A spike in Arctic lightning strikes may be linked to climate change

Climate change may be sparking more lightning in the Arctic. Data from a worldwide network of lightning sensors suggest that the frequency of lightning strikes in the region has shot up over the last decade, researchers report online March 22 in Geophysical Research Letters. That may be because the Arctic, historically too cold to fuel many thunderstorms, is heating up twice as fast as the rest of the world ( SN: 8/2/19). The new analysis used observations from the World Wide Lightning Location Network, which has sensors across the globe that detect radio waves emitted by lightning bolts. Researchers tallied lightning strikes in the Arctic during the stormiest months of June, July and August from 2010 to 2020. The team counted everywhere above 65° N latitude, which cuts through the middle of Alaska, as the Arctic.

Arctic lightning strikes more likely as temperatures rise

Encountering a polar bear or being caught in a snowstorm are more pressing concerns. But new data shows that rising temperatures in the Arctic have significantly increased the probability of thunderstorms bubbling up, particularly during the summer months. Researchers used the World Wide Lightning Location Network to monitor lightning strikes occurring at latitudes above 65°N for the years 2010 to 2020. Their findings, published in Geophysical Research Letters, show the number of lightning strikes during the summer months tripled over this time period, from about 18,000 strikes in 2010 to more than 150,000 in 2020. Over the same time period Arctic temperatures increased by an average of 0.3C, creating more favourable conditions for intense sum
