Ocean heatwaves are breaking Earth’s hidden climate engine
Marine heatwaves can jam the ocean’s natural carbon conveyor belt, preventing carbon from reaching the deep sea. Researchers studying two major heatwaves in the Gulf of Alaska found that plankton shifts caused carbon to build up near the surface instead of sinking. This disrupted the ocean’s ability to store carbon for millennia and intensified climate feedbacks. The study highlights the urgent need for continuous, collaborative ocean observation.

Typhoon Tracks Regulated by Feedbacks of Fine-Scale Clouds to Environment
Accurate tropical cyclone (TC) track prediction is crucial for mitigating the catastrophic impacts of TCs on human life and the environment. Despite decades of research on tropical cyclone (TC) track prediction, large errors known as track forecast busts (TFBs) occur frequently, and their causes remain poorly understood. Here, we examine a few dozens of TCs using a unique TC downscaling strategy that can quantitatively assess the sensitivity of TC track on the strength of feedbacks of fine-scal…

Heterogeneous immune recovery after viral response through a dynamical model of feedback-driven persistence and clearance
Viral infections trigger complex immune responses with heterogeneous outcomes shaped by nonlinear feedbacks. An ordinary differential equation model is developed to investigate immune response dynamics during viral infection, incorporating six modules: viral load, innate immunity, cellular immunity, humoral immunity, immune suppression, and IL-6 levels. Bifurcation analysis reveals that under continuous viral exposure, when viral clearance rate and intrinsic viral death rate satisfy specific co…

When Simple is Enough, Binary Models Capture Social Complexity in Coupled Human-Environment Systems
Models of coupled human-environment systems often face a tradeoff between realism and tractability. Spectrum opinion models, where social preferences vary continuously, offer descriptive richness but are computationally demanding and parameter-heavy. Binary formulations, in contrast, are analytically simpler but raise concerns about whether they can capture key socio-ecological feedbacks. Here we systematically compare binary and spectrum social models across four benchmark settings: (i) replic…
