Subject: Man-made contributions to global warming A key insight that my study has produced is: 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. Numerically, this means the 410-ppm present level of carbon dioxide is the sum of about 18 ppm caused by human inflows and 392 ppm caused by natural inflows. It also means that 18 ppm is the most that present human emissions increase the balance level of atmospheric CO2, and the most that the level of atmospheric CO2 can be reduced by eliminating all human CO2 emissions. This is independent of changes in natural emissions. Therefore, the concerns about heating by human CO2 are 4 percent of the total heating, whatever it may be, caused by the observed increase in atmospheric CO2. This is my hypothesis. My answer to the question of "what happened to all the human CO2" is that it has been absorbed by nature in the same proportion that natural CO2 is absorbed by nature. Human emissions behave exactly like a 4-percent increase in natural emissions. No one can measure natural emissions and absorptions within 4 percent. So, it is impossible to confirm or deny my hypothesis using data alone. My hypothesis rests on simple physics and logic. My hypothesis agrees with Salby and many others, and it disagrees with the IPCC. Ed Berry 1

Dr. Edwin X Berry is a physicist, a Certified Consulting Meteorologist (CCM) by the American Meteorological Society (AMS), and CEO of Climate Physics, LLC. His expertise is in atmospheric physics, climate physics, numerical models, and the philosophy of science. At Dartmouth, Berry studied probability and Markov chains and philosophy of science under John Kemeny, a student of Albert Einstein. At Nevada, Berry studied physics under Friedwart Winterberg, Heisenberg’s best student, and William T. Scott. Berry’s theoretical PhD thesis is recognized in textbooks as a breakthrough in the physics of rain and in numerical modeling, and still receives several citations per year. Berry is an American Meteorological Society (AMS) Certified Consulting Meteorologist (CCM). Berry is a pilot, with glider, power, and instrument ratings. Berry was chief scientist for Nevada’s Desert Research Institute (DRI) airborne research facility. He designed the first airborne, earth-referenced radar before modern GPS instruments. The Department of Defense (DOD) choose Berry to be the only civilian in a top-secret weather modification project. The National Science Foundation’s (NSF) chose Berry to be its Program Manager for Weather Modification, where he managed the Metropolitan Meteorological Experiment (METROMEX), the National Hail Research Experiment (NHRE), and university research. The Federal Aviation Administration (FAA) used Berry’s methods to reduce wind shear accidents at major airports. The California Energy Commission (CEC) funded Berry to perform its wind-energy study of the southern California desert. Berry developed a numerical model that was the first to present new evidence in a criminal trial. Berry’s model won the People’s Choice Award at Microsoft’s Windows World Open software contest against over 1300 entries. The University of Nevada Alumni Association awarded Berry with its Professional Achievement Award, following nominated by his mentor, Friedwart Winterberg. Berry has self-funded his climate research since 2001. His website,, provides climate education and information for the public.
