Applications of AI in climatology research

Further progress in AI+climate modeling "Applying the ACE2 Emulator to SST Green's Functions for the E3SMv3 Global Atmosphere Model". Building on ACE2 model which uses our spherical Fourier neural operator (SFNO) architecture, this work shows that ACE2 can replicate climate model responses to sea surface temperature perturbations with high fidelity at a fraction of the cost. This accelerates climate sensitivity research and helps us better understand radiative feedbacks in the Earth system. Background: The SFNO architecture was first used in training FourCastNet weather model, whose latest version (v3) has state-of-art probabilistic calibration. AI+Science is not just about blindly applying the standard transformer/CNN "hammer". It is about carefully designing neural architectures that incorporate domain constraints like geometry and multiple scales, while being expressive and easy to train. SFNO accomplishes both: it incorporates multiple scales, and it respects the spherical geometry and this is critical for success in climate modeling. Unlike short-term weather, which requires only a few autoregressive steps for rollout, climate modeling requires long rollouts with thousands or even greater number of time steps. All other AI-based models fail for long-term climate modeling including Pangu and GraphCast which ignore the spherical geometry. Distortions start building up at the poles since the models assume domain is a rectangle, and they lead to catastrophic failures. Structure matters in AI+Science!

At #COP29 this year, climate adaptation, and the role of technology to support with early warning systems, adaptation and resiliency was high on the agenda. One area Google has been working on for a number of years is using AI to help forecast riverine floods, and I'm excited about our recent expansion: 🌎 Expanding coverage of our AI-powered riverine flood forecasting model to 100 countries (up from 80) in areas where 700m people live (up from 460m). 🔮 An improved flood forecasting model — which builds upon our breakthrough model — that has the same accuracy at a seven-day lead time as the previous model had at five days. 📖 Making our model forecasts available to researchers and partners via an upcoming API and our Google Runoff Reanalysis & Reforecast (GRRR) dataset. 👐 Providing researchers and experts with expanded coverage — based on “virtual gauges” for locations where data is scarce — via an upcoming API, the GRRR dataset, as well a new expert data layer on Flood Hub with close to 250,000 forecast points of our Flood Forecasting model, spread over 150 countries. 🕰️ Making historical datasets of our flood forecasting model available, to help researchers understand and potentially reduce the impact of devastating floods.

In this week's column, I look at NVIDIA's new generative foundation model that it says enables simulations of Earth’s global climate with an unprecedented level of resolution. As is so often the case with powerful new technology, however, the question is what else humans will do with it. The company expects that climate researchers will build on top of its new AI-powered model to make climate predictions that focus on five-kilometer areas. Previous leading-edge global climate models typically don’t drill below 25 to 100 kilometers. Researchers using the new model may be able to predict conditions decades into the future with a new level of precision, providing information that could help efforts to mitigate climate change or its effects. A 5-kilometer resolution may help capture vertical movements of air in the lower atmosphere that can lead to certain kinds of thunderstorms, for example, and that might be missed with other models. And to the extent that high-resolution near-term forecasts are more accurate, the accuracy of longer-term climate forecasts will improve in turn, because the accuracy of such predictions compounds over time. The model, branded by Nvidia as cBottle for “Climate in a Bottle,” compresses the scale of Earth observation data 3,000 times and transforms it into ultra-high-resolution, queryable and interactive climate simulations, according to Dion Harris, senior director of high-performance computing and AI factory solutions at Nvidia. It was trained on high-resolution physical climate simulations and estimates of observed atmospheric states over the past 50 years. It will take years, of course, to know just how accurate the model’s long-term predictions turn out to be. The The Alan Turing Institute of AI and the Max Planck Institute of Meteorology, are actively exploring the new model, Nvidia said Tuesday at the ISC 2025 computing conference in Hamburg. Bjorn Stevens, director of the Planck Institute, said it “represents a transformative leap in our ability to understand, predict and adapt to the world around us.” The Earth-2 platform is in various states of deployment at weather agencies from NOAA: National Oceanic & Atmospheric Administration in the U.S. to G42, an Abu Dhabi-based holding company focused on AI, and the National Science and Technology Center for Disaster Reduction in Taiwan. Spire Global, a provider of data analytics in areas such as climate and global security, has used Earth-2 to help improve its weather forecasts by three orders of magnitude with regards to speed and cost over the last three or four years, according to Peter Platzer, co-founder and executive chairman.

