I sat in on NOAA's monthly climate webinar today where they briefed us on the state of the climate across the globe and over the US. Some highlights included them reporting that June 2012 was the 4th warmest June globally. On land it was the 1st warmest and 10th warmest over the ocean. The map below shows where it was abnormally warm this month. Most of North America shows a red dot with the largest anomalies over the western US. Hardest hit across the globe was over in Siberia.

 

Another interesting slide showed Arctic sea ice extent in June. They reported that last month had the 2nd smallest Arctic sea ice extent and had a record ice loss with 2.86 million square km melting.
