Climate Change

For people who live in the Arctic, sea ice that forms along shorelines is a vital resource that connects isolated communities and provides access to hunting and fishing grounds.

Using the most advanced Earth-observing laser instrument NASA has ever flown in space, scientists have made precise, detailed measurements of how the elevation of the Greenland and Antarctic ice sheets have changed over 16 years.

A startling event occurred deep in the remote interior of the United States’ largest national park.

The use of big data can help scientists' chart not only the degradation of the environment but can be part of the solution to achieve sustainability, according to a new commentary paper.

A new WCS-led study reveals that mountain-dwelling species fleeing warming temperatures by retreating to higher elevations may find refuge from reduced human pressure.

A new study shows that "hotspots" of nutrients surrounding phytoplankton -- which are tiny marine algae producing approximately half of the oxygen we breathe every day -- play an outsized role in the release of a gas involved in cloud formation and climate regulation.

The Arctic Ocean in summer will very likely be ice-free before 2050, at least temporally.

In Norway, hundreds of rare archaeological finds have been revealed by melting ice in a lost mountain pass at Lendbreen in Innlandet County.

Study offers sobering warning on the impact of rising carbon dioxide levels in the atmosphere.

In a new study, Stanford researchers have strongly bolstered the theory that a lack of oxygen in Earth's oceans contributed to a devastating die-off approximately 444 million years ago.

A new study by researchers at Woods Hole Oceanographic Institution (WHOI) and their international colleagues found that freshwater runoff from rivers and continental shelf sediments are bringing significant quantities of carbon and trace elements into parts of the Arctic Ocean via the Transpolar Drift--a major surface current that moves water from Siberia across the North Pole to the North Atlantic Ocean.

Research led by scientists at the University of Southampton has found settlers arrived in East Polynesia around 200 years earlier than previously thought.
