Lightning strikes in the far north could double by 2100. That means more wildfires, which could release massive amounts of planet-warming gas.
The Arctic isn’t doing so hot. That’s because it is, in fact, too hot. It’s warming at least twice as fast as the rest of the planet, which is setting off vicious feedback loops that accelerate change. Ice, for instance, is more reflective than soil, so when it melts, the region absorbs more solar energy. More dark vegetation is growing in northern lands, absorbing still more of the sun’s heat. And when permafrost thaws, it releases gobs of greenhouse gases, which further warm the climate.
The Arctic has gone
