NOAA Press Advisory On Arctic Ice Minimum – Key Graphs Here

September 20, 2012

Above,  the final graph of this year’s record low sea ice minimum for the Arctic. Here are the key points and images related to arctic ice.

A view showing arctic sea ice minimums since 1979, reflecting ice loss in the satellite era. Note that ice loss in either of the record years 2007 and 2012 is almost equal to the total loss from 1979 to 2005 – an accelerating trend.

Above, a comparative view of arctic ice loss against the continental US. An area equivalent to the US East of the Mississippi, plus most of the great plains, is now open water that just a few decades ago, was covered with ice. This open water, say scientists, will most certainly have unpredictable effects on the jet stream, and thus, weather events, in coming months, across the northern hemisphere temperate zones. See this video for more.

Changes in arctic ice thickness, and thus, total ice mass. The area of thick “perennial” ice is vastly reduced.
