Climate scientists have now admitted they were wrong about man-made global warming and I don’t know whether to laugh or cry.
Not very wrong, you understand, just a bit wrong. Apparently the planet is still going to hell in a carbon-lined hand-cart, just more slowly.
A study in the journal Nature Geoscience says the world has warmed more slowly than had been forecast by computer models, which were “on the hot side” and overstated the impact of emissions. You don’t say.
Global average temperature has risen by about 0.9C since pre-industrial times but there was a slowdown in the rate of warming for 15 years before 2014.
Er, would that be the slowdown that was authoritatively said not to have happened because the computer models all said it was impossible for it to happen, because everyone knew that rising CO2 levels inescapably caused global temperatures to rise and anyone who said the evidence of the slowdown showed the entire theory was bunkum and hogwash was a “denier”?
Yes, it would.
“Myles Allen, professor of geosystem science at the University of Oxford and another author, said: ‘We haven’t seen that rapid acceleration in warming after 2000 that we see in the models. We haven’t seen that in the observations.’
“He added that the group of about a dozen computer models, produced by government institutes and universities around the world, had been assembled a decade ago ‘so it’s not that surprising that it’s starting to divert a little bit from observations’. Too many of the models used ‘were on the hot side’, meaning they forecast too much warming.”
Nevertheless, according to the study rapid reductions in emissions will still be required – but the world now has more time to make the changes.
But if the computer models were wrong, on what evidence do these scientists base any calculation of what reductions in emissions will be required? On what basis do they still maintain there is a need for any reductions at all?
According to Myles Allen, the group of about a dozen computer models, produced by government institutes and universities around the world, had been assembled a decade ago “so it’s not that surprising that it’s starting to divert a little bit from observations”.
Oh really? Why isn’t it surprising? The theory hasn’t changed: you know, the theory – sorry, not a theory but the unchallengeable and incontrovertible and inconvenient truth – that rising CO2 levels cause a rise in global temperature.
So what exactly was it that had been fed into the computer models a decade ago that caused them to fail to predict that rising CO2 levels would not continue to cause such a rise in global temperature – or to be more precise, that they would cause a slowdown for a few years? Does the theory itself have a break for R&R? Because such a slowdown was certainly not included in the catechism of anthropogenic global warming theory.
Well, it was just those darned pesky computers that screwed up, wasn’t it, and led those scientists astray. Not the scientists’ fault at all, was it.
The truth is rather different. As many of us have been saying since AGW theory was first invented in 1988, the idea that computer modelling could ever predict something as stupendously complex as climate change was always scientifically illiterate. Computers are only as good as the information that is fed into them. If you feed rubbish in, you get rubbish out. Fed inadequate information designed to prove AGW theory, the computers disgorged predictions that proved AGW theory.
The whole thing was a scam from start to finish. Will these Potemkin scientists ever admit that? Even now the Met Office, among others, is still trying to spin the data, as David Whitehouse reports here.
For the past three decades, AGW zealots have insisted that “the science is settled” (itself another piece of anti-science illiteracy). They not only denounced as “deniers” those who actually looked at the evidence and questioned the theory but also sought to ruin their reputations and careers.
Climate-related science has been corrupted by ideologically-bent grant-funding only given to projects designed to prove the theory; government policies have been catastrophically skewed to undermine energy production and screw the poor through fuel bills inflated to meet the costs dumped on energy production through an orthodoxy no-one in government had the intelligence or cojones to fight.
We have been the victims of junk science. Maybe the highly limited admission of error in this study will help blow down the whole rotten facade of pseudo-science and finally expose this charlatanry for the ideological con-trick that it is.
