What I mean with "Time will show who's right in the end" is that you can denny reality, but you can't escape it. Physical laws, do not simply change just because we don't like them or based on what we think to be true. Someone jumping out of a window from a skyscraper might not believe in gravity up to the moment he dies, but gravity doesn't care it's simply there. So if the climate sceptics are right? Wonderfull! I certainly hope they are right. But as said, nature doesn't give a flying fuck about what anyone of us hopes to be the truth.
