And this is also the first time Global Warming has ever happened too
it's the first time it's ever happened without a corresponding natural phenomena. There haven't been any orbital changes, changes in solar output, or any other natural events that have caused past warming. The only correlating factor is rising atmospheric CO2.
There's a simple way to dismiss global warming as a result of man-made activities:
1. Prove the planet isn't warming (all the data says it is)
1. Prove that CO2 isn't a greenhouse gas (we've known for 100 years that it is)
2. Prove that atmospheric CO2 isn't rising (it is)
3. Prove that rising CO2 isn't the result of human activity (we know that it is from isotope analysis)
Minty is right, we have more scientific evidence of warming from human activities than we do for many other well-adopted theories.
