Hurricane Seasons Wilder

Nature says so: the frequency and strength of Atlantic hurricanes has grown in recent decades. We’re now at levels now about as high as anything in the past 1,000 years. The data come from sediment samples along the North Atlantic coast and are analyzed alongside statistical models of the past 1,500 years of hurricane activity. Interestingly, there was a peak about 1000 AD that rivals and maybe exceeds recent levels.

The study validates the theory that two factors fuel higher hurricane activity: La Niña and high surface temperatures over the ocean. If climate change continues to warm ocean waters (and how can it not?) we will likely experience more active hurricane seasons. This year’s slow start is thanks to a newborn El Niño… though El Niño is changing too.
 

FACT:

Mother Jones was founded as a nonprofit in 1976 because we knew corporations and the wealthy wouldn’t fund the type of hard-hitting journalism we set out to do.

Today, reader support makes up about two-thirds of our budget, allows us to dig deep on stories that matter, and lets us keep our reporting free for everyone. If you value what you get from Mother Jones, please join us with a tax-deductible donation so we can keep on doing the type of journalism that 2018 demands.
