Carbon Dioxide and Methane trap heat. If you study the history of science, you’ll see that no hypothesis can never be 100% verified. Carl Popper showed, however, that an hypothesis can be falsified. Given the preponderance of the evidence from basic chemistry, as well as long-term trends (our planting zones have shifted northward), I will continue to consider the gigatons of Carbon Dioxide we emit to be a grave threat to civilization. That should not be a political issue.
Thus I do label the GOP approach to climate change as well as, in many of its quarters, a 6000-year-old earth as “anti science.” I miss the old GOP from the pre-Reagan era, but there you have it.
