Garth Paltridge offers a solution to CSIRO climate scientists suffering from the “settled” syndrome

Letter to The Mercury published 18/3/15

Keeping quiet about the uncertainty of climate prediction has at last come back to bite the climate research community on its collective bottom.  The obvious question has finally been asked in public – namely, if the science behind disastrous climate change is so settled, why continue to spend money on it?  It is not surprising that CSIRO is now cutting the number of its staff involved in climate research.

May I suggest to the remaining staff that they might profitably spend their time attempting to disprove the theory of disastrous global warming rather than simply finding data to support it?  There is more than enough uncertainty about climate change to give them a very good chance of upsetting what must be one of the world’s greatest scientific applecarts.   Since the upsetting of applecarts is what scientists are paid to do, it shouldn’t be long before they are once again showered with money and roses.  Just think of it – massive reward simply by returning to a research philosophy fundamental to scientific progress.  It is known as scepticism.

Australian Academy of Science hides model failures, other rainfall predictions, feedbacks evidence

The Australian Academy of Science (AAAS) updated their “Science of Climate Change” document. It’s more glossy unscientific propaganda.

Garth Paltridge wonders in The Australian  if the Academy will come to regret it. As usual, it’s what they don’t say that matters. They don’t mention how badly the current models have failed, and they hide that climate models give contradictory rainfall projections and just cherry pick one that gives the answer they want. They repeat the meaningless argument that their models don’t “work” without CO2. Perhaps they should let the taxpaying voters know that their models don’t “work” with CO2 either? None of the models can explain what caused the Medieval or Roman warming when CO2 was “ideal”. They conceal that the model forecasts rely on assumptions of feedbacks that the empirical evidence shows are wrong.

“Basically the Academy has fallen into the trap of being no more than a conduit for a massive international political campaign ”

Professor points out, it’s a less-than-nobel consensus

Garth Paltridge is an Australian atmospheric physicist with 45 years experience. He worked with CSIRO, the WMO, NOAA, and as Professor and Director of the Institute of Antarctic and Southern Oceans Studies. He has explained why he’s skeptical of the theory of man-made global warming in his book –  The Climate Caper: Facts and Fallacies of Global Warming. Here he explains how a scientific “consensus” can be bought. There’s more than one good reason why argument-from-authority is a fallacy. — Jo

Guest Post by Garth Paltridge

We hear that Julia Gillard is happy to have the CSIRO, the Bureau of Meteorology and the Australian Academy of Science on her side while making her arguments for a carbon tax.   Well of course she is.  She and her predecessor bought them.  And bought them but good.  Over the last couple of years her Department of Climate Change (the DCC) gave them 27 million dollars in the form of research grants.   That pays a fair swag of the salaries of the CSIRO and Bureau climate scientists who make up the majority of all employed climate scientists in Australia.

Dessler 2010: How to call vast amounts of data “spurious”

This is part of the big PR game of publishing “papers.”

In the climate models, the critical hot spot is supposed to occur because (specific) humidity rises in the upper troposphere about 10km above the tropics. The weather balloons clearly show that temperatures are not rising as predicted, so it was not altogether surprising that when Garth Paltridge analyzed weather balloon results for humidity, and found that humidity was not rising as predicted either.

Indeed, he found specific humidity was falling, which was the opposite of what all the major climate models predicted and posed yet a another problem for the theory that a carbon-caused disaster is coming. He had a great deal of trouble getting published in the first place, but once he finally did get published and skeptics were starting to quote “Paltridge 2009″, clearly, Team AGW needed an answer.  “Dessler 2010″ is transparently supposed to be that answer.

To start by putting things into perspective, lets consider just how “spuriously” small, patchy and insubstantial the radiosonde measurements have been. According to NOAA The integrated Global Radiosonde Archive contains more than 28 million soundings, from roughly 1250 stations.

Is science a rigorous skill or just rote specialties?

Prof Garth Paltridge released Climate Caper a year ago. As a working atmospheric physicist, his description of the fall of modern science is as insightful as his descriptions of the physics of the climate.

One of the messages  that struck me was his point that it used to be seen as  imperative for scientists to not be too specialized; to work in different specialties.

He points out that the mandate to publish or perish has far reaching consequences. To sum up his argument: the survival of a research scientist now depends on their ability to produce multiple papers; this rewards people who dilute their work, focus on trivial non-problems, and in short–tackle anything but difficult issues and deep revolutions.

Because of the need for multiple publications, no institution today would employ a scientist who was trained in another area–the new researcher would require too much uptime before their publications began to roll.  So universities aim to find PhD grads who are an exact fit for the program.

(…aiming to find an exact fit, ensures) narrow-mindedness of scientific outlook, mediocrity  in research, and a scientific literature that is so vast and overladen with minute  of the unimportant, that [...]
