2017 Set an Astonishing New Temperature Record

The 2017 temps are in, and NASA reports that 2017 was the second-hottest year on record. On a global basis, 2017 was 0.9ºC hotter than the 20th century average. More importantly, it was the hottest by far outside of El Niño years. 2017 was an astonishing 0.26°C hotter than the previous hottest non-El Niño year.

Just for a change of pace, though, let’s take a look at temperatures in the northern hemisphere, since that’s where most of us live. For the last couple of decades, the northern hemisphere has been heating up considerably more than the planet as a whole: in 2017, the northern hemisphere was a full 1.11ºC hotter than the 20th century average. Here’s the 50-year temperature record for the northern hemisphere:

And here are northern hemisphere temps solely for years without an El Niño event. 2017 was 0.28°C hotter than the previous record holder:

Just more fake news, I suppose.
