Intensifying Climate ‘Whiplash’ Set the Stage for Devastating California Fires

The devastating wildfires that have ravaged Southern California erupted following a stark shift from wet weather to extremely dry weather — a phenomenon scientists describe as “hydroclimate whiplash.”

New research shows these abrupt wet-to-dry and dry-to-wet swings, which can worsen wildfires, flooding and other hazards, are growing more frequent and intense because of human-caused climate change.
