To understand how to reverse global warming, it is necessary to know how much excess carbon dioxide is added to the atmosphere every year. According to two recent articles, there seems to have been an increase of 3 ppm (parts per million) of carbon dioxide levels in the atmosphere over the year 2018 – 2019. In an article from Slate (published in 2014), 2 ppm of carbon dioxide weighs 40 billion tons. Therefore, in the year 2018-2019, the amount of carbon dioxide in the atmosphere would appear to have grown by 60 billion tons.

It should be self-evident that, if one accepts the concept of climate change (and the science behind it), in order to reverse climate change, human beings must curb the growth in yearly CO2 emissions. If more CO2 is added to the environment every year than what is removed (through carbon capture), how can climate change be reversed? For this particular thought exercise, I am going to assume that the world somehow manages to hold yearly CO2 emissions to a steady rate of 60 billion tons.

With this amount of CO2 established, tomorrow (actually, this evening), I hope to lay the groundwork for what removing 60 billion tons (and 1 pound) of CO2 from the atmosphere every year could actually look like.
