Arctic Sea ice well on its way to disappearing this summer? Part III

: This post is an update to the posts of June 1 and July 10, 2008, on the condition of the Arctic Sea ice and Greenland's ice sheet melt.

From Polar View at the Technical University of Denmark (
Composite images from July 27, 2008:

From the Cryosphere Today site (run by the Universities of Illinois and Colorado), a comparison of the Arctic on July 9, 2007 and 2008, and July 22, 2007 and 2008:

Go to this link and put in dates for comparison -- the most recent day is usually available before the evening:

The graphics below are from NOAA of global sea surface temperature anomalies on July 10 and 24, 2008.

The image below is a NOAA graphic of the 500-hPa height anomalies in the Northern Hemisphere on July 2, 2008. Click on the link below the graphic to see the most recent 30-day animation.

Link to photos (NOTE: to see photos from other days from 2008, change the 191 to the number of the day that you want, e.g., 190 is July 8, and so forth):

I find the image below fascinating (and it is the scariest of all):

Link to updated TLT channel temperature anomalies graph (NOTE: often due to volume of traffic it is not possible to access the link -- try again later):

And, below, find an animation of global surface temperature anomalies for the past 30 days -- most disturbing are the anomalies occurring at Antarctica many of which are much higher than 20 C.
