IPCC Report

My Commentary on Friday 12 October examined the IPCC report and, inter alia, drew attention to the fact that “there have been two periods since the early 20th century when temperatures have been relatively stable despite CO2 concentration levels having increased strongly. This suggests little or no correlation between the two ie prima facie, this means that even though human activity does contribute to CO2 concentrations, they could be having only a minor effect on total temperatures”. I also pointed out that, as only a relatively small proportion of CO2 concentrations appear to stay in the atmosphere, this suggests that other factors are likely to be more causitative contributors to temperature increases. By contrast, the IPCC analysis implies that temperature increases are all due to increases in CO2 concentrations and that this conclusion is science-based.
