Atlantic Hurricanes Doubled Over Last Century

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

THE BIG PICTURE

You expect the big picture, and it's our job at Mother Jones to give it to you. And right now, so many of the troubles we face are the making not of a virus, but of the quest for profit, political or economic (and not just from the man in the White House who could have offered leadership and comfort but instead gave us bleach).

In "News Is Just Like Waste Management," we unpack what the coronavirus crisis has meant for journalism, including Mother Jones’, and how we can rise to the challenge. If you're able to, this is a critical moment to support our nonprofit journalism with a donation: We've scoured our budget and made the cuts we can without impairing our mission, and we hope to raise $400,000 from our community of online readers to help keep our big reporting projects going because this extraordinary pandemic-plus-election year is no time to pull back.
