Rapid Sea Level Rise in the Arctic Ocean May Alter Views of Human Migration
Scientists have found new evidence that the Bering Strait near Alaska flooded into the Arctic Ocean about 11,000 years ago, about 1,000 years earlier than widely believed, closing off the land bridge thought to be the major route for human migration from Asia to the Americas.    view more (2006-10-12)

Siberian lakes burp "time-bomb" greenhouse gas
Frozen bubbles in Siberian lakes are releasing methane, a greenhouse gas, at rates that appear to be "... five times higher than previously estimated" and acting as a positive feedback to climate warming, said Katey Walter, in a paper published today in the journal Nature.   view more (2006-09-08)

Arctic ice meltdown continues with significantly reduced winter ice cover
As far as temperatures drop in the Arctic winter - on average to -34°C (-29°F) - a new study shows that in the last two years sea ice is shrinking on the surface of Arctic waters to record low levels.   view more (2006-09-14)

Most of Arctic's Near-Surface Permafrost May Thaw by 2100
Global warming may decimate the top 10 feet (3 meters) or more of perennially frozen soil across the Northern Hemisphere, altering ecosystems as well as damaging buildings and roads across Canada, Alaska, and Russia.   view more (2005-12-20)

Marine Biology Mystery Solved: Function of "Unicorn" Whale's 8-foot Tooth Discovered
Today, Harvard School of Dental Medicine (HSDM) researcher Martin Nweeia, DMD, DDS, answers a marine science question that has eluded the scientific community for hundreds of years: why does the narwhal, or "unicorn," whale have an 8-foot-long tooth emerging from its head, and what is its function?   view more (2005-12-14)

Icy calculations on a hot topic
University of Utah mathematicians have arrived at a new understanding of how salt-saturated ocean water flows through sea ice - a discovery that promises to improve forecasts of how global warming will affect polar icepacks.   view more (2007-09-11)

The Arctic and Global Warming
A warmer Arctic Ocean may mean less food for the birds, fish, and baleen whales and be a significant detriment to that fragile and interconnected polar ecosystem, and that doesn't bode well for other ocean ecosystems in the future.   view more (2006-02-21)

2005 Was the Warmest Year in a Century
The year 2005 may have been the warmest year in a century, according to NASA scientists studying temperature data from around the world.   view more (2006-01-25)

Pollutant haze heats the Arctic
Arctic climate already is known to be particularly prone to global warming caused by industrial and automotive emissions of carbon dioxide and other greenhouse gases.   view more (2006-05-11)

Movement of Earth's North Magnetic Pole Accelerating Rapidly
After some 400 years of relative stability, Earth's North Magnetic Pole has moved nearly 1,100 kilometers out into the Arctic Ocean during the last century and at its present rate could move from northern Canada to Siberia within the next half-century.   view more (2005-12-12)

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)

Climate History Rewritten: Arctic Ice an Early Arrival
For the first time, scientists have pulled up prehistoric geologic records from the frigid vault of the Arctic Ocean. One of the findings, evidence of glacial Arctic ice from 45 million years ago, recasts a critical chapter of global climate history.   view more (2006-06-01)

Arctic sea ice declines again in 2006, say University of Colorado researchers
While cool August temperatures prevented sea ice in the Arctic from reaching its lowest summer extent on record, 2006 continued a pattern of sharp annual decreases due to rising temperatures probably caused by greenhouse warming.   view more (2006-10-05)

Deep in Arctic Mud, Geologists Find Strong Evidence of Climate Change
How severe will global warming get? Jason P. Briner is looking for an answer buried deep in mud dozens of feet below the surface of lakes in the frigid Canadian Arctic.    view more (2007-01-19)

Dissapearing arctic lakes linked to climate change
Continued arctic warming may be causing a decrease in the number and size of Arctic lakes. The issue is the subject of a paper published in the June 3 issue of the journal "Science." The paper, titled, "Disappearing Arctic Lakes" is the result of a comparison of satellite data taken of Siberia in the early 1970s to data from... view more... (2005-06-06)

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)

Ancient Arctic water cycles are red flags to future global warming
Ancient plant life recovered in recent Arctic Ocean sampling cores shows that at the time of the last major global warming, humidity, precipitation levels and salinity of the ocean water altered drastically, along with the elevated temperatures and levels of greenhouse gases.   view more (2006-08-14)

Warming climate may put chill on arctic polar bear population
Some travel agencies touting Arctic tours have been revving up their recent promotions to tourists about the increased likelihood they will spot polar bears in this region where several populations of polar bears live.   view more (2006-09-14)

Scientists discover new life forms in the Arctic Ocean
