This may be an influence in the particular case however it does not negate the effect of the main cause of global warming, the burning of fossil fuels. Global warming due to carbon monoxide in the atmosphere has been proven and is currently scientifically undisputed, kinda like smoking is the major, but not the only cause, of lung cancer.
Interesting cigarette companies paid a lot of money to a small group of doctors and researchers in their employ to say things like the link between cancer and smoking was still in dispute and had not been conclusively proven right up to the mid 1970's even though this link was proven in an undisputable way by the 1950's. Kinda like industrial and political stake holders are doing today with global warming. This despite the fact global warming has been undisputed in the academic community since the early 1990's.
