A new NASA-led study shows human-caused climate change has made an impact on a wide range of Earth's natural systems, including permafrost thawing, plants blooming earlier across Europe, and lakes declining in productivity in Africa.
Rationing oil cannot address the larger issue
Some day, fuel cells may power your car and exhaust only water and perhaps carbon dioxide. More efficient and cleaner than an internal combustion engine, their emissions will be much lower. They may also run your home without the energy loss of power lines, or even power your laptop or cell phone. But not today or even tomorrow.
Data laboriously extracted from an Antarctic ice core provide an unprecedented view of temperature, and levels of atmospheric carbon dioxide and methane, over the past 800,000 years of Earth's history.
Reflecting on how far we have come scientifically since isolating HIV in 1983, Anthony S. Fauci urges a renewed commitment to the far greater challenges ahead, especially that of vaccine development.
Remarks Come In The Wake Of US Prez Blaming India For Global Food Crisis One way to beat the worldwide grain shortage is for meateaters to turn vegetarian, and the movement should start with US president George Bush, the Indian affiliate of animal rights organization Peta has said.

China mobilized 30,000 additional soldiers to the earthquake-shattered expanses of the nation's southwestern regions on Wednesday
Climatologists have called for massive investment in computer and research resources to help revolutionize modelling capabilities. The eventual aim is to provide probabilistic climate predictions that are as useful, and usable, as weather forecasts. At the end of a four-day summit held last week at the European Centre for Medium-Range Weather Forecasts in Reading, UK, the scientists made the case for a climate-prediction project on the scale of the Human Genome Project.
After the squall lashed the Capital on Wednesday, Met officials attributed the sudden change in weather to a low pressure disturbances in the neighbouring region.
Air travel shows no sign of losing its allure but its environmental impact is not going to go away. Katharine Sanderson looks at some of the ways that scientists and engineers hope to reduce the carbon wing-print of aircraft.
