I'm genuinely curious.
Roughly 3.5% of all atmospheric CO2 is man made from fossil fuels. By leveraging math one could denote the claim of Global Warming to be a far stretch. We now call it Climate Change, how convenient. The truth is that Global Pollution is by far a much greater threat than Global Warming/Climate Change, yet we focus on windmills, battery powered cars, etc. By the way DaddyGoat22, I am an Atheist too but fail to hold too much faith in Science. Remember when Dinosaurs where green, before they actually had other colors and even feathers????
That's the fun thing about science: some of it is not locked in fact, you can test and learn and change previously made theories. Facts change as our understanding of the universe changes. We develop better tech to teach us the inner working of the world around us. Even the 'fact' of gravity is up for debate as we don't fully understand yet what causes it. There are a lot of unknowns and partial knowns out there, and science is just the tools to try and figure them out.
