It'd have no effect at all. We know this because that's exactly what ClimateGate was. A huge pile of hacked emails leaked, and they included climate scientists saying things like: - The world had stopped warming and they couldn't explain that - They were mixing and matching data to ensure graphs showed temperature's going up - They were working to prevent papers that disagreed with them from being published - They were deleting emails and other material to avoid having to release them etc Guess what - they denied everything, the emails were roundly denounced by a friendly media, and nothing happened to any of the people involved. Really, you don't need deepfakes to create climatology skepticism. Climatologists are very good at creating it all by themselves.
