Atmospheric Residency & Oomph (part 4)
A quick look at the HADCRUT5 global mean annual temperature anomaly and human emissions over the last 170 years
A warming Earth will produce more CO2 from natural sources, so we should observe a steadily rising atmospheric concentration arising from ocean outgassing, fungal decomposition of organic matter (a process that yields 85Gt of carbon per year compared to humanities 10Gt) and other processes such as rock weathering. In part 3 of this series we discovered that a rising CO2 trend for natural sources can only be observed if the atmospheric residency of human carbon dioxide emissions is under 30 years, and not the +200 years favoured by alarmists. I whipped out my big spanner of temporal causal modelling and we discovered that the best match to the time series data was obtained for human emissions residencies of 4 – 5 years, this result being in keeping with the low end of estimates suggested by the IPCC. Once again we find things not adding up on the climate ‘science’ front!
Before I bring this little taster series on atmospheric residency to an end I want to reveal just one more slide upon which we may all cogitate. I simply couldn’t resist using human emissions residencies of 5 and 200 years to generate predictions for global warming and then compare these to the HADCRUT5 reference series as well as each other. Grab a slice of toast and have a feast on this:
