Weather forecast reliability at risk from US climate data cuts
Experts warn that the Trump administration's 40% budget cuts to Noaa and reduced weather data collection could undermine the reliability of AI-powered weather forecasts, particularly for extreme weather events that cause hundreds of billions in annual damages. Research shows AI weather models already underperform at forecasting record-breaking weather events compared to traditional physics-based models.
What happened
The National Oceanic and Atmospheric Administration launched AI-powered global weather forecast models in late 2025, trained with centuries of weather data to improve forecast speed, efficiency and accuracy. The Trump administration proposed a 40% budget cut to Noaa overall in 2026, while climate and weather data collection has declined. Staffing cuts have forced the National Weather Service to scale back satellite and weather balloon launches, key parts of the country's data collection system, and shrunken climate programs threaten ocean buoy networks and other observation systems.
Reported impact
Experts warn that cuts to climate and weather data collection could make the federal government's weather forecasts less reliable when they are needed most as the US prepares for hurricane season and record-breaking heat. Research indicates AI models underperform in forecasting record-breaking extreme weather events, underestimating both the frequency and intensity of such events, which drive hundreds of billions of dollars in damages annually through destroyed cropland, infrastructure impacts and loss of human life.
Index analysis
AI is a valuable tool for weather prediction only when trained with ample data, according to former Noaa officials. Traditional physics-based models continue to outperform AI models at forecasting extreme weather events, according to research published in Science Advances.
Governance controls
The National Weather Service stated that a wealth of weather data is collected daily from satellites, weather balloons, ocean buoys and land-based sensors, disputed by widespread reports of staffing cuts forcing reductions in satellite and balloon launches.
