Precipitable water is a measure of how high water would stack up if all the water vapor in the atmosphere would rain down, right now! It typically ranges between 22.4 and 24.2 millimeters. All the water vapor raining down would add up to about 0.9 inches.
Now a little bit of logic: the amount of water vapor in the atmosphere depends on how hot the oceans/lakes/rivers and whatever water is on/in the ground is. The hotter, the more evaporation. Simple. Therefore precipitable water should be a good proxy for surface water temperature. Let’s see what the history of precipitable water looks like. For that we go to NOAA’s ESRL.
We fill out the form, like this:
And this is what we get:
One would think that with constant warming, we should see the precipitable water always going up. But we don’t see that. We clearly see a CYCLE here, an invisible letter U or V. In fact, it reminds me of something we discovered here:
Let’s combine the two, while shifting temperatures forward 7 years:
Now that makes sense. You know what doesn’t make sense? The “consensus” temperature data. Here it is:
It is clear that Berkeley (and other similar outfits) do not perform proper latitude drift adjustment and so their result does not match what we should expect to happen to precipitable water level.
What we have here is a great confirmation that mainstream climate science has gone off the rails.
