A study suggests that in Mediterranean-like climates, the response of precipitation to climate warming is highly variable, with drying projected in the Mediterranean and Chile on a timescale faster than global-mean warming, and wetting projected in California that is delayed relative to global warming; the differences result from the existence of separate fast and slow sea-surface temperature responses to greenhouse gases that give rise to distinct regional changes in atmospheric circulation.
