We'll need to do some serious geo engineering on purpose to reverse all the geo engineering we've been doing by accident. Current efforts are all about stopping the problem from getting worse. We reducing the pace at which co2 emissions grow. But they are still growing, not shrinking. But the point is that, unless we do some geo engineering, those levels are not coming down by themselves any time soon.
