Moths And The Masking Of Climate Change

Brett Smith for redOrbit.com - Your Universe Online A new climate change study conducted on sub-Arctic moths living in Finland has revealed mixed results: moths seem to be thriving despite a warmer, wetter climate – while an as-yet-unknown...

Moss Still Lives After 1500 Years Buried In Antarctic Ice
2014-03-17 14:57:18

Brett Smith for redOrbit.com - Your Universe Online British researchers who typically study polar moss samples because they provide indications of past climate conditions have found that Antarctic moss can survive trapped under ice for over 1,500 years. While some plant material has been brought back to life after 20 years of being frozen, only microbes have been shown to be capable of thousand-year feats of revival; that is until now. "These mosses were basically in a very long-term...

WASHINGTON, March 12, 2014 /PRNewswire-USNewswire/ -- Researchers aboard NASA's P-3 research aircraft left the agency's Wallops Flight Facility in Wallops Island, Va., March 10 for Greenland to begin a new season of collecting data on Arctic land and sea ice. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The mission, known as Operation IceBridge, is to gather data on changes to polar ice and maintain continuity of measurements between NASA's Ice, Cloud and Land Elevation...

Ice Age Flora And Fauna May Have Relied On Volcanic Heat To Thrive
2014-03-12 05:43:40

redOrbit Staff & Wire Reports - Your Universe Online Several types of plants and animals were able to survive ice ages of the past thanks to the heat and steam produced by volcanoes, according to research appearing in a recent edition of the Proceedings of the National Academy of Sciences (PNAS). Dr. Ceridwen Fraser of the Australian National University, Dr. Aleks Terauds from the Australian Antarctic Division and their colleagues said that their research has helped solve a...

Antarctic ice shelf
2014-03-03 05:04:27

McGill University In the mid-1970s, the first available satellite images of Antarctica during the polar winter revealed a huge ice-free region within the ice pack of the Weddell Sea. This ice-free region, or polynya, stayed open for three full winters before it closed. Subsequent research showed that the opening was maintained as relatively warm waters churned upward from kilometers below the ocean's surface and released heat from the ocean's deepest reaches. But the polynya -- which...

Climate Change Sentinels In The Arctic
2014-02-15 04:47:25

Brett Smith for redOrbit.com - Your Universe Online Being particularly sensitive to carbon monoxide and methane, canaries were often used by miners as sentinels to determine if the toxic mine-related gases were building up to dangerous levels. Speaking this week at the annual meeting of the American Association for the Advancement of Science in Chicago, oceanographer Sue Moore said walruses, polar bears and seals can be looked at in much the same way, in that well-being of these Arctic...

Arctic Biome Under Extreme Threat From A Changing Climate
2014-02-14 10:55:40

Brett Smith for redOrbit.com - Your Universe Online The Arctic as we know it may not exist as climate change is threatening the polar biome’s unique biodiversity and landscape, according to a new report from a large international team of scientists. Conducted by the Conservation of Arctic Flora and Fauna (CAFF) under the Arctic Council, an international forum of Arctic nations, the new study found that climate change could shrink Arctic ecosystems, as advancing changes move north and...

Polar Bear Diets Change Climate Change
2014-01-23 13:03:52

Lee Rannals for redOrbit.com - Your Universe Online Polar bears are able to switch up their diet in order to help them survive the warming Arctic, according to a new study. Scientists at the American Museum of Natural History performed a three-part study that shows how polar bears switch up plant and animal food sources as they face the changing climate. Arctic sea ice is beginning to melt earlier and freezing later each year, so polar bears are having a limited amount of time to hunt...

Arctic Warmth Reveals Samples Of Ancient Moss
2014-01-21 14:51:23

Wiley When the temperature rises on Baffin Island, in the Canadian high Arctic, ancient Polytrichum mosses, trapped beneath the ice for thousands of years, are exposed. Using radiocarbon dating, new research in Geophysical Research Letters has calculated the age of relic moss samples that have been exposed by modern Arctic warming. Since the moss samples would have been destroyed by erosion had they been previously exposed, the authors suggest that the temperatures in the Arctic are...

[ Watch the Video: A Giant Is Lurking Beneath Antarctica's Ice ] Gerard LeBlond for redOrbit.com - Your Universe Online A team of scientists from Newcastle University, the University of Bristol’s Glaciology Centre, the British Antarctic Survey and the universities of Edinburgh, Exeter and York, have discovered a giant trench below the ice in Antarctica. The research team has spent the last three seasons in the West Antarctic region investigating and mapping the area. Recently, they...

Antarctic High Ridge Gets Distinction As Coldest Place On Earth

[ Watch the Video: Coldest Place On Earth Is The East Antarctic Plateau ] redOrbit Staff & Wire Reports - Your Universe Online If you think it’s cold where you live, consider this: NASA satellites have just discovered the chilliest place on Earth, where temperatures can plummet to minus 133.6 degrees Fahrenheit (minus 92 degrees Celsius). This “glad I don’t live there” location is a high ridge in Antarctica on the East Antarctic Plateau, where temperatures in several...

Roald Amundsen was a Norwegian explorer that was known for his expeditions into polar regions. He is best known for his discovery of the South Pole, being the first recognized explorer to reach the North Pole, and being the first explorer to travel along the Northwest Passage. He was born to Jens Amundsen and Hanna Sahlqvist in July of 1872. His family owned and managed a number of ships, but his mother did not want him to join the family trade, encouraging him to become a doctor. Amundsen...

Antarctica

Antarctica is the Earths southernmost continent; it contains the geographic South Pole. It’s situated in the Antarctic area of the Southern Hemisphere, almost completely south of the Antarctic Circle, and is bordered by the Southern Ocean. It’s the fifth-largest continent at 5.4 million sq miles. On average, it is the driest, coldest, and windiest continent as well as having the highest average elevation of all the continents. Considered a desert, the annual precipitation is only 8...

The Amundsen-Scott South Pole Station is a U.S. research facility based at the South Pole, in Antarctica. It is the southernmost continually inhabited place on the planet. Its name honors Roald Amundsen who reached the South Pole in December 1911, and Robert F. Scott who reached the South Pole in January 1912. The station was constructed in 1956 to support the International Geophysical Year in 1957. It has been continuously occupied since then. It currently lies within 330 feet of the...

Arctic Circle -- The Arctic (Land of the Midnight Sun) is the area around the earth's North Pole while antarctic is in South Pole. It includes parts of Russia, Alaska, Canada, Greenland, Lapland and Svalbard as well as the Arctic Ocean. The Arctic Circle is one of the five major circles of latitude that mark maps of the Earth. Everything north of this circle is known as the Arctic, and the zone just to the south of this circle is the Northern Temperate Zone. This is the parallel of...
