It is tempting to view the capability of current AI technology as a singular quantity: either a given task X is within the ability of current tools, or it is not. However, there is in fact a very wid...

weather forecasting models (trained on present-day data) provide skillful forecasts also in different colder and warmer states of the climate system? Our preprint in arxiv explores this question:

Robustness of AI-based weather forecasts in a changing climate
Data-driven machine learning models for weather forecasting have made transformational progress in the last 1-2 years, with state-of-the-art ones now outperforming the best physics-based models for a ...

The storyline approach isnโt new, but for the first time, weโre using it with 10km resolution! ๐ See how extreme events might have looked in the past, without climate change, and how they could unfold in a +2ยฐC future. Check out our work led by Amal John:
