There are a few scientists who assert that the total amount of the feedback is low. But there is a strong and growing concensus on climate sensitivity. The "many people" who allegedly disagree are actually a tiny minority, way out on an increasingly shaky limb.
So let me ask you: why do you personally believe climate sensitivity is low? Is it because you choose to believe 5 scientists rather than 5000, because it makes you feel good to do so? Is it political? Or is it because you actually know something about climate sensitivity and see some flaw in the research of the 5000?
