Prolonged droughts, wildfires and water shortages. Torrential downpours that overwhelm dams and cause catastrophic flooding.

That led to heavy vegetation growth that provided fuel for the devastating January wildfires in Los Angeles after drought returned. But how can global warming cause both drier and wetter extremes? Here’s what experts say.
