It’s that dastardly gas CO2, doing its nefarious job of encouraging more and faster plant growth. Perhaps helping the planet Earth to self-adapt in advance of a coming mini-ice age in the lower latitudess.
This gas must be found and capped at the source!
I have read a ton on this, specifically the cooling / drying cycle versus the warming / wet cycle. When I read repeatedly that Global Warming will cause deserts to expand I find how ignorant / bias the reporter is or that the scientist that makes the statement has funding issues tied to research (they ignore all the climate records from the last 25,000 years). Each time the globe cools, the deserts expand (very quickly), each time it warms, the deserts shrink. Cold air has very little capacity to hold water (hence Antarctica is essentially a vast desert) and warm air can hold a lot.