A key goal of our research is to drive scientific breakthroughs and translate them into real-world impact. Our AI-based long-range weather forecasting model, NeuralGCM is helping 38 million farmers in India make more informed decisions about the monsoon season. This initiative, led by the University of Chicago and the Indian Ministry of Agriculture and Farmers’ Welfare, is a good manifestation of this goal. Here is how this work is helping farmers: ➡️ Forecasting models Accurate, long-range monsoon forecasting has been a persistent challenge. AI-driven models like NeuralGCM learn from decades of historical data, which makes them efficient to run and provides crucial insights at a local scale. ➡️ Impact  Research from the University of Chicago indicates that accurate forecasts can significantly increase a farmer's annual income by almost doubling it. Some examples from the study show:  👨🌾 for farmers who received a forecast that the monsoon would be later than they expected, the new information helped them make alternative plans, leading to net savings of over $560 per farmer. 👨🌾 For farmers who received "good news" that the growing season would be longer than expected, increased investments and expenditures forecast, which led to 22 % increases in agricultural production. This project is an example of how foundational research can be open-sourced and leveraged by the community to create solutions that directly benefit communities at scale - putting AI to work on real-world problems.

We know the Earth is getting warmer, but not what it means specifically for different regions. To figure this out, scientists do climate modelling. 🔎 🌍 , Google Research has published groundbreaking advancements in climate prediction using the power of #AI! Typically, researchers use "climate modelling" to understand the regional impacts of climate change, but current approaches have large uncertainty. Introducing NeuralGCM: a new atmospheric model that outperforms existing models by combining AI with physics-based modelling for improved accuracy and efficiency. Here’s why it stands out: ✅ More Accurate Simulations When predicting global temperatures and humidity for 2020, NeuralGCM had 15-50% less error than the state-of-the-art model "X-SHiELD". ✅ Faster Results NeuralGCM is 3,500 times quicker than X-SHiELD. If researchers simulated a year of the Earth's atmosphere with X-SHiELD, it would take 20 days to complete —  whereas NeuralGCM achieves this in just 8 minutes. ✅ Greater Accessibility Google Research has made NeuralGCM openly available on GitHub for non-commercial use, allowing researchers to explore, test ideas, and improve the model’s functionality. The research showcases AI’s ability to help deliver more accurate, efficient, and accessible climate predictions, which is critical to navigating a changing global climate.

AI has the potential to bring new waves of innovation, social and economic progress on a scale we’ve not seen before - including supercharging scientific progress. This week, Google published NeuralGCM: an openly available tool for fast, accurate climate modelling - critical to a changing global climate. We know that the Earth is getting warmer, but it’s hard to predict what that means for each different region. To figure this out, scientists use climate modelling. But current approaches have large uncertainty, including systematic errors - like forecasting extreme rain that is only half as intense as what scientists actually observe. That’s where NeuralGCM comes in. It combines physics-based modelling and AI to simulate the Earth’s atmosphere - making it faster and more accurate than existing climate models. For scientists exploring how to build better weather and climate models, it should make a huge difference in helping them understand the effects of the climate crisis on our world - and it could also be great for meteorologists making predictions about our daily weather!

Clouds block satellites. AI fills in the gaps. And, suddenly, we’re better at predicting typhoons. A new system called PARAN is helping scientists see the ocean more clearly—literally. When clouds get in the way of satellite readings, this AI model steps in to reconstruct sea surface temperature data in real time. That means better insight into how heat moves between the ocean and atmosphere… and way better forecasting of heatwaves, storms, and marine disasters. It’s a smart blend of AI and physics, and a huge leap for climate resilience. Because when you can’t see the problem, you definitely can’t solve it. Science, meet sharp vision. #ClimateTech #AI
