Today’s Highlights

A neural network emulator (Neural-BGC) coupled to the Regional Ocean Modeling System reproduces observed biogeochemical patterns—including oxygen minimum zones and coastal nutrient fronts—and outperforms a tuned NPZD model across contrasting upwelling regimes, opening an efficient path for data-driven ocean BGC modeling. On the terrestrial side, a US-wide forest inventory analysis shows that compound heat–drought extremes exert synergistic negative impacts stronger than the sum of individual extremes, but higher tree diversity consistently improves both resistance and recovery. A BAMS essay rounds out the day by exploring how co-producing ethno-climatological knowledge with National Meteorological and Hydrological Services can strengthen climate adaptation in agriculture.

Neural‐BGC: An Observation‐Driven Emulator for Hybrid Physical‐Biogeochemical Modeling

Authors: Said Ouala, Zouhair Lachkar

Journal: Geophysical Research Letters · DOI: 10.1029/2026gl123123

Matched topics: seasonal, coastal

Coupled ocean‐biogeochemical models are essential for understanding marine ecosystems, yet they often suffer from persistent biases due to poorly constrained empirical parameters. To address this limitation, we introduce Neural‐BGC, an observation‐driven neural network emulator for hybrid physical‐biogeochemical modeling. Neural‐BGC is trained on quality‐controlled ocean profiles from the World Ocean Database. The model employs a cascaded architecture to predict dissolved oxygen and nitrate concentrations from physical state variables and spatiotemporal coordinates. We couple this emulator to the Regional Ocean Modeling System and evaluate the hybrid framework in two contrasting regions: the Arabian Sea and the Canary Current Upwelling. The hybrid model reproduces observed spatial patterns and seasonal variability, while capturing features such as oxygen minimum zones and coastal nutrient fronts. Notably, Neural‐BGC often outperforms a tuned NPZD model in simulating the mean biogeochemical state. This framework offers a computationally efficient, data‐driven alternative for high‐fidelity regional and global ocean BGC modeling.

Prospects for co-producing ethno-climatological knowledge (ECK) with National Meteorological and Hydrological Services (NMHS) information for agriculture

This essay provides an overview of the importance, challenges, and opportunities in co-producing ethno-climatological knowledge (ECK) with climate information generated by the National Meteorological and Hydrological Services (NMHSs). We bridge the gap between ECK holders and NMHSs by recognizing both forms of knowledge and highlighting the importance of transmitting and integrating ECK into agricultural adaptation and policy efforts. We propose a way forward to increase access to and use of readily available climate information. The essay is complemented with examples on climate folklore and presents approaches for the co-production of climate services in the agriculture sector. Throughout the essay, we emphasize the need to create dialogue spaces that build trust, ensure meaningful engagement, and foster mutual understanding where ECK holders are central in the co-production of climate services. The essay also calls for climate services and climate change adaptation actors to acknowledge and respect the unique value of ECK and to inform the ongoing dialogue on the urgency of integrating ECK into climate action.

Biodiversity buffers forest ecosystems from compound climate extremes

Forest ecosystems provide key ecological, social, and climate benefits, yet their functions are potentially threatened by rising compound extremes characterised by simultaneous heat and drought or moisture excess. Here, we explore how forests resist and recover from compound heat and moisture extremes and how tree diversity mediates these responses, using U.S. forest inventory data along with satellite-based stability estimates. We find that compound extremes result in lower forest resistance and recovery than individual extremes. Compound extremes tend to exhibit synergistic effects, causing greater negative impacts than the sum of individual extremes. Compound heat and drought have slightly stronger destabilising effects than compound heat and moisture excess. Higher tree diversity consistently improves resistance and recovery under both individual and compound extremes. Our findings suggest that focusing solely on individual climate extremes is likely to underestimate the impacts of compound extremes and to increase uncertainty in projections of terrestrial carbon-cycle feedbacks, while also highlighting the critical role of tree diversity in mitigating these threats under future climate conditions.
