Arctic Lightning Up 300% in One 11-Year Study (EOS)
Holzworth and his collaborators found that the fraction of lightning occurring in the Arctic increased from roughly 0.2% in 2010 to a little over 0.6% in 2020. That threefold increase is significant, the researchers suggest, and might be tied to warming temperatures in the Arctic. Global temperatures have been climbing in the past few decades, and the Arctic is warming even faster than other parts of the planet. When Holzworth and his colleagues graphed their dimensionless parameter versus the global temperature anomaly, they found a linear correlation.
