Based on a few individual experiences, concern about climate change vs (perceived/actual) lack of concern in EA seems like a division that might be a sticking point for potential EAs.
Possible cruxes:
- EA's current material isn't convincing to people who see Global warming as a top priority.
- This is a sticking point for (some) people who might otherwise join EA.
- There are many such people.
It's not super clear to me either way but I'm curious what people think.
Just wanted to point out that the 80,000 hours problem profile on Climate Change (published on May this year) might fit what you're describing. I still think there are significant improvements to be made (discussed on my comment on the answers section).
