Wieder so ein cooles Türchen im #Adventskalender !

Falls sich jemand ein Bild davon machen möchte, wie die Land-Ozeanverteilung auf der Erde vor 359mio Jahren, am Ende des Devon aussah, und wie CO2 und Temperatur sich damals entwickelten: Filmchen gucken?

Das D in der Buchtabenleiste des Charts steht für Devon. Die Fischgräte steht für ein Massenaussterben .

Attached: 1 video A new paper by #Judd and #Tierney et al maps temperature and CO2 for the last 485 million years. https://www.science.org/doi/10.1126/science.adk3705 Not the first attempt, other teams came before, and others will come after. This one raises the global temperature bar to 35°C, and averages around 28 or so. Their CO2 is almost always about 1000ppm and notably doesn't really follow the temperature evolution. #GavinSchmidt blogged about the new paper: https://www.realclimate.org/index.php/archives/2024/09/phantastic-job/ I needed to see their charts in context with the Earth's land-ocean-mountain configuration so I put it all together in a movie, with one of Chris Scotese's tectonics animations. https://www.youtube.com/watch?v=bzvOMee9D1o&t=22s The two globes are western and eastern hemisphere. Also, because it was global #ClimateStrike today, the music I added is what #IgorLevit played a day after the big #climate protest in 2019, to honour the millions of people on the streets. "We the people will never be defeated". #paleoclimate #PlateTectonic #CO2 #Klimastreik #FridaysForFuture

It raises the global temperature bar to 35°C, and averages around 28 or so.
Their CO2 is almost always about 1000ppm and notably doesn't really follow the temperature evolution in its ups and downs.

The chart from the movie in the toot above on its own.
The paper's main chart doesn't contain CO2, but in the supplement is one. So I copied that to the main chart.

But I feel it is important to digest it together with the information how Earth actually looked when global temperature spiked or dropped. So the movie above is going to be my go-to reference now.

This video from (around?) 1970 about the newly formed theory of plate tectonics is surprisingly good, with didactic tools that are just great. (You see the age in the video quality though.) 50min
