Coral Reefs Need Deep CO2 Cutbacks Soon

Wednesday, September 24, 2008 — How much carbon dioxide is too much? According to the UN Framework Convention on Climate Change, greenhouse gases in the atmosphere need to be stabilized at levels low enough to “prevent dangerous anthropogenic interference with the climate system.”

but scientists have come to realize that an even more acute danger than climate change is lurking in the world's oceans—one that is likely to be triggered by co2 levels that are modest by climate standards. ocean acidification could devastate coral reefs and other marine ecosystems even if atmospheric co2 stabilizes at 450 ppm, a level well below that of many climate change forecasts, report long cao and ken caldeira.
