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.

MORE HARD-HITTING JOURNALISM

In 2014, before Donald Trump announced his run for president, we knew we had to do something different to address the fundamental challenge facing journalism: how hard-hitting reporting that can hold the powerful accountable can survive as the bottom falls out of the news business.

Being a nonprofit, we started planning The Moment for Mother Jones, a special campaign to raise $25 million for key investments to make Mother Jones the strongest watchdog it can be. Five years later, readers have stepped up and contributed an astonishing $23 million in gifts and future pledges. This is an incredible statement from the Mother Jones community in the face of huge threats—both economic and political—against the free press.

Read more about The Moment and see what we've been able to accomplish thanks to readers' incredible generosity so far, and please join them today. Your gift will be matched dollar for dollar, up to $500,000 total, during this critical moment for journalism.
