Who's the skeptic? Because there is literally no way in existence to test the hypothesis that "greenhouse gases" raise the global temperature. Not to mention that there is no control group and these "scientists" think they can measure atmospheric particle densities from millions of years ago but can't accurately predict the weather 10 days from now. The greenhouse effect is because it's literally a glass box sitting out in the sun and "greenhouse gases" are pumped into them because they make shit grow like crazy.
So you have some "science" that would get an F on a 3rd grade science project. Seriously, who are the real skeptics?
