About 8k years ago we came off of a global maximum (+1c), slowly declining back down. Because of C02 it seems we've brought this back up despite the global trend down.

The global trend should put us at about -5c in the next 10k years.

So perhaps some global warming is a good thing, to keep us at +1 or 2c. I recognize we've already seen an unexpected +3c shift in less than 100 years, so we're going at 7x the speed we should. But with that said:

What if some global warming is a really good thing?

Ah! Yes! Eight thousand+years ago when the Sahara Dessert, Gobi Dessert and Central Australia were forested, grass covered and filled with many lakes and rivers with abundant wild life. Climate change what a bummer!
