NASA makes it official: We have set the 12-month record, just as CP pointed a few weeks ago (see “NASA: Easily the hottest April — and hottest Jan-April — in temperature record“) — and that is all the more powerful evidence of human-caused warming “because it occurs when the recent minimum of solar irradiance is having its maximum cooling effect,” as the paper notes. This didn’t make a lot of news — see this tiny Bloomberg story — nothing compared to all the nonsensical stories about global cooling.
But will 2010 actually set the record for the hottest calendar year? NASA explains:
It is likely that global temperature for calendar year 2010 will exceed the 2005 record, but that is not certain if a deep La Nina develops quickly.
