Waste CO2 Could be Source of Renewable Power

Waste CO2 Could be Source of Renewable Power

They could, they argue, pump the carbon dioxide through water or other liquids and produce a flow of electrons and therefore more electricity. Power-generating stations release 12 billion tons of carbon dioxide every year as they burn coal, oil or natural gas; home and commercial heating plants release another 11 billion tons. This would be enough… Read More

Cruise to Greenland Will Weigh Arctic Drilling Risks

Cruise to Greenland Will Weigh Arctic Drilling Risks

An ambitious attempt to learn more about what is happening to the Arctic sea ice is getting under way with the start of a two-week research cruise to the waters off the north-eastern coast of Greenland. The scientists will measure a range of parameters of the sea ice, icebergs and how they interact with their ship, the Swedish polar icebreaker … Read More

Krill Face Greater Risks in Warming Antarctic Waters

Krill Face Greater Risks in Warming Antarctic Waters

They may not look very appetizing, but they are what sustains much of the marine life in the southern ocean. Antarctic krill, usually less than 2.36 inches long, are the primary food source for many species of whale, seal, penguin and fish. But there’s a problem: the waters round Antarctica are warming, and it looks as if they will probably contin… Read More

The Calm Before the Storm? Quiet August for Hurricanes

The Calm Before the Storm? Quiet August for Hurricanes

The mid-September peak of the Atlantic hurricane season is rapidly approaching, but so far, a season that was forecast to be unusually active has been a bit of a snoozefest. Not a single hurricane has formed yet, as the five named storms that did spin up were unable to strengthen significantly. Weather forecasters warn, however, that the season wil… Read More

Arctic Warming May Not Be Altering Jet Stream: Study

Arctic Warming May Not Be Altering Jet Stream: Study

A new study calls into question the widely-publicized hypothesis that rapid warming of the Arctic climate, including the precipitous loss of summer sea ice cover, is altering weather patterns throughout the Northern Hemisphere. Specifically, the study, which will be published in a forthcoming issue of Geophysical Research Letters, challenges the fi… Read More

Australia’s Flooding Rains Briefly Slowed Sea Level Rise

Australia’s Flooding Rains Briefly Slowed Sea Level Rise

Scientists may have zeroed in on the cause of a mysterious 18-month drop in global average sea level that occurred between 2010 and 2011, pointing to events that occurred on the world’s smallest continent: Australia. New research shows that during those two years, flooding rains in Australia, which resulted from a rare combination of factors, took … Read More

Wildfire Alert Heightened as Blazes Char Western U.S.

Wildfire Alert Heightened as Blazes Char Western U.S.

With 51 large wildfires currently burning across the U.S., the nation’s firefighters have been placed on a war footing — known as “National Preparedness Level 5.” This is the first time this step has been taken since 2008, according to Wildfire Today, and it reflects the combination of high fire activity, the large amounts of firefighting resources… Read More
