There are two principal triggers for wildfires — human ignition and lightning — and clim...

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 so bizarro that lightning—a warm-weather phenomenon most common in the t...

Lightning strikes could double in the Arctic this century, setting the tundra on fire Philip Kiefer © Provided by Popular Science Lightning strikes could double in the Arctic this century, setting the tundra on fire Over the course of 2019 and 2020, a handful of fires burned in the tundra of Siberia, releasing stores of carbon similar to the entire annual emissions of France. As the Arctic continues to warm, similar fires are likely to become more common: lighting, one of the few firestarters in the far north, is becoming more common. According to research published yesterd...

Lightning strikes are an extremely rare phenomenon in the Arctic Circle – but as the global climate has begun to warm, these events have become more common. Just in 2019, lighting hit 483 kilometers (300 miles) of the North Pole, the northernmost instance on record. New research suggests that the amount of lighting is destined to double in the coming decades. As reported in Nature Climate Change, researchers have modeled the occurrence of lightning strikes at higher latitudes and discovered that by the end of the century, these are expected to increase by about 100 percent. "We projected h...

A multipurpose amphibious aircraft releases water to extinguish a fire in in southern Siberia last year. (Russian Emergency Ministry Press Service via AP, File) PARIS (AFP) — Lightning strikes inside the Arctic circle may double this century, sparking widespread tundra fires and increasing the risk of setting off the carbon time bomb held within permafrost, new research showed Monday. The permafrost of North America and Siberia contains enough carbon dioxide to roughly double all the carbon currently in Earth’s atmosphere, and there are fears it will melt significantly as temperatures ris...
