IPCC's "Darkest Yet" Climate Report Warns of Food, Water Shortages 703

The Australian reports that "UN scientists are set to deliver their darkest report yet on the impacts of climate change, pointing to a future stalked by floods, drought, conflict and economic damage if carbon emissions go untamed. A draft of their report, seen by the news organisation AFP, is part of a massive overview by the Intergovernmental Panel on Climate Change, likely to shape policies and climate talks for years to come. Scientists and government representatives will meet in Yokohama, Japan, from tomorrow to hammer out a 29-page summary. It will be unveiled with the full report on March 31. 'We have a lot clearer picture of impacts and their consequences ... including the implications for security,' said Chris Field of the US’s Carnegie Institution, who headed the probe.

The work comes six months after the first volume in the long-awaited Fifth Assessment Report declared scientists were more certain than ever that humans caused global warming. It predicted global temperatures would rise 0.3C-4.8C this century, adding to roughly 0.7C since the Industrial Revolution. Seas will creep up by 26cm-82cm by 2100. The draft warns costs will spiral with each additional degree, although it is hard to forecast by how much."

    That's precisely the problem. The warming isn't going to cause much of a problem for most people old enough to post here. By the time the problems get too bad to ignore, we're already committed to even more problems, because the excess carbon dioxide stays in the atmosphere for hundreds of years. That's why we keep getting these warnings, so we can avoid those problems before it's too late.

    You are aware, I trust, of these things called plants. It turns out that they absorb carbon dioxide right out of the air. What's even cooler is that the more CO2 that's in the air, the faster they grow and thus the faster they absorb it. This is why greenhouses will often run with drastically increased CO2 levels.

    Wow! This changes everything, you should tell someone about your amazing discovery!

    Send it into Nature

    Abstract:
    I don't think global warming will happen because the plants will eat all the CO2 out of the air

    Introduction:
    Because plants use C02, so if we make more CO2 we'll get more plants and we'll have less CO2!

    Conclusion:
    No CO2 means no global warming!

    Future Work:
    We've got lots of CO2 so figure out why still there's more CO2 instead of more plants.
