How to reduce global warming? Block out the sun.

Instead of reducing emissions, maybe we can block out the sun. This is a proposal offered by the United States in response to a draft of a UN report on climate change, prepared by the Intergovernmental Panel on Climate Change. According to the linked article, the U.S. has resisted a treaty that would involve binding targets for emissions reductions, and is instead pushing for the exploration of techniques for blocking out the sun, including (according to the Sydney Morning Herald article) "putting a giant screen into orbit, thousands of tiny, shiny balloons, or microscopic sulfate droplets pumped into the high atmosphere to mimic the cooling effects of a volcanic eruption." This is via Yale Law professor Jack Balkin, who speculates that there is Biblical precedent for this proposal.

Close the loop.

Maybe there's something to this plankton-as-panacea idea? "Gummy bear"-like sea creatures absorb great amounts of carbon before dying and sinking to the bottom of the sea. Previously on mefi: Sustainable oil and Oil from plankton.

First concrete global warming proof emerges from ocean

The strongest evidence yet that global warming has been triggered by human activity has emerged from a major study of rising temperatures in the world’s oceans. The present trend of warmer sea temperatures, which have risen by an average of half a degree Celsius (0.9F) over the past 40 years, can be explained only if greenhouse gas emissions are responsible, new research has revealed. The results are so compelling that they should end controversy about the causes of climate change, one of the scientists who led the study said yesterday. "The debate about whether there is a global warming signal now is over, at least for rational people," said Tim Barnett, of the Scripps Institution of Oceanography in La Jolla, California. "The models got it right. If a politician stands up and says the uncertainty is too great to believe these models, that is no longer tenable."
Studies confirm global warming underway

Pretty Polluted

Visualizing power plant impact. A nice use of flash to show the impact of electricity generation around the USA. You can zoom in on individual states and then individual power plants. Or you can view the national impact of several regulatory regimes.
