Sure there are controversies on Twitter. But I'd say the loonie & conspiracy theorist segment is larger on Hive proportionally speaking. Crypto was originally and still is to a large degree anti-establishment and so are the so-called "free thinkers". A lot of them believe in the same set of conspiracies at the same time.
CO2 emissions from human activities mostly since the beginning of the industrial revolution have driven global warming as well as the acidification of the oceans. Warmer air is able to contain more water vapor. CO2 remains gaseous in temperatures found on Earth except for the most extreme cold conditions below about -78.5 C when it exists in the solid state under atmospheric pressure.
I'm not going to debate this with some random dude on the internet. The scientific consensus on this is very strong.
Where were the humans when CO2 was much higer than now?

And please mind your language. Unlike Twitter you can get flagged for insulting others.
And btw, science is NOT about consensus, in contrary.
The climate of the Earth, including the CO2 concentration of the atmosphere, has undergone a large variety of changes of great magnitudes due to differing natural causes over different time scales in its very long past.
However, human existence let alone thriving in humanity's current numbers is predicated on a pretty narrow set of conditions. It is not the Earth and life on it themselves we should be worrying about particularly over geological timescales. It is the rapidity of change brought about by the impact of our civilization - on ourselves - that should concern us.
