How is climate change increasing the risk of heavy rainfall? It’s basic physics: warmer air holds more water vapour. So when a storm comes along today, there’s a lot more of it available for that storm to sweep up and dump than there was 50 or 100 years ago. A LOT.

And warmer air and warmer water leads to more evaporation => more water that will fall down as rain somewhere.

Indeed. But warmer air is only the smaller part of the reason. The big part is warmer oceans. Warmer oceans contain more energy and can form much bigger storm clouds much faster. Instant hurricanes that didn’t even exist 2 days earlier can destroy cities a few hours later as Hurricane Otis did

A lot of people have trouble reconciling that with the *also* increased incidents of drought. But it's also simple: 1) A warmer climate also *dries out* terrain faster 2) Monsoon belts expand, making rainfall more seasonal (wet & dry extremes) 3) Less snowpack makes rivers more seasonal.

Also too, oceans are warmer so more evaporation as well

It’s ironic that basic physics is disregarded by climate change deniers who have no second thought about using technologies made possible by the same physics.

Anecdotal- over the last 18 months, daily humidity levels in Austin seem to be going up, I’m suspecting because the Gulf is hot. I have an incubator for neonatal kittens. It is regularly hitting internal humidity of 60%+ and the house hovers at 55-60 internal humidity. And I have central air!

Also helpful is the idea, that if the entire world has warmed up by about 1.5°c on average, the total evaporation taking place around the globe also increases significantly. And all of that water needs to find its way down sooner or later 🌧️⛈️🌨️

Looks like Bolsonaro's wholesale rape of the Amazon basin is paying dividends - and not in a good way, either.
