Freshwater under the ocean

Vast reserves of freshwater have been discovered beneath the seabed of continental shelves off Australia, China, North America, and South Africa—a potentially valuable resource for coastal cities needing to alleviate water shortages or combat drought. The finding comes from a new analysis of seafloor water studies conducted for oil and gas exploration purposes. The total volume of these untapped reserves […]

More certainty on global warming

An influential panel of climate scientists has expressed higher confidence than ever that human activity is the main cause of the rise in global temperatures since the 1950s, Reuters.com reports. A leaked draft of an upcoming report of the United Nations’ Intergovernmental Panel on Climate Change, based on a broad analysis of published scientific studies, concludes with 95 percent certainty […]

Antarctica’s warming shock

Western Antarctica is heating up faster than almost any other region on earth, increasing the risk that a huge ice sheet there could collapse and cause a drastic rise in sea levels. That’s the alarming conclusion of climate researchers who used data from a remote weather station combined with other temperature readings on the continent to show that West Antarctica […]

How Sea Ice Forms

Sea ice is formed from ocean water that freezes. Because the oceans consist of saltwater, this occurs at about minus 1.8 degrees Celsius (28.8 degrees Fahrenheit). Most Antarctic sea ice occurs annually, meaning it forms in the winter and melts during the summer. Sea ice regulates exchanges of heat, moisture and salinity in the polar oceans. It insulates the relatively warm […]

The Arctic’s ozone hole

The ozone layer over the Arctic Circle developed a giant hole this winter, scientists say. Over the North Pole, 40 percent of the ozone layer has disappeared—a record seasonal loss. Ozone high in the atmosphere shields the Earth from harmful UV rays, and it fluctuates seasonally; usually about 25 percent of the Arctic’s ozone layer fades every winter. In the […]

Ice Levels In Antarctica Increasing

Cynic contentions that Antarctica is picking up ice every now and again rely on a slip of oversight, to be specific overlooking the contrast between area ice and ocean ice. In glaciology and especially regarding Antarctic ice, not everything is made equivalent. Give us a chance to consider the accompanying contrasts. Antarctic area ice is the ice which has aggregated […]
