Are Simulated Ocean Deoxygenation Rates Consistent with the Observational Reconstructions?

Takamitsu Ito, Yohei Takano, Yassir A. Eddebbar, Jerry Tjiputra, Zhankun Wang, Shoshiro Minobe, Lijing Cheng, Juan Du, Yumi Abe

It is currently debated whether Earth system models (ESMs) can reproduce observation-based long-term changes in global and regional deoxygenation rates. Both models and observations include uncertainties, which must be considered…

Northern high latitudes could become a net carbon source below 2 °C global warming

Rebecca M. Varney, Daniel Hooke, Norman Steinert, T. Luke Smallman, Camilla Mathison, Eleanor J. Burke

Under historical warming, terrestrial ecosystems within the northern high latitudes have been a net carbon sink, providing vital mitigation against anthropogenic emissions of CO2. However, the long-term stability of this net sink…

Projected future warming induces a long-term loss in global dissolved organic carbon pool

Jerry F. Tjiputra, Xosé A. Álvarez-Salgado, Richard Sanders, Damien Couespel

Abstract Dissolved organic carbon is the largest reservoir of reduced carbon in the ocean but its sensitivity to climate change and consequent impacts on ocean biogeochemistry remain poorly understood. Here,…
