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

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
