Climate Change Brews An Extinction Paradox


Climate change could trigger boom-and-bust population cycles making animal species more vulnerable to extinction. Environmental conditions that produce abundant supplies of food and stimulate population booms set the stage for population crashes that occur when several good years in a row are followed by a bad year. “It’s almost paradoxical, because you’d think a large population would be better off, but it turns out they’re more vulnerable to a drop in resources,” says Christopher C. Wilmers of the University of California, Santa Cruz, as reported by EurekAlert. Wilmers’ powerful new mathematical model evaluates how climate and resources interact with populations, finding that dramatic population fluctuations make species more vulnerable to extinction due to disease, inbreeding, and other causes, with each crash reducing the genetic diversity of a species, lowering its ability to adapt and making it more prone to extinction. —Julia Whitty

THANK YOU.

We recently wrapped up the crowdfunding campaign for our ambitious Mother Jones Corruption Project, and it was a smashing success. About 10,364 readers pitched in with donations averaging $45, and together they contributed about $467,374 toward our $500,000 goal.

That's amazing. We still have donations from letters we sent in the mail coming back to us, so we're on pace to hit—if not exceed—that goal. Thank you so much. We'll keep you posted here as the project ramps up, and you can join the hundreds of readers who have alerted us to corruption to dig into.
