      However it is propably smarter to store just the carbon in the form of coal. That would only be 0.475 trillion t. Thats like 1200 times the global paper production in mass.

      So I tried doing my calculations with better data.

      My estimate is that there are 2041 gigatonnes of co2 in the atmosphere remaining post industrial revolution. This equivalent to about 5% of the mass of Mauna Loa, in the form of wood equivalent carbon. Still a bewilderingly large amount, but much smaller.

      We would need to sequester approximately 1,133,900,000,000 megagrams of wood from trees to offset these emissions.

      Would also love a sanity check. I’m using this dataset and some conversion factors for my math: https://ourworldindata.org/grapher/cumulative-co-emissions?country=~OWID_WRL
