With only one month left in the year, 2020 has a 54% chance of becoming the hottest year on record.
Though hindsight isn’t quite 2020 yet, climate change has left plenty to remember over the past 10 years. This release covers warming temperatures by the decade, with clear trends at the local, national, and global scales.
According to the December 2020 outlook from NOAA’s Climate Prediction Center, much of the contiguous United States is expected to observe a warmer and drier-than-average end of the year.
NOAA and NASA’s global temperature data is in – 2019 was the 2nd hottest year on Earth since records began, making the 2010s the hottest decade on record.
Rising temperatures sometimes seem most noticeable during periods of extreme heat such as summer heat waves. However, for much of the U.S., winter is the fastest warming season. Cold weather still occurs in a warming climate but, on average, winters are not as cold as they used to be and cold snaps that do happen are becoming shorter and less frequent.
