I don't think climate change denialists are the target audience for this, though.

I think this chart is extremely useful as a way to show people which approaches are more effective at mitigating temperature increase. For example, in my experience in this types of discussions, some people like to claim that "population control" should be a top priority. However, this page shows that the effect of it would actually be rather small compared to other approaches like carbon pricing or reducing methane emissions.
