Here's something. I read that we have 3 times the trees here in NYS as we had in 1800. Goes without saying that we NEED more co2. How hard is that to understand.
Due to the amount of wood it took to power steam engines back then there was concern that the north east would be barren of timber. Once read that the average steam powered train used 8 cords of wood to travel 25 miles then it would have to stop and reload it’s wood and water supply. Throw in the fact that all heating was from wood and you have a huge demand.
