Local weather plays an important part in the retreat of the ice shelves in West Antarctica, according to new research.
New research findings explain an Ice Age paradox and add to the mounting evidence that climate change could bring higher seas than most models predict.
Based on data from the first ocean sensors deployed under Greenland's Petermann Glacier, researchers report that the floating ice shelf is strongly coupled, or tied, to the ocean below and to the adjacent Nares Strait. Warming temperatures recorded at the deepest ocean sensors match data from Nares Strait, which connects the Arctic and Atlantic oceans.
Cracks in the Greenland Ice Sheet let one of its aquifers drain to the ocean, new NASA research finds. The aquifers, discovered only recently, are unusual in that they trap large amounts of liquid water within the ice sheet. Until now, scientists did not know what happened to the water stored away in this reservoir -- the discovery will help fine tune computer models of Greenland's contribution to sea level rise.
The possibility of major climate change in the Atlantic region has long been recognized and has even been the subject of a Hollywood movie: The Day After Tomorrow. To evaluate the risk of such climate change, researchers developed a new algorithm to analyze the 40 climate models considered by the latest report from the Intergovernmental Panel on Climate Change (IPCC). Their findings raise the probability of rapid North Atlantic cooling during this century to nearly 50%.
Ice loss from Canada's Arctic glaciers has transformed them into a major contributor to sea level change, new research has found. From 2005 to 2015, surface melt off ice caps and glaciers of the Queen Elizabeth Islands grew by an astonishing 900 percent.
Surprising new evidence derived from ancient ceramics proves that the Earth's geomagnetic force fluctuates -- not diminishes -- over time, researchers say.
How will future climate change affect our glaciers? By looking into the past 4000 years, a new study finds an ice cap in southern Norway to be ‘exceptionally sensitive’ to climate change.
Researchers found sunlight converted little if any permafrost thawed carbon to carbon dioxide, whereas microbes were shown to rapidly convert permafrost carbon to carbon dioxide.
The Arctic has a serious litter problem: in just 10 years, the concentration of marine litter at a deep-sea station in the Arctic Ocean has risen 20-fold, according to researchers.
Sea level in Southeast Asia fluctuated wildly -- and naturally -- more than 6,000 years ago, twice rising nearly two feet in a period of about 200 years, report researchers.
Less than a year after the first research flight kicked off NASA's Oceans Melting Greenland campaign, data from the new program are providing a dramatic increase in knowledge of how Greenland's ice sheet is melting from below.
A recent interpretive review of scientific literature sheds light on the interactions of gas hydrates and climate.
With the ocean absorbing more carbon dioxide over the past decade, less of the greenhouse gas is reaching the Earth's atmosphere. That's decidedly good news, but it comes with a catch: Rising levels of carbon dioxide in the ocean promote acidification, which breaks down the calcium carbonate shells of some marine organisms.
Drainage of four interconnected lakes below Thwaites Glacier in late 2013 caused only a 10 percent increase in the glacier's speed. The glacier's recent speedup is therefore not due to changes in meltwater flow along its underside.
In the beginning, planet Earth was a very inhospitable place with no oxygen and only single-celled bacteria as inhabitants. According to a new study, the oxygen content in the air began to increase about 2.4 billion years ago, at the same time as the global glaciation and when all continents were gathered in a single huge landmass, or supercontinent. How to explain the exact connection between these events, however, is a question that baffles the researchers.
A 'Snowball Earth' event actually took place 100 million years earlier than previously projected, outlines a new report.
Transport and residential heating could be responsible for a greater contribution of black carbon in the Russian Arctic compared to gas flaring or power plants, according to new research.
Tiny air bubbles compressed within a polar ice core make some sections brittle to the touch, but one ice core lab knows how to handle this delicate part of the chemical analysis, thus making the dating of the entire ice core possible.
Dust released by an active coal mine in Svalbard, Norway, reduced the spectral reflectance of nearby snow and ice by up to 84 percent, according to new research.
