It is possible/plausible that the sensitivity of the climate is on the low end of the IPCC envelope (1.0-1.5C), with a slow creep of warming superimposed on much larger natural variability.
It is possible/plausible that the IPCC projections are actually correct (right for the wrong reasons; too much wrong with the climate models for much credibility, IMO).
It is possible that AGW and natural variability could conspire to cause catastrophic outcomes

A great synthesis very useful and impressive, well argued. From 1998 until today.

Professor Michael Mann, inventor of the climate Hockey Stick, has just shamelessly shifted the dreaded climate tipping point to 2020.
Until recently Mann claimed 2016/17 was a climate tipping point.
