Gulf oil disaster fuels fears in Arctic
Oil gushing from a blowout in the Gulf of Mexico is stoking Canadian efforts to stop the federal government exploring for oil and natural gas in pristine Arctic seas that are supposed to become a marine park.
Ice streams: Charting the history of the ice caps
During ice ages, ice sheets move over fast-flowing ice streams that leave distinct geological signatures on the ocean floor. The relationship between ice streams and climate change forms the basis of a new study.
Moss 77 asks What do we need to know to act on climate change?
Richard Moss, Carleton class of 77, is a major climate change researcher and scientist who directed the US governments climate research program from 2000 to 2006, spanning the Clinton and Bush administrations. he main focus of his presentation was the role of paradigm shifts that resulted in scientific revolutions, which was prominently featured in understanding climate change.
The Message from the Glaciers
Many of the ancient civilizations of the world arose around Asias ten great rivers, which all find their source in the majestic arc of mountains that begins in Inner Asia and wraps itself around the Tibetan plateau to become the Himalayas before ending in southwest China. These mountains encompass the largest nonpolar ice mass in the world and since time immemorial have held water in frozen ...
Antarctic Micrometeorites Provide Clues to Solar System Formation
Researchers sifting through the pristine, cold snow in Antarctica have found micrometeorites that contain a bit of a surprise. The two micrometeorites, known as particles 19 and 119, contain extremely large amounts of carbon as well as excesses of deuterium. While this high organic content usually comes from distant interstellar space [...]
Currents Influence Fish Stocks: More Cod in the Barents Sea
The entire North Atlantic warmed up during the 1920s and 1930s. More fish appeared not only in the Barents Sea but also off Iceland and Greenland. This warm period reached its peak at the end of the thirties and lasted until roughly 1960, when the waters began turning colder again -- and fisheries resources declined once more. In recent years, the North Atlantic has shown signs of a new period ...
More glints of sunlight from liquid lakes on Saturns moon Titan
Astronomers have confirmed sunlight glinting from liquid lakes on the surface of Saturn's moon.
New atlas underlines significant role of northern soils in climate change
European researchers have launched a soil atlas of the world's northernmost regions, where more than half the carbon present in Earth's soils is stored. Although there has been much focus on the melting of arctic ice as one of the indicators for climate change, 1700 billion tons of organic carbon are kept in the soils of the northern permafrost region and their thawing could lead to substantial ...
Sunlight reflection confirms presence of liquid on Saturn's moon Titan
NASA's Cassini Spacecraft has captured a glint of light reflecting from the surface of Saturn's moon Titan, which confirms the presence of a lake filled with liquid.
Climate change hitting home
It also could mean disrupted food supplies from less citrus from Florida and California, to droughts in the wheat belt, and the gradual invasion of southern species, insects and diseases.
