Warmth will worsen wet and dry extremes – Climate News

GR: This warning is worth repeating. It needs to reach the ears of the climate-change deniers whose willful ignorance is endangering all of us and all the creatures sharing this ride with us. Storms, floods, and droughts will get worse.

“Wet and dry extremes across the world will become more marked as the planet heats up, evidence from past climates shows.”

“Two US scientists have once again confirmed one of the oldest predictions of climate change: that those regions already wet will become wetter, while the arid zones will become drier.

“This time the reasoning comes not just from computer models of future climate, but also from the evidence of the past.

“Because the northern hemisphere will warm faster than the southern, the temperature difference will drive the planet’s rainbelts northwards, at least during the winter months. The tropics will become wetter, while the subtropics and the mid-latitudes will become drier, and this will be most noticeable in June, July and August.

“The predictions – made in the journal Science Advances – come from two researchers. Aaron Putnam is a glaciologist who studies ancient climates at the University of Maine. Wallace Broecker is an oceanographer at the Lamont-Doherty Earth Observatory of Columbia University, and one of the pioneers of climate research.” –Tim Radford (Learn more: Warmth will worsen wet and dry extremes – Climate News NetworkClimate News Network.)
