Climate shifts — probability of randomness
Severe climate changes during the last ice-age could have been caused by random chaotic variations on Earth and not governed by external periodic influences from the Sun. This has been shown in new calculations by a researcher at the Niels Bohr Institute, Copenhagen University. view more (2007-03-12)
Glaciers and ice caps to dominate sea level rise this century, says CU-Boulder study
Ice loss from glaciers and ice caps is expected to cause more global sea rise during this century than the massive Greenland and Antarctic ice sheets, according to a new University of Colorado at Boulder study. view more (2007-07-20)
Unearthing explanations for New Madrid earthquakes
On Dec. 16, 1811, residents of New Madrid, Mo., were wrested from sleep by violent shaking and a deafening roar. A short time later, church bells hundreds of miles away in Boston began to ring. view more (2006-02-21)
Arctic sea ice diminished rapidly in 2004 and 2005
The Arctic Ocean's perennial sea ice, which survives the summer melt season and remains year-round, shrank abruptly by 14 percent between 2004 and 2005, according to a newly published study. view more (2006-09-14)
Ice Scalpel For Explosives
How can a tin be opened if it contains not tinned goods but explosives? Or a shell or something no less dangerous, for instance, a retired nuclear reactor? view more (2005-04-29)
What are 3-D spider webs for?
The classic radial or "orb" spider web captures flying insects efficiently with a small amount of silk but such flat webs leave spiders exposed to their own predators. The derived "araneoid sheet web weavers" transformed the flat orb web into, usually, three-dimensional cobwebs and sheet webs. These webs surround spiders with tangles of silk that... view more...

Britain populated rapidly after ice age
Research News from the Journal of Quaternary Science 13 October 2003: New data show that humans responded rapidly to climate change and moved into Britain en masse almost as soon as the last ice age ended. This challenges the previously held view that repopulation was a slow process led by a few pioneering explorers. Recent innovations have... view more... (2003-10-13)
Russia Returns To Arctic On A Drifting Ice-floe
After a long break Russia is getting ready to resume the research in Arctic with the help of floating stations. As Valery Martyshenko (Rosgidromet) has advised InformNauka, an appropriate ice-floe is currently being looked for, and the 32nd station will start the floating in the last decade of April. Vladimir Sokolov, Head of the SP-32 floating... view more... (2003-03-25)
'New' ancient Antarctic sediment reveals climate change history
Recent additions to the premier collection of Southern Ocean sediment cores at Florida State University's Antarctic Marine Geology Research Facility will give international scientists a close-up look at fluctuations that occurred in Antarctica's ice sheet and marine and terrestrial life as the climate cooled considerably between 20 and 14 million... view more...

Data show Antarctic ice stream radiating seismically
A seismologist at Washington University in St. Louis and colleagues at Pennsylvania State University and Newcastle University in the United Kingdom have found seismic signals from a giant river of ice in Antarctica that makes California's earthquake problem seem trivial. view more (2008-06-05)
Arctic sea ice minimum shatters all-time record low, report University of Colorado scientists
Scientists from the University of Colorado at Boulder's National Snow and Ice Data Center said today that the extent of Arctic sea ice appears to have reached its minimum for 2007 on Sept. 16, shattering all previous lows since satellite record-keeping began nearly 30 years ago. view more (2007-09-21)
Researchers link Ice Age climate-change records to ocean salinity
Sudden decreases in temperature over Greenland and tropical rainfall patterns during the last Ice Age have been linked for the first time to rapid changes in the salinity of the north Atlantic Ocean. view more (2006-10-05)
From Europa To Sedna - Life Beneath The Ice In The Outer Solar System?
At present, we know of no worlds beyond our Earth where life exists. However, primitive organisms on our planet have evolved and adapted over billions of years, colonising the most inhospitable places. Since life seems to gain a foothold in the most hostile environments, it seems distinctly possible that living organisms could exist in... view more... (2004-03-25)
Antarctic seabirds and climate change
Recent changes in Antarctic seabird populations may be linked to environmental change according to scientists reporting in the journal Science this week. Researchers from the Cambridge-based British Antarctic Survey (BAS) reviewed the best available data from a range of long-term studies to test the view that warming of the Earth`s climate is... view more...

Close relationship between past warming and sea-level rise
In a paper in Nature Geoscience, a team from the National Oceanography Centre, Southampton (NOCS), along with colleagues from Tübingen (Germany) and Bristol presents a novel continuous reconstruction of sea level fluctuations over the last 520 thousand years. view more (2009-06-23)
Researchers say Arctic sea ice still at risk despite cold winter
Using the latest satellite observations, NASA researchers and others report that the Arctic is still on "thin ice" when it comes to the condition of sea ice cover in the region. A colder-than-average winter in some regions of the Arctic this year has yielded an increase in the area of new sea ice, while the older sea ice that lasts for... view more... (2008-03-19)
Robot submarine reveals secret stash of key Antarctic food source under sea ice
A robot submarine expedition under the Antarctic sea ice has discovered a major food reserve in the Southern Ocean. The findings, reported this week in SCIENCE, show a dense band of the shrimp-like krill under the ice, five times more concentrated than in open water. The importance of sea ice as a nursery for krill - key food for penguins, whales... view more... (2002-03-05)
Global warming may not have ended Ice-Age, says research
Scientists at the University of Sheffield have used fossilised leaves to determine the effect of greenhouse gases on the end of the Ice Age 300m years ago, according to an article published in PNAS. The study, led by Professor David Beerling, examined fossilised leaves to determine how much carbon dioxide was in the air at various periods during... view more... (2002-09-12)
Strengthening case for life on Mars - CMD19CMMP with The Physics Congress 2002
When it was announced last month that the Mars Odyssey satellite had found water ice beneath the planet`s frozen carbon dioxide south polar ice cap, "I felt excited!" says Dr Lidija Siller, a physicist from the University of Newcastle. "I believe that the data I have explains how this water became trapped underneath the surface". Dr Siller will be... view more... (2002-03-26)
Scientists Detect Melting of Antarctic Ice Shelf
A giant ice shelf the size of Scotland is melting rapidly in warm Antarctic waters, a report in SCIENCE will reveal today. Thinning of the Larsen Ice Shelf - vast sections of which collapsed catastrophically during the 1990's - was discovered by scientists at the University of Cambridge, University College London, University of Bristol and the... view more...
