Just a few short weeks after NOAA operations wrote that 2012′s La Niña was the warmest on records, NOAA researchers announced they recalculated historical La Niñas because of warming global temperatures. NOAA confirmed something that occurred to me while I was writing that post: eventually, historical El Niños will be cooler than future La Niñas.

According to data released by NASA and NOAA this week, 2012 was the 9th or 10th warmest year (respectively) globally on record. NASA’s analysis produced the 9th warmest year in its dataset; NOAA recorded the 10th warmest year in its dataset. The two agencies have slightly different analysis techniques, which in this case resulted in not only different temperature anomaly values but somewhat different rankings as well.

According to data released by NASA and NOAA this week, July 2012 was the 12th and 4th warmest July (respectively) globally on record. NASA’s analysis produced the 12th warmest July in its dataset; NOAA recorded the 4th warmest July in its dataset. The two agencies have slightly different analysis techniques, which in this case resulted in not only different temperature anomaly values but rather different rankings as well.

NASA’s James Hansen and a few of his colleagues released their assessment of 2011 global temperatures recently. In short, 2011 was the 9th warmest year in the GISS dataset. After accounting for La Nina effects, it is the assessment of an overwhelming majority of climate scientists that global warming has not stopped.
