Global Warming Fantasy

Ian Plimer is OBVIOUSLY a crackpot…

Ian Plimer in denial

Anything he says on the subject of Global Warming should be taken with a grain of salt. In my opinion he has a vested interest in wanting people to believe the “Corporate Spin” that CO2 production doesn’t hurt the environment. Why else would he so stubornly refuse to understand the data?


Errors in book

To appreciate the errors in Plimer’s book you don’t have to be a climate scientist. For example, take the measurement of the global average CO2 concentration in the atmosphere. This is obviously important, so scientists measure it with great care at many locations across the world.

Precision measurements have been made daily since 1958 at Mauna Loa Observatory in Hawaii, a mountain-top site with a clear airflow unaffected by local pollution. The data is in excellent agreement with ice cores from several sites in Antarctica and Greenland. Thousands of scientific papers have been written on the topic, hundreds of scientists are involved from many independent research groups.

Complete No Brainer

Plimer, however, writes that a simple home experiment indoors can show that in a week, CO2 can vary by 75 parts per million by volume, equal to about 40 years’ worth of change at the present rate. He thinks this “rings alarm bells” on the veracity of the Mauna Loa data, which shows a smoothly rising concentration.

While it is undoubtedly true that if you measure CO2 in your home it could vary by large amounts from day to day – depending, for example, on whether you have the windows open or closed, or how many people are in the house at the time – this is not the right way to measure a global average. That’s why scientists go to mountain-tops or Antarctica or to the isolated Cape Grimm on the Tasmanian coast rather than measuring CO2 in their living rooms.

Incredible as it may seem, this quality of argument is typical of the book. While the text is annotated profusely with footnotes and refers to papers in the top journals, thus giving it the veneer of scholarship, it is often the case that the cited articles do not support the text. Plimer repeatedly veers off to the climate sceptic’s journal of choice, the bottom-tier Energy and Environment, to advance all manner of absurd theories: for example, that CO2 concentrations actually have fallen since 1942.

Boing Boing.. Who's the Guppy?

Plimer believes “global warming” occurring on Mars, Triton, Jupiter and Pluto proves human emissions of CO2 don’t affect Earth’s climate. He believes that once CO2 levels reached 200ppmv (about half of today’s value) the CO2 had absorbed almost all the infrared energy it could, and further increases will not have much effect. He believes global warming does not lead to biological stress. He believes volcanoes emit significant quantities of chlorofluorocarbons. He believes the sun formed on the collapsed core of a supernova. All these ideas are so wrong as to be laughable: they do not offer an “alternative scientific perspective”.

I saw a rabbit go down a hole..

Plimer probably didn’t expect an astronomer to review his book. I couldn’t help noticing on page120 an almost word-for-word reproduction of the abstract from a well-known loony paper entitled “The Sun is a plasma diffuser that sorts atoms by mass”. This paper argues that the sun isn’t composed of 98 per cent hydrogen and helium, as astronomers have confirmed through a century of observation and theory, but is instead similar in composition to a meteorite.
