Future increases in Arctic lightning and fire risk for permafrost carbon

Nature Climate Change, Published online: 05 April 2021; doi:10.1038/s41558-021-01011-y

Changes in lightning activity are uncertain under climate change. The authors project that summer lightning in the Arctic is likely to more than double by the end of the century, with implications for lightning-strike tundra wildfires and associated carbon release from permafrost.
