Predators drive the lemming cycle in Greenland
A recent study conducted in eastern Greenland and published in the October 31 issue of the Science magazine provides new understanding of the dynamics of arctic lemming populations. Olivier Gilg and Ilkka Hanski from the University of Helsinki, Finland, and Beno'®t Sittler from the University of Freiburg, Germany, combined long-term field... view more... (2003-10-29)
Geologists discover signs of volcanoes blowing their tops in the deep ocean
A research team led by the Woods Hole Oceanographic Institution (WHOI) has uncovered evidence of explosive volcanic eruptions deep beneath the ice-covered surface of the Arctic Ocean. view more (2008-06-26)
Decline in greenhouse gas emissions would reduce sea-level rise, save Arctic Sea ice
The threat of global warming can still be greatly diminished if nations cut emissions of heat-trapping greenhouse gases by 70 percent this century, according to a new analysis. view more (2009-04-15)
Aerosols may drive a significant portion of arctic warming
Though greenhouse gases are invariably at the center of discussions about global climate change, new NASA research suggests that much of the atmospheric warming observed in the Arctic since 1976 may be due to changes in tiny airborne particles called aerosols. view more (2009-04-09)
2007 was tied as Earth's second warmest year
Climatologists at the NASA Goddard Institute for Space Studies (GISS) in New York City have found that 2007 tied with 1998 for Earth's second warmest year in a century. view more (2008-01-17)
Successful series of measurements in Arctic sea ice
The German Research Vessel Polarstern had to prove its ice breaking capabilities in Arctic waters to gain data on two series of long-term research measurements. After working in regions up to latitude 82° N, Polarstern of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association will enter port in Reykjavik... view more...

Less Arctic ice means higher risks, experts warn
The International Ice Charting Working Group predicts more marine transportation in the Arctic as sea ice continues to diminish and warns of "significant hazards to navigation," according to a statement released yesterday. view more (2007-10-29)
Scientists head to warming Alaska on ice core expedition
The state of Alaska has the dubious distinction of leading the lower 48 in the effects of a warming climate. Small villages are slipping into the sea due to coastal erosion, soggy permafrost is cracking buildings and trapping trucks. view more (2008-04-30)
Higher Water Temperatures and Reduced Ice Cover In the Arctic Ocean
Over the past six weeks, scientists aboard the research vessel "Polarstern" of the Alfred Wegener Institute for Polar and Marine Research have been investigating changes in ocean temperature and sea ice cover in the area of Fram Strait between Spitsbergen and Greenland. In this area significant exchange of water masses between the Arctic Ocean... view more... (2004-08-27)
Permafrost Becomes Insecure
Russian scientists have discovered territories in the North that will run the greatest risk in the course of permafrost thawing, they have also calculated degree of risk for towns, industrial facilities and main lines. Global climate warming makes attacks on permafrost. Accurate forecast is very important as the permafrost ground status would... view more... (2004-03-26)
Warmer air may cause increased Antarctic sea ice cover
Predicted increases in precipitation due to warmer air temperatures from greenhouse gas emissions may actually increase sea ice volume in the Antarctic's Southern Ocean. view more (2005-06-30)
Global Warming: Cuts in Greenhouse Gas Emissions Would Save Arctic Ice, Reduce Sea Level Rise
The threat of global warming can still be greatly diminished if nations cut emissions of heat-trapping greenhouse gases by 70 percent this century, according to a new analysis. view more (2009-04-15)
World premier for newly composed music for ice instruments
World premier for newly composed music for ice instruments: The ensemble "Voices of Ice" play at the Ice Globe Theater in the northern part of Sweden. Tuesday, March 18 is the world premier at the Ice Globe Theater in Jukkasj'Īrvi for two newly composed musical pieces by the Swedish composers Karin Rehnqvist and Bill Brunson. The music... view more... (2003-03-11)
Scientists use meteors to investigate climate change and giant waves at the 'edge of space'
A new research radar based in Antarctica is giving scientists the chance to study the highest layer of the earth's atmosphere at the very edge of space. view more (2005-05-23)
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)
Journey to the center of the earth: Discovery sheds light on mantle formation
Uncovering a rare, two-billion-year-old window into the Earth's mantle, a University of Houston professor and his team have found our planet's geological history is more complex than previously thought. view more (2008-04-11)
Working with Inuit Community Is Part of Scientific Expedition
Research on global warming is drawing scientists in increasing numbers to the world's polar regions. But as scientists make more journeys northward, some of them find that their mission now extends beyond the ice or sediment samples they will bring back to their labs to analyze. view more (2007-05-17)
Biologists: Greening Arctic not likely to offset permafrost carbon release
As the frozen soil in the Arctic thaws, bacteria will break down organic matter, releasing long-stored carbon into the warming atmosphere. view more (2009-05-28)
Decline of Shorebird Linked to Bait Use of Horseshoe Crabs
Declining numbers of a shorebird called the red knot have been linked to bait use of horseshoe crabs. view more (2009-02-18)
Explorers to Use New Robotic Vehicles to Hunt for Life and Hydrothermal Vents on Arctic Seafloor
Scientists and engineers from the Woods Hole Oceanographic Institution (WHOI) have just completed a successful test of new robotic vehicles designed for use beneath the ice of the Arctic Ocean. view more (2007-06-25)
