Lightning strikes in the Arctic tripled from 2010 to 2020, a finding University of Washington researchers attribute to rising temperatures due to human-caused climate change. The results, researchers say, suggest Arctic residents in northern Russia, Canada, Europe, and Alaska need to prepare for the danger of more frequent lightning strikes.The study, published March 22 in Geophysical Research Letters, used data from the UW-based World Wide Lightning Location Network to map lightning strikes across the globe from 2010 to 2020. WWLLN sensors detect the short burst of radio waves emitted during a lightning strike.
