Ed Berry, PhD in Physics with a focus on atmospheric physics. Dr. Berry’s theoretical PhD thesis is recognized as a breakthrough in the science of rain formation and in the use of computer-based numerical models. His model of the microphysics of rain formation is summarized in cloud physics textbooks and taught in university courses. After debating climate alarmists for many years, I have concluded the only way to win a climate debate (note I did not say “convert the believer”) is to clearly negate the alarmist hypothesis. Otherwise, a climate debate can go on for years and accomplish nothing.
