Have the 1990 IPCC predictions been proved completely,
unarguably and utterly wrong? Yes. They predicted that if our
emissions stayed the same, temperatures would rise by 0.3 C per
decade, and would be at the very least 0.2, and the most 0.5.
Even by the most generous rehash of the data, the highest rate
they can find is 0.18 C per decade which is likely an
overestimate, and in any case, is below the very least estimate,
despite the world’s emissions of CO2 continuing ever higher.
Climate Scientist Matthew England called that “very accurate”.
Since when did 0.18 = 0.3? (Shall we call it “climate maths”, or
just call it wrong?) The IPCC had a whole barn wall to aim at,
and a battalion of government funded gold plated AK-47s to hit
the target, but they still missed. The un-Skepticalscience page
uses a pea and thimble trick to argue the IPCC 1990 predictions
were right (“Lessons from Past Climate Predictions: IPCC FAR”).
As usual John Cooks site looks “technical” but uses complexity
to hide the way they redefine
