Funny: I saw the Dark Ages Cold Period listed 300-700 CE. Looks like the droughts were starting about the time the Cold Period was ending, at least in Europe. Wouldn't a WARM period more likely lead to droughts, too?
And aren't you supposing a lot about what's going on in an industrial world based on what happened in a far more sparsely-populated, PRE-industrial world? Does huamn activity even factor in to your beliefs?
Many local droughts and climate change periods have occurred all over the world throughout human civilization. They're not particularly relevant to whether humans cause warming or not.
No, warmer periods usually have more precipitation. Colder periods have more drought. It's a function of ocean evaporation.
We were speaking of the demise of the Maya. I stated that the end of the dominant culture coincided with the Dark Ages Cold Period.
Man can and does impact his local area. Just build a large city with lots of concrete and you will raise the temperature. Put in a hydro dam and inundate a valley and you will impact the local climate. Deforestation does the same thing.
