IPCC is a huge report and it is a result of a work of international cooperation of more than a hundred of countries. As such it's not an easy read. Here are some book suggestions, some of them could be easier to read: https://www.nytimes.com/interactive/2020/climate/climate-change-books.html https://www.nytimes.com/interactive/2020/climate/climate-cha... But the typical people denying the thing even existing will seldom be willing to hear from anybody but those they trust -- it's a kind of tribal thing. You can try to give the facts to somebody, but for that you should first learn yourself enough answers to the issues they will typically raise. Basically you should really expect all the arguments like in the links and learn enough to understand the topic and be able to give a reliable answer: https://grist.org/series/skeptics/ https://grist.org/series/skeptics/ or https://opr.ca.gov/facts/common-denier-arguments.html https://opr.ca.gov/facts/common-denier-arguments.html But people don't tend to believe just the "facts" if these are just told to them, even the opposite happens, they have to be involved in the process of learning -- the whole process of coming to new perspectives they can relate -- and that takes a lot of time and patience.
