Soil is the foundation of our food systems, and sustainable farming depends upon healthy soil, which has impacts far beyond the field on air, water and climate. Wind and water, hastened by human activity and climate change, erode the richest soil at the surface.

The 2021 Atlantic hurricane season starts today, June 1. At NASA, we’re developing new technology and missions to study storm formation and impacts, including ways to understand Earth as a system.

A Flash Drought Dries the Southeast

After a wet spring in the eastern United States, a quick-onset drought has parched fields. The maps show Evaporative Stress Index (ESI) data, a drought indicator based on observations of land surface temperatures from National Oceanic and Atmospheric Administration geostationary satellites and on observations of leaf area index from NASA’s Terra and Aqua satellites and the Visible Infrared Imaging Radiometer Suite (VIIRS) on Suomi NPP. The combination makes it possible to gauge evapotranspiration—how much water is evaporating from the land surface and from the leaves of plants.
