"How will fire frequency change in a world where the climate is getting warmer? Where dry places will get even less rain?" NASA asks in another video released this week. "Climate projections show that the drying trend in the United States will continue. There will be a greater risk of fire by the end of the 21st century in places that aren't prone to burning now, like the Great Plains and upper Midwest…That means more homes at risk, more federal dollars spent on rebuilding, a greater risk to the nation's food supply."
What's the answer? The space agency suggests that if humanity can somehow negotiate the financial, political, and other obstacles that lie in the way, we can slow the pace of the spread of "fire weather."
"If we reduce our greenhouse gas emissions, can we mitigate these risks?" NASA asks. "Under a low-carbon scenario, temperatures rise by 4.5 degrees. But under a high-carbon scenario, temperatures rise by 8 degrees. Either way means more fires, but…higher temperatures mean more burn scars."
Here's that video:
