Climate scientists still puzzle about the rapidity of aridification and the climate processes that led to this.

Although the high - latitude cooling probably did not act alone in driving the aridification, it seems to be have been the missing piece in the puzzle and acted to set the aridification process in motion.

«For that, perhaps the best available term is aridification, which describes a period of transition to an increasingly water - scarce environment — an evolving new baseline around which future extreme events (droughts and floods) will occur.»

An ensemble of climate model simulations reveals that limiting anthropogenic warming to 1.5 °C instead of 2 °C can markedly reduce the area undergoing, and thus the population exposed to, aridification.
