The Double O's Were the Hottest Years on Record
The report was produced by more than 300 scientist in 48 countries, using ten separate planet-wide features as barometers. "The findings do not include data from 2010, which is on pace to exceed the highest annual average global temperature ever recorded, NOAA said." This year has already seen extreme heat events in the eastern United States, Europe, Russia and the Middle East.
"According to the report, each decade since the 1980s has been progressively warmer than the last, with an average warming of about one-fifth of a degree Fahrenheit per decade."
