In biology/geology "#marinesnow" refers to the #organicdebris of organisms from higher #waterlevels. The #carboncycle thus transfers #CO2 to the #seabed, thus binding the #greenhousegas.
B. Borer et al. (2026) found that #microbial components of this "snow" induce #calciumcarbonate #dissolution in higher waters, reducing their #settlingvelocity and requiring consideration in future #climatemodels.

🌍 Can we predict atmospheric CO₂ growth?

Using 6 Earth System prediction systems with an interactive carbon cycle, we show:
• Useful predictions of atmospheric CO₂ growth and air-land CO₂ fluxes for up to 2 years
• Air–sea CO₂ fluxes are predictable for a longer time, up to 5 years
• Predictability partly linked to ENSO — but not exclusively

An important step toward early warnings for carbon cycle shifts and climate extremes.

How microbes use ancient carbon?
For a study published in the journal Communications Earth & Environment, researchers led by first author Joely Maak from MARUM, University of Bremen tracked the #CarbonCycle in a specific marine ecosystem. Find out more ➡️ https://www.marum.de/en/ancient-carbon.html
