Strategy tip: Don't tell him to know his place and listen to the enlightened; send him the next set of links that will satisfy and maybe further stimulate his curiosity. Without those links, your last paragraph is really a statement about your own approach to the problem, with a little condescension thrown in for his failure to follow the same pattern. It's counterproductive to your own goal of persuasion. In any scientific endeavor (not just climate change), when a skeptic takes the time to engage, the response should be data, not appeal to authority. Put differently, environmental scientists have a credibility gap in some segments of the populace, and it isn't possible to fix any credibility gap through peer pressure. You can only offer evidence, tailored where possible to the listener's level of interest and sophistication.
