Talk about the Climate Crisis
Reach out to someone you know – family member, friend, co-worker, etc. - who is not concerned (or at least hasn’t expressed concern) about the climate crisis.
Have a conversation -- do this mostly by listening, not pretending you agree with them. People are more likely to engage in a real conversation if you listen to them. Find common ground. Everyone likes to breathe clean air. Maybe the issue to come together on is ending fossil fuel subsidies. That can work when speaking with a Libertarian, for example.
