Natural Gas Formation By Bacteria Linked To Climate Change And Renewable Energy (1/27/2008)

Natural gas reservoirs in Michigan's Antrim Shale are providing new information about global warming and the Earth's climate history, according to a recent study by Steven Petsch, a geoscientist at the University of Massachusetts Amherst. The study is also good news for energy companies hoping to make natural gas a renewable resource. ...> Full Article



Arctic Impact Crater Lake Reveals Interglacial Cycles in Sediments (12/13/2007)

Arctic Impact Crater Lake Reveals Interglacial Cycles in SedimentsResearchers have taken cores from the sediments of a Canadian Arctic lake and found an interglacial record indicating two ice-free periods that could pre-date the Holocene Epoch. ...> Full Article


'Noah's flood' kick-started European farming (11/20/2007)

The flood believed to be behind the Noah's Ark myth kick-started European agriculture, according to new research by the Universities of Exeter and Wollongong, Australia. Published in the journal Quaternary Science Reviews, the research paper assesses the impact of the collapse of the North American (Laurentide) Ice Sheet, 8000 years ago. The results indicate a catastrophic rise in global sea level led to the flooding of the Black Sea and drove dramatic social change across Europe. The research team argues that, in the face of rising sea levels driven by contemporary climate change, we can learn important lessons from the past. ...> Full Article

Carbon Dioxide Did Not End The Last Ice Age, Study Says (10/9/2007)

Carbon Dioxide Did Not End The Last Ice Age, Study SaysCarbon dioxide did not cause the end of the last ice age, a new study in Science suggests, contrary to past inferences from ice core records. ...> Full Article


Clues to End of the Last Ice Age (9/29/2007)

Researcher shows that deep-sea temperatures rose 1,300 years before the buildup of atmospheric carbon dioxide, ruling out CO2 as driver of the last ice age's meltdown. ...> Full Article


Next Ice Age delayed by rising CO2 levels (8/31/2007)

Future ice ages may be delayed by up to half a million years by our burning of fossil fuels. That is the implication of recent work by Dr Toby Tyrrell of the University of Southampton's School of Ocean and Earth Science at the National Oceanography Centre, Southampton. ...> Full Article
