climate-change event, the Paleocene-Eocene Thermal Maximum, some 55 million years ago, the Earth heated up about 6C over 20 000 years and then took 200 000 years to return to near pre-perturbed conditions. The planet underwent significant changes during this period; ocean acidification accompanied mass extinctions on land and in the sea. The sedimentary rocks that formed before and after this event are so different that they were divided into separate geological epochs long before scientists discovered what had caused the split. For a great many species, adaptation was simply not possible, even over many thousands of generations. Business-as-usual scenarios using current emission trajectories suggest that a similar degree of climate change is likely, but over less than 1/100th the amount of time. Ivy Mike, you still don't get it do you. I am advocating for anyone on this site who is aware of what is ahead to forgo their biological imperative because it hardly matters if we are going extinct. I am asking them to not selfishly put a burden on a child for the desires of the parent. I remember once hearing a program where they asked people what they would do if they knew an asteroid was going to hit the planet and destroy the world in 10 years and there was nothing they could do about it. One woman said she would have a child because she wanted to experience childbirth. She had absolutely no thought in her mind about anyone but herself. Perhaps if the
