Upwelling in the Equatorial Pacific nurtures an expansive, westward-stretching chlorophyll-rich tongue (CRT), supporting 18% of the annual global new production. Surrounding the CRT are the oligotrophic subtropical gyres to the north and south, which are suggested to be expanding under global warming. Yet, how this productive CRT has changed, expanding or contracting, remains unknown.

In 2023, the CO growth rate was 3.37 ± 0.11 ppm at Mauna Loa, which was 86% above that of the previous year and hit a record high since observations began in 1958, while global fossil fuel CO emissions only increased by 0.

The concentration of near-surface Beryllium-7 contains valuable information about the atmosphere, e.g., the tropospheric circulation, precipitation pattern or specific atmospheric phenomena, like the El Niño Southern Oscillation.

However, the current estimation of wetland CH emissions at the global scale still has large uncertainties. Here we developed six distinct bottom-up machine learning (ML) models using in situ CH fluxes from both chamber measurements and the Fluxnet-CH network.
