Study links ecosystem changes in temperate lakes to climate warming
Unparalleled warming over the last few decades has triggered widespread ecosystem changes in many temperate North American and Western European lakes, say researchers at Queen's University and the Ontario Ministry of the Environment.   view more (2008-12-17)

UD researchers focus on building telescope at South Pole
It's 40 degrees F below zero (with the wind chill) at the South Pole today. Yet a research team from the University of Delaware is taking it all in stride.   view more (2008-12-10)

Cave's climate clues show ancient empires declined during dry spell
The decline of the Roman and Byzantine Empires in the Eastern Mediterranean more than 1,400 years ago may have been driven by unfavorable climate changes.   view more (2008-12-08)

Getting Warmer? Prehistoric Climate Can Help Forecast Future Changes
The first comprehensive reconstruction of an extreme warm period shows the sensitivity of the climate system to changes in carbon dioxide (CO2) levels as well as the strong influence of ocean temperatures, heat transport from equatorial regions, and greenhouse gases on Earth's temperature.    view more (2008-11-25)

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)

Scientists probe Antarctic glaciers for clues to past and future sea level
Scientists from the U.S., U.K. and Australia have teamed up to explore two of the last uncharted regions of Earth, the Aurora and Wilkes Subglacial Basins, immense ice-buried lowlands in Antarctica with a combined area the size of Mexico.   view more (2008-10-28)

ESA leads the way to map boreal forest
How best to map 'boreal' or northern forest with spaceborne radar is the focus of an ESA campaign currently underway in northern Sweden.   view more (2008-10-21)

Genes hold secret of survival of Antarctic 'antifreeze fish'
A genetic study of a fish that lives in the icy waters off Antarctica sheds light on the adaptations that enable it to survive in one of the harshest environments on the planet.   view more (2008-10-17)

U.S.-Led, International AGAP Team Poised to Probe One of Antarctica's Last Unexplored Places
A U.S.-led, multinational team of scientists from six nations will pierce the mysteries of one of the globe's last major unexplored places this month. Using sophisticated airborne radar and other Information Age tools and techniques, the scientists will virtually "peel away" more than... view more (2008-10-15)

2008 ozone hole larger than last year
The 2008 ozone hole - a thinning in the ozone layer over Antarctica - is larger both in size and ozone loss than 2007 but is not as large as 2006.   view more (2008-10-08)

Gas from the past gives scientists new insights into climate and the oceans
In recent years, public discussion of climate change has included concerns that increased levels of carbon dioxide will contribute to global warming, which in turn may change the circulation in the earth's oceans, with potentially disastrous consequences.   view more (2008-10-06)

Advice from research: market visiting rights to Antarctica
Tourism on Antarctica is increasing and that can form a threat for the vulnerable South Pole area. Research from Maastricht University provides a possible solution: market the visitor rights to the highest bidder.   view more (2008-09-29)

Curbing coal emissions alone might avert climate danger, say researchers
An ongoing rise in atmospheric carbon dioxide from burning of fossil fuels might be kept below harmful levels if emissions from coal are phased out within the next few decades, say researchers.   view more (2008-09-15)

My, what big teeth you had! Extinct species had large teeth on roof of mouth
When the world's land was congealed in one supercontinent 240 million years ago, Antarctica wasn't the forbiddingly icy place it is now. But paleontologists have found a previously unknown amphibious predator species that probably still made it less than hospitable.   view more (2008-09-12)

Ice core studies confirm accuracy of climate models
An analysis has been completed of the global carbon cycle and climate for a 70,000 year period in the most recent Ice Age, showing a remarkable correlation between carbon dioxide levels and surprisingly abrupt changes in climate.   view more (2008-09-12)

NASA study illustrates how global peak oil could impact climate
The burning of fossil fuels -- notably coal, oil and gas -- has accounted for about 80 percent of the rise of atmospheric carbon dioxide since the pre-industrial era. Now, NASA researchers have identified feasible emission scenarios that could keep carbon dioxide below levels that some scientists... view more (2008-09-11)

New NIST publication series addresses design of earthquake-resistant structures
Where can you find some of the latest insights in designing earthquake-resistant buildings joined together with current information on building codes?   view more (2008-09-05)

Arctic ice on the verge of another all-time low
Following last summer's record minimum ice cover in the Arctic, current observations from ESA's Envisat satellite suggest that the extent of polar sea-ice may again shrink to a level very close to that of last year.   view more (2008-08-29)

Why is Greenland covered in ice?
There have been many reports in the media about the effects of global warming on the Greenland ice-sheet, but there is still great uncertainty as to why there is an ice-sheet there at all.   view more (2008-08-28)

New Speed Record for Magnetic Memories
Fast memory chips such as DRAMs and SRAMs (Dynamic and Static Random Access Memory) commonly used today have one decisive disadvantage: in case of power interruption, they lose their stored information.   view more (2008-08-19)

Antarctic Fossils Paint a Picture of a Much Warmer Continent
National Science Foundation-funded scientists working in an ice-free region of Antarctica have discovered the last traces of tundra--in the form of fossilized plants and insects--on the interior of the southernmost continent before temperatures began a relentless drop millions of years ago.   view more (2008-08-06)

Patagonian glacier yields clues for improved understanding of global climate change
A better understanding of climate variations at planetary scale is one of climate scientists' crucial concerns. Stable water isotope analysis, the chemistry of ice cores taken from the Arctic and Antarctic polar ice caps and of air bubbles trapped in them now allow a chronology to be drawn up of... view more (2008-08-05)

Drinking in excess associated with increased risk for metabolic syndrome
Those who drink in excess of the U.S. Dietary Guidelines (i.e., men who usually drink more than two drinks per day or women who usually drink more than one drink per day) or those who binge drink are at increased risk for the metabolic syndrome, according to a new study accepted for publication in... view more (2008-07-30)

Snapshot of past climate reveals no ice in Antarctica millions of years ago
A snapshot of New Zealand's climate 40 million years ago reveals a greenhouse Earth, with warmer seas and little or no ice in Antarctica, according to research published this week in the journal Geology.    view more (2008-07-29)

Unique fossil discovery shows Antarctic was once much warmer
A new fossil discovery- the first of its kind from the whole of the Antarctic continent- provides scientists with new evidence to support the theory that the polar region was once much warmer.   view more (2008-07-23)
