[ale] unusual global warming experiment

I don't know if this is cool or crazy, but it is interesting either way.

They are going to surround a forest with plastic walls, then heat the
ground and air to simulate GW.  They will also increase the CO2
concentration.  Wait 10 or 15 years and see what happens.

Note that say they are doing it in Minnesota because the models
predict the biggest GW impact is there and to the north of there.
