"Siberia and Greenland - they are slowly changing from barren to fertile". ..... yep moggs, the loss of permafrost and land ice will enable Iceland, Greenland and Siberia to become farmlands again.... volcanic and peat soils grow good crops. while the equatorial and subtropical regions turn to dust and the islands disappear under water.
well thats one way to look at it. but now predictions are valid mate.... wait and see what eventuates.
