Arctic Ice Decline Much Worse Than Expected

As the extent of Arctic sea ice declines to levels unrecorded since satellite monitoring began, the National Snow and Ice Data Center has released a new analysis that shows the situation to be worse by far than even the most pessimistic models predicted.

It's a perverse endorsement of one of the most popular denier memes - that you can't rely on climate models because the world is too complicated to be reduced to a compilation of computer data. But, thanks to the expertise (and conservative nature) of the scientists behind this work, the models have shown the direction with perfect accuracy: it's the terrifying extent that they have failed to anticipate.

In addition to the catastrophic conditions currently prevailing in the Arctic, the NSIDC has also drawn attention to the dramatic melting occurring this year in Greenland. And all this is supported and reinforced by the Polar Science Center's ongoing calculation of Arctic ice volume.

The trends are all down. Or as James Hansen put it in the Washington Post last week, “Climate change is here - and it's worse than we thought.”

Climate Denial Crock of the Week/1998 Revisited

One of the enduring myths of climate denialism is that global warming stopped sometime in the last decade. I see it in the blaring headlines of pseudoscience websites, in comments on my videos, even some of our most “distinguished” journalists have been taken in.

Arctic Starts Annual Melt, Balancing on Thin Ice

Arctic ice has maxed out for the year and is starting its slow melt into summer in much worse shape than normal, according to the National Snow and Ice Data Centre.

If you look only at the extent of Arctic sea ice, things are not as bad as they have been in recent years. Ice cover is five per cent higher this year than in the record low 2006, even if it is four per cent lower than the 1979 to 2000 average.

 

But ice thickness is another story, and that seems to be all bad news.

Arctic Ice at Historic Minimum

“The ice thickness was fairly constant for the five winters before this, but it plummeted in the winter after the 2007 minimum.”

- lead author Dr. Katharine Giles

A new study, conducted by academics from University College London, published in Geophysical Research Letters and reported by the BBC, shows that the total mass of Arctic ice has dropped to the lowest level ever recorded by satellite.

Arctic Melt Now Second Worst

Sea ice extent has fallen below the 2005 minimum, previously the second-lowest extent recorded since the dawn of the satellite era, the U.S. National Snow and Ice Data Center reported last week.
