The recent IPCC email leaks seem to confirm my opinion (I think it is mostly a red herring), but I agree with above posts that citing anecdotal evidence (ie - well it’s freezing/burning up this year) on either side is silly.
I see climate change as a dangerous power grab by socialists, while the sustainability movement is something that is rapidly gaining traction in the free market. Sometimes we can get impatient as designers, but when we think of how far things have come in a mere several years, there is ample room for optimism.
