Because sea ice is at its lowest point in 1,500 years, scientists are questioning how ecological communities in the Arctic will be affected by this continued and perhaps accelerating melting process over the next two decades.
Last week's pictures from the North Pole Experimental Observatory showed pools of polar sea water, but experts say they aren't "particularly extreme."
During the Pliocene Epoch, the Earth was substantially warmer than it is today, despite similar concentrations of carbon dioxide in the atmosphere. A new study, led by the University of Colorado Boulder, suggests year-round ice-free conditions across the surface of the Arctic Ocean could explain the difference.
Scientists reported in the journal Scientific Reports that permafrost in a section of Antarctica is melting faster than expected.
Surface meltwater draining through cracks in an ice sheet can warm the sheet from the inside, softening the ice and letting it flow faster, a new NASA-funded study finds.
Large stretches of ice on the coasts of Antarctica and Greenland are at risk of rapidly cracking apart and falling into the ocean in events over the coming decades that could aggravate sea level rise.
A large team of international researchers has looked millions of years into the Antarctic past and found evidence that massive sections of the continent's eastern ice sheet once melted to raise sea levels by around 66 feet.
Lakes often form on top of a glacier and drain onto the bedrock below, lubricating a glacier's movements as a result. A new study from an international group of researchers has found the way these lakes drain can affect the velocity, extent and direction of a glacier's progress.
According to a new study published in the Proceedings of the National Academy of Sciences, the greenhouse gases emitted today will cause the sea level to rise for centuries to come. It is estimated each degree of global warming will raise sea levels by more than two meters.
The Columbia Plateau ecoregion is a Level III ecoregion designed by the United States Environmental Protection Agency in the U.S. states of Oregon and Washington, with little areas over the Washington state border in Idaho. This ecoregion stretches across a wide swath of the Columbia River Basin from the Dalles, Oregon to Lewiston, Idaho to Okanogan, Washington near the Canadian border. It incorporates nearly 500 miles of the Columbia River, as well as the lower reaches of major tributaries....
The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...
Meltwater is water that is released from melting snow or ice. This includes meltwater from glacial ice and ice shelves over oceans. Meltwater is often produced during volcanic eruptions, and can cause dangerous lahars (landslides of wet volcanic debris). When meltwater pools on the surface rather than draining or flowing away, it forms pools known as melt ponds. Meltwater will often refreeze as the temperature drops. Meltwater can also collect or melt under the ice's surface. Sub-glacial...
