What we have here is a religious cult called “Scientism”.
I’m calling shullbit on carbon dioxide-induced global warming. Doesn’t exist. Mechanism by which even high concentrations of carbon dioxide “trap” heat just is not there. Carbon dioxide does not “trap” any more heat than the nitrogen or oxygen components of the atmosphere.
The big mover is water vapor, or rather, the heat of vaporization of liquid water to water vapor, or the heat of fusion, the freezing of ice out of water. Carbon dioxide does none of this under normal earth atmospheric conditions. To visualize this, it takes some 80 calories of heat energy to convert one gram of ice to one gram of water, even though the temperature of both the ice and the liquid water is 0 degrees Centigrade. To convert one gram of water at 100 degrees Centigrade to one gram of water vapor at 100 degrees Centigrade takes some 540 calories of additional heat energy. Now, water does NOT have to be heated to 100 degrees Centigrade to have the phase change from liquid to water vapor, as it occurs at all temperatures within the range of liquid water, it just gets faster as it gets hotter. Even ice can form water vapor, in a process called sublimation, as both the heat of fusion and the heat of vaporization are combined to effect the phase change.
All this heat energy has to go somewhere, and that is why there are clouds in the stratosphere, very high above the earth’s surface. Water vapor is much lighter than the other components of the atmosphere, and it rises quickly into the heights, where at night, it gives up its heat, becomes very small ice crystals, and the heat is radiated off the earth during the night hours. Ice crystals, being much more compact than water vapor, have a tendency to sink lower into the atmosphere, at which point the warming rays of the morning sun melt the ice crystals into droplets of water, which at a certain point condense into large enough drops to fall to earth as rain. It is a huge and continuously operating heat transfer machine that has functioned perfectly since the earth cooled enough for the formation of liquid water from water vapor.
Scott Adams (Dilbert) had a profound point a few weeks ago:’I might be persuaded about Global Warming danger if someone could show me that there was any evidence of damage from the warming we’ve had so far.’ Not 50 or 100 years from now. Where’s the destruction now, the lost lives?
I wonder what the consensus of scientists would be if there were no research grants.
