Cranky Uncle is a Fake Expert

Developed by Skeptical Science, a website devoted to true ‘Climate Science’, and against real scientific discussion, the app brands as ‘misinformation’ anything that questions the status quo IPCC view, and it brands as a ‘fake expert’ any retired physics professor from Princeton. But Climate Science relies upon the basics of physics: Arrhenius, Stefan and Boltzmann, Tyndall, Planck … they were ALL physicists.
It’s this app that’s the Fake Expert!

Good idea, but underdone

Good concept, but really incoherent. It is like it was not tested in house. Working through the app, it’s unclear if you are meant to answer a question yourself, or from the uncles perspective.

Hilarious and Effective

An unusual but effective and funny way to learn how to navigate conversations with climate deniers. The app could be more polished, but it’s fun and fully functional. Also, a lot of the reviews from quite a while ago say you need to enter an email before you can do anything. You don’t anymore.
