Human CO2 has little effect on the carbon cycle https://edberry.com/blog/climate/climate-physics/human-co2-has-little-effect-on-thecarbon-cycle/? Hello Dr Ed Berry, Thank you for your latest paper. I have been pondering this subject for ~12 years and am still doing so. I wonder if the following close relationship of dCO2/dt vs Temperature from my 2008 paper is helpful to your hypothesis. Please consider and advise. In my January 2008 paper, the close correlation of the velocity dCO2/dt and delta Temperature proves that atmospheric CO2 changes lag atmospheric temperature by ~9 months in the modern data record, and this observation suggests Climate Sensitivity to Atmospheric CO2 must be very small, and may not even exist in measureable reality. This plot approximates the dCO2/dt vs T correlation. Major volcanoes El Chichon (1982) and Pinatubo (1991+) disrupt the relationship. http://www.woodfortrees.org/plot/esrlco2/from:1979/mean:12/derivative/plot/uah6/from:1979/scale:0.22/offset:0.14 Best personal regards, Allan MacRae Carbon Dioxide Is Not The Primary Cause Of Global Warming, The Future Can Not Cause The Past By Allan M.R. MacRae, January 2008 http://icecap.us/images/uploads/CO2vsTMacRae.pdf Excel: http://icecap.us/images/uploads/CO2vsTMacRaeFig5b.xls [excerpt] The IPCC’s position that increased CO2 is the primary cause of global warming is not supported by the temperature data. In fact, strong evidence exists that disproves the IPCC’s scientific position. This UPDATED paper and Excel spreadsheet show that variations in atmospheric CO2 concentration lag (occur after) variations in Earth’s Surface Temperature by ~9 months. The IPCC states that increasing atmospheric CO2 is the primary cause of global warming – in effect, the IPCC states that the future is causing the past. The IPCC’s core scientific conclusion is illogical and false. 1
