But the source of the warming should be completely open for debate. I for one am looking at the sun as the source, starting with the sunspot maximum event of 1958 that sparked the US government to create Nasa.
Why is that a productive debate? Even if CO2 is not the source, we should still eliminate our reliance on the combustion of fossil fuels because those fuel sources still undeniably pollute our environment in other serious ways. The mining and burning of coal is bad for our environment even if CO2 was a non-issue.
For me, it's about the truth and I'm pretty tired of being dismissed because I dont agree with the anti-human narrative that's becoming the mainstream.
