GCMs are wrong…right?

The water vapor mops up heat. As the vapor rises it leaves a cooler Earth behind. The water vapor rises and as it does the atmosphere becomes cooler and thinner and the water vapor eventually condenses. As it condenses the water vapor gives up its heat to the cold emptiness of space as the vapor returns to water and forms clouds or freezes and ultimately falls back to earth as rain, sleet, hail and snow.

Excerpts from Evidence for Negative Water Feedback

by Clive Best

Abstract: Positive linear climate feedback for combined water effects is shown to be incompatible with the Faint Sun Paradox. In particular, feedback values of ~2.0 W/m2K-1 favored by current GCM models lead to non physical results at solar radiation levels present one billion years ago. A simple model is described whereby Earth like planets with large liquid water surfaces can self-regulate temperature for small changes in incident solar radiation. The model assumes that reflective cloud cover increases while normalized greenhouse effects decrease as the sun brightens. Net water feedback of the model is strongly negative.  Direct evidence for negative water feedback is found in CRUTEM4 station data by comparing temperature anomalies for arid regions (deserts and polar regions) with those for humid regions (mainly saturated tropics). All 5600 weather stations were classified according to the Köppen-Geiger climatology…

About Wagathon

Hot World Syndrome—fear of a hotter, more intimidating world than it actually is prompting a desire for more protection than is warranted by any actual threat. A Chance Meeting– We toured south along the Bicentennial Bike Trail in the Summer of 1980, working up appetites covering ~70 miles per day and staying at hiker/biker campgrounds at night along the Oregon/California coast (they were 50¢ a day at that time). The day's ride over, and after setting up tents, hitting the showers, and making a run to a close-by store, it was time to relax. The third in our little bicycle tour group, Tom, was about 30 yards away conversing with another knot of riders and treating himself to an entire cheesecake for dinner. He probably figured Jim and I would joke about what a pig he was eating that whole pie and decided to eat among strangers. Three hours later after sharing stories and remarking on a few coincidences that turned up here and there, Tom and one of the former strangers realized they were cousins, meeting in this most unlikely place for the first time. ~Mac
