This new [article](https://doi.org/10.1175/JCLI-D-24-0258.1) explores the predictability of Antarctic sea ice, which varies by region and is influenced by ocean and atmospheric conditions. Using climate models, Marika Holland and co-authors, confirm that **sea ice changes can be predicted months in advance, with cycles of predictability linked to ice growth and retreat**: it remains predictable during growth, loses predictability when melting, and regains it as it reforms. Ocean temperature patterns near the ice edge play a key role, with variations across different regions. These ice changes also influence marine ecosystems by affecting light availability. Understanding these patterns can **improve climate predictions and support the management of the Southern Ocean’s biodiversity**.

Autoregressive surrogate models (emulators) make fast predictions for dynamical systems but become unstable over time due to error buildup. This [study](https://doi.org/10.48550/arXiv.2503.18731), led by Chris Pedersen, introduces thermalization, a technique leveraging diffusion models to adaptively correct errors during inference. **By stabilizing predictions, it extends emulated rollouts of chaotic and turbulent systems by several orders of magnitude**. This breakthrough application of diffusion models enhances the utility of emulators, and can be applied to autoregressive models across science and engineering.

A new framework from NCAR, called CREDIT (Community Research Earth Digital Intelligence Twin), is making it easier for researchers to **develop and test AI-based weather prediction models**. Introduced in this [paper](https://doi.org/10.1038/s41612-025-01125-6), CREDIT supports flexible model design and training, helping **address key challenges in AI-based forecasting**. Using this platform, researchers introduced WXFormer, a novel model that outperforms traditional forecasting systems like ECMWF’s IFS on 10-day forecasts, while being much more computationally efficient. CREDIT aims to accelerate innovation and collaboration in AI-driven weather prediction. **William Chapman** and **Judith Berner** contributed to this research.

**Gregory** et al. present in this [preprint](https://doi.org/10.48550/arXiv.2505.18328), a hybrid modeling approach that **integrates machine learning (ML) into the GFDL SPEAR climate model to correct sea ice biases in real time**. Two versions are tested: one that includes coupled feedbacks (HybridCPL) and one that does not (HybridIO). HybridCPL **significantly improves Arctic and Antarctic sea ice forecasts on seasonal and subseasonal timescales**. In contrast, HybridIO performs poorly due to unanticipated feedbacks. These results highlight the **importance of training ML models within coupled climate systems** for reliable predictions.

**Perezhogin** et al. propose in this [preprint](https://doi.org/10.48550/arXiv.2505.08900), a **physics-informed neural network to improve the generalization of data-driven mesoscale eddy parameterizations** in ocean models. By applying local input-output scaling based on dimensional analysis, **their method adapts to different grid resolutions and depths**. This approach enhances energy representation and affects biases in both idealized and global ocean simulations. The scaling framework is broadly applicable and robust across configurations. Results show **competitive performance compared to traditional parameterizations**.

A new [paper](https://doi.org/10.1029/2025GL114951), led by **Julius Busecke** and **Dhruv Balwada**, highlights how small-scale air-sea interactions, often unresolved in climate models, can **significantly influence large-scale heat exchange between the ocean and atmosphere**. Using high-resolution coupled simulations, researchers found that this small-scale variability leads to a **systematic global ocean cooling of about 4 W/m², with regional effects up to 100 W/m²**. These findings underscore the critical role of atmospheric wind and ocean temperature heterogeneity, offering new insights for improving climate model accuracy.

This [study](https://doi.org/10.48550/arXiv.2506.22552) examines fundamental challenges in using data-driven models, especially **neural networks, for simulating complex climate dynamics**. While these models can often reproduce average climate behavior, they struggle to capture responses to external changes. The author, **Fabrizio Falasca**, shows that this limitation becomes especially pronounced when only partial observations are available, a common scenario in real-world climate systems. His **findings highlight the importance of incorporating physically informed methods**, like coarse-graining and stochastic parameterizations, **to improve the accuracy and interpretability of neural climate emulators**.

This [study](https://doi.org/10.22541/essoar.174835313.30541637/v1), led by Dhruv Balwada, introduces a **new data-driven parameterization to better represent how mesoscale eddies remove potential energy from the ocean in climate models**. Unlike the widely used Gent-McWilliams (GM) scheme, which can hinder resolved eddies and lacks a robust basis for tuning, this approach is both **flow-aware and scale-aware, minimizing negative impacts on resolved dynamics**. Built with a lightweight neural network, the method is efficient, easy to implement, and successfully tested in NOAA’s MOM6 model. The results highlight a **promising path to reduce structural errors and improve the realism of climate simulations**.
