addition, Secretary Abraham will announce a government-sponsored, public-private partnership to create the world’s first pollution-free, fossil fuel fired power plant. The announcements follow a briefing to the President by Secretary Abraham, Secretary of State Colin Powell and Environmental Protection Agency Administrator Christine Todd Whitman.
