Atmospheric Carbon Dioxide

Although recent reports indicate that global carbon dioxide emissions are not increasing it is important to bear in mind that atmospheric carbon dioxide is increasing. The most recent daily average measurement of carbon dioxide at Mauna Loa is 406.29 parts per million. This measurement is much more precise than the statistics we are given for global emissions, which are based upon assumptions as much as upon measurements.

The International Energy Agency estimates that global energy related carbon dioxide emissions were flat for a third straight year in 2016 due to growing renewable power generation, switches from coal to natural gas, improvements in energy efficiency, and structural changes in the global economy. My guess is that overall carbon dioxide emissions are rising, notwithstanding the increase in renewable energy. After all the population of the most intensive creators of carbon dioxide, humanity, is growing very quickly and most humans are living longer than they did in previous generations.

It is ironic that in November 2012 when Mauna Loa reported atmospheric CO2 at 392.81 ppm there was far more interest and general reporting of climate change whereas five years later the issue is hardly reported, except en passant. When I first started writing on WordPress  in 2007 concentrations were around 380 ppm. 250 years ago the concentration was thought to be around 280 pmm.
