NOAA’s latest global climate summary shows that for the earth as a whole, August 2017 was the third warmest on record, following 2016 (highest) and 2015 (second highest). In fact, the eastern US was one of the few places in the world with temperatures below average. The summer months of June through August 2017 were also the third warmest on record. For the year to date, 2017 was the second highest on record after 2016 due in part to the warm winter. Note that parts of the Southeast are still at a record high for the year to date.
