The vast imprecision of IPCC "science" renders it absurd

By geologist Marc Hendrickx, commenting from Australia

ABC Unleashed’s favourite psychologist Stephan Lewandowsky once again takes aim at those suggesting it might be prudent to wait for the facts to come in, before turning society on its head. All to combat a climate crisis that has been manufactured up by activists with a poor appreciation of what constitutes a hazard; generally inner city folk. [In Australia, inner city areas tend to be prestigious, due to the lack of crime-prone minorities]

This time round in a piece titled “Climate change: are you willing to take the risk?” Lewandowsky suggests the level of certainty in climate science is similar to other well founded scientific principles like gravity. He contends that if climate science has the same veracity as evolution for example, who wouldn’t be prepared to sell their children and prepare for climate Armageddon? However, if we apply the same level of uncertainty inherent in climate science concepts to other disciplines it seems there is little to justify Lewandowsky’s level of confidence.

If IPCC Climate scientists were Physicists: The IPCC has found that the total net anthropogenic forcing is 1.6 W.m-2 with an error range of 0.6 to 2.4 W.m-2. If the IPCC’s same errors for Radiative Forcing Components were applied to the universal gravitational constant, IPCC climate scientists would tell us that the UGC is 6.67 × 10-11 N·m2/kg2 with a range of 2.5-10 N·m2/kg2. They would then assure us there is 90% certainty that acceleration due to gravity on Earth at sea level is in the range 3.7 to 14.7 m.s-2. IPCC climate scientists would tell us apples may be as light as a feather or as heavy as a brick. They would tell us apples fall down, but they’d be unable to tell us how fast, and occasionally they may actually fall upwards. As a result of their endeavours, Newtonian physics and Relativity would be tossed on its head. Quantum physics, built on the uncertainty principal, would have no place in a world where the science is settled. Speaking about gravity IPCC climate scientists would say things like: "The fact is that we can't account for the lack of gravity at the moment and it is a travesty that we can't." They would earnestly explain that there was no statistically significant gravity from 1995, and suggest that anyone disagreeing with their assessment must be a gravity denier.

If IPCC Climate Scientists were engineers: If IPCC climate scientists were engineers they wouldn’t use rulers to measure distance, they’d use the wind. IPCC climate models predict a hot-spot over the tropics but thermometers attached to weather balloons show no sign of it, the hotspot is missing. So with no warming in the thermometers IPCC climate modelers looked elsewhere and claimed to have found it in wind shear. Throw away your calculators, they would tell the engineers the answer is blowing in the wind. So how would IPCC climate scientists go at engineering? Early attempts at engineering by IPCC climate scientists are documented in the image to accompany this piece above; the effect of wind shear not accounted for in this case: Would you trust an IPCC climate scientist to build your building?

If IPCC Climate scientists were laser eye surgeons. In a report titled "Draft Water Sharing Plan Greater Metropolitan Region unregulated river water sources.", the NSW Office of Water has forecast rainfall and runoff across NSW using 15 global climate models for the IPCC SRES A1B climate scenario; finding:

For the Greater Metropolitan Region the worst case forecast is a 5-10 per cent reduction in mean annual rainfall by 2030, while the best case is a 5-10 per cent increase in mean annual rainfall. 7 of 15 models predict that mean annual rainfall would decrease by between 2 and 10 per cent, while 8 of 15 models predict that rainfall would increase by between 2 and 10 per cent by 2030.

Half of these models are wrong! What other science happily promotes incorrect models and expects politicians to make decisions based on spurious outputs? And Lewandowsky suggests that IPCC climate science has the same precision as laser surgery!

Applying the same laser like precision of the climate models to eye surgery in 7 out of 15 cases IPCC climate scientists as laser surgeons would blind the left eye, while in 8 out of 15 cases they would blind the right.

If IPCC climate scientists were historians. The palaeo-temperature study that gave the world the Hockey Stick Graph has now been debunked so many times that even the Australian Academy of Sciences concedes the existence of the Medieval Warm Period and Little Ice Age. Based on the mess they made of the last 1000 years of climate, if IPCC climate scientists were historians they’d find no evidence for the French and Russian Revolutions. Copernicus, Galileo and Einstein would be cast into the dustbin denounced as deniers of prevailing authority. They would ignore Napoleon’s defeat in Russia because the weather could never have been so cold in the 19th century. There’d be no Renaissance, the authorities would not allow it. Aristotelian philosophy would rule supreme over the scientific method. If IPCC climate scientists were historians, history would only record those events officially sanctioned by governments, queen and kings. Only those facts that supported the prevailing view would be recorded for posterity; inconvenient truths have no place in the official accounts. Thankfully IPCC climate scientists are hopeless at history.

If IPCC Climate scientists were climate scientists: With current warming trends at about 0.1 degrees C per decade, well short of the warming required to lend credence to IPCC climate models that forecast rates of 0.3 to 0.7 degrees C per decade it seems climate scientists are not even capable of doing their own job let alone anyone else’s.

And if IPCC climate scientists were fruit pickers: they would obviously pick the cherry. They appear so used to cherry picking data to fit the models there simply is no other fruit, except perhaps the Durian, which is a nice metaphor for the current state of the IPCC.

IPCC science: are you willing to take the risk?
