... man made or natural?
Those with Fossil Fuel interests mostly argue that global warming as a 'man made' phenomenon is not scientifically provable.
Back in the days when smoking causing cancer was not a proven scientific fact, the tobacco companies had a similar stance regarding cigarettes.
The problem is that the elite who made the Big Money out of tobacco are not bothered by their culpability in the destruction of countless lives - their wealthy homes and luxury lifestyles ensure they sleep well at night, every night.
Perhaps the Fossil Fuels Elite are banking on escaping to another planet? Somewhere out there in a Goldilocks Zone!?
