A "warming of several degrees Celsius" = the end of life as we know it.But what about temperatures?
While some deniers/delayers/inactivists, like MIT's Richard Lindzen, have argued that negative feedbacks dominate the climate -- all of the evidence points to amplifying feedbacks dominating (except the one negative feedback that the deniers fiercely fight, discussed below).
That was a key point of this post: In the real world, key climate change impacts -- sea-ice loss, ice-sheet melting, desertification, and sea-level rise -- all are either near the top or actually in excess of their values as predicted by the IPCC's climate models.
