Very few times I read newspapers these days. After hiking down a mountain last evening I stopped in the valley, and grabbed a paper in a cafe there. The main Norwegian business paper DN (Norways equivalent to FT). Many years ago the paper used to be a little about derivatives etc. Now front page was about our leading climate scientists. Very good!
One top scientist there were from same top university as Paul. She had Phd physics from oxford. The article was about what these climate researchers did themselves to save us all, and what they recommended others to do. This researcher had decided not to get children to help save us from reaching the tipping point of climate change. She in particular was against getting children early in life as this was particular bad for climate (Climate gas output generation overlapp). All in the paper (Dagnes Næringsliv Sat 12, 2019)!!! This was when the brilliant idea hit me, she was right! If we just all skipped getting children for only 3 to 4 generations then the tipping point will be avoided.
but then likely only the people that want to do something about the climate will follow her advice. This means their genetics will die out and only climate deniers will get children (deniers?) and then we are doomed! Complex systems that only can be solved by Tax?
