The US Will See 50 Percent More Lightning Strikes Thanks to Global Warming Mother Jones
By now we're familiar with some of the scarier potential impacts of climate change:
Floods,
fires, stronger
hurricanes,
violent conflicts. Well, here's a new one to add to your nightmares. Lightning strikes in the continental United States will increase roughly 12 percent for every degree Celsius of global warming, a
study published today in
Science finds. If warming continues unchecked, that could translate into a 50 percent increase in lightning by the end of the century—three strikes then for every two strikes now. (On average, there are currently about 25 million strikes per year.)
Does this mean an increase your odds of getting struck by lightning? Technically yes, I guess, but I wouldn't worry about that.
Instead, the increase matters because lightning strikes are the principle cause of wildfires, which are already predicted to become more severe due to global warming. In one 24-hour period in August,
lightning in Northern California started 34 wildfires. The study doesn't make any specific predictions about wildfire activity, but knowing about future lightning conditions is an important part of that equation.
And to those of us on the West Coast, that is a rather important factor. Range and wildfires destroy many millions of dollars here in property every year, more lightning means more fires.
