Tuesday, December 11, 2007


I was too quick to talk about a "cooling trend" yesterday. As James Hansen points out today in his email blast:
Through the first 11 months, 2007 is the second warmest year in the period of
instrumental data, behind the record warmth of 2005, in the Goddard Institute for Space Studies (GISS) analysis. The unusual warmth in 2007 is noteworthy because it occurs at a time when solar irradiance is at a minimum and the equatorial Pacific Ocean has entered the cool phase of its natural El Nino – La Nina cycle.
