Change In Antarctic Sea Ice Trend Not So Extreme, Study Finds

July 25, 2014 by Joseph Romm

Antarctic Ice Change Study

A new study finds that the change in the trend of Antarctic sea ice growth over time is “not as extreme as the published literature indicates,” as one coauthor put it. The most important thing to know about Antarctica and ice is that a large part of the South Pole’s great sheet of land ice is close collapse.[read more]

Biggest Loser: Thawing Greenland Competes With Collapsing Antarctic For Fastest Ice Loss

May 23, 2014 by Joseph Romm

Shrinking Ice and Environmental Risk

The worst-case scenario for sea level rise has now become simply the “business-as-usual” scenario, recent studies from NASA make clear. NASA glaciologist Eric Rignot says that the new papers “suggest that the globe’s ice sheets will contribute far more to sea level rise than current projections show.”[read more]

NASA Research Indicates Slow, Irreversible West Antarctic Ice Melt

Irreversible Antarctic Melt

 

Recently released projections for the complete collapse of the West Antarctic ice sheet range from two hundred to nearly nine hundred years, but what is clear is that ice melt in this region of the southern pole is happening quicker than expected.[read more]

New Studies Suggest Many Coastal Cities Eventually To Be Abandoned With Antarctic Ice Collapse

Coastal Sea Level Risk to Cities

New studies in Science and Geophysical Research Letters find that glaciers in the Amundsen Sea region of the great Antarctic ice sheet have begun the process of irreversible collapse. That by itself would raise sea levels 4 feet in the coming centuries.[read more]

Study: Arctic Sea Ice Loss Shifts Jet Stream, Driving Deluges In Europe, Drought In Mediterranean

November 1, 2013 by Joseph Romm

Arctic Ice and Weather Patterns

Scientists predicted a decade ago that Arctic ice loss would shift storm tracks and bring on worse western droughts of the kind we are now seeing. Recent studies find that Arctic sea ice loss may well usher changes in the jet stream that lead to more U.S. extreme weather events.[read more]

Time to Sell That Ocean Front Property? New Study on Sea Level Rise

June 20, 2011 by Scott Edward Anderson

  Could Calvin Be Underwater?The rate of sea level rise along the U.S. Atlantic coast is greater now than at any time in the past 2,000 years, according to a new study published this week in the journal Proceedings of the National Academy of Sciences (PNAS). The study suggests a consistent link between changes in global mean...[read more]

NASA images of Mertz iceberg

February 27, 2010 by Lou Grinzo

Our friends at NASA have a page on their Earth Observatory site (which should be on your list of “check every day” sites, needless to say) about the Mertz iceberg, Collision Calves Iceberg from Mertz Glacier Tongue, Antarctica : Image of the Day: At 94 kilometers (58 miles) by 39 kilometers (24 miles) in size, the B-09B iceberg is...[read more]

Large Antarctic glacier thinning 4 times faster than it was 10 years ago: “Nothing in the natural world is lost at an accelerating exponential rate like this glacier.”

August 13, 2009 by Joseph Romm

A BBC story on the new study, “The spatial and temporal evolution of Pine Island Glacier thinning, 1995 – 2006,” (subs. req’d) explains: Calculations based on the rate of melting 15 years ago had suggested the glacier would last for 600 years. But the new data points to a lifespan for the vast ice stream of only another 100 years. The...[read more]

The Antarctic ice sheet hits the fan

January 14, 2008 by Joseph Romm

The global warming Deniers (and the rest of us) just can’t catch a break: Vast areas of the Antarctic ice sheet — which has 10 times as much ice as Greenland — is losing mass much faster than anyone expected. And the rate of ice loss has quickened in the last decade. In fact, 2007’s ice loss was 75% higher than 2006’s. Jeez, it’s almost...[read more]
