The 5,000-Kilometer Echo of Earthβs Worst Extinction
How matching chemical signals in two distant ancient oceans show the end-Permian crisis was a single, connected planetary event. A team of scientists collects samples...
252 million years ago, Earth faced its worst extinction.
Now scientists have found the same chemical signals in rocks from Iran and South China, nearly 5,000 km apart.
The message is clear: the end-Permian crisis wasnβt local chaos. It was one connected planetary event.

Really interesting mechanism here I think: thousand-year orbital cycle modulation can drive million-year pulses in nutrients, oxygen and (we hypothesize) biodiversity during early animal evolution

A: no we didn't analyse phosphorus isotope ratios in rocks
B: NOBODY analyses these
C: because phosphorus only has ONE stable isotope

Figure from the paper showing our model results when considering the tropical vegetaiton collapse - a long-high temperature period following the PTME
Great to see this finally out today! We show that the collapse of tropical vegetation during the Permo-Triassic extinction is a key driver of the long-term super-greenhouse climate that followed it.

It still may be LIP weathering, perhaps with more uplift and different hydrology, and maybe the Neoproterozoic system is less resilient to temperature change... plenty to investigate!

Yes, same! And even if we assume more weathering then we start to get in trouble with the strontium isotope record!

Did flood basalt weathering draw down significant amounts of CO2 in the Mesozoic? We think not so much:
