Global temperature is now hotter than any time in the Holocene - the entire history of human civilization. #ClimateStrikeOnline #FightEveryCrisis #NetzstreikFürsKlima
A version of this graph including future scenarios was properly peer-reviewed and published in Nature Climate Change here: https://www.nature.com/articles/nclimate3013 And covered e.g. by the Washington Post: https://www.washingtonpost.com/news/energy-environment/wp/2016/06/23/this-chart-perfectly-explains-whats-at-stake-in-the-quest-to-stop-climate-change/
I'm always amazed how little known these results from paleoclimate research are in the general public. As this is getting a lot of interest, here some further information. We discussed these results at Realclimate after they first came out: http://www.realclimate.org/index.php/archives/2013/09/paleoclimate-the-end-of-the-holocene/
Also, we can now reproduce the ice age cycles of the entire past 3 million years in our global climate model, including ocean, atmosphere, land and marine biosphere, carbon cycle and ice sheets, driven merely by their ultimate cause, the orbital cycles: http://www.realclimate.org/index.php/archives/2019/04/first-successful-model-simulation-of-the-past-3-million-years-of-climate-change/
A new study by Kaufman et al. was published last week featuring a comprehensive global database of Holocene
paleotemperature records: https://www.nature.com/articles/s41597-020-0445-3 Results are highly consistent with the graph that starts this thread.
