Arctic Coastal Sea Ice Thinning Twice as Fast Than Thought
Frequently in the news, Earth’s declining ice is without doubt one of the biggest casualties of climate change. However, calculating the amount of ice we are losing can be a challenge. While monitoring the area of land and ocean covered by ice is relatively straightforward using images from satellites carrying camera-like instruments, scientists need to
The rate at which plants and the land surface release moisture into the air has increased on a global scale between 2003 and 2019. These processes are collectively known as evapotranspiration, and a new NASA study has calculated its increase by using observations from gravity satellites. By gauging the mass change of water between the

Soil Data Aids Prediction of Locust Swarms
In 2019-2020, eastern Africa experienced its worst desert locust invasion in more than 40 years. The United Nations and its partners treated more than 17,000 square kilometers (6,600 square miles) of locust infestations across 10 countries with various eradication methods. Countless crops were still devoured by the insects, causing serious food insecurity in the region.
In a decade filled by record-breaking events, including raging wildfires, numerous hurricanes, unseasonal flooding and historically cold temperatures, NASA has continued to learn more about how the planet is changing and the effect it has on Earth’s systems. In the satellite era, a fleet of Earth-observing satellites have gathered data on worldwide rain and snowfall,
