The 2nd worst year to year increase in CO2 concentrations over any March in 61 years was March 2021.

Here is the Mauna Loa CO2 observatory's data for the month of March 2012, Monthly Average Mauna Loa CO2

(Accessed April 10, 2021.)

March 2021: 417.64 ppm
March 2020: 414.74 ppm
Last updated: April 7, 2021

I keep a sortable spreadsheet of the monthly data found here: Trends in Atmospheric Carbon Dioxide

Monthly data is available going back 61 years. The increase measured over 2020 is 3.14 ppm. It is the second worst March ever recorded, after March of 2016, when the increase was 3.31 ppm over March of 2015.

If any of this troubles you, don't worry, be happy. We've spent nearly three trillion dollars on solar and wind since 2004. It didn't work to address climate change, isn't working to address climate change, and won't work to address climate change, but it's not practical results that count, but the good intentions, the dream and the fantasy that count.

As for nuclear energy, which was calculated in 2013 by James Hansen and a colleague to have prevented the release of around 31 billion tons of carbon dioxide, this while being vilified by people who know very little about science and engineering, don't worry, be happy. Head on over to the E&E forum where you can hear that it's "too expensive" and "too dangerous."

By the way, nobody knows what to do with dangerous fossil fuel waste. It's just dumped, indiscriminately, at a rate of roughly 95 million to 100 million tons per day. We couldn't care less. Not even counting climate change, dangerous fossil fuel waste kills between six and seven million people a year, around 18,000 to 19,000 people a day, more than Covid-19 ever killed on its worst day.

Here is the most recent full report from the Global Burden of Disease Report, a survey of all causes of death and disability from environmental and lifestyle risks: Global, regional, and national comparative risk assessment of 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks, 1990–2015: a systematic analysis for the Global Burden of Disease Study 2015 (Lancet 2016; 388: 1659–724) One can easily locate in this open sourced document compiled by an international consortium of medical and scientific professionals how many people die from causes related to air pollution, particulates, ozone, etc.

Climate change, according to what I hear, unlike nuclear energy, is decidedly not "too dangerous" nor, apparently, is it "too expensive."

Go figure.

In 2011, in coastal Japan, around 20,000 people were killed by seawater. We couldn't care less about them, but we hear all the time about nuclear reactors destroyed in the same event. How many people died from radiation again?

Go figure.

Have a pleasant Saturday evening.
