...that we have it in for this particular technology," he says. "It's just that we don't see Sasol prospering in a world of carbon caps." One way to cut emissions is to capture the carbon dioxide. Davies says Sasol currently captures about 50% of the CO2 emitted during the conversion process and is experimenting with algae that absorb the gas, possibly allowing the company to raise that figure and introduce refinements of Fischer-Tropsch that will help it emit less. But for now, 50% of the CO2 will be released into the atmosphere, and there is still...
...mind-bendingly complex international negotiations, we need to have a plan in place by the start of 2010 to ensure that there isn't a fatal gap between the expiration of Kyoto and whatever comes next. (If a year or two should pass without a clear international cap on CO2 emissions, both government and industry might lose the incentive to invest in greener technology.) All of which puts a lot of pressure on little Copenhagen...
...kept our planet warm for billions of years - and is now, thanks to human activity, making us too warm. When we think of carbon, the first word we associate with it is emissions, a concept that evokes a tinge of illegality, as if emitting a mere molecule of CO2 were a crime. But as Eric Roston points out in his engaging new book, The Carbon Age: How Life's Core Element Has Become Civilization's Greatest Threat, C is about more than just CO2. "If you think about carbon only in terms of climate change, you're missing...
...coral are left weakened and defenseless against disease. Increased carbon dioxide concentrations in the atmosphere also lead to more acidic seas, which impairs the ability of corals to form their skeletal reefs. (In acidic water, the reefs simply dissolve.) "Corals appear to be particularly sensitive to the buildup of CO2," says Kent Carpenter, the lead author of the Science study and the director of GMSA. "The corals will be the canary in the coal mine in terms of the effect climate change will have on our oceans...
...could make the entire ocean into a marine park and still lose the coral, if we can't stop climate change. As temperatures rise in the ocean, bleaching events will become more and more common. According to a study published in Science late last year, if CO2 levels continue rising unabated, by 2100 coral could be utterly extinct. "If we can't contain the CO2 problem and enact strong coral reef conservation measures, we will lose them," says Carpenter. The depressing fate of the coral could be a reminder that climate change has the power to undo all the work...
