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
#GavinSchmidt blogged about the new paper: https://www.realclimate.org/index.php/archives/2024/09/phantastic-job/
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.

Not the first attempt, other teams came before, and others will come after.

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".

Gibt auch ein neues Paper über 485mio Jahre absoluter Temperaturentwicklung, das Gavin Schmidt hier bespricht

Und ein neues, "Evidence suggesting that earth had a ring in the Ordovician" , https://www.sciencedirect.com/science/article/pii/S0012821X24004230
von AG #Tomkins et al,
das einen Riesenmeteor vor 466mio Jahren im Einzugsbereich der Erde auseinanderbrechen sieht, was einen Ring wie den Saturnring um den Äquator der Erde gelegt haben könnte, der – und jetzt kommts – durch die Abschattung zu einer Abkühlung geführt haben würde,
bis die Brocken auf die Erde geplumpst waren.
Dafür haben sie die Landmassenverteilung von vor 466mio Jahren angeguckt und gesucht, ob heutige Äquivalente, die damals nahe dem Äquator lagen, viele Impact Krater haben. Irgendwie so.
Aber das neue Temperaturpaper hat vor 466mio Jahren kein Tal. Erst 16mio Jahre später kommt ein langes Temperaturtal.
Naja. Vll haben die einzelnen plumpsenden Brocken jedes mal einen Dinosaurierwinter verursacht wie vor 55Ma.
Très spannend.
RealClimate: A truly impressive paper was published this week with a new reconstruction of global temperatures over the last ~500 million years. There is something tremendously satisfying about seeing a project start, and then many years later see the results actually emerge and done better than you could have imagined. Especially one as challenging as accurately

KEULEN (ANP/AFP) - Schotland kan tijdens het EK voetbal geen beroep meer doen op Kieran Tierney. De 27-jarige verdediger van Arsenal keert terug naar zijn club om zich te laten behandelen aan een hamstringblessure.
