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

We've never been very good at being conservative.

And usually, that serves us well in doing the ambitious, hard-hitting journalism that you turn to Mother Jones for. But it also means we can't afford to come up short when it comes to scratching together the funds it takes to keep our team firing on all cylinders, and the truth is, we finished our budgeting cycle on June 30 about $100,000 short of our online goal.

This is no time to come up short. It's time to fight like hell, as our namesake would tell us to do, for a democracy where minority rule cannot impose an extreme agenda, where facts matter, and where accountability has a chance at the polls and in the press. If you value our reporting and you can right now, please help us dig out of the $100,000 hole we're starting our new budgeting cycle in with an always-needed and always-appreciated donation today.
