The same geniuses who forecast a mild winter the last two years (and a few barbecue summers) warn that the tropics can’t handle warm weather.
A “largely ice free Arctic summer” is ludicrous. Even if you believe that the Arctic could be ice free at the Autumn equinox, believing in an ice-free July is beyond stupid. The map below shows the record low extent from July 15, 2007.
With the tundra becoming unfrozen it would increase the biological activity in the region and also would allow farming in very rich soil.
They have already decided the tropic dryness was a farce with Amazongate. They are showing regions that would receive more rain in a warmer climate and claiming drought conditions. They must think everyone is as dumb as they seem to be.
