Arctic ‘shorefast’ sea ice threatened by climate change, study finds

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.

Space laser missions map 16 years of ice sheet loss

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.

Glacier Detachments: A New Hazard in a Warming World?

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

Big data reveals we’re running out of time to save environment and ourselves

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.

Climate change may push some species to higher elevations — and out of harm’s way

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.

Researchers explore ocean microbes’ role in climate effects

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.

North pole soon to be ice free in summer

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

Melting ice reveals lost viking artefacts on mountain pass

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

Volcanic CO2 emissions helped trigger Triassic climate change

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

‘A bad time to be alive’: Study links ocean deoxygenation to ancient die-off

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 rapidly changing Arctic

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.

Climate change forced earlier colonisation of South Pacific Islands

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