Scientists Blocking out the Sun

Ashtangiman writes to tell us The New York Times is running an article about geoengineering in which many solutions to global warming include decreasing the amount of sunlight that the planet sees. The ideas are not new, many have been around for quite some time, however they have been relegated to the fringes of science and many have never been published because of this. From the article: "Geoengineering is no magic bullet, Dr. Cicerone said. But done correctly, he added, it will act like an insurance policy if the world one day faces a crisis of overheating, with repercussions like melting icecaps, droughts, famines, rising sea levels and coastal flooding."

    that plants now receive far less light. Less light, means slower growth, less uptake of CO2, etc.

    Off hand, all the solutions (CO2 sequestering,etc) that allow us to keep our oil/coal dependancies will probably come back to bite us. Far better to bite the bullet now, and switch to nukes(fission and fusion) and alternatives.

    Some people just don't get it. Perhaps the earth is supposed to get warmer.


    Perhaps it is. Perhaps human civilization isn't supposed to continue. Ultimately I for one don't care much about supposed to. There are rather serious consequences for us if the earth does continue its current—and unprecedented in the history of human civilization—rapid and accelerating warming.

    I don't mind at all that people are researching potential ways to prevent those disastrous consequences before they materialize. Some of them might have unintended consequences, but that's more, rather than less, reason to investigate them as far in advance of the need to implement as is possible.

    Why is it the same people who love evolution are the same people who want to keep everything the same?


    Its not about "loving" evolution. People who acknowledge the demonstrated reality of evolution are, however, unsurprisingly also likely to recognize that drastic changes in environment can be very bad for life forms that are very successful in the old environment.

    OTOH, people that believe in invisible fairies devoted to protecting them from all material harm as long as they clap hard enough—a kind of immature religious faith that is sadly common in the US—are prone to ignore the facts and just ask everyone else to just clap harder.
