People never ask the right 3 questions:
1) does global warming exist? Answer: yes, and global cooling. Has been cyclic for billions of years.
2) Is it man made? Answer: no. Lots of BS on this aspect, for example the greenhouse gas nonsense. 98% of greenhouse gases are water vapor. Do the math. CO2 is been blamed for warming, when it fact CO2 levels rise approx. 400 years AFTER the temperature rise. See the Coca Cola effect. Add heat, gas comes out of solution, not the other way around.
3) Is global warming bad? No, but global cooling causes everything to DIE. In the 1500s grapes were grown in England, agriculture was booming.

As with just about everything else, to find the answer, just follow the money.
