From the wiki document:
The IPCC was one of the main targets of the documentary. In response to the programme's broadcast, John T. Houghton (co-chair IPCC Scientific Assessment working group 1988-2002) assessed some of its main assertions and conclusions. According to Houghton the program was "a mixture of truth, half truth and falsehood put together with the sole purpose of discrediting the science of global warming", which he noted had been endorsed by the scientific community including the Academies of Science of the major industrialized countries plus China, India and Brazil) along with the IPCC. Houghton rejected claims that observed changes in global average temperature are within the range of natural climate variability or that solar influences are the main driver; that the troposphere is warming less than the surface; that volcanic eruptions emit more carbon dioxide than fossil fuel burning; that climate models are too complex and uncertain to provide useful projections of climate change; and that IPCC processes were biased. Houghton acknowledges that ice core samples show CO2 driven by temperature, but then writes that the programmes assertion that "this correlation has been presented as the main evidence for global warming by the IPCC [is] NOT TRUE. For instance, I often show that diagram in my lectures on climate change but always make the point that it gives no proof of global warming due to increased carbon dioxide."[3]
So he's agreeing that CO2 is driven by temperature and not the other way around, just like the program claimed. If co2 levels follows temperature ... uhm... how is co2 emissions caused global warming. Makes little sense.
Yes the program is one sided, yes it seems data was incorrect. But even if his points aren't valid, that does not make the theory of human caused global warming due to co2 emissions valid!
It's quite simple really. Just show evidence that human caused emission of co2 is causing global warming, and the debate ends.
