  • Oceanic Anoxic Event 2 was triggered by Kerguelen Large Igneous Province volcanism. Short-lived sedimentary mercury enrichments and changes in sediment provenance suggest that southern hemisphere volcanic activity drove climate and carbon cycle changes.

  • The Paleocene–Eocene boundary coincided with runaway global warming possibly analogous to future climate change, but the sources of greenhouse gasses have remained unresolved. Here, the authors reveal volcanism triggered initial warming, and subsequent carbon was released after crossing a tipping point.

  • The causes of Mid-Pleistocene Transition global cooling 1 million years ago are still unknown. Here, the authors find the subarctic North Pacific became stratified during these glaciations due to closure of the Bering Strait, which would have removed CO2 from the atmosphere and caused global cooling.

  • Modelling studies propose sea ice to be one of the underlying mechanisms for the Mid-Pleistocene transition. Here, the authors show Mid-Pleistocene subarctic North Pacific sea ice dynamics based on biomarkers and biogenic opal accumulation rates, supporting the importance of sea ice for climate change.
