Honestly i don't know how anyone can say whether or not Global Warming exists or not. I mean... to do so you would need to know how much CO2 is produced by the world.
We have no clue how much CO2 and other greenhouse gases are produced normally because we have no ways to measure some of the biggest natural causes of such gasses.
The basic assumption that global warming is man made is that the planet naturally gets rid of all the CO2 that is natural, but can't get rid of man made CO2. Which doesn't explain how tempertures have changed before then... and why Nature CO2 is different then CO2... when it has the exact same atomic composition.
