physics

In a previous post on peacelegacy.org,I used the example of a chappie called Fred to show you why the absence of an atmospheric hotspot is, all by itself, a complete disproof of the hypothesis of dangerous anthropogenic global warming (AGW). For those who came in late, the entire basis for the AGW claim is that certain unverified, and now falsified, computer models predict a lot of warming over the coming 100 years. It is shocking, but true, that there is no actual evidence whatsoever for this idea; it is computer models alone, and those models are basically no more than coded guesswork. And what do these models predict?

They predict that the world is heated by the appearance of a 'hotspot' in the atmosphere above the equator.

Model predicts air above the tropics heats up. from the NIPCC Report p. 107
But the reality is that this hotspot has failed to develop:

I see they're going to fire up the Large Hadron Collider at half power. For those who haven't been following this story, your life is being put at risk.

The Large Hadron Collider (LHC) is a project by The European Organization for Nuclear Research, known as CERN. Back in 1964, a physicist called Peter Higgs found an elegant mathematical theory by which he explained one of the great puzzles of particle physics, why mass exists.

There is some background to this question. The twentieth century produced two great theories of physics: relativity and quantum mechanics. Quantum mechanics explained many curious puzzles in the subatomic realm, for example, why atoms don't collapse. Atoms have a field of electrons orbiting the nucleus; according to classical mechanics, any accelerating charged particle (like an electron orbiting an atom) should radiate energy. This means the electron should spiral into the nucleus and the atom should collapse. Obviously they don't because we are still here, made of functioning atoms! Another example is the radiation from black bodies. Only quantum theory can explain why the spectrum is what it is.

It is no exaggeration to say that the modern world only exists because of quantum mechanics: every piece of electronics that exists only works because of quantum mechanics, and a great deal of it was only discovered because we understood the theory behind it all. It is the most successful scientific theory ever. It has passed every experimental test ever thrown at it. But it doesn't explain gravity.

This is a reasonably short work, very different from Ian Plimer's Heaven and Earth. Although Paltridge is an atmospheric physicist and erstwhile Chief Research Scientist with Australia's CSIRO, he has put together an accessible summary of some of the damning evidence against the global warming alarmism.
