New research shows that as Earth’s climate is changing, increased carbon absorption by plants in the Arctic is being offset by a corresponding decline in the tropics.

Scientists have identified an unsettling trend – as levels of CO2 in the atmosphere increase, 86 percent of land ecosystems globally are becoming progressively less efficient at absorbing it.

In September and October, the Stratospheric Aerosol and Gas Experiment III (SAGE III) instrument aboard the International Space Station observed smoke from the ongoing wildfires using solar occultation, a measurement technique that involves looking at light from the Sun as it passes through Earth’s...

An international team of scientists has used artificial intelligence and commercial satellites to identify an unexpectedly large number of trees spread across arid and semi-arid areas.

Dune fields of interest to scientists who study the Red Planet stand out in the Kobuk Valley amid a backdrop of green.

Human-produced noise and light pollution is troublesome to our avian neighbors, according to new research from a team at California Polytechnic State University, published Nov. 11 in Nature.

A towering thunder cloud stands at the intersection of moist tropical air and dry, dusty plumes.

Tidal swings here are greater than at any other place on the east coast of Australia.

Seasonal cues, such as warmer spring temperatures or cooler temperatures in the fall, tell animals when to migrate, when to mate, and when and where to find food. Predators and prey, birds and mammals alike follow this natural schedule, and an overall shift of just a few days or weeks could have... Read More

Using computer models to generate a COVID-free 2020 for comparison, NASA researchers found that since February, pandemic restrictions have reduced global nitrogen dioxide concentrations by nearly 20%.

Scientists watch as A-68A, currently the planet’s largest iceberg, approaches a remote island in the southern Atlantic Ocean.

A new study tracing the sources of carbon dioxide, the most significant human-generated greenhouse gas, reveals the unexpectedly large influence of vegetation in urban environments.

NASA is targeting 12:17 p.m. EST (9:17 a.m. PST) Saturday, Nov. 21, for the launch of the Sentinel-6 Michael Freilich satellite, the first of two identical satellites to head into Earth orbit five years apart to continue sea level observations for at least the next decade.
