I've tried. But anything other than doom-and-gloom "we are so totally screwed unless we dismantle X" bounces right off of their heads. Like, I've tried pointing out it's an energy production issue not an ecological one so we should probably, in the short term, focus on grid scale carbon-free production sources. Yeah, doesn't work. Well, it kinda does until I point out the only thing we got that could do that right now is nuclear without substantially changing our standard of living. Off the table.
They are wedded to the idea that we must live in solar-powered mudhuts as subsistence farmers to fix this. Well, anyone that isn't part of the urban elite of course. I've pretty much come to the conclusion that the advocates don't want a solution that works they want a solution that fits their view of the future.
