Subsidence, or the sinking of land, threatens the U.S. Gulf Coast, where millions face growing flood risks from sea-level rise. Measuring the subsidence is essential for coastal planning and climate adaptation. Satellite radar (InSAR) is widely used to measure subsidence, but studies often disagree. Comparing two recent datasets, we found widespread disagreements except in dense urban areas. Decision makers should use coastal InSAR products with caution until these discrepancies are resolved.

Antarctic ice shelves help slow ice flow into the ocean, but their stability depends partly on the upper firn layer. Air in firn affects how much meltwater can be stored, while grain size helps describe firn structure. We combined fifteen years of satellite radar data with physical models to estimate these properties across Antarctic ice shelves. Our results provide a new way to monitor conditions linked to meltwater build-up and possible instability.

Land and sea surface temperatures, collectively called skin temperature (Tskin), are available from satellite measurements since few decades now and provide a holistic view of the Earth's climate system. Here we review 6 different datasets of Tskin to show that climate change signature is clear from the different datasets with notable exception, such as a significant cooling in India, parts of Africa and the Pacific.

This study combines earth observation indicators and farmer survey data collected in four rice-growing states in Nigeria to assess drought impacts on rainfed rice yields. We use regression models to connect meteorological indices and earth observation indicator anomalies to identify drought moments over the years 2020–2024, demonstrating that indicator anomalies are correlated to rice yield changes, particularly when anomaly values are aggregated temporally over separate rice growth stages.
