Study shows today’s atmospheric carbon dioxide levels greater than 23 million-year record

A common message in use to convey the seriousness of climate change to the public is: "Carbon dioxide levels are higher today than they have been for the past one million years!"

Higher Sea Level Rise Predicted by Melting Ice Sheets

A new study by the Nanyang Technological University has been studying melting polar ice sheets and predicts that ocean levels will rise by as much as 1.3 metres by 2100.

ICESat-2 measures arctic ocean’s sea ice thickness, snow cover

Arctic sea ice helps keep Earth cool, as its bright surface reflects the Sun's energy back into space. Each year scientists use multiple satellites and data sets to track how much of the Arctic Ocean is covered in sea ice, but its thickness is harder to gauge.

Almost Half of World Heritage Sites Could Lose Glaciers by 2100

The study combines data from a global glacier inventory, a review of existing literature and computer modeling to analyze World Heritage glaciers.

Oceans should have a place in climate ‘green new deal’ policies, scientists suggest

The world's oceans play a critical role in climate regulation, mitigation and adaptation and should be integrated into comprehensive "green new deal" proposals being promoted by elected officials and agency policymakers, a group of ocean scientists suggests in a new paper.

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.
