Climate Change Denial in the Age of Trump | MICHAEL E. MANN
In the (now deleted) 2009 “Copenhagen Diagnosis” authored by such prestigious climate scientists as Michael Mann and Steven Schneider, they showed a sharp decline in Arctic sea ice from the 1960s through 2008, and predicted an ice-free Arctic by 2040.
I updated their graph with the latest data showing that the trend in Arctic sea ice over the past 14 years has flatlined.
The Arctic sea ice minimum is up nearly 50% from 2012.

Their prediction is failing badly, as is their representation of the past. They show a sharp drop in sea ice in the decade prior to 1979.
But the 1990 and 1995 IPCC reports show the exact opposite.
And the 1985 DOE report showed that extent during the 1950s was much lower than the 1970s.
Projecting the climatic effects of increasing carbon dioxide
This is standard practice for Michael Mann – misrepresenting the past and mispredicting the future.
