Neil DeGrasse Tyson has opened up science to a whole new generation, and has expanded interest in communities which previously hadn't shown much. For that, we're eternally grateful. But there are limits to intelligence, and he, like many others, crosses that limit when he wades into climate science.
Having studied Economics, I compare climate science, as a science, to Economics. The level of predictability, due to the number of unknowns and variables, is very low. You can model all you want, and you can know how different parts of the economy impact to a very large degree, but still be far off. The same is true with climate. The various elements involved in developing climate models are fairly well known, but it's the stuff they don't know that's causing problems. I have yet to see a model that is remotely close to predicting anything. This doesn't make climate science less scientific. Science is about explaining, not predicting. Predicting is a nice benefit in constrained systems.
But Tyson's tweet is lauded as "destroying" a key claim of "deniers" (we aren't deniers, we are SKEPTICS, which is what most good scientists are whenever there is a lack of evidence or an inability to replicate results). Problem is, it destroys nothing. No skeptic ever complains about scientists agreeing. That, in itself, isn't even an issue. The question is why are they agreeing? In fact, Tyson's tweet opens more questions than it answers. If a standard scientific conference is indicative of the amount of disagreement that takes place, then clearly the wide level of agreement on this particular issue is an anomaly and you should wonder why this is taking place? Well, of course, the answer is politics. But Tyson, in crafting his guilt bomb, realizes if he doesn't support the massive Appeal to Authority which is the entire Manmade Climate Change argument, then he loses the game. So he pours it on hot and heavy, because he is the authority!
