According to a paper in this week's issue of the journal Science, the vast majority of the world's glaciers are retreating as the planet gets warmer.  For the last 7,000 years, New Zealand's largest glaciers have moved out of step with glaciers in the Northern Hemisphere, showing strong regional variations in climate, the paper reported. "This research should provide much more accurate reconstructions of glacial advances worldwide, allowing us in turn to make climate models more...

An international team of researchers, including Antoni Rosell, ICREA researcher at the Institute of Environmental Science and Technology (ICTA) and professor of the Department of Geology, Universitat Autònoma de Barcelona, who participated as a member of the direction team, have created MARGO (Multiproxy Approach for the Reconstruction of the Glacial Ocean Surface), a new quantitative tool which reconstructs the sea surface temperature during the Last Glacial Maximum....

New research indicates that the ocean could rise in the next 100 years to a meter higher than the current sea level "“ which is three times higher than predictions from the UN's Intergovernmental Panel on Climate Change, IPCC. The groundbreaking new results from an international collaboration between researchers from the Niels Bohr Institute at the University of Copenhagen, England and Finland are published in the scientific journal Climate Dynamics.According to the UN's...

Intense glacial erosion has not only carved the surface of the highest coastal mountain range on earth, the spectacular St. Elias range in Alaska, but has elicited a structural response from deep within the mountain. This interpretation of structural response is based on real-world data now being reported, which supports decades of model simulations of mountain formation and evolution regarding the impact of climate on the distribution of deformation associated with plate tectonics. A team of...

Scientists reported Wednesday that in 10,000 years a massive, worldwide freeze could overcome the planet, more deadly than the Ice Age. British and Canadian researchers said greenhouse gases could prove beneficial in the future to battle a chill that could cover Canada and the United States, Europe and Russia in permanent ice. However, scientists contend the world should not stop fighting global warming, theoretically stoked by human emissions of heat-trapping gases from burning fossil...

New insights into natural changes in atmospheric methane concentrationsIce cores are essential for climate research, because they represent the only archive which allows direct measurements of atmospheric composition and greenhouse gas concentrations in the past. Using novel isotopic studies, scientists from the European Project for Ice Coring In Antarctica (EPICA) were now able to identify the most important processes responsible for changes in natural methane concentrations over the...

Using the latest satellite observations, NASA researchers and others report that the Arctic is still on "thin ice" when it comes to the condition of sea ice cover in the region. A colder-than-average winter in some regions of the Arctic this year has yielded an increase in the area of new sea ice, while the older sea ice that lasts for several years has continued to decline. On March 18 the scientists said they believe that the increased area of sea ice this winter is due to recent weather...

Each year, long-distance winds drop up to 900 million tons of dust from deserts and other parts of the land into the oceans. Scientists suspect this phenomenon connects to global climate - but exactly how, remains a question. Now a big piece of the puzzle has fallen into place, with a study showing that the amount of dust entering the equatorial Pacific peaks sharply during repeated ice ages, then declines when climate warms. The researchers say it cements the theory that atmospheric...

Researchers also find tantalizing evidence that ancient tropical eruptions of volcanoes triggered Little Ice Age A new University of Colorado at Boulder study has shown that ice caps on the northern plateau of Baffin Island in the Canadian Arctic have shrunk by more than 50 percent in the last half century as a result of warming, and are expected to disappear by the middle of the century. Radiocarbon dating of dead plant material emerging from beneath the receding ice margins show the Baffin...

Wobbles on Mars cause ice ages that are much more dramatic than those on Earth, says astronomer Norbert Schörghofer of the University of Hawaii. Thanks to our large, stabilizing Moon, Earth's rotation axis is always tilted by about 23 degrees. The tilt of Mars, however, can wobble by as much as10 degrees from its current 25 degrees. Wobbles cause big changes in the amount of sunlight reaching different parts of Mars, so vast amounts of ice shift between the poles and the rest of the...

Arctic Ocean

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...

The water cycle (or hydrologic cycle) describes the continuous movement of water above, below, and on the planet. Since the water cycle is in fact a "cycle", there is no beginning or end. Water exists in three states: liquid, vapor, and ice. Although the balance of water on our planet is fairly constant, individual water molecules may come and go. The water cycle is driven by the sun. The sun heats the oceans and allows water to evaporate into the air. The sun also heats snow and ice which...
