Understanding
the link really comes down to one figure: the air can hold 7% more
water with every degree Celsius that the temperature rises. That figure
comes from the Clausius–Clapeyron equation, a widely accepted physical
law established centuries ago long before any politicized debate on
climate change.“A
warmer ocean makes a warmer atmosphere, a warmer atmosphere can hold
more moisture,” says Gabriel Vecchi, a professor of geosciences at
Princeton University who studies extreme weather events. “So, all other
things equal, the same storm in a warmer planet would give you more
rainfall.”
