Even if he was the greatest physicist , that wouldn ' t make him the greatest climate scientist I don ' t think you understand how the climate science has worked so far . A bunch of young left wing activist scientists with a cause claimed that a 120 part per million increase in CO 2 in the atmosphere can cause catastrophic climate change . Teller looked at the physics and said no , it can ' t . If you have a degree in physics , then you are wrong . Or better yet , answer me this . Show me the physics , the equations , the numbers , that show definitively how if we increase the amount of CO 2 in the atmosphere from approx . 280 ppm to approx . 400 ppm , it causes more than a trace and barely measurable of global warming . Then we have the inconvenient truth that most of the 120 ppm increase is actually from natural causes . Man ' s contribution is closer to around 16 ppm . Then explain how after the amounts reach near 400 ppm and above , the warming effect diminishes because it is logarithmic . The ability to absorb heat becomes saturated . Less and less warming as the amounts increase . Okay , Mr . M y P h y s i c s D e g r e e isbetterthanEdwardTellers ' s , have at her .
