And it's a huge distraction. Afaik (and I'm no climate researcher), the increased albedo of greater cloud coverage due to greater vaporization because of higher temperatures is the only known negative feedback effect. Everything else, be it reduced albedo due to less ice cover, increased release of Methane due to melting permafrost, increased release of CO2 due to more forest fires, etc. only accelerates global warming. So "more CO2 = more warmer" might be hilariously simplified, but it ain't wrong.

Only those who try to maximize profits while skirting the risk of a revolt care whether global average temperature will be 1.2 or 1.8K above pre-industrial average in ten years. For the rest it's already too warm, the damage is already plainly visible.

We don't need better models to predict future warming; we dragged our feet long enough that we can now look at historic data to see where it's going.
