The Maths of WUWT

A brilliant headline left uncorrected:

James Hansen’s climate forecast of 1988: a whopping 150% wrong

150% wrong!! Brilliant!
. Be increased according to the Hansen’s forecast, the temperature would have compared to the same level in the 1970s by 1.5 ° C. In truth, however, the temperature has increased by only 0.6 ° C.
It is apparent that the next to it by the Hansen group in 1988 modelled temperature prediction by about 150%. It is extremely regrettable that precisely this type of modelling of our politicians is still regarded as a reliable climate prediction.

Hmm perhaps they are comparing 0.6C to 1.5C

but then this is not true either this needs to be referenced to K

i.e. the error is 0.9K on a temperature of 288K - about 0.3% error

One should not forget of course:

Its snowing CO2 in the antarctic!!
