Were short warm periods typical for transitions between interglacial and glacial epochs? (3/4/2010)

At the end of the last interglacial epoch, around 115,000 years ago, there were significant climate fluctuations. In Central and Eastern Europe, the slow transition from the Eemian Interglacial to the Weichselian Glacial was marked by a growing instability in vegetation trends with possibly at least two warming events. This is the finding of German and Russian climate researchers who have evaluated geochemical and pollen analyses of lake sediments in Saxony-Anhalt, Brandenburg and Russia. ...> Full Article

Digging deeper below Antarctica's Lake Vida (9/15/2009)

Two UIC geoscientists will lead an exploration of Antarctica's perpetually ice-covered Lake Vida, site of one of the most extreme environments on Earth for living organisms. The team will drill through the lake's ice cap, and take the first-ever samples of the underlying brine and sediment. ...> Full Article

Map characterizes active lakes below Antarctic ice (9/3/2009)

Lakes in Antarctica, concealed under miles of ice, require scientists to come up with creative ways to identify and analyze these hidden features. Now, researchers using space-based lasers on a NASA satellite have created the most comprehensive inventory of lakes that actively drain or fill under Antarctica's ice. They have revealed a continental plumbing system that is more dynamic than scientists thought. ...> Full Article

Great Basin's Bear Lake reveals records of past climate (3/23/2009)

The Geological Society of America presents a new Special Paper, Paleoenvironments of Bear Lake, Utah and Idaho, and Its Catchment. This volume is the culmination of more than a decade of coordinated investigations aimed at a holistic understanding of the long-lived Bear Lake, which is located 100 km northeast of Salt Lake City, along the course of the Bear River, the largest river in the Great Basin of the western United States. ...> Full Article

Current Major Flooding in U.S. a Sign of Things to Come (3/24/2008)

Major floods striking America's heartland in March offer a preview of the spring seasonal outlook, according to NOAA's National Weather Service. Several factors will contribute to above-average flood conditions, including record rainfall in some states and snow packs, which are melting and causing rivers and streams to crest over their banks. The week of March 15, more than 250 communities in a dozen states are experiencing flood conditions. ...> Full Article

Warming climate may cause arctic tundra to burn (3/8/2008)

Research from ancient sediment cores indicates that a warming climate could make the world's arctic tundra far more susceptible to fires than previously thought. The findings, published this week in the online journal, PLoS ONE, are important given the potential for tundra fires to release organic carbon - which could add significantly to the amount of greenhouse gases already blamed for global warming. ...> Full Article

Drained lake holds record of ancient Alaska (2/29/2008)

Not too long ago, a lake sprung a leak in the high country of the Wrangell-St. Elias Mountains. The lake drained away, as glacier-dammed lakes often do, but this lake was a bit different, and seems to be telling a story about a warmer Alaska. ...> Full Article

Do Hydroelectric Dams Pose A New Threat To Lake Victoria? (2/4/2008)

Two hydroelectricity dams appear to be threatening the health of Lake Victoria -- and of the people living along its shores who depend on the lake for food. A new studyš suggests that the dams' systematic overuse of water has decreased the lake level by at least two meters between 2000 and 2006 -- and that this drop was not influenced by weather. ...> Full Article

Exploration Of Lake Hidden Beneath Antarctica's Ice Sheet Begins (1/18/2008)

A four-man science team led by British Antarctic Survey's (BAS) Dr Andy Smith has begun exploring an ancient lake hidden deep beneath Antarctica's ice sheet. The lake -- the size of Lake Windermere (UK) -- could yield vital clues to life on Earth, climate change and future sea-level rise. ...> Full Article
