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: Inflows don’t add to the level of carbon dioxide. Inflows set balance levels. Then actual levels approach balance levels according to a residence time of about 4 years. This leads, with some simple math, to the conclusion that the ratio of human-produced to nature-produced carbon dioxide in the atmosphere is equal to the ratio of their inflows, which is about 1:20. This conclusion is supported by common sense.
