Plastic Particles Infest the Arctic

Tim Radford / Climate News Network Apr 28, 2018 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. Dig deeper ( 2 Min. Read )

Arctic Finishes Warmest Winter on Record

SETH BORENSTEIN / The Associated Press Mar 6, 2018 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. Dig deeper ( 3 Min. Read )

Scientists Calculate That Humans Cause at Least Half the Loss of Arctic Sea Ice

By Tim Radford / Climate News Network Mar 17, 2017 New research analyzes the decline of the region's ecology by weighing natural variability and human factors. Dig deeper ( 2 Min. Read )

Poles Apart: Sea Ice Melts—and Grows

By Alex Kirby, Climate News Network Oct 5, 2013 The Antarctic ice sheet continues to grow slightly, while Arctic sea ice is still melting fast. Scientists think climate change can explain both phenomena. Dig deeper ( 3 Min. Read )

Arctic Sea Ice Reaches Lowest Extent for 2013

By Alex Kirby, Climate News Network Sep 22, 2013 The amount of sea ice in the Arctic appears to have reached its lowest level in 2013 -- more than last year, but well below the long term average. Dig deeper ( 2 Min. Read )

Arctic Ice Loses Volume Fast

Staff / Truthdig Feb 17, 2013 Researchers say the Arctic sheet is not only shrinking in area, but also losing much of its volume by thinning. Dig deeper ( 3 Min. Read )

Why an Unusually Melty Arctic Means Trouble

Staff / Truthdig Oct 5, 2011 Dr. Tom Wagner of NASA is remarkably cheerful as he explains how the historic melting of sea ice in the Arctic threatens to exacerbate climate change across the globe. Dig deeper ( 1 Min. Read )

Arctic Has Lost Enough Ice to Cover Texas

Staff / Truthdig Apr 7, 2009 Although this wasn't the worst winter on record for retention of Arctic sea ice, a report from NASA and the National Snow and Ice Data Center says that the region is now missing a Texas-sized chunk of the stuff that keeps polar bears alive and cities above sea level. More alarming, the ice that is there is younger, thinner and more fragile than in years past. Dig deeper ( 1 Min. Read )

Ozone Pollution Is More Harmful Than Realized

Staff / Truthdig Mar 15, 2006 Ozone, which had been considered a minor player in global climate change, is actually a major factor in the dramatic warming of the Arctic zone, according to NASA. Worse, scientists are reporting that climate change is "irreversible," as Arctic sea ice has failed to re-form for the second year in a row. Dig deeper ( 1 Min. Read )
