A study recently published in the journal Geophysical Research Letters finds that Arctic lightning has tripled in the last decade alone. The data suggests that the total number of Arctic lightning strokes has risen sharply since 2010. Next, the researchers compared the rate of Arctic lightning strokes with lightning around the rest of the world. They found that the fraction of Arctic lightning compared with global lightning tripled between 2010 and 2020. Nature recently reported that at least one other global lightning detection network has not recorded the same increase in Arctic lightning, although its records only extend back to 2012.
