Ozone Layer Improving Faster Than Expected
SpaceAdmiral writes "Since the implementation of the Montreal Protocol, which limited ozone-destroying gasses like CFCs, the Earth's ozone layer has been recovering. However, new studies show that the ozone in the lower stratosphere is actually recovering faster than the Montreal Protocol alone can explain." From the article: "It's a complicated question. CFCs are not the only things that can influence the ozone layer; sunspots, volcanoes and weather also play a role. Ultraviolet rays from sunspots boost the ozone layer, while sulfurous gases emitted by some volcanoes can weaken it. Cold air in the stratosphere can either weaken or boost the ozone layer, depending on altitude and latitude. These processes and others are laid out in a review just published in the May 4th issue of Nature: 'The search for signs of recovery of the ozone layer' by Elizabeth Westhead and Signe Andersen."
Thanks, but I'll take scientific research over seemingly unfounded Slashdot postings any day.
The world isn't black and white, the fact that CFC's break down the ozone layer doesn't mean that other factor don't also play a part and the fact that other factors influence ozone doesn't mean that CFC's don't break down the ozone layer.
Of course this brain-dead theory has about as much basis in actual science as yours. If you don't believe the measurements indicating that the ozone hole was increasing (back when it was) why do you believe the measurements now that it is decreasing?
ok - so if I read this right it's saying that things aren't going as predicted. the implied message seems to be something like "science got it wrong" - but the whole point of science is to improve knowledge
Part of the problem with this system is that things like the Montreal Protocol are not science. It aims to solve a problem that might exist with remedies that might fix it. Note the usage of the world "explains" instead of "predicts". Most scientific theories are like economics: they can 'explain' plenty, but they can't really predict anything. Ultimately, all this talk about the weather is not science because we can't do experiments. There is simply no way to do scientific experiments with the global climate, and so theories about it don't quite make it all the way.
Using such theories to make worldwide policy is not exactly scientific when there is no actual evidence they have the verified power of prediction.
