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.: Continued human emissions will not increase the 18-ppm human-caused balance level. They will only maintain it. Therefore, there is no cause for alarm. The human-caused 18-ppm would disappear in a few years if human emissions stopped. Nature’s 392-ppm balance level would remain. The Paris Climate Agreement proposed to reduce worldwide human emissions by 28 percent of 18 ppm, or by 5 ppm. The Paris Agreement would not change climate and would not stop natural climate change.
