Cranky Uncle is the creation of scientist and cartoonist John Cook, who uses cartoons, humor, and critical thinking to expose the misleading techniques of science denial and build public resilience against misinformation. To explain why and how some people reject scientific evidence, Cook created the character Cranky Uncle, the family member we all have who thinks he knows better than the world’s scientists, in the book Cranky Uncle vs. Climate Change.
