2. As you said in another thread, we're into a Cat. 5 Climate Emergency

I think that's a very reasonable way of looking at what's happening now.

It seems that the tipping point into irreversible and rapidly deteriorating climate change has arrived. A bit ahead of schedule, but never mind.

The question on the table is, "Now what?" It's not going to be a short-term emergency, this probably marks a permanent shift to a new, much less benign climate regime. It's going to impact the Northern Hemisphere's food and water supplies quite hard, starting now and continuing on into the foreseeable future. It seems to me that we're going to have to undertake extremely rapid and severe adaptation measures.
