This is mostly about lack of rainfall and not temperature.
Climate change causes more extreme weather, that doesn't imply this summer will be one of the coolest for the next 100 years?
- ragebol 4y ago> This is mostly about lack of rainfall and not temperature. Higher temperature air has less capacity to carry water, 7% less for every degree Celcius IIRC. So there could very well be a link. EDIT: Nope, I had it completely backwards, which makes much more sense too. Colder = less capacity for water. I need a drink. Can't delete my misinformed comment unfortunately.
- pfdietz 4y agoWhat? Absolute humidity at saturation increases with temperature (at fixed pressure). At 100 C (and 1 bar), the air becomes entirely water vapor.
- ragebol 4y agoOops, I had it the wrong way around.
- Loudergood 4y agoThat is incredibly backwards. Which is why when the temperature drops the water literally comes out of the sky.
- ragebol 4y agoYep, you're are right, my bad.
- trashtester 4y agoGenerally, though, hotter weather means more water evaporates, and regardless of whether the air can hold more or less water, over time the same amount that goes up will come down, meaning total precipitation will increase as the earth gets warmer. That doesn't mean that this increase will be uniform. The rain may very well come in Sahara, Arabia or Central Asia.
- Tsukiortu 4y agoOwning up to mistakes is better than hiding them, IMO. I have much for respect for someone who can say yeah I messed up like you did than someone who deletes it (Even if you can't).
- ragebol 4y agoWell, I'd delete to remove the disinformation, not to hide my mistake. Effect is the same of course.
- _ph_ 4y agoRight. But still the expectations mostly are, that it might be, as warming continues. The only exception would be a failing of the gulf stream, which for central Europe would be a huge reset in temperatures with a more Canadian climate.
- bryanrasmussen 4y agomy understanding is more extreme weather with a definite tendency towards increasing heat.
