President Joe Biden and his climate envoy John Kerry just hosted the Leaders Summit on Climate to work on limiting carbon dioxide. One has to admire their ability to go from failure to failure with no loss of enthusiasm. Over the last 30 years, there have been many carbon dioxide-limit summits with no success.

Our latest inadvertent experiment in carbon dioxide reduction, the COVID-19 lockdown, while dropping the world’s carbon dioxide output by 17%, made no difference. Carbon dioxide continued its relentless climb in our atmosphere.
