Permian–Triassic mass extinction pulses driven by major marine carbon cycle perturbations
Abstract The Permian/Triassic boundary approximately 251.9 million years ago marked the
most severe environmental crisis identified in the geological record, which dictated the …

Rapid rise in atmospheric CO2 marked the end of the Late Palaeozoic Ice Age
Atmospheric CO2 is thought to play a fundamental role in Earth's climate regulation. Yet, for
much of Earth's geological past, atmospheric CO2 has been poorly constrained, hindering …
