It's surprising the article doesn't mention CFCs: > The simulations showed that the rate of Arctic warming in a world without CFCs would be cut in half – a striking effect for a category of substances that are only present in small quantities to begin with. To ensure the result was not simply a quirk of the simulation, the researchers ran the experiment using two different climate models and arrived at a similar outcome. https://www.theglobeandmail.com/canada/article-cfcs-are-a-major-driver-of-arctic-warming-study-finds/ https://www.theglobeandmail.com/canada/article-cfcs-are-a-ma... The danger here is that there's something else we fundamentally don't understand about the atmosphere.
