    Here is an interesting article based upon the title of this thread:

    http://www.bbc.co.uk/news/science-environment-11076786

    Enjoy.

    I agree with many aspects of this article as it explains that even by putting mirrors in space (ideally ~1/2 of the way between the Earth and the Sun), you do not solve the problems of increasing levels of in the atmosphere. Of course, less solar radiation () will reach the Earth and thus decrease the temperature globally. However, the solar radiation that does get there (which will still be high), will stay in the atmosphere for longer- if this was the only solution carried out. Not to mention that Earth also produces a considerable amount of infra-red radiation which shall not be affected by the 'space-mirrors' in any way.

    As for pumping lots of into the atmosphere, as the article mentions: we don't know what the exact effects of doing this are and could actually cause a problem the same magnitude as the one we have now, or even worse...

    It seems obvious and logical to me that the best solution is to prevent the additional being put into the atmosphere in the first place. Personally, I think the whole Anthropogenic Climate Change problem shall be solved in around 20-30 years when we finally achieve the full-potential of H-Fusion...

    And the sea level rise of 30cm to 70cm from the last IPCC is looking more and more like an underestimate.

    Having been raised on a Maine salt marsh, it's hard to imagine that I'll probably notice the rise in my life time, perhaps to a degree where my folks property won't be a viable place to live. We'd be the first generation in nearly 6000 years to see such noticeable change in a human life span.

    It's quite different for me, I live in the West Midlands in England, so sea level rise won't affect me at all. However, I am still only 16 and will most likely move somewhere else when I'm older- hopefully nowhere near to a high volume river or the sea.

    carbon won't be a problem fifty years from now. that is not an observation, it's a promise.

    algae used to synthesize bio-fuels will pull carbon dioxide from the atmosphere, and most likely use sunlight to generate sugars from it. function similarly to a plant in that it produces its own protiens by breaking down these high energy fuels, and biologically engineering the organism to produce usable biofuels will produce the net reaction of having solar powered cars.

    all the carbon produced in the cars will come from biofuel, and all the biofuel will come from carbon synthesizing organisms, adding and subtracting equal amounts of carbon dioxide. so, carbon is only a problem in the short term, and will become a long term problem only if bio-ethics goes in a regressive direction.

    You are wrong. First, this is too optimistic, second, it would not remove any carbon from the atmosphere. Burning biofuels returns all the carbon removed during production back to the atmosphere.
    And third, any such system is unlikely to be more effective than current solar power, as combustion engines are very ineffective.
