In a highly recommended lecture, Dr. Murry Salby, professor and Climate Chair at Macquarie University, Australia, debunks the popular myth that man-made CO2 controls global temperature. Dr. Murry proves from observations the opposite is true: natural changes in global temperature instead control CO2 levels and that man-made emissions do not control either atmospheric CO2 or the climate. Dr. Salby also debunks the notion that changes in greenhouse gases control ocean temperatures, showing that the huge heat capacity of the ocean means that a tiny ocean cooling of < 0.0005C could cause all atmospheric warming of < 1C observed since pre-industrial times. Dr. Salby shows why nature, not man, is the cause of the increase in CO2 by demonstrating that only the integral of temperature changes explains the changes in atmospheric CO2, not a slow steady rise in man-made emissions.
