NASA will launch four Earth science missions in 2022 to provide scientists with more information about fundamental climate systems and processes including extreme storms, surface water and oceans, and ...

Every month on Earth Matters, we offer a puzzling satellite image. The December 2024 puzzler is shown above. Your challenge is to use the comments section to tell us where it is, what we are looking ...

NASA satellites and sensors constantly take the pulse of our planet, measuring how Earth changes by the day, season, year, and decade. Researchers and resource managers analyze those measurements and ...

A saguaro cactus (Carnegiea gigantca) has a smooth, waxy skin that seals in moisture. Cacti expand by absorbing water when it is available and shrink as they lose water slowly during times of drought.

In Earth’s history before the Industrial Revolution, Earth’s climate changed due to natural causes not related to human activity. Most often, global climate has changed because of variations in ...

Scientists have used a variety of methods to survey the world’s forests and their biomass. They have systematically measured forests from the ground, venturing into the woods to count trees, measure ...

The Antarctic is in some ways the opposite of the Arctic. The Arctic is an ocean basin surrounded by land, with the sea ice corralled in the coldest, darkest part of the Northern Hemisphere. The ...

All matter in the universe that has a temperature above absolute zero (the temperature at which all atomic or molecular motion stops) radiates energy across a range of wavelengths in the ...

Whereas aerosols can influence climate by scattering light and changing Earth’s reflectivity, they can also alter the climate via clouds. On a global scale, these aerosol “indirect effects” typically ...

Despite the accuracy and importance of the information gleaned from the North Carolina coastline, Wright almost seems to regret he couldn’t track damage in more complicated coastal regions. If Isabel ...

The water, or hydrologic, cycle describes the pilgrimage of water as water molecules make their way from the Earth’s surface to the atmosphere and back again, in some cases to below the surface. This ...
