“A robust result, consistent across climate model projections, is that higher precipitation extremes in warmer climates are very likely to occur.” — IPCC

“As the climate has warmed… heat waves are longer and hotter. Heavy rains and flooding are more frequent. In a wide swing between extremes, drought, too, is more intense and more widespread.” — Climate Communications

It’s a tough fact to get one’s head around. But a warming climate means that many regions will both experience more extreme droughts and more extreme floods. The cause for this new weather severity is that a warming planet produces higher rates of evaporation together with more intense atmospheric convection. Warmer air over land means that the moisture gets baked out of terrain, lakes and rivers faster. And this warming effect causes droughts to settle in more rapidly, to become more intense than we are used to, and to often…
