Uninteresting facts

I moved the following text to here for discussion before reinsertion because of the following reason: The years and names when people has written interesting facts is not what is interesting per se. Rather write what they found, not that they found out something. Mikael Häggström (talk) 06:40, 19 April 2008 (UTC)

A preliminary study by Edward Teller and others in 2002 presented the pros and cons of various relatively "low-tech" proposals to mitigate global warming through scattering/reflecting sunlight away from the Earth via insertion of various materials in the upper stratosphere, low earth orbit, and L1 locations.

If the link weren't dead, I would disagree. It's quite useful to mention that somebody did a thorough review of various proposals, if the article provides a working link where readers can go to learn more. If I can find the original article online I will add this back to the WP article.--Srleffler (talk) 05:10, 21 April 2008 (UTC)

Mirrors at Tropical Sea

Hasn't anyone suggested to cover the oceans near the equator with floating mirrors, reflecting the sunlight back into space, reducing heating? The efficiency is perhaps only 5-10% of a mirror in space (because of earth's rotation, clouds, dust and dirt in air and on mirror), but they could be cheaper. The albedo of water is considered very low. Rising it to 100% with a mirror should make a big difference. A mirror could be kept clean by rain or have it floating only inches above the water surface to become regulary washed. It could be submerged below the surface during cyclones to prevent damage. At night the mirror should be replaced by the opposite of a mirror, a surface with high emittance that radiates more heat into space, cooling down further. Mirrors are to be placed in sea areas poor of nutrient contents to not disturb plankton production. Searching... Najro (talk) 14:53, 24 July 2008 (UTC)
