Here is the latest from Guy McPherson, responding to a public attack on him
"A liar and a coward". I would say yes, based on my own interactions with a scientist locally who says much the same things as Mann does.
retired professor stated his misgivings privately to friends of mine
saying he did not think he could live in a world without glaciers
(he's a glaciologist). That didn't stop him from coming out of of
retirement to express the same things Michael Mann does - as aways
from an authoritative position without citing a single item to
support what he had to say.
I can clear my head sufficiently I will have more to say
Mann continues to promulgate the 2 C myth, and I know he knows better. Two degrees Celsius above the 1750 baseline is a political target dreamed into existence by neoclassical economist William Nordhaus. Mann ignores the United Nations upper limit of 1 C above the 1750 baseline, as well as the 0.5 C target-in-the-rearview-mirror acknowledged by climate writer and speaker David Spratt in October 2014 (links to all cited works are included here). In addition, as a leading voice for the politically motivated Intergovernmental Panel on Climate Change, Mann ignores important self-reinforcing feedback loops. He commits “errors” and omits facts.
“Some of the more egregious examples can be found among fringe characters such as ecologist Guy McPherson —- a doomist cult hero who insists that exponential climate change likely will render human beings and all other species extinct within 10 years.”
