  • A re-assessment of the global carbon budget shows the natural land sink is substantially smaller than previously estimated, indicating emerging impacts of climate change on the evolution of the carbon sinks.

  • The ocean carbon sink strengthened in previous warm El Niño years due to reduced CO2 outgassing in the tropics. Here the authors show that the ocean carbon sink declined in 2023 despite record-high sea surface temperatures (SSTs), primarily due to SST-driven outgassing of CO2 in the subtropics.

  • A hybrid approach reconciles discrepancies between observation-based and ocean model estimates of the ocean CO2 sink. It shows that ocean models underestimate variability, while observation-based methods tend to overestimate the 2010s trend.

  • Ocean uptake of CO2 slows the rate of anthropogenic climate change but comes at the cost of ocean acidification. Observations now show that the seasonal cycle of CO2 in the ocean also changes, leading to earlier occurrence of detrimental conditions for ocean biota.

  • Biodiversity in established or proposed Antarctic Marine Protected Areas is threatened by climate change. The authors show that projected ocean acidification is severe in Antarctic coastal waters due to strong vertical mixing of anthropogenic carbon.

  • Carbon uptake by the ocean has increased alongside rising atmospheric CO2 concentrations, but with substantial variability. This Review examines trends in ocean CO2 uptake and the internal and external factors driving its variability, finding an ocean uptake of –2.7 ± 0.3 Pg C year–1 for the period 1990 through 2019.

  • Weddell Sea dense water formation facilitates carbon sequestration on centennial time scales. The authors show that for a high-emission scenario, carbon sequestration is reduced by 2100 due to water-mass property changes on the continental shelf.

  • The Southern Ocean carbon sink is projected to move poleward under a high emission scenario with increases in the Revelle Factor and carbon uptake that are biologically-driven in summertime and solubility-driven in wintertime linked to sea-ice melt, suggest CMIP6 Earth system model simulations.
