From January 1st, 2020 through August 31st of the same year, fires in the Arctic Circle released 244 megatons of carbon, compared to 181 megatons for all of 2019.
Tsar Bomba's one and only test produced an approximate yield of 50 megatons or 50 million tons of TNT, making it the most powerful man-made explosive in history.
Another way of looking at it is that 20% of 100 million megatons is 20 million megatons, which amounts to 1 megaton hydrogen bomb at 6 kilometer intervals all around the planet.
Many of them have cheaper capture cost with the ability to improve the overall economics and kick-start a network that has the ability to scale up to 28 megatons.
In one of the clusters, we find the number of emitters with very low capture and storage cost in the range of 40 to 50 dollars per ton, but they only represent 1.2 megatons per year.
