A new NASA/British Antarctic Survey study examines why Antarctic sea ice cover has increased under the effects of climate change over the past two decades.
Since 1900 the global sea level has risen by approximately 20 cm. Melting glaciers are one of the causes – along with warming and thereby expanding sea water, melting Greenland and Antarctic ice sheets, and changing terrestrial water storage in dammed lakes and groundwater reservoirs.
While global warming has caused extensive melting of sea ice in the Arctic region in recent years, the opposite phenomenon has been occurring in Antarctica, and now experts believe they've discovered the reason why.
Climate scientists have long debated whether floodwaters from melting of the Laurentide Ice Sheet flowed northwest into the Arctic first, or east via the Gulf of St. Lawrence to weaken ocean thermohaline circulation and have a frigid effect on global climate.
Global warming is causing sea levels to rise faster than previously expected and geologist Bill Hay from the University of Colorado Boulder has a theory to explain why.
Over the past few years, researchers have consistently shown an overall decrease in the size of the Arctic ice cap—particularly during the summer months when the most melting occurs.
Utilizing satellite data, a team was able to more accurately calculate the ice sheet mass loss by mapping and removing the mass changes caused by the flow of rock beneath the Earth’s surface.
The number of leisure boats along the Swedish West Coast has risen dramatically over the last 20 years, resulting in a risk that the inner archipelago might be destroyed.
In a study on polar ice sheet melt around Antarctica, a group of British researchers has found that the shape of water channels beneath the ice can have a strong effect on ice behavior, temporarily hiding indications of its retreat.
A new study from an international team of scientists suggests that the circulation of the Atlantic Ocean – known as the Atlantic heat pump – was faster during the last Ice Age than today.
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...
