Atlantic Hurricanes Doubled Over Last Century

Let our journalists help you make sense of the noise: Subscribe to the Mother Jones Daily newsletter and get a recap of news that matters.


About twice as many Atlantic hurricanes form each year on average than a century ago. This according to a new analysis by researchers at the National Center for Atmospheric Research and the Georgia Institute of Technology. Warmer sea surface temperatures (SSTs) and altered wind patterns associated with global climate change are fueling much of the increase. The analysis identifies three periods since 1900, separated by sharp transitions, during which the average number of hurricanes and tropical storms increased dramatically and then remained elevated and relatively steady. SSTs have risen by about 1.3 degrees F in the last 100 years, and other studies indicate that most of the rise in Atlantic sea surface temps can be attributed to global warming. “Even a quiet year by today’s standards would be considered normal or slightly active compared to an average year in the early part of the 20th century,” says study author, Greg Holland.

By the way, the current period has not yet stabilized. So the average hurricane season could be even more active in the future. . . The planet lives and breathes in powerful ways. Here’s an amazing video recap of some of the 2005 hurricane season. Stunningly beautiful. Terrifying. JULIA WHITTY

IT'S NOT THAT WE'RE SCREWED WITHOUT TRUMP:

"It's that we're screwed with or without him if we can't show the public that what we do matters for the long term," writes Mother Jones CEO Monika Bauerlein as she kicks off our drive to raise $350,000 in donations from readers by July 17.

This is a big one for us. It's our first time asking for an outpouring of support since screams of FAKE NEWS and so much of what Trump stood for made everything we do so visceral. Like most newsrooms, we face incredibly hard budget realities, and it's unnerving needing to raise big money when traffic is down.

So, as we ask you to consider supporting our team's journalism, we thought we'd slow down and check in about where Mother Jones is and where we're going after the chaotic last several years. This comparatively slow moment is also an urgent one for Mother Jones: You can read more in "Slow News Is Good News," and if you're able to, please support our team's hard-hitting journalism and help us reach our big $350,000 goal with a donation today.
