We have one thread questioning popular wisdom about atmospheric oxygen depletion. Here's another about atmospheric carbon dioxide levels:
Some people contend that, in the long term, an increase in CO2 emissions isn't a real problem yet. If the CO2 partial pressure increases, more CO2 dissolves in the oceans. They provide effective negative feedback, stabilising the atmospheric balance. CO2 emissions would have to be several orders of magnitude greater before the oceans' ability to act as a buffer would fail. Anyone out there qualified to comment?
