Cross plot of δ18O carbonate vs δ13C carbonate of Baltica and Laurentia records. Although Baltica has lower Δ47-Temperatures than Laurentia, both have similar ranges in δ18O carbonate.Credit: Proceedings of the National Academy of Sciences (2024)

What are the units in the graph?
“Then all collapsed, and the great shroud of the sea rolled on as it rolled five thousand years ago.”
― Herman Melville, Moby-Dick or, The Whale
And all this time I thought it was 539 million years. Who know?
And it turns out that it’s going to reach Earth-killing levels in 2031 ... unless we give up all electricity generation worldwide.
Join the Zero Electron Movement and raise taxes to 99.9%.
In go plants, life and sunlight. Out comes oxygen.
Totally AWESOME, DUDE!
That article brings back memories of geochemistry classes 40 years ago.
Very interesting. Have you noticed a political bias in their conclusions? If so, what are you conclusions?
No units. They’re ratios, so the units of measurement cancel out when the ratios are calculated.
“New evidence supports theory that oxygen isotope ratio in seawater slowly increased over last 540 million years”
I had nothing to do with that. Honest.
Of course they’re ratios. Log of the ratio. Zero on x axis is one. No increase or decrease.
But ratios of what to what?
Look up “oxygen isotope ratios” in Wikipedia. It will explain better than I can.
Thanks.
Actually I just noticed the delta.
I’m partly to blame for the methane rise.
So, are we all going to die, or what?
