Atmospheric oxygen links reveal higher Southern Ocean productivity
What the study found The study found that Southern Ocean net primary production is about 6.5 ± 1.36 PgC yr−1, which is higher than most CMIP6 model and satellite-based estimates but consistent with Argo oxygen-based estimates. Why the authors say this matters The authors say these productivity estimates provide quantitative benchmarks and, together with airborne…
Global coral heat stress reached record levels from 2018 to 2025
The 4th global coral bleaching event shows 87% of reefs in continuous heat stress since 2018, marking a shift to near-annual bleaching that overwhelms coral recovery capacity.
