Complaint to Ofcom Regarding The Great Global Warming Swindle

2. Complete Transcript and Rebuttal

This, along with other evidence ( [IPCC]), led the IPCC in 2001 to conclude that most of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations ( [IPCC]), and to upgrade the certainty level to very likely in the 2007 IPCC report ( (PDF) [IPCC]).]

[Dr Tim Ball]

The analogy I use, is like, my cars not working very well, so Im gonna ignore the engine which is the Sun, and Im gonna ignore the transmission, which is the water vapour; and Im gonna look at one nut on the right rear wheel, which is the human produced CO2 – it, its that, the science is that bad.

[Prof Ian Clark]

If you havent understood the climate system, if you havent understood all the components, the cosmic rays, the solar, the CO2, the water vapour, the clouds and put it all together, if you havent got all that, then your model isnt worth anything.

[Comment 91: In fact, climate models do incorporate solar variability, as well as water vapour, clouds, aerosols, and a large number of other influences on the climate (see Comment 55, page 50). Tim Ball and Ian Clark must be well aware of this fact, so they are apparently setting out to mislead the public with the above statements.

Ironically, it is the graphs that this programme used to show a direct one-to-one relationship between solar activity and climate (see Comment 59, page 53 and Comment 64, page 59) which fail to take any account of aerosols or any of the many other influences on climate. Those graphs try to pretend that climate could possibly be influenced entirely by cosmic rays levels, driven by solar activity. For if there is more than one influence on climate, then by definition there could not be any overwhelming correlation between temperature and any one of the influences.]

The range of climate forecasts, varies greatly. These variations are produced by subtly altering the assumptions upon which the models are based.

[Prof Carl Wunsch]

The runs are so complicated you can often adjust them in such a way that they do something very exciting.

[Prof Ian Clark]

Ive worked with modellers, Ive done modelling; and, with a mathematical model, and you tweak parameters, you can model anything, you can make it warmer, you can make it get colder by changing things.
