You are confused. The models using educated guesses are coming from the climate alarmist side. This is a physics calculation. Physicists know how much IR is being transmitted to the earth. They know how much CO2 is in the atmosphere. They know how much IR can be absorbed by CO2. Plus it isn't all IR, it is a specific spectrum of IR that CO2 can absorb. Is there some uncertainty in the measurements and the following calculations? Of course. But the uncertainty is way less than the model climate scientists use. The models used to predict significant temperature increase add uncertainty on top of uncertainty. And that error is never analyzed, admitted to, explained, or attempts made to reduce it. Because they are stupid politicians. They are also all lawyers who have no ability to understand any of this, no disrespect to Deez or Joe Fan or others. But the guys in the government are all that plus if they get more power because of the climate narrative, what do they care? They want more power. It will take people holding their feet to the fire and holding their hands along the way. If you don't, it will only be 5-10 years until we get blackouts in Texas too. This summer the unreliable sources had Texas power the most expensive in the world. We somehow didn't get charged for it because electricity pricing is controlled by the government and is a morass. But if we had to pay the true cost we would have all turned our ACs off for a couple of months so that we could make our mortgage payments. We really are playing with fire here. Cowtow to these green dictators much longer and we will all suffer greatly.
