Australian and US scientists have discovered how changes in winds blowing on the Southern Ocean drive variations in the depth of the surface layer of sea water responsible for regulating exchanges of heat and carbon dioxide between the ocean and the atmosphere. The researchers' findings "“ published on-line today in Nature Geoscience "“ provide new insights into natural processes which have a major influence on the rate of climate change. The surface-mixed layer is a crucial...

A new study of Antarctica's past climate reveals that temperatures during the warm periods between ice ages may have been higher than previously thought A new study of Antarctica's past climate reveals that temperatures during the warm periods between ice ages (interglacials) may have been higher than previously thought. The latest analysis of ice core records suggests that Antarctic temperatures may have been up to 6°C warmer than the present day. The findings, reported this week by...

Remains On Downward Trend Despite a slight recovery in summer Arctic sea ice in 2009 from record-setting low years in 2007 and 2008, the sea ice extent remains significantly below previous years and remains on a trend leading toward ice-free Arctic summers, according to the University of Colorado at Boulder's National Snow and Ice Data Center. According to the CU-Boulder center, the 2009 minimum sea ice extent was the third lowest since satellite record-keeping began in 1979. The past five...

CU-Boulder's Snow and Ice Data Center analysis shows negative summertime ice trend continues 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 Center. While this year's September minimum extent was greater than each of the past two record-setting and near-record-setting low years, it is still...

U.S.-led scientists conducting an ecosystem study of arctic warming say they've determined the arctic, as we know it, might soon be a thing of the past. The international team, led by Penn State University Associate Professor Eric Post, carried out studies of the biological response to arctic warming during the fourth International Polar Year that ended in 2008 and documented a wide range of responses by plants, birds, animals, insects and humans living in the region. Post said his team...

A new study indicates that Arctic temperatures suddenly increased during the last 50 years of the period from 1 AD to the year 2000. Because this warming occurred abruptly during the 20th Century while atmospheric greenhouse gases were accumulating, these findings provide additional evidence that humans are influencing climate. Incorporating geologic records, biologic records and computer simulations, the study reconstructed Arctic summer temperatures at a resolution down to decades, and...

Arctic thawing is likely to result in worldwide consequences - from an increase in greenhouse gases and global weather pattern changes, according to a WWF report on Wednesday. The World Wildlife Fund released a new study, titled "Arctic Climate Feedbacks: Global Implications," Wednesday that found that Arctic ice is shrinking at a much quicker pace than previously expected. The thawing Arctic is likely to have far-reaching implications that will affect hundreds of millions of people, WWF...

Average ocean surface temperatures reached an all-time high in July, according to a new US agency report. The National Oceanic and Atmospheric Administration's National Climatic Data Center reported Thursday that the average global ocean temperature reached 62.6 degrees in July "“ replacing the previous high temperature record set in 1998. The combined average of global land and surface temperature during July ranked fifth in the overall warmest since records began in 1880, according to...

The National Science Foundation (NSF) made its first major award under the American Recovery and Reinvestment Act to construct the Alaska Region Research Vessel (ARRV). This investment will not only provide a technologically advanced tool for science but help preserve jobs and promote economic recovery. The three-year construction phase of the project will support 4,350 total jobs--750 directly at the shipyard and as many as 3,600 in the broader economy. NSF intends to ensure that the ARRV is...

Former Vice President Al Gore called for fast action to avert the potentially irreversible melting of the Earth's ice. Speaking at the first conference to exclusive discuss the planet's melting ice, the Nobel prize winning climate champion warned that the situation is worse than previous worst-case scenarios projected by experts just a few years ago. The Tromsoe, Norway, conference comes just months ahead of a U.N. climate summit set for December in Copenhagen. "This conference is a global...
