After enduring months on the coldest, driest, and windiest continent on Earth, researchers today closed out the inaugural season on an unprecedented, multi-year effort to retrieve the most detailed record of greenhouse gases in Earth’s atmosphere over the last 100,000 years.

Climate scientists are collaborating with experts in economic theory to improve their forecasting models and assess more accurately the impact of rising atmospheric carbon dioxide levels. Although there is broad consensus that there will be a significant rise in average global temperature, there is great uncertainty over the extent of the change, and the implications for different regions.

Anaerobic microbes in the Earth's oceans consume 90 percent of the methane produced by methane hydrates – methane trapped in ice – preventing large amounts of methane from reaching the atmosphere.

Drenching Rain in the Southeast Today; Moving up the East Coast on Thursday.

California is being hit be a series of storms and it’s being called the worst weather the California has had in years. The storm in California may bring hurricane like winds, mudslides and possible snow. San Francisco Bay Area weather is expected to get nasty today with coastal flooding and high winds.

The average annual temperature rose by 1.5 degrees Celsius last year according to latest statistics. Across the globe, 2007 is predicted to be the fifth warmest year on record since measuring began in 1880.

Sulfur dioxide (SO2) may have played a key role in the climate and geochemistry of early Mars, geoscientists at Harvard University and the Massachusetts Institute of Technology suggest in the Dec. 21 issue of the journal Science.

Atleast nine people have succumbed to the snowstorm that blustered through the Midwest region of the Unites States and left thousands of homes and businesses without electricity.

A major winter storm has moved from the U. S. midwest to the northeastern part of the country.

A US-European standoff headed toward a compromise solution late on Friday at the UN climate conference, breaking a deadlock over how ambitious the goal should be in negotiating future cutbacks in global-warming gases, the UN climate chief said.

Record-breaking amounts of ice-free water have deprived the Arctic of more of its natural "sunscreen" than ever in recent summers. The effect is so pronounced that sea surface temperatures rose to 5 C above average in one place this year, a high never before observed, says the oceanographer who has compiled the first-ever look at average sea surface temperatures for the region.

Levels of a climate cooling gas will change as carbon dioxide increases, affecting food webs along the way, said Dr Michael Steinke at a Science Media Centre press briefing today.
