What Triggered Earth's Last Big Freeze
2012-11-06 09:53:08

April Flowers for redOrbit.com - Your Universe Online 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. This debate concerning the melt, which ushered in the last major cold episode about 12,900 years ago, has been raging for about 30 years. A research team from the University of...

Sea Levels Rising Fast
2012-11-02 08:28:50

April Flowers for redOrbit.com - Your Universe Online 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. The most recent IPCC report released in 2007 projected a global sea level rise between 0.2 and 0.5 meters by 2100, but current sea level measurements meet or exceed the high end of that range. This suggests a rise of one meter or more by the end of the century....

Ice Caps Grow and Shrink
2012-10-24 20:26:45

Brett Smith for redOrbit.com — Your Universe Online 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. However, a new study from NASA scientists has shown that this melt off around the Arctic is accompanied by the record expansion of sea ice around Antarctica, when the Southern Hemisphere is experiencing its colder temperatures of the year....

Understanding Antarctic Ice Loss
2012-10-22 19:44:40

Alan McStravick for redOrbit.com — Your Universe Online Amazing GRACE. Scientists and researchers have some interesting news out of Antarctica. The rate of global sea level change has been fairly well-established. The understanding for exactly why this is occurring got a new wrinkle this past week. Utilizing the Gravity Recovery and Climate Experiment (GRACE) satellite data, a team was able to more accurately calculate the ice sheet mass loss by mapping and removing the mass changes...

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. These are the findings of new research from the University of Gothenburg, Sweden. In Sannäs Fjord, a silled fjord to the north of Grebbestad in Bohuslän, researchers from the University of Gothenburg have studied the marine environment in the inner archipelago and built a treatment plant for...

Polar Ice Sheet Melt Influenced By Underwater Landscape
2012-10-17 12:25:09

Brett Smith for redOrbit.com - Your Universe Online As average global temperatures rise, climatologists are scrambling to see how this development might affect polar ice sheet melt, which could potentially result in a dangerous rise in sea levels. In studying the polar ice sheets 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 report...

Atlantic Heat Pump Was Once Faster
2012-10-16 13:39:01

April Flowers for redOrbit.com - Your Universe Online A new study from an international team of scientists led by environmental physicists at Heidleberg University in Germany suggests that the circulation of the Atlantic Ocean was faster during the last Ice Age than today. It has long been assumed that heat transport in the Atlantic Ocean during the last Ice Age was weaker, but according to the new data, it appears that it was actually stronger than it currently is. The team used...

Scientists and flight crew members with Operation IceBridge, NASA's airborne mission to study Earth's changing polar ice, are beginning another campaign over Antarctica. Now in its fourth year, IceBridge's return to the Antarctic comes almost a year after the discovery of a large rift in the continent's Pine Island Glacier. The first science flight of the campaign began Friday at 8 a.m. EDT when NASA's DC-8 research aircraft left Punta Arenas, Chile, for an 11-hour flight that will take it...

Glaciers Cracking In Presence Of Carbon Dioxide
2012-10-11 19:48:46

Alan McStravick for redOrbit.com — Your Universe Online Our glaciers and ice caps are experiencing a little chemistry-based “good cop, bad cop” and it looks like the bad cop is going to make them crack under pressure. There is little doubt in the scientific community about the excessive presence at startling levels of carbon dioxide (CO2) in our atmosphere and the effect it is having on our increasing global temperatures and our melting ice caps and glaciers....

Columbia Plateau
2013-04-19 16:35:47

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....

Arctic Ocean
2013-04-18 22:31:23

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
2009-07-06 17:15:30

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
