GISS Still Diverging From Satellites
By Paul Homewood
Joe Romm seems to be getting worked up again about “record temperatures”!
There had never been as hot a 12-month period in NASA’s database as February 2014–January 2015. But that turned out to be a very short-lived record.
NASA reported this weekend that last month was the second-hottest February on record, which now makes March 2014–February 2015 the hottest 12 months on record. This is using a 12-month moving average, so we can “see the march of temperature change over time,” rather than just once every calendar year.
We are experiencing the continuation of the global warming trend that made 2014 the hottest calendar year on record. The very latest science says we should expect an acceleration in surface temperature warming to start quite soon. What is happening now is consistent with that.
In fact, the 12-month running average of 0.70C is only one hundredth of a degree higher than it was in May 2007, after a similar run of El Nino months.
Meanwhile Romm forgets to mention that GISS temperatures continue to diverge from both UAH and RSS satellites.
