We're halfway through our Kaggle competition runtime, with 148 submissions so far! Despite using the same training data (1980-2020), submitted data-driven yield projections vary widely (median and interquartile range plotted). Try it for yourself: www.kaggle.com/competitions...

Line graph of mean maize and wheat yield in highly harvested areas from 1980 to 2100. After 2020, lines are projections based on training ML models on data from previous years, and wide error bars show high variance between these projections.

Can you learn from the past to predict future climate impacts? Our Kaggle competition has been running for 3 weeks, with 45 submissions so far. Despite using the same training data, models vary in their projected changes in global maize productivity... www.kaggle.com/competitions...

Line graph of modelled changes to maize productivity from 2020 to 2100. Most projections range from 0% to -20% at end-of-century, but some go down to -100%.

I've added a public notebook that trains a simple tree-based model and submits predictions to our Kaggle competition, to make it even easier to participate - just make a copy of the notebook and play around! www.kaggle.com/competitions...

Can we learn from the recent past to predict future climate change impacts using machine learning? We have created a new benchmark dataset designed to help answer this question, and you can take part in the challenge: www.kaggle.com/competitions...

A preprint I’ve been working on together with Olivier Pasche, Zhongwei Zhang, @zscheischlerjak.bsky.socialarxiv.org/abs/2404.17652. We compared ML-based weather models and ECMWF’s HRES in case studies on 3 recent high-impact extreme events! Summary & a few thoughts 🧵👇
