The scientists are, as usual, cautiously optimistic about the results. They warn that this is not proof the Earth can heal its atmosphere while we continue to dump pollutants into it. Yes, it's true that more hazardous gases are being naturally removed in the Atlantic than previously thought, but they are uncertain how this slice of evidence fits into the larger picture. It may be the case that previous estimates in the other parts of the world were too high or that sources of ozone and methane exist for which we are not aware. Either way, it is a great impetus for reducing these gases in the first place—we know the planet can do quite a bit of housekeeping on its own, so why not help it out with a head start?
