Daily Climate Report (5).

Today is Saturday 16th September 2023. The Keeling Curve records an atmospheric CO2 level for the 15th September of 418.16 ppm = 810.3 mg/m^3 = 3,263.454 GtCO2.

Given an equilibrium climate sensitivity (ECS) of 3°C, 418.16 ppm of CO2 yields global warming above the 1750 pre-industrial level (CO2 = 278 ppm) of 1.224729°C.

Wanting The Impossible.

The  Guardian newspaper of 2nd May contained the following item: https://www.theguardian.com/environment/2023/may/02/many-europeans-want-climate-action-but-less-so-if-it-changes-their-lifestyle-shows-poll. So: a majority of Europeans want climate action, but not if it has an adverse impact on their consumerist, materialist lifestyles! To be fair to them, the same can almost certainly be said of North Americans, many East Asians and Australasians, if not all of them. There are some climate scientists who seem to think that all we have to do to "solve" the climate emergency is end humanity's dependence on fossil fuels and achieve a complete transition of global energy production to renewable energy in as short a time span as possible. Would that things were that simple! They are NOT! In 2021, world energy consumption was 176,431 TWh (Terawatt-hours) = 635.156 EJ (exajoules). Oil, coal, natural gas and traditional biomass made up 529.6644 EJ of that, which is 83.39% of the t...
