Five Reasons Why Water Vapor Feedback Might Not Be Positive
Spencer finally distills his main arguments into a list of five points…
1) Evaporation versus Precipitation
2) Negative Water vapor Feedback Can Occur Even with a Water Vapor Increase
3) Cause Versus Effect
4) Evidence from Radiosondes
5) The Missing “Hot Spot”
And the list is not impressive. Point two might be the strongest? and even that is suspect.
I am not saying that’s what I necessarily believe. I will admit to having waffled on this issue over the years, but that’s because there is evidence on both sides of the debate.
At a minimum, I believe the water vapor feedback issue is more complicated than most mainstream researchers think it is.
