The Internet is all abuzz with Hansen’s not yet failed (and previously ignored) 1981 forecasts.
The 1981 forecasts were of course superseded by his already failed 1988 Congressional forecasts, but the team is getting desperate to buy time. The graph below shows that his 1988 forecasts are already a total bust.
The next graph overlays Hansen’s 1988 forecasts (blue) on his 1981 forecasts. Sometime between 1981 and 1998, he completely lost the plot.
When the team isn’t busy rewriting history, they get busy hiding it.
