But this isn’t a very basic and well understood issue we are discussing. There is consensus, and it would be an interesting personality type to happily swim against the tide of scientific opinion at this stage, but climate change is not at all basic and not at all well understood. Why? Because we can’t go into a Lab and reproduce experiments ( too many variables) and instead have to rely on models that in a decade will no doubt be considered crude.
The wiggle room for conjecture and argument is what makes this something we debate. If it was straight forward science ( like scattering of electromagnetic radiation by gas molecules) there would be no debate in mainstream society.
