@primonatura Compare this level with that in the Mid-Piacenzian Warm Period of the Pliocene Epoch, & NB the #climate #conditions at that time. The ONLY reason we don't have the same conditions is because of the level of cooling aerosols in our #atmosphere. See: https://www.nature.com/articles/s41598-020-67154-8.pdf; https://arxiv.org/pdf/2212.04474, p.27 (the whole paper should be read).
