Ever Expanding: In discussing the Sixth Assessment Report of the UN Intergovernmental Panel on Climate Change (IPCC, AR6, 2021 to 2023), researcher Andy May produces an interesting statistic – the ever-growing length of the reports. The first assessment report was 168 pages, the second 572 pages, AR5 was 1535 pages and AR6 2391 pages.
May also shows a graph of the “5-Year Running Mean of Tropical Temperature CMIP5 Anomalies of 300-200 hPa [units of pressure related to altitude] Layer (1979-2019) by Ross McKitrick and John Christy (2020). The difference between the temperature trends projected by the models and observed atmospheric temperature trends is increasing. So, the reports get longer as the physical evidence supporting them gets weaker. True bureaucracy in action.
This is why we will continue to warm. Simple enough.

Concentrations of CO2, CH4, and N2O now substantially exceed the highest concentrations recorded in ice cores during the past 800,000 years.
However the world was warmer than today only 4000 years ago as this find proves: https://climatescience.blogspot.com/2019/12/evidence-that-proves-alps-were-warmer.html
