The movie started out with James Hansen claiming that Venus was 600 degrees because of 97% CO2 which was trapping heat.
Apparently Hansen can’t do his own basic math.
Hansen says that each doubling of CO2 causes a 3C temperature increase. Venus has 97% (0.97 mole fraction) CO2. In order to get to 97% on Earth, we would require less than 13 doublings. That would raise temperatures by about 35 degrees, using Hansen’s own exaggerated theory. Nowhere near 600 degrees.

Hansen’s own theory can’t explain the high temperatures on Venus, yet he continues to parrot the same mindless nonsense decade after decade.
