No warming signal found in study of frozen ground changes over past ~ 20 years
The Hockey Schtick
December 7,2011 EXCERPT: A paper published today in Environmental Research Letters examines a 71 year history of seasonally frozen ground changes in Eurasia. The paper finds freeze depths decreased (indicative of warming) between the late 1960's to early 1990's, but that "from that point forward, likely through at least 2008, no change is evident." The paper finds the observed changes linked to the North Atlantic Oscillation (NAO), a natural climate cycle, rather than the uncorrelated steady rise in 'greenhouse gases.' LINK The Abstract is in the link It is our attitude toward free thought and free expression that will determine our fate. There must be no limit on the range of temperate discussion, no limits on thought. No subject must be taboo. No censor must preside at our assemblies. –William O. Douglas, U.S. Supreme Court Justice, 1952 |
