A 1,200-year-old data series offers no room for conspiracy theorists and science deniers. For all those who claim that the climate has changed much more dramatically in recent centuries than it does today: For 1,200 years, the date of the first cherry blossom has been meticulously recorded in Japan. One can see a millennium of natural fluctuation and then the significant earliness in recent years. The cause of the change has been known for 150 years, the topic has been on the agenda of the global scientific community for 50 years, and there has been an international agreement on it for nine years. And CO2 emissions around the world are reaching new record levels every year. And since at least one day ago, it has been clear that the #Kleiko may have money to spare, but ideas to spare – and not just when it comes to man-made climate change. ourworldindata.org/data-insi… via Michael Kipp
