One of the things I've learned is that people don't begin to take a topic seriously on hearing one person discuss it, or two. But when they've heard it six times, suddenly it seems important. So I encourage you to share in any group at all, just so more people are exposed and think about it. It would be great if a general consciousness of climate related issues rose at Atheist Nexus. As a secular and relatively educated community, we have an opportunity to be leaders among the general public in escaping cultural forms of climate denial such as not paying attention or not speaking in public on the topic.
