Last year was not the hottest year on record in the United States; it was only the second hottest. 2012 was the hottest because of some searing heat waves that summer. However, 2016 marked 20 above-average temperature years in a row. The five hottest years recorded have all happened since 1998. Every state had a temperature ranking at least in the top seven and both Georgia and Alaska had their hottest years ever. While it was only the second hottest year on record in the U.S., last year was the hottest year for the entire world.
