Sentences with phrase «water vapor feedback cancels»

And, the evidence now suggests that a NEGATIVE water vapor feedback cancels about 75 % of the previously assumed impact of CO2 (abstract found here).

While CO2 itself will likely cause warming, the Gray effect induces negative water vapor feedback canceling most of the warming.

Not exact matches

Moreover, for temperatures similar to the present global mean, water vapor feedback actually cancels out some of the positive curvature from the fourth - power law (see Chapter 4 of my book, Principles of Planetary Climate).

They most certainly don't cancel one another as the water vapor feedback is much larger and the cloud feedback either adds or is small to allow for measured values of 2 C per doubling.

«Thus the possible positive and negative feedbacks associated with increased water vapor and cloud formation can cancel one another out and complicate matters.

There is some uncertainty in the water vapor and cloud feedback strength, but this is not a serious uncertainty since water vapor and clouds are constrained by the Clausius - Clapeyron relation, and since the SW and LW radiative effects of clouds cancel each other to a large degree.
