Climate change is forecast to burn Yosemite National Park violently in coming years. A new study in the International Journal of Wildland Fire finds the dwindling spring snowpack in the Sierra Nevada will exponentially increase the number of lightning-ignited fires.

The increase has two causes:

  • Increasing levels of carbon dioxide in the atmosphere appear to be leading to more lightning strikes.
  • Decreasing winter snowpack—conservative climate models predict a 17-percent fall by 2050—will allow more lightning strikes  to ignite fires in the park.

The BBC quotes lead author James Lutz of the U of Washington Seattle:

“People already expect more ignitions from hotter summers. But this research suggests that declines in snowpack will have an additional effect.”

In other words, a warming climate is setting up a nasty positive feedback loop, making a bad situation worse.

Come on, world leaders, lead already.

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.
