Research finds that Earth's climate is approaching 'dangerous' point
NASA and Columbia University Earth Institute research finds that human-made greenhouse gases have brought the Earth's climate close to critical tipping points, with potentially dangerous consequences for the planet.   view more (2007-06-01)

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)

Antarctic ice loss speeds up, nearly matches Greenland loss
Ice loss in Antarctica increased by 75 percent in the last 10 years due to a speed-up in the flow of its glaciers and is now nearly as great as that observed in Greenland, according to a new, comprehensive study by UC Irvine and NASA scientists.   view more (2008-01-24)

Scientist-evangelical Alaska expedition
The historic collaboration between leading scientists and Evangelicals to protect the environment, spearheaded by the Center for Health and the Global Environment at Harvard Medical School (HMS) and the National Association of Evangelicals (NAE) continues this week with a trip to Alaska.   view more (2007-08-30)

Radar altimetry confirms global warming is affecting polar glaciers
Scientists have confirmed that climate warming is changing how much water remains locked in the Antarctic and Greenland ice sheets, according to an article published in the Journal of Glaciology.   view more (2006-03-20)

Southampton scientists set sail for the Arctic on historic voyage to investigate impact of global warming
Dr Val Byfield and Sarah Fletcher from Southampton Oceanography Centre will be setting sail from Tromso in Norway next week on their way to the Arctic on board a 93-year-old sailing vessel, as part of a unique project to investigate the impact of global warming.   view more (2003-05-23)

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...

New research provides insight into ice sheet behavior
A new study published this week takes scientists a step further in their quest to understand how Antarctica's vast glaciers will contribute to future sea-level rise.   view more (2009-07-21)

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)

What is really happening to the Greenland icecap?
The Greenland ice cap has been a focal point of recent climate change research because it is much more exposed to immediate global warming than the larger Antarctic ice sheet.   view more (2008-11-03)

NASA provides new perspectives on the earth's changing ice sheets
It's widely documented that climate change is causing the Greenland and Antarctic ice sheets to shrink. Air temperatures in many parts of the polar regions have increased and waters that surround parts of the ice sheets have warmed up.   view more (2006-12-12)

Alaska glacier speed-up tied to internal plumbing issues, says CU-Boulder study
A University of Colorado at Boulder study indicates meltwater periodically overwhelms the interior drainpipes of Alaska's Kennicott Glacier and causes it to lurch forward, similar to processes that may help explain the acceleration of glaciers observed recently on the Greenland ice sheet that are contributing to global sea rise.   view more (2008-01-16)

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)

European lead in reading past climates from ice cores
Climate change is a reality today, but how can we find out about the future dangers it poses" What we really need is a full record of the Earth's climate for several hundred thousand years, complete with samples of air from different epochs that can be taken to the lab for analysis.   view more (2007-10-12)

The Arctic offers more evidence of human influences on climate change
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.    view more (2009-09-04)

Tipping elements in the Earth's climate system
Anthropogenic forcing could push the Earth's climate system past critical thresholds, so that important components may "tip" into qualitatively different modes of operation.   view more (2008-02-05)

How chilly was the last ice age?
Polar oceans permanently covered with ice, temperatures ten to twelve degrees Celsius lower than today in the North Atlantic region, tropical oceans on the other hand only two degrees Celsius below modern values: Until quite recently these were the general ideas climate researchers had about the climax of the last ice age 20.000 years ago. Now... view more... (1999-05-03)

Departure to cold water corals and other 'hot spots'
The research vessel, Polarstern leaves Bremerhaven for its 22nd Arctic expedition with a new shine, to begin its first work in the International polar year.   view more (2007-05-25)

Exploration of lake hidden beneath Antarctica's ice sheet begins
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.   view more (2008-01-16)

Scientists Detect Thinning West Antarctic Ice.
A major glacial formation in Antarctica is shrinking, a report in SCIENCE will reveal today. But questions still remain about the speed at which ice sheet thinning is taking place. Scientists at University College London (UCL) and the British Antarctic Survey have used satellite data to show that the interior of the West Antarctic Ice Sheet (WAIS)... view more... (2001-01-29)
