This article gets it spot on. When we realize fully how small the atmosphere is compared to the amount of carbon dioxide and other waste gases we are pouring in to it now, it is hard not to take climate change seriously. It would be like pumping car exhaust into your living room and hoping that by some lucky coincidence it won't affect us and saying we don't know enough to do anything about it- it would be foolish not to take it seriously and look for a long term solution that involves both technology and governance. Finding solutions that maintain much that is good about the modern world is not easy, but denial is not helpful.
