It seems like artificial intelligence is coming for yet another corner of human expertise—this time, the weather.
Google’s DeepMind, the tech giant’s London-based AI research lab, has unveiled a new weather forecasting model, GenCast, that’s reportedly setting a new standard for precision and speed. The claim? GenCast can churn out 15-day forecasts in just eight minutes, outperforming even the European Centre for Medium-Range Weather Forecasts (ECMWF), the gold standard in meteorology. If this pans out, it could be a game-changer for weather predictions, especially as extreme weather events become more frequent and severe.
On the surface, this all sounds like a win. Who wouldn’t want more accurate weather forecasts delivered in a fraction of the time? GenCast has been tested against real-world scenarios from 2019 and apparently outperformed the ECMWF in over 97% of cases. That’s impressive, and DeepMind is eager to tout its potential to save lives, avert disasters, and reduce economic damage. Given the tragic consequences of recent extreme weather events, like the Hawaiian wildfires and Hurricane Helene, better forecasting tools are more than welcome.
But let’s not get ahead of ourselves. While GenCast’s capabilities are undeniably impressive, there’s a bigger picture here that’s worth scrutinizing. For one, this isn’t just about predicting the weather—it’s about control, and when Big Tech steps into fields as critical as meteorology, it raises serious questions about centralization and accountability.
Google, a company that already has its fingers in countless pies, now wants to position itself as the go-to for weather forecasting. Considering its track record of wielding disproportionate influence in tech, commerce, and even politics, is it really wise to let one of the world’s most powerful corporations dictate how governments and agencies respond to natural disasters? Sure, DeepMind says this is all about saving lives, but let’s not kid ourselves: there’s big money to be made in controlling the flow of critical information.
Then there’s the issue of reliability. As much as AI promises to revolutionize weather prediction, it’s still dependent on existing models, like those run by ECMWF, for its training. GenCast was fed data spanning four decades, but weather is inherently unpredictable. Can a machine truly account for all the chaotic variables at play? And what happens when an algorithm inevitably gets it wrong? Who’s accountable when lives and resources are on the line?
Another layer of skepticism comes from the inevitable politicization of weather. Climate change, for instance, has become a rallying cry for policymakers, often in ways that push dubious regulations or costly “green” initiatives. With AI-driven forecasts potentially shaping public opinion and government policy, will these tools remain objective? Or will they, like so many other aspects of Big Tech, become instruments for a particular agenda?
DeepMind’s Florence Rabier describes GenCast as a “first step” toward integrating AI into weather forecasting. That’s fair. But let’s make sure that step doesn’t turn into a giant leap over common sense. Weather forecasting isn’t just a scientific challenge—it’s a matter of public trust. And when Big Tech starts controlling the narrative, it’s wise to keep one eye on the sky and the other on Silicon Valley.

For now, we can cautiously celebrate GenCast’s potential while staying vigilant. After all, accurate forecasts are great—just as long as they don’t come with strings attached.
