It sounds like both the weather and climate change and we have a very poor understanding of both, so it’s better not to incur trillions in known costs for a climate mitigation goal of dubious probability.
Since trillions have already been spent, can they reveal the present percentage of co2 in the atmosphere NOW and what it was in 1900, 1950, 2000 2010 and how were these numbers arrived at....i.e., calculated or actual (which is impossible).
