An important question is why there is such a focus by official agencies on the warmist year and whether that phenomonenon helps understand the causes of the increase in temperatures published by official agencies. As to the causes, the Australian BOM report acknowledges that “the Australian climate in 2016 was influenced by a combination of natural drivers and anthropogenic climate change”. But the UK Met mentions neither of these and the Aus BOM does not say anything about the relative contributions made by natural drivers and human activity. We can say however that, even if temperatures have increased by about 0.8C since around 1900 (which is the standard official message), this has done no harm. To the contrary, as illustrated in the attached report by the FAO, 2016 produced record agricultural output and since 1900 there has been a strong increase in food and other consumer production, with poverty rates falling. This suggests that, even if CO2 emissions did contribute to increased temperatures, there is no need to reduce the CO2 concentrations which remain in the atmosphere as a result human activity to date. Indeed, given that the increase in published temperature of 0.8C since about 1900 has done no harm, it also suggests there is no substantive basis for the government to justify taking action to reduce emissions from hereon unless it can be established that major increases in temperatures will now occur and damage production capacity.
