Human activity destroys species that the Ice Age could not
Forest clearance and animal overgrazing in the last 5,000 years have destroyed important tree species that had survived even the Ice Age. Dr Mick Frogley, Lecturer in Physical Geography at the University of Sussex, is one of a British research team exploring a site near Lake Ioannina in the Pindus Mountains of northwestern Greece. "Given the... view more... (2002-09-20)
Arctic, antarctic melting may raise sea levels faster than expected
Ice sheets across both the Arctic and Antarctic could melt more quickly than expected this century, according to two studies that blend computer modeling with paleoclimate records. view more (2006-03-24)
A bumpy shift from ice house to greenhouse
The transition from an ice age to an ice-free planet 300 million years ago was highly unstable, marked by dips and rises in carbon dioxide, extreme swings in climate and drastic effects on tropical vegetation, according to a study published in the journal Science Jan. 5. view more (2007-01-05)
Dust may settle unanswered questions on Antarctica
Dust trapped deep in Antarctic ice sheets is helping scientists unravel details of past climate change. view more (2009-03-30)
Unravelling the 'inconvenient truth' of glacier movement
Predicting climate change depends on many factors not properly included in current forecasting models, such as how the major polar ice caps will move in the event of melting around their edges. view more (2008-06-30)
Earth's heat adds to climate change to melt Greenland ice
Scientists have discovered what they think may be another reason why Greenland's ice is melting: a thin spot in Earth's crust is enabling underground magma to heat the ice. They have found at least one "hotspot" in the northeast corner of Greenland -- just below a site where an ice stream was recently discovered. view more (2007-12-13)
UCSB scientists propose Antarctic location for 'missing' ice sheet
New research by scientists at UC Santa Barbara indicates a possible Antarctic location for ice that seemed to be missing at a key point in climate history 34 million years ago. view more (2009-08-26)
Remnants of ice age linger in gravity
Researchers have uncovered a large area of low but increasing gravity over North America - the lingering effect of the last ice age when sheets of ice sometimes three kilometres thick covered nearly all of Canada and the northeastern U.S. view more (2007-05-11)
Methane Release Could Cause Abrupt, Far-Reaching Climate Change
An abrupt release of methane, a powerful greenhouse gas, from ice sheets that extended to Earth's low latitudes some 635 million years ago caused a dramatic shift in climate, scientists funded by the National Science Foundation (NSF) report in this week's issue of the journal Nature. view more (2008-05-29)
In the Cornucopia of the European Project of Ice Coring in Antarctica: the oldest Antarctic ice core
On Tuesday 21th of December 2004 a European team involved in Epica (European Project for Ice Coring in Antarctica) reached the drilling depth of 3270.2, which is five meters above the bedrock at Dome C, on the central plateau of the east Antarctic ice sheet. The ice is melting at the bedrock and it has been decided to stop at this depth to avoid... view more... (2005-01-13)
Melting of the Greenland ice cap may have consequences for climatic change
According to two international-research studies on the last ice age, studies with the participation of Dr Rainer Zahn, research professor in the ICREA at the UAB Institute of Environmental Science and Technology (ICTA), before the great ice sheets of the Arctic Ocean began to melt, early sporadic episodes of melting of the old ice sheet which... view more...

Ice Sheets Can Retreat
Modern glaciers, such as those making up the Greenland and Antarctic ice sheets, are capable of undergoing periods of rapid shrinkage or retreat, according to new findings by paleoclimatologists at the University at Buffalo. view more (2009-06-22)
ODP scientists say no large Northern Hemisphere ice sheets 41 million years ago
New research to test global ice volume approximately 41.6 million years ago shows that ice caps at this time, if they existed at all, would have been small and easily accommodated on Antarctica. view more (2007-08-23)
Radar opens new window into the ice for Antarctic scientists
Scientists are getting their first glimpse into the inner secrets of an ice shelf, thanks to the innovative application of a new radar technique developed by British Antarctic Survey (BAS). view more (2006-10-17)
Deep sea algae connect ancient climate, carbon dioxide and vegetation
Assistant Professor Mark Pagani in the Department of Geology and Geophysics at Yale and his colleagues mapped the first detailed history of atmospheric carbon dioxide between 45-25 million years ago based on stable isotopes of carbon in a National Science Foundation study reported in Science Express. view more (2005-06-23)
Boston university researchers develop new model of ice volume change based on Earth's orbit
Through dated geological records scientists have known for decades that variations in the Earth's orbit around the sun — subtle changes in the distance between the two — control ice ages. view more (2006-06-23)
Ice Ages and rivers may have affected gorilla diversification
Geography and historical climate change may have both played a major role in gorilla evolutionary diversification, according to a new genetic study by Cardiff University and the University of New Orleans. view more (2007-12-11)
New CO2 data helps unlock the secrets of Antarctic formation
The link between declining CO2 levels in the earth's atmosphere and the formation of the Antarctic ice caps some 34 million years ago has been confirmed for the first time in a major research study. view more (2009-09-14)
Medieval diaries aid scientists ascertain increase in hot spots due to global warming
The study finds that the number of 'hot spots' has increased dramatically in the Northern Hemisphere in the last century compared to the past 1200 years ¨C adding to the growing evidence of wide-scale global warming. view more (2006-02-10)
Overall Antarctic snowfall hasn't changed in 50 years
The most precise record of Antarctic snowfall ever generated shows there has been no real increase in precipitation over the southernmost continent in the past half-century, even though most computer models assessing global climate change call for an increase in Antarctic precipitation as atmospheric temperatures rise. view more (2006-08-11)
