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.

Winter Heat Swamps Alaska

While much of the continental United States endured several cold snaps in January 2014, record-breaking warmth gripped Alaska. Spring-like conditions set rivers rising and avalanches tumbling.

This map depicts land surface temperature anomalies in Alaska for January 23-30, 2014. Based on data from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite, the map shows how 2014 temperatures compared to the 2001-2010 average for the same week. Areas with warmer than average temperatures are shown in red; near-normal temperatures are white; and areas that were cooler than the base period are blue. Gray indicates oceans or areas where clouds blocked the satellite from collecting usable data. Read more
