To be clear on what this means: this is exactly like if a climate deniers had taken someone’s paper using 4xCO2 experiment in a bunch of models and said “these people don’t even know if the climate would warm by 20 or 60C, they don’t understand anything about the climate!”.
Looks like folks think it's ok to lie in an op-ed on @theguardian.com because cumulatively the authors have "100 years of climate science experience". I think science should not be misinterpreted to make a political point (even 1 I agree with), and what you see in the screenshot is totally false.
