Has NOTHING to do with politics but EVERYTHING to do with MONEY...PERIOD.
Any scientific studies saying that there's global warming is detrimental to the Oil and Coal industry...which in turn costs them money. They want the monopoly on energy. Anything against them is bad for their bottom line. For decades they've funded bad science to prove that there's no such thing as global warming. Most of these studies are never submitted to pear-review publications.
Although there is one famous study a few years ago commissioned by the Billionaire Oil Barron Koch Brothers to prove once and for all that there isn't global warming. However the study back-fired on them. It actually proved that global warming does exist and that man is the major factor.
Even after their own study proving global warming does exist and it's mainly man made - the Koch brothers still deny it...WHY? Because they could loose BILLIONS if enough of the right people actually believed the truth.
But this isn't anything new with big money trying to disprove science. Go back to the 70's and 80's with Tobacco. The evidence that smoking was extremely unhealthy was overwhelming. But the Tobacco industry still commissioned their own studies of junk science to prove that not only wasn't smoking not bad for you, but it was actually beneficial. To this day there are people who don't believe that smoking is bad for you.
Go back even further to the coal industry. Black-lung disease was easily linked to mining coal and breathing in coal dust. But the coal industry fought tooth and nail saying it wasn't true. They even paid some doctor to say black-lung disease was a genetic disorder and had nothing to do with mining coal.
The only way it's political is that many radical conservatives are for BIG-BUSINESS and the biggest industry for decades in this country has been Oil and Coal. The rest of thinking America know the truth.
