You better believe it Logic. If it actually warms, you all will reap great benefits. You think Vikings viked merely to vaction in warmer climes?
Nope, they went aviking because they had plenty of liesure time. Harvested early, and went exploring, gathering trinkets (loot) and even settled the western hemisphere. Think they called Greenland green as a joke?
If it hadn't been for the following mini-ice age(s) we might all be speaking Norse in this hemisphere. But the Viking settlements were too early and too far north to flourish when it turned cold.
The earth's climate is very cyclical. Witness Napoleon's retreat from Moscow. It was so cold ice crystals literally hung in the air. Cossacks froze to death mounted on their likewise frozen horses waiting to ambush the French. It was very very cold.
We've only been keeping detailed weather measurements for a few hundred years. Everything else is anectdotal and we really don't know what to expect next, despite what anyone wishes to claim.
And what is the major concern? That the seas will rise? And what part of nature will suffer the most? Mankind of course... because that's where we build most of our biggest cities.
