Surface Global Cooling

Posted June 02, 2007 8:39 PM

From EcoWorld:

A Hypothetical Request for Proposal - Any Civil Engineering Firm: Build surface global cooling stations as described - these to effect surface temperature cooling through increasing low altitude humidity in an urban area. Example Project - Location: Urban Areas in the Sacramento Delta, California (1) The Design: Priority:  Build water sprayers that deliver moveable, high-volume, concentrated directional beams of [...]

That's about the silliest thing I've heard since Mexico proposed using big fans to blow the pollution out of Mexico City. Seems to me that they lack a sense of the scale involved. And what about the energy that would be consumed to attempt such a feat?

Here's my suggestion. Use a passive system to reflect the energy from the sun back into space before it converts to a longer wavelength and gets trapped by greenhouse gases. But still, the scale of such a project would be immense!

Has anybody on Earth ever demonstrated that carbon dioxide can trap heat energy? If so, then why don't we put carbon dioxide between the panes of double windows? It would be nice if we could use carbon dioxide to warm up our winters a little. Cooling the Earth with a water mist is a simple affair that actually uses free solar energy. If I step from my sunlit meadow into the adjacent forest, I feel a huge cooling effect partly caused by the evaporation of water from the leaves. In addition, the leaf surfaces scatter some but reflect back into space most of the long wavelength solar radiation. If incoming long waves from the sun are not attenuated very much, then outgoing long waves will also not be attenuated much.

Is there anybody on Earth who can tell me how to demonstrate the heat trapping effect of greenhouse gasses? I doubt it because they would have done it themselves a long time ago.

Different gases transmit or absorb energy at different wavelengths. These are well known characteristics. Shorter wavelengths pass through greenhouse gases, heat the surface of the earth and are re-radiated at longer wavelengths that do not pass through greenhouse gases. You can do the research. These are well established facts.

The absorbtion characteristics of carbon dioxide are only a small part of the thermal infrared spectrum. Whatever infrared is absorbed by a lump of charcoal, for example, will be reradiated just as thermal energy is reradiated by a molecule of carbon dioxide. The long waves are not reflected back to earth as shown by little arrows drawn by illustrators. The long wavelengths are reradiated in all directions including outer space. The research has been done. These are well established facts.

And then of course some of that re-radiation in the direction of outer space strikes another molecule and then some of that is re-radiated to earth and some to space which strikes another molecule and then some of that is re-radiated....

Any your point would be??

CO2 absorbs a fairly significant portion of the 20 degree Celsius black body radiation spectrum and I don't know the absorption bands for methane and other significant greenhouse gases but collectively do you say that it doesn't matter?

Or is that what Fox News says?

The point is that trapping earth heat with one-half of one percent of atmospheric carbon dioxide is like scooping water out of the ocean with a fishnet. Most of the water goes back into the ocean, and most of the heat goes into space. If it was that easy to warm the Earth with carbon dioxide, I would do it with my own resources out of consideration for the Eliza Doolittles of the world who yearn for a room somewhere far away from the cold night air. Nevertheless, all of my home lighting is compact flourescents, I get fifty miles per gallon with my ethanol-powered vehicles, and I have a prototype wind-powered home heating and cooling system that does not use any fossil fuels whatsoever. I also believe that, if the Earth ever gets inconveniently hot for whatever reason, we already have the technology to reduce the global temperature almost overnight. The carbon dioxide blamers say that, even if we eliminate carbon dioxide emissions completely, it will take fifty years to see any difference in the global warming trend. That philosophy, added to the billions of dollars in emission credit trading, appears to be a scam. Otherwise, why do those people object to methods such as mine that reduce carbon emissions?

I never watch or listen to Fox news. I don't need their analysis of anything I can study on my own. I can fully understand why scientists who depend on grant money to support their families will do and say whatever it takes to keep that money flowing. This is why no scientist anywhere will publicly demonstrate why carbon dioxide cannot possibly do any of the miraculous things claimed for it. Liberals say that any scientist who disputes the carbon dioxide controversy is only trying to refute the carbon dioxide contribution to global warming, and that is enough reason to ignore him. Circuitous logic? You bet it is.

Please read my submission carefully. You will see that I am doing everything Al Gore wants me to do. I believe that complaining about a problem is not really doing something about that problem. We do not need the government to tell us what to do. We already know what to do and how to do it, even if we don't believe in the reason why we are doing it.

Hire a "rain maker". These guys usually work for food.

Build huge, floating (gas filled) domes over all metropolitan areas and move all freeways underground. Trap all gasses and rout to scrubbers. Generate power using underwater turbines on the ocean floor in areas largely empty of fish populations. Convert prison populations into forced labor camps used to cultivate food. Swap the military budget with the space exploration budget. Pass a law stating all robot names begin with the initial R.
