A survivor in Greenland: A novel bacterial species is found trapped in 120,000-year-old ice (6/7/2008)

Scientists have discovered a new ultra-small species of bacteria that has survived for more than 120,000 years within the ice of a Greenland glacier at a depth of nearly two miles ...> Full Article

Studies confirm greenhouse mechanisms even further into past (5/17/2008)

The newest analysis of trace gases trapped in Antarctic ice cores now provide a reasonable view of greenhouse gas concentrations as much as 800,000 years into the past, and are further confirming the link between greenhouse gas levels and global warming ...> Full Article

Ice cores reveal fluctuations in the Earth's greenhouse gases (5/16/2008)

Ice cores from Antarctica show both the lowest atmospheric content of CO2 (carbon dioxide) and fast changes in the content of CH4 (methane) measured over the past 800,000 years. ...> Full Article

Prestigious science prize awarded for 800,000 year old ice core (3/17/2008)

Ice core scientists from the British Antarctic Survey (BAS) are joint winners of a major European science prize. The European Project for Ice Coring in Antarctica (EPICA) - which retrieved two deep ice cores that have revealed how Earth's climate behaved over the last 800,000 years - is one of three projects to be awarded the 2007 Descartes Prize for excellence in collaborative research. Three winning trans-national research teams share this year's Descartes Prize of 1.36 million Euros. The prize is awarded annually to teams which have achieved outstanding scientific or technological results through collaborative research in any field of science. ...> Full Article

More evidence of changing weather patterns around the Antarctic Peninsula - a region where climate has changed rapidly over the last 50 years - is published this month in Geophysical Research Letters (online). ...> Full Article

New Antarctic Ice Core to Provide Clearest Climate Record Yet (1/23/2008)

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. ...> Full Article
