Yes to a point, Just seemed a little snarky. Scuba tanks have to have a little co2 in them with the oxygen to trigger respiration for instance. But the levels in our atmosphere are in no way at a dangerous level and co2 is NOT a greenhouse gas that causes warming. Now there are gases like nitrogen and nitroxide that in fact do. We have our government and others actively geoengineering OUR destruction which they do admit. All of the "climatologist experts" that the government keep marching out's own data shows the real facts of it all but truth loses their cushy funding. You can trust when I say that I actively study and research and experiment and am way ahead of the curve on curing my "Ignorance".
I simplify my language sometimes so I don't come off as an arrogant asshole but it is what it is. Have a glorious day my friend. Find Your balance.

CO2 is a greenhouse gas, though. Even if it wasn't, it would be a weak argument because its increasing abundance in the atmosphere would still be a major problem, as it also causes ocean acidification.

I'm not by any means refuting that academia is in dire need of systemic changes. That doesn't change the fact that CO2 being GHG is one of the least disputable claims in this whole dilemma. What makes you think it's not? Can you back that up with something?
