Daily Climate Report (19).

Today is Saturday 30th September, the last day of this month. CO2 Earth reports an atmospheric CO2 level of 418.3 ppm for the 29th, up from 415.79 ppm for the 29th September 2022, an increase of 2.51 ppm, or 0.604% p.a.

The Keeling Curve has a reading for the 27th of 417.56 ppm. The NOAA Global Monitoring Laboratory, on the other hand, gives readings for the 28th of 418.2 ppm, 29th of 418.3 ppm, and 30th of 418.22 ppm. 418.22 ppm = 810.4 mg/m^3 = 3,263.923 GtCO2.

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...
