I\'m curious as the whether methane has been included in the model, and in particular the methane that may be released by microbial activity from peaty permafrost if it melts. If not, is this an issue for it\'s ability to accurately predict future climate, and is it likely to be included in future editions.

On a similar note, is vegetation cover/clearance and it\'s effect on things like dust in the atmosphere included or will it be included in future?

Make you wonder how slow the model will eventually become!
