Oxygen concentrations in both the open ocean and coastal waters have declined by 2-5% since at least the middle of the 20th century.

The Arctic is melting faster than we thought it would. In fact, Arctic ice extent is at a record low. When that happens—when a natural system behaves differently than scientists expect—it’s time to take another look at how we understand the system.

Every spring, tens of thousands of elk follow a wave of green growth up onto the high plateaus in and around Yellowstone and Grand Teton national parks, where they spend the summer calving and fattening on fresh grass. 

NASA’s Terra satellite showed Tropical Cyclone Vayu still lingering near the northwestern coast of India, and its cloud-filled eye remained offshore.

Mainstream strategies generally address the challenge of reducing carbon by reviewing consumption, but a complementary approach looks at how people spend their time.

A better understanding of terrestrial flux dynamics will come from elucidating the integrated effects of climate and vegetation constraints on gross primary productivity (GPP), ecosystem respiration (ER), and net ecosystem productivity (NEP), according to Dr. CHEN Shutao, Associate professor at Nanjing University of Information Science and Technology.

Finding a shady refuge to cool off on a hot day could be more than a lifesaver in a warming world.

NASA’s Terra satellite showed Tropical Cyclone Vayu still lingering near the northwestern coast of India, and its cloud-filled eye remained offshore.

Climate and ecosystems are changing, but predation on shorebird nests has changed little across the globe over the past 60 years, finds an international team of 60 researchers.

New analysis of NOAA’s long-term air samples by NOAA and CIRES scientists finds that the North American terrestrial biosphere takes up unexpectedly large amounts of carbon in response to elevated carbon dioxide levels during El Niño years.
