A new study found that fast-flowing and narrow glaciers could trigger massive changes in the Antarctic ice sheet, inevitably adding sea-level rise and ice-sheet decay.
As climate change tightens its grip on the polar regions, many biologists are investigating how different species that live there are being affected by increasing temperatures and decreasing polar ice.
New research, led by the University at Buffalo, is examining an important mystery surrounding climate change: How quickly do glaciers melt and grow in response to shifts in temperature.
A report, issued this week by the National Research Council (NRC) has concluded that glacial melt in the Eastern and Central Himalayas has accelerated at an alarming rate, while glaciers in the Western Himalayas may actually be growing. Researchers say that this trend could have both positive and negative consequences for local inhabitants and ecosystems.
As the end of the Arctic melt season ends with the region having already set new records for the smallest amount of sea ice extent and volume, experts this past weekend began to gauge exactly what the implications will be, both locally and throughout the rest of the world.
Much has been said lately about Arctic ice melting at an alarming and record-breaking rate, but other ice fields are suffering the same effects of global warming as well.
Arctic sea ice has melted to a record low extent; the smallest ever recorded since satellites began measuring it in 1979.
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...
