	Ozone hole has unforeseen effect on ocean carbon sink http://apocadocs.com/s.pl?1246022773 The Southern Ocean has lost its appetite for carbon dioxide, and now it appears that the ozone hole could be to blame. In theory, oceans should absorb more CO2 as levels of the gas in the atmosphere rise. Measurements show that this is happening in most ocean regions, but strangely not in the Southern Ocean, where carbon absorption has flattened off. Climate models fail to reproduce this puzzling pattern. The Southern Ocean is a major carbon sink, guzzling around 15 per cent of CO2 emissions. However, between 1987 and 2004, carbon uptake in the region was reduced by nearly 2.5 billion tonnes -- equivalent to the amount of carbon that all the world's oceans absorb in one year.

Good grief -- this is good for ocean acidification, bad for global warming... or is it the other way around?
