In 2008, I took a tiny cargo plane to the Inupiaq village of Kivalina, in the northwest of Alaska above the Arctic Circle. I had heard the village would be lost to climate change from erosion, which I imagined to be a slow, gradual, and predictable process. Touring the island and speaking to residents and government workers, I soon realized the erosion is actually often sudden, severe, and erratic, brought on by...
… the 2010 September ice volume anomaly did in fact exceed the previous 2007 minimum by a large enough margin to establish a statistically significant new record. via Arctic Death Spiral: Second Lowest June Sea Ice Extent, Lowest June Volume | ThinkProgress.
Arctic sea ice volume: The death spiral continues « Climate Progress In November, Rear Admiral David Titley, the Oceanographer of the Navy, testified that “the volume of ice as of last September has never been lower…in the last several thousand years.”Titley, who is also the Director of Navy’s Task Force Climate Change, said he has told the Chief of Naval Operations that “we expect to see four weeks of basically ice free conditions in...
The GRACE satellites continue to measure the change in gravity around the Greenland ice sheet. Here is the latest data showing the record amount of ice loss Greenland experienced in the 2010 summer. H/T to Tenney Naumer from Climate Change: The Next Generation and Dr John Wahr at the University of Colorado who analysed the GRACE data and granted permission to reproduce it here. Figure 1: Greenland ice mass anomaly – deviation from the...
The disinformers and many in the media love to focus on where it is cold in the winter. It has been cool where many people live. Brr! Unfortunately for homo sapiens, it’s been staggeringly warm where the ice is. I’ll do a post on Greenland shortly, but the NSF-sponsored researchers at UCAR/NCAR have posted some staggering data on just how warm it has been in northern Canada: To put this picture into even sharper...
Greenland rising faster as ice loss acceleratesWe have several independent lines of evidence that Greenland is losing ice at an accelerating rate. Satellite altimetry find glaciers are sliding faster downhill and dumping more ice into the ocean. Altimetry data also find the ice sheet is thinning. An overall picture is obtained by satellites measuring the gravity around the ice sheet. Another line of evidence has now been added to this picture with GPS measurements...
While the anti-science crowd scours the globe desperately looking for any indication of their imaginary cooling, reality has intruded again.Because they and the media — and even some scientists who don’t follow the subject closely — tend to take a two-dimensional view of the Arctic, they along with much of the public have been fooled into thinking the Arctic “recovered” in the past two years because sea ice extent appeared to recover. Heck, some...
