More evaporation means more water vapor. More water vapor means more clouds. More clouds means more sunlight reflected back into space. More clouds means more rain. Turns out water vapor regulates itself pretty effectively. You might not have noticed this if you live somewhere where it doesn't rain much.

> Do you know what happens to a person whose body temperature is five degrees above or below normal? It's a medical emergency. It can even kill them.

Do you know how a greenhouse works? You put plants inside this big room made mostly of glass, and it gets really hot inside. Now what is a greenhouse for? What happens when you raise plants in a greenhouse? Do they die quickly from the higher temperature?

> Now please consider that a lot of life out there is used to fairly constant temperatures and lack any form of thermoregulation. A deviation of a few degrees will result in mass death and the destruction of entire ecosystems.

Fascinating. Good thing the earth isn't a human body.

Gee, it's also a good thing we don't have regular summers and winters every year, or everything would be dead by now from the constant excessive temperature changes every year.

When's the last time the temperature was up a few degrees for a long period? Oh yeah, the Medieval Warm Period. That time of worldwide devastation where people grew crops in Greenland and various northern European countries, and wine grapes grew in Britain, thanks to the horrible retreat of the arctic circle.

Evidence has been found of the Medieval Warm Period affecting Taiwan, China, and Japan as well. Ironically, a lot of that evidence was found in Kyoto.

It would be a disaster if the Brits started making wine again, given how awful most of their Haute British Cuisine turned out.
