Most people are influenced by others whom they see as having something in common with themselves.  It could be anything, such as a favorite sports team, shared religious beliefs or love for their kids or grandkids. 

 

When it comes to getting climate-change doubters and deniers to share your climate concerns, facts alone probably won't help much.  Showing them what you both have in common and sharing what the impacts of climate change mean to you, your family or whomever or whatever else matters to you is much more likely to be persuasive.
