Update: Carbon Dioxide Concentration
The global average concentration of atmospheric carbon dioxide (CO2) in October 2021 was about 417 parts per million (ppm), a nearly 49% rise since 1850 due to human activities, like the burning of fossil fuels. (The term "parts per million" refers to the number of carbon dioxide molecules per million molecules of dry air.)
NASA's Eyes on the Earth Puts the World at Your Fingertips
The 3D real-time visualization tool lets users track NASA satellites as well as the vital Earth science data they provide. Recent upgrades make for an even more fascinating experience.
NASA Selects New Mission to Study Storms, Impacts on Climate Models
Called INCUS, it aims to directly address why convective storms, heavy precipitation, and clouds occur exactly when and where they form.
NASA, USGS Release First Landsat 9 Images
The mission, which launched on Sept. 27, 2021, has collected its first images of Earth, providing a preview of how the satellite will help people manage vital natural resources and understand the impacts of climate change.
Earth Science in Action: Tracking Water in the Face of Drought
Climate change can make drought more severe in the U.S. West – but a new platform called OpenET is using NASA Earth data to help show farmers how much water their crops really need and inform decisions for water conservation efforts.
Images of Change: Cape Cod's Ever-Changing Coast
The southeastern coast of a Massachusetts peninsula changes constantly under the influence of currents, tides, waves, and storms. See how the North Beach area changed between 1984 and 2020, when the Patriot's Day storm in 2007 cut an inlet through it.
Images of Change: Record Low Water Level at Great Salt Lake, Utah
Over the last four years, the view from space has revealed declining water levels in the northern part of the Great Salt Lake, as well as a portion of the southern part. In July 2021, the southern portion in particular reached its lowest average daily level on record. Visit the link to learn what else changed in this body of water.
Images of Change: NASA Helps Peru Find Illegal Gold Mining
NASA and partners are helping Peruvian authorities stop illegal gold mining in the Amazon, focusing on finding small-scale operations, which often use toxic mercury and carve out larger environmental footprints than industrial mines. Satellite images show the spread of illegal gold mining along the Pariamanu River between May 30, 2020 and May 2, 2021.
