Plastic Particles Infest the Arctic
Tiny bits have been found in every sample of Arctic sea ice collected. But the ice can only hold these indestructible pollutants for so long.
Arctic Species Changing as the Climate Warms
There are more herbivores and creatures that parasitize other animals, but those that consume carrion and decomposing plants seem to be on the way down, scientists say.
Polar Ice Is Melting Fast in Both Hemispheres
Two new British studies deliver ominous evidence of the long-term consequences of climate change due to the profligate use of fossil fuels.
Arctic Ice Depends on Half a Degree of Heat
That global temperature increment doesn’t sound like much, but it could make a world of difference to the polar ecosystem.
Arctic Finishes Warmest Winter on Record
Sea ice has hit record lows for this time of year, data also show. "It's just crazy, crazy stuff," says a scientist who has been studying the polar region since 1982.
As Arctic Sea Ice Thins, so Do Polar Bears

His five-year plan would open up federal waters off the California coast, as well as new areas off the East Coast from Georgia to Maine. Drilling in the affected regions has been blocked for decades.
Arctic Region Going Through 'Unprecedented Transition,' U.S. Government Warns
The National Oceanic and Atmospheric Administration reports that the current rates of Arctic warming and sea ice decline have not been seen in over one thousand years.
Scientists Calculate That Humans Cause at Least Half the Loss of Arctic Sea Ice
New research analyzes the decline of the region's ecology by weighing natural variability and human factors.
The Cold War Spurred Arctic Climate Research
Western postwar scientific studies in the Arctic were primarily driven by military concerns about Soviet activities in the region.
