I think that is the key point. People should also realise that places that are currently green further south may well become desert - this doesn't mean more green it means green further North. It seems to confirm predictions that the "Wheat belt" may move North from the contiguous USA and central Europe to Siberia, Northern Europe, Canada, and eventually possibly Alaska.
It's the blind faith in speculation of things that may happen that just disturb me, and probably should disturb any logical thinking person.
Just like the guy above in Alaska citing anecdotal evidence that the presence of earthworms in mum's garden and the forest line increasing, no one can definitively prove that a localized warming cycle is part of a part of a multi-millennial trend. Since there have only been accurate thermometers measuring data for a couple hundred years, one could easily conclude there is too small of a sample of temperature data being presented. At best, climate change illustrates a trend of a small sample space, and it worst it represents a political bold-faced lie.
Sorry, but the unprovable mays that you present are equally as likely as donkeys flying out of my ass.
