> And yes carbon likely plays a role as we can model an atmosphere and see this. But it’s probably not as significant as the hundreds of other natural variables. And yet, thousands of scientists who spend their entire careers on figuring this out are pretty damn sure what's driving current warming: it's greenhouse gases, primarily CO2. They use this thing called the scientific method, which includes a whole bunch of actually measuring, modeling, predicting, and checking each other's work. Forgive me if that isn't a whole lot more convincing than some offhand conversation with an unknown person on a tech news site.
