In a first, a space mission led by NASA and France tracked Earth’s rivers swelling and shrinking from month to month over the course of a year and found significantly less of a swing than previous model-based estimates. A record drought in the Amazon likely influenced the tally made by the Surface Water and Ocean

Each year, the world’s leading climate scientists evaluate the most critical evidence on how our planet is changing. Their assessments draw heavily on data from Earth-observing satellites—and the latest 10 New Insights in Climate Science report delivers a stark warning: the planet’s energy balance is drifting further out of alignment, oceans are warming at unprecedented rates, and the

In the wake of a winter storm that blanketed numerous U.S. states with snow and ice, unusually low temperatures gripped a large swath of the nation east of the Rockies in late January 2026. The cold spell was notable for severity, longevity and geographic scope. This image compares surface air temperatures across part of the

The European Space Agency’s innovative Biomass satellite is now fully commissioned, opening free access to a powerful new stream of data that promise a step change in our understanding of forest dynamics and their role in regulating the global carbon cycle. This image from the Biomass mission depicts a transect of estimated forest carbon content, in tonnes

Science teams at NASA and the French space agency Centre National d’Études Spatiales (CNES) have released the first-ever global estimate of river discharge and suspended sediment, as observed from space, marking a new milestone in our ability to understand one of Earth’s most fundamental systems. Developed using data from the Surface Water and Ocean Topography

Satellites are emerging as a powerful new tool in the fight to curb emissions of methane. While methane is much shorter-lived in the atmosphere than carbon dioxide, it’s vastly more potent at trapping heat, which makes rapid cuts essential for slowing warming in the short-term. The same satellite technology that has transformed methane monitoring in

While continental in scale, the ozone hole over the Antarctic was small in 2025 compared to previous years and remains on track to recover later this century, NASA and the National Oceanic and Atmospheric Administration (NOAA) reported. The hole this year was the fifth smallest since 1992, the year a landmark international agreement to phase

Across the world’s oceans, including U.S. territorial waters, some vessels deliberately “go dark,” switching off AIS (cooperative beacon) to operate undetected. These actions can mask illegal fishing, pollution or non-compliant operations, posing risks to maritime safety, fair competition and environmental security. With its constellation of 17 satellites, Unseenlabs detects radiofrequency (RF) emissions from ships’ onboard electronics, enabling

The new Copernicus Sentinel-4 mission has delivered its first images, highlighting concentrations of atmospheric nitrogen dioxide, sulphur dioxide and ozone. Despite being preliminary, these images mark a major milestone in the ability to monitor air quality all the way from geostationary orbit, 36,000 kilometers above Earth. This image depicts tropospheric nitrogen dioxide with clear pollution hotspots visible

Driven by wind, waves are at their most powerful during storms, yet the greatest threat to coastlines often does not come from the storm itself, but from the long swells that carry wave energy far beyond the storm’s reach. These long waves radiate across oceans, and their properties—such as wave period, or the time between
