Tim Ball - hardly impressive as a start.
Next, John Christy - now Christy is a genuine expert, albeit one who has made some mistakes. But what does he have to say? 'I've often heard it said that there is a consensus of thousands of scientists on the global warming issue, that humans are causing a catastrophic change to the climate system,' says John Christy, Professor and Director of the Earth System Science Center, NSSTC University of Alabama. 'Well I am one scientist, and there are many, that simply think that is not true.'
Disappointing - the old "catastrophe" strawman. Does Christy not engage with the causes, which is nominally what this prog is about. Most likely, though, they will just go for scattershotting stuff in the hope of confusing.
Then Eigil Friis-Christensen, fair enough, though hardly a world-leader. Clouds and cosmic rays, of course, and we'll neglect the lack of an 11-y solar cycle on any recent increase in solar.
And finally Ian Clark, Professor of Isotope hydrogeology and paleoclimatology at the Dept of Earth Sciences, University of Ottawa explains: Solar activity over the last hundred years, over the last several hundred years, correlates very nicely, on a decadal basis, with temperature. Well no it doesn't; and of course we don't have solar records anyway; but never mind.
So that seems to be it from the experts, unless they are waiting to spring out others as a surprise on the night.
Oh, I missed the experts in the film argue that increased CO2 levels are actually a result of temperature rises - gosh, are they really dumb enough to argue that CO2 isn't anthropogenic. Maybe they are - who knows."
With regards Christy and Strawman.
A "strawman argument" is when you pretend your opponent is saying something they aren't, then use it against them.
The strawman is this:
The consensus is that CO2 increase is causing the warming observed since the 1970s and that as the increase in CO2 is known to be due to humans, humans are causing the warming.
That is accepted by the vast majority of scientists qualified in the relevant fields.However what Christy referred to was catastrophe, and it's true, most scientists would be much more qualified in commenting on that and would
not say that we are going to have a disaster.
But that does not challenge the fact that almost all of the published science, and almost all of the relevantly qualified scientists do not challenge the theory that more CO2 means a warmer planet and that the signature of human CO2 emissions is clearly evident in the warming of the 20th century. So if you don't understand the science, but you don't believe in human driven global warming. What makes you think you know better than the scientists?
