2021 North American heatwave amplified by climate change-driven nonlinear interactions

Nature Climate Change, Published online: 24 November 2022; doi:10.1038/s41558-022-01520-4

The North American Pacific Northwest experienced an unprecedented heatwave in summer 2021. This study shows that atmospheric circulation features and regional soil dryness both amplified the event's severity; future warming increases the chance of an equivalent or stronger event.
