A new University of California, Davis, study by a top ecological forecaster says it is harder than experts thought to predict when sudden shifts in Earth's natural systems will occur -- a worrisome finding for scientists trying to identify the tipping points that could push climate change into an irreparable global disaster. "Many scientists are looking for the warning signs that herald sudden changes in natural systems, in hopes of forestalling those changes, or improving our preparations...

There is increased evidence that the Arctic could face seasonally ice-free conditions and much warmer temperatures in the future. Scientists documented evidence that the Arctic Ocean and Nordic Seas were too warm to support summer sea ice during the mid-Pliocene warm period (3.3 to 3 million years ago). This period is characterized by warm temperatures similar to those projected for the end of this century, and is used as an analog to understand future conditions. The U.S. Geological Survey...

The northern coastline of Alaska midway between Point Barrow and Prudhoe Bay is eroding by up to one-third the length of a football field annually because of a "triple whammy" of declining sea ice, warming seawater and increased wave activity, according to new study led by the University of Colorado at Boulder. The conditions have led to the steady retreat of 30 to 45 feet a year of the 12-foot-high bluffs -- frozen blocks of silt and peat containing 50 to 80 percent ice -- which are toppled...

A U.S. government agency predicted the melting of the polar ice cap in the year 2030. However, climate guru Al Gore said at the U.N. climate conference on Monday that new computer modeling indicates this could happen as soon as 2014. One U.S. government scientist on Monday said the new prediction was too severe, but other researchers have previously projected a quicker end than 2030 to the Arctic summer ice cap. Former U.S. Vice President Gore said, "It is hard to capture the astonishment...

High-resolution computer simulations performed by scientists at the National Oceanography Centre, Southampton (NOCS) are helping to understand the inflow of North Atlantic water to the Arctic Ocean and how this influences ocean climate. The summer of 2007 saw a record retreat in Arctic sea ice, and in general Arctic climate has become steadily warmer since the early 1990s. This has changed both sea ice drift and upper ocean circulation. The warm North Atlantic water intrudes into the central...

The East Antarctic ice sheet, once unaltered by global warming, has swiftly melted since 2006 and could increase sea levels, says a new study. Available in a recent issue of Nature Geoscience, the same research indicates that the West Antarctic ice sheet is also melting rapidly. Scientists are concerned that higher global temperatures could cause a quick collapse of West Antarctica, which has enough frozen water to raise the global ocean watermark by 16 feet. In 2007 the UN Intergovernmental...

Large blooms of tiny marine plants flourish in Antarctic waters left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula. This remarkable colonization is having a beneficial impact on climate change. As the blooms die back phytoplankton sinks to the...

International scientists, researchers and decision makers met at the "ËœSpace and the Arctic workshop' to identify the needs and challenges of working and living in the rapidly changing Arctic and to explore how space-based services can help to meet those needs. The workshop, held from 20 to 21 October in Stockholm, Sweden, was organized by the Swedish National Space Board and the Swedish Meteorological and Hydrological Institute together with ESA, EUMETSAT and the EC. The warmer...

Polar shipping routes have finally been unblocked, thanks to the virtual disappearance of the multiyear ice spanning the Arctic Ocean, according to an Arctic expert. For centuries, enormous sheets of multiyear ice reaching up to 260 feet thick have impeded the way of ships looking for a short cut through the fabled Northwest Passage from the Atlantic to the Pacific. However, Canada's Research Chair in Arctic System Science at the University of Manitoba, David Barber, noted that the ice is...

A team of researchers report that the Arctic ice cap could be non-existent during the summer months 20 to 30 years from now. Pen Hadow led the Catlin Arctic Survey team that explored the Arctic ice cap for 73 days. The team took more than 6,000 measurements during March and May in order to reach their conclusions on the condition of the Arctic ice cap. They traveled 290 miles, beginning in northern Canada, documenting ice thickness, density and depth. Based on their observations, the team...

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...
