Govt's need to raise the revenues they have lost since their tax cuts for the rich, and their very successful campaigns against the use of tobacco.
The problem with all other pollution issues surrounding the use of fossil fuels is that they logically call for BANNING or ISOLATION of those fuels, and reduced usage is the last thing that these govt's want.
So, provide scientists with enough money to make a lucrative career of chicanery, and keep the other 95% as added revenues, getting every instance of extreme weather, anywhere on the globe, on the six o'clock news, so that the population is bombarded into believing.
I think you can safely say, from Chuck's posts, and mine, on the use of petro-chemicals in the garden, that neither of us "pro-oil", or funded by fossil fuel companies, so that's the standard argument gone.
By the way, the Polar Ice Caps formed at an atmospheric CO2 level of 600ppm.
We've yet to reach 400ppm.
