Researchers Decipher Climate Paradox From The Miocene

AWI Scientists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have deciphered a supposed climate paradox from the Miocene era by means of complex model simulations. When the Antarctic ice sheet grew to...

National Snow and Ice Data Center Will next year’s summer Arctic ice extent be high or low? Can ship captains plan on navigating the famed Northwest Passage — a direct shipping route from Europe to Asia across the Arctic Ocean — to save on time and fuel? A new study says year-to-year forecasts of the Arctic’s summer ice extent are not yet reliable. Scientists at the National Snow and Ice Data Center (NSIDC), University College London, University of New Hampshire and University...

Warm Rivers Play A Role In Arctic Sea Ice Melt
2014-03-06 06:32:21

Brett Smith for redOrbit.com - Your Universe Online According to a new study from NASA researchers, warm river waters draining into the Arctic Ocean are adding to the melting of sea ice in the Arctic Ocean each summer. Published in the journal Geophysical Research Letters, researchers reported on an abrupt inflow of warm river water into the Arctic Ocean that swiftly warmed the top layers in the sea, fueling the melting of summer ice. “River discharge is a key factor contributing...

Arctic Sea Ice Trends

April Flowers for redOrbit.com - Your Universe Online According to new research from the University College London, the melt season across the Arctic is getting longer by five days every ten years. Julienne Stroeve, Professor of Polar Observation and Modeling at UCL Earth Sciences, led the team in analyzing satellite data. The analysis, published in Geophysical Research Letters, revealed that the Arctic Ocean is absorbing even more of the sun’s energy in summer, leading to an even...

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...

April Flowers for redOrbit.com - Your Universe Online The Ross Sea is a major, biologically productive ecosystem in the Antarctic, which "clearly will be extensively modified by future climate change" in the coming decades as longer periods of ice-free open water are created by rising temperatures and changing wind patterns. According to a new paper funded by the National Science Foundation (NSF), these ice-free periods affect the life cycles of both predators and prey. The research...

CERES Satellite Data Paint A Grim Picture Of Arctic Surface Darkening
2014-02-19 07:03:42

Lawrence LeBlond for redOrbit.com - Your Universe Online Earth’s reflectivity (albedo) is on a much faster decline than previously estimated due to the retreat of sea ice in the Arctic Ocean. A key instrument incorporated on several NASA satellites has revealed significant data on this profoundly concerning issue. A team of researchers from University of California, San Diego’s Scripps Institution of Oceanography used data from the Clouds and Earth’s Radiant Energy System (CERES),...

El Nino Could Be Light at End of Tunnel Las Vegas, Nev. (PRWEB) February 04, 2014 Winter is only half over, and the extreme cold has already broken thousands of records in the Central and Eastern U.S. Meanwhile, the Western U.S. is breaking drought records. Both are caused by a dynamic jet stream shifting the cold far north in the West and far south in the East says Evelyn Browning-Garriss, noted climatologist and author, who predicted this extremely cold winter and California drought in...

Winter Ice Is On The Decline Across Alaskan Lakes
2014-02-03 10:22:48

Brett Smith for redOrbit.com - Your Universe Online According to a new study from the European Space Agency, ice in northern Alaska’s lakes during winter months is on the decline. Twenty years of satellite radar images in the study, which was published in The Cryosphere, show how shifts in our climate are affecting high-latitude regions. [ Watch the video: Monitoring Lake Ice ] Alterations in air temperature and winter precipitation over the last 50 years have affected the timing,...

Increased Mercury Levels In Arctic Ice Found Pushing Into Sea Water
2014-01-16 10:15:32

Gerard LeBlond for redorbit.com - Your Universe Online Researchers Dr. Chris Moore and Dr. Daniel Obrist, from Nevada's Desert Research Institute, have recently discovered an increased level of mercury in Arctic sea ice. The study, published in the journal Nature, also found that the element is contaminating sea water below. The researchers claim that the air above large cracks found in the ice of the Arctic is mixing vigorously pushing mercury down to the exposed seawater. This process...

A climate change science-tourism expedition got trapped when they set out to prove global warming is causing Antarctica's sea ice to melt, despite data showing the Antarctic 2013 year-average sea ice area is the highest ever recorded during the satellite era, which began in 1979. Friends of Science point out on their Polar Region Sea Ice web-page that Antarctic sea ice data shows it is 1.5 million sq. km larger than 30 year average and that there has been no global warming in 16...

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...
