Beardy makes a good point.
we have to restrict ourselves to periods in history when mamnals and particularly humans have developed.
indeed, we know the planet won't just explode, what climate changers claim is simply that life as we know it and in many locations it exists won't be possible.
others maintain that the climate may well 'trip' and jump toba new stable state considerably altered from the last few thousand years
