Why not destroy such sceptics (on HN or anywhere else) regarding the rate of climate change and related topics?

Must surely be easier than presenting a classic logical fallacy - argument by authority and thinking that nails it.

Maybe the link is indeed total rubbish but talking about man-hours and 'trained PhD's' is irrelevant. Feynman explains nicely: https://youtu.be/EYPapE-3FRw.
