The answer to speech you don't like is more speech, not censorship. And I'm with the poster who talked about "bullshitting" because climate change has a lot of the smells of that very thing.
Ironically, in doing so, you've highlighted a great example to show why we use the scientific method and how well it works - thereby weakening your own position that the science is not settled. And to that end, I think you should take 15 minutes and read this essay by Isaav Asimov:

So when you say that climate change isn't settled science, my response is that you may be a little right: there are those who may overstate the science in order to push their own agenda. But you are, without a doubt, very wrong.
Also, for everyone who suggests that belief in the reality of climate change is politically motivated - what is the actual motivation? Sure plenty stand to profit from the sustainable energy industry, but if it was all a hoax in the first place, why would so many be pushing to go the hard way? Why not just throw in with traditional energy industries? Obviously the answer is that only one side in this "debate" is primarily politically motivated, and it's the side that stands to lose a lot of easy money, not the side that stands to make some lesser amount of hard money.
So, if you're betting on another Galileo moment, you're wrong. You're wrong now, and even in the unlikely case of a Copernican climate science revolution, you will remain wrong. Nature has this nasty habit of being consistent.
