There is a tendency to obsess on "which direction" the climate might be headed when it would seem to me the core issue is that:
"All forms of Climate Change will increase stress."
The ways that mankind deals with stress are:
1) Improve efficiency (relieving stress)
2) War (reduces the population, thus reducing stress)
3) Natural Causes (disease)
I'm sure we can think of more and dig deeper into these.
Ignore "which direction" things change. Many models suggest weather might change by region anyway, so the issue going forward is more about stress.
