From the abstract: In the early twenty-first century, satellite-derived tropospheric warming trends were generally smaller than trends estimated from a large multi-model ensemble.
The problem is the models on which the global warming scare is based were simply wrong:
We conclude that model overestimation of tropospheric warming in the early twenty-first century is partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations.
James Delingpole describes Santer's colorful history in the climate wars since he was outed in the Climategate scandal.
Sceptical scientists identified this problem years ago: John Christy, who collects satellite temperature data out of the University of Alabama-Huntsville, has testified before Congress on the failure of models to predict recent global warming.
Christy’s research has shown climate models show 2.5 times more warming in the bulk atmosphere than satellites and weather balloons have observed.
I can think of a number of reasons why there are warming alarmists - stupidity, dishonesty and a knowledge of history that goes no further than what they had last time they visited Maccas. Does anyone know any others?
One question no warming alarmist has ever been able to answer: Why was there a Second Ice Age?
The answer is: Because the First Ice Age finished. Otherwise, we would still be in it, and you couldn't have a second one before the first finished.
Corollary: How many coal-fired power stations, industrial plants, aeroplanes, trains, automobiles, and microwave ovens were in existence at the time to cause the obvious global warming that brought the First Ice Age to an end?
Answer: If you really need me to tell you that, then check out which of the categories I enumerated above do you belong to? I mean, are you stupid, dishonest, or completely ignorant of history?
