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.

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

Headshot of Editor in Chief of Mother Jones, Clara Jeffery

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
