Does he mean the CFACT billboards?
From the transcript of James Hansen’s testimony before the House of Commons:
Q9 Zac Goldsmith: Just on the politics of that, which I would be interested to know. There is a report in The Guardian today saying that according to an assessment of all the scientific papers on climate change, where there is a verdict on whether we are responsible or not, more than 99% seem to be of the firm view, which Professor Hansen takes, that we are very much the dominant force for the changes that we are seeing. There is as close to a scientific consensus as science allows. It is hard to hope for or imagine a stronger consensus.
Despite that, politically there seems to be a roll-back. There are very many senior political figures, in this country and elsewhere, who are reluctant to embark on any kind of policy journey that would adequately address this issue. Professor Hansen, I am interested to know how much dialogue you have had with climate-sceptical politicians, either in Europe or in the States, and also climate-sceptic scientists. How much exchange do you have with the people who take that view?
Professor Hansen: That is a good question because I think that that dialogue is really important. I can specifically comment on the situation in the United States, but I think it is very analogous to the one in the United Kingdom. I have taken some initiative to speak with conservatives in the United States. A large fraction of our members of the Republican Party, which is the more conservative party, have taken the position that this whole climate thing is a hoax, and, because of the huge amount of advertisement in the media, have even convinced a fraction of the public-perhaps a quarter or a third-that this is all a hoax dreamed up by scientists who want to get research funding, which is, of course, silly.
Conservatives historically in the United States have been the party that has introduced extremely important legislation for environmental protection and for conservation of public lands, going all the way back to Teddy Roosevelt a century ago. The thoughtful conservatives know that of course this is not a hoax, and eventually it is going to be clear. If a party continues to be anti-science and pretends that it is a hoax, once it becomes clear it was not a hoax, then the consequences are likely to be that the public demands the Government solves the problem and then the Government takes over. That is the worst possible outcome from a conservative’s point of view. They don’t want the Government taking over, so- [Emphasis added]
