Interesting article. Another character in the swarm of chemical bad-guys in the air. I am not as confident in how they can be so sure as to make such a long term prediction. Sure the CFCs could be main driving force behind climate change (according to the article), but isn't the global climate is much more complex and unpredictable than a single chemical? Ask the weatherman to predict which way the wind will blow and an honest one will tell you its a educated guess. And these guys are going much further than that in what they are claiming to be able to predict.
Permaculture is so potent it can address changes in climate either way, hot or cold, that's why we (or maybe just me?) don't care to worry about that stuff so much on the forums here.
