The BIG question about Man causing Global Warming that nobody can answer without sticking their foot in their mouth.
How did the last Ice Age end before Mankind was industrialized and before Mankind in any way polluted the environment? Before any of the rain forests were cut down and before Man produced any Greenhouse Gasses.
That would also be way before the First Sport Utility Vehicle was built folks.
The Globe warmed up all by its little old self.
ICE AGE = Global Cooling - Ace Age Goes Away = Global Warming.
That has supposedly happened 5 other times in Earth history and before Man was here let alone a polluter.
One More -
Why are the Polar Ice Caps melting on The Planet Mars right now even though we have not even really been there yet?
Answer: Because Global Warming is caused by Cyclical Solar Activity AKA Good Old Mr. Sun.
And YES the Earth is warming up during an overall temporary warming trend as part of a larger cooling cycle and we are not going to stop it and we're not the cause of it.
