Evidence warmth produces more CO2, rather than vice versa

Following the Mt Pinatubo eruption in 1991, change in CO2 dropped dramatically. Conversely, following the natural warming of the 1998 El Nino, change in CO2 increased dramatically. Sources: Climate4you.com & The Climate Scam SE

In his recent lecture, Professor Murray Salby notes that changes in CO2 levels due to natural variation are so large that man-made CO2 becomes irrelevant. As we await publication of his paper, the graph above from climate4you.com may offer a taste of how Dr. Salby arrived at his conclusions. Dr. Salby notes that when temperatures dropped following the volcanic eruption of Mt. Pinatubo in 1991, a dramatic decrease in the rate of change in CO2 followed in 1992-1993. Subsequently, the increase in temperatures due to the El Nino of 1998 was followed by a dramatic increase in the rate of change in CO2. These natural variations are independent of and overwhelm human emissions of CO2, and show that warmth produces more CO2, rather than vice-versa.

As stated by Professor Judith Curry,

"If Salby’s analysis holds up, this could revolutionize AGW science."

Salby notes his results are new and did not exist when the IPCC's latest report was prepared. The IPCC assessments and climate models are based on the erroneous assumption that the climate is controlled by human emissions of CO2. According to Salby, this is not the case and the ability to predict and control what future carbon dioxide levels will be, and to anticipate and influence future climate, is poor.
