Blockbuster honesty: Expert modeler admits they can’t predict extreme events, El Nino, tipping points, rain or river flows

By Jo Nova

The science is settled, except when they need more money

Australia’s leading climate modeler wants a big new Climate Agency, and to make the case he admits the current models really can’t predict if rivers will rise or fall, if Antarctica will get bigger or smaller, if sea levels will rise much, or if El Ninos or La Nina will be more common or if the floods of Lismore will occur more often.

To give us some idea of how bad the current models are, he’s recommending we shift from models with 100 kilometer blocks to high resolution models with 1 km cells. These new models will be at least 10,000 times bigger than current ones, and if they increase the vertical slices, they could easily be one hundred thousand or even a million times bigger.

And if they get this super model, they’ll need 10,000 to one million times the energy. But now that we’ve wrecked the grid, good luck running those monster data centers off sunlight and breezes.

Bet the world, but not my superannuation on our climate models says modeler Prof Andy Pitman

By Jo Nova Warn the bankers, our climate models are not something to invest in say the modelers

A group of top climate modelers have come together to warn bankers that climate models are wonderful but basically useless for predicting things that financial models need — like the trends in the hottest, wettest or windiest weather in any city on Earth. Often the expert models can’t even agree on the sign. Will it get bigger or smaller? It’s that bad.

The raw truth of just how unskilled these models are is laid bare in the graphs. The modeling team chose London, Mumbai, New York and Beijing and picked the nearest 100km x 100km “square” on the map. They ran about 37 models on 3 scenarios and achieved something that looks like a painting done with a jet engine.

The modelers can’t say if the hottest maximums in Beijing will get hotter. Even if the world warms 2 degrees (by random happenstance), Beijing’s hottest-days might actually get cooler. The rainiest days of the year could be more extreme unless they’re less extreme. And the windiest days will definitely be stronger, weaker, or about the same. Get it?

The quote of the […]

Figure this: Andy Pitman says “we don’t understand what causes droughts” but “the indirect link is clear”!

Back in August I posted the extraordinary first quotes from Prof Andy Pitman that there was no link between climate change and drought.

Prof Andy Pitman, Climate Modeler, UNSW

The news about droughts was banal and obvious, because more water evaporates in a warmer world, and therefore, more rain falls — how could it be any other way? What goes up, must come down. But that quote was very important because it had never been stated so unequivocally by a high ranking believer and modeler. (Thanks to Jim Sternhill for spotting this incendiary and unwittingly honest quote.) Since being posted here, those quotes have been picked up by Maurice Newman, Alan Jones, then Chris Kenny (The Australian editor) and Andrew Bolt — which means the Pitman-drought-admission has become a major headache for the climate machine. Hence, they had to come up with some fogging excuse to muddy up the clarity, and here it is. Pitman forgot one word.

Prof Andy Pitman now says that he meant to say there was no direct link:

Barry said this “clarification” said Pitman had “left out a crucial word”: that “there is no direct link between climate change and drought”.

Prof Andy Pitman admits droughts are not worse and not linked to climate change

In June Professor Andy Pitman quietly dropped a bomb:

“…as far as the climate scientists know there is no link between climate change and drought.”

“…there is no reason a priori why climate change should made the landscape more arid.“

He’s admitting there’s never been a scientific basis for the endless climate drought scares? He went on to say that in Australia, droughts are not increasing, and there’s no drying trend in one hundred years of data. He’s also admitting the models can’t predict extremes in rain either. Where are the press releases?

It’s great to hear him speaking like a skeptical scientist, with candor and care, but 52% of Australians (including many of our politicians) think “climate change” is already causing more frequent droughts. So half the country is not only convinced droughts are increasing, but they think climate change is causing an effect that isn’t happening. And the world is spending $330b a year on windmills and solar panels […]

Dr David Evans: Four fatal pieces of evidence

Dr David Evans lays out four crucial pieces of evidence, and calls for a debate with Prof Andrew Pitman. But the evidence is so unarguably strong for skeptics, we know that the name-calling-team-who-want-our-money will do anything to avoid a public debate. If the evidence is “overwhelming” why are they so unwilling to explain it? — Jo

Submission to the Inquiry into Carbon Tax Pricing Mechanisms

Dr David Evans

20 September 2011

Dr David Evans consulted full-time for the Australian Greenhouse Office from 1999 to 2005, and part-time to the Department of Climate Change from 2008 to 2010, modeling Australia’s carbon in plants, debris, mulch, soils, and forestry and agricultural products. Evans is a mathematician and engineer, with six university degrees including a PhD from Stanford University.

Global warming has become a scam. Let me explain how it works.

It has superficial plausibility. Yes, global warming is occurring. Yes, carbon dioxide is a greenhouse gas and levels are rising. And yes, every molecule of carbon dioxide we emit causes some global warming.

Many non-scientists think that proves the case, but it doesn’t. In particular, it doesn’t rule out the possibility that carbon dioxide is merely […]

Andrew Pitman cries poor and rich, says climate science is certain, but is new and “changing”

Well which way is it then?

Last year Professor Andrew Pitman said the science was settled, he was a poor volunteer, and skeptics were rich (which was why they were winning).

…climate scientists are losing the fight with climate sceptics. That the sceptics are so well funded, so well organized, have nothing else to do, they kind of don’t have day jobs, they can put all of their efforts into misinforming and miscommunicating climate science to the public, whereas the climate scientists have day jobs and this isn’t one of them. All of the efforts you do in an IPCC report is done out of hours, voluntarily, for no funding and no pay, whereas the sceptics are being funded to put out full scale misinformation campaigns…”

[Source: It was so bad, the ABC broadcast it, twice — Eleanor Hall interviews Andy Pitman. Robin Williams thought it was so “useful” he rebroadcast the same factually incorrect, irrelevant material.]

Tom Nelson caught him telling prospective students in the Adelaide Advertiser that they ought to rush to study climate science so they can get paid well, be political activists, and change our understanding of the climate.

Almost invariably, climate PhDs with a physics […]

Pitman: paid $190,000 a year to throw baseless insults

Last week a paid public servant spoke untruths, but instead of being exposed by the media, he was aided by our taxpayer-funded public broadcast network. Andy Pitman spoke about the socio-economic position of a group he avoids, and let down UNSW, abused the title “Professor”, and misled the public.

The journalists allowed the baseless smears to be broadcast without question, not just once, but twice.

Robin Williams thought it was so “useful” he rebroadcast the same factually incorrect, irrelevant material on his “science” show. Oops.

It’s hard to cram more anti-truths into one declaration:

“My personal view is that climate scientists are losing the fight with climate sceptics. That the sceptics are so well funded, so well organized, have nothing else to do, they kind of don’t have day jobs, they can put all of their efforts into misinforming and miscommunicating climate science to the public, whereas the climate scientists have day jobs and this isn’t one of them.
