Permian–Triassic mass extinction pulses driven by major marine carbon cycle perturbations
The end-Permian mass extinction was linked with ocean acidification due to carbon degassing associated with Siberian Trap emplacement, according to boron isotopes from fossil shells and reconstruction of the carbon cycle.

Exciting new paper using boron isotopes in brachiopods across the Permo-Triassic (biggest mass extinction event ever!).. nature.com/articles/s4156… Great work by Hana Jurikova, formerly of @GFZ_Potsdam, and others.
Remember that time when 95% of marine life died because of massive CO2 release? Ocean acidification supercharged weathering, which triggered global eutrophication and hypoxia. First thing I've read in a while that makes 2020 seem fine. #LearnFromThePast
