...cutting global greenhouse-gas emissions in half by 2050. It was the clearest signal yet of the international community's willingness to grapple with the long-term danger of global warming, which threatens to change the face of the planet if nations don't shift to a low-carbon economy. Politicians at the summit were pleased. "The science is clear, the economic case for action is stronger than ever," said Jose Manuel Barroso, president of the European Commission. "This is a strong signal to the citizens of the world...
...gets started, we may in the end be helpless to stop it. But fear has never been a very good motivator, especially not for the decades-long societal changes we'll need to make to slow climate change. Instead of the apocalypse, what we need is positivity. A low-carbon world will bring benefits that go well beyond simple survival, and that's a message that needs to be heard. But if it really is that bad and the end of the world is nigh - well, at least we'll have Kutner's book to help us meet the annihilation...
...matter is murky. In May, the U.N. Convention on Biological Diversity called for a moratorium on everything but "small" experiments "in coastal waters." Climos chief science officer Margaret Leinen concedes that even if the idea works, it won't remotely deal with all the planet's excess carbon. But she says it doesn't have to. "We're not thinking of this as solving the problem," she says. "We're looking at this as one of a whole portfolio of techniques...
...water, where it is taken up in the shells of marine creatures, which fall to the seafloor and become limestone. Essentially, says Kurt House, a Harvard graduate student who came up with the idea when he was jogging by the Charles River, the ocean "could become a giant carbon dioxide collector...
...much smaller, mass-produced scrubbers, each fitting into a 40-ft.-long (12 m) shipping container. Scatter 20 million of them in remote spots around the world, and you could take care of the emissions from all the vehicles on the planet. And what do you do with the carbon you collect? For starters, you could sell captured greenhouse gasses to, well, greenhouses; farmers pay up to $300 per ton for the stuff to help plants grow. If the scrubbers were deployed on a grand scale, though, lakes of liquid CO2 would need to be pumped into deep underground reservoirs...
