🌊 The ocean was record hot in 2023, but surprisingly, the global carbon sink weakened.

A new study from our group unpacks why.

Check out the details in @jens-d-mueller.bsky.social ’s tweet 👇 and read the full study here: www.nature.com/articles/s41...

Asia’s haze affects ice and weather on the Frozen Continent Pollution emitted by fossil-fuel usage in Asia influences sea-ice coverage in Antarctica.

Tiny particles of pollution spewed into the atmosphere across Asia can affect climate as far away as Antarctica

Climate-driven shifts in Southern Ocean primary producers and biogeochemistry in CMIP6 models Abstract. As a net source of nutrients fuelling global primary production, changes in Southern Ocean productivity are expected to influence biological carbon storage across the global ocean. Following...

Climate change will increasingly impact the ocean around Antarctica, and the life within it, as it progresses.

Read the new paper by the excellent Ben Fisher and colleagues on how this will happen, what are the implications, and how we can improve our ability to predict the key changes.

Progression of ocean interior acidification over the industrial era The rapid downward progression of anthropogenic carbon accelerates ocean interior acidification and threatens marine biota.

Ocean Acidification is reshaping life and biogeochemical cycles.
In our latest study, Niki Gruber and I reconstructed its progression in the global ocean interior over the industrial era, based on our previous estimates of anthropogenic carbon accumulation.

Rain increases the global ocean carbon uptake by about 6% The ocean plays an important role in the global carbon cycle by absorbing about one-quarter of the carbon emitted by human activities every year

“The impact of rain on air-sea CO₂ fluxes hasn’t been systematically examined, but understanding it gives us a more complete picture…This is especially important since rainfall patterns over the ocean are expected to shift with climate change, and that could impact the ocean carbon sink.” 🌊🧪
