It's almost certain that 2016 will be the second-hottest year on record for the contiguous U.S., with new data showing that November was the second warmest on record for the Lower 48, capping off a record-hot autumn (for the second year in a row).

Through November, 2016 as a whole has been the second hottest in 122 years of record keeping, the National Oceanic and Atmospheric Administration announced Wednesday, and now there’s only one month to go.


Alaska, meanwhile, continues to see its hottest year by a large margin. All of these temperature records are in line with the broader warming of the planet caused by heat-trapping greenhouse gases that will also help 2016 easily beat out 2015 as the hottest year on record globally.
