It has taken a quarter of a century, but US researchers say their work has finally enabled them to determine to what extent city air pollution impacts on average life expectancy.
Drinking Water Threatened: TVA Tries to Hide Information About Water Contamination from Massive Coal Spill
The Tennessee Valley Authority manipulated science methods to downplay water contamination caused by a massive coal ash disaster, according to independent technical experts and critics of the federally funded electrical company.
The TVA is the largest public provider of electricity in the nation, providing power to 670,000 homes and burning through some 14,000 tons of coal per day. On December 22 the authority made headlines when one of its retention ponds collapsed, letting loose an avalanche of coal ash -- the toxic residue left over when coal is burned. More than 5 million cubic yards of ashy mud pushed its way through a neighborhood and into Tennessee's Emory River, knocked houses off foundations and blanketed river water with plumes of gray scum that flowed downstream.
An ice bridge linking a shelf of ice the size of Jamaica to two islands in Antarctica has snapped.
Scientists say the collapse could mean the Wilkins Ice Shelf is on the brink of breaking away, and provides further evidence or rapid change in the region.
Arctic sea ice is melting so fast most of it could be gone in 30 years. A new analysis of changing conditions in the region, using complex computer models of weather and climate, says conditions that had been forecast by the end of the century could occur much sooner.
The United States Navy requests permissions from the United States Department of Commerce (NOAA), to kill thirty two species of marine mammals over five years in their Pacific Ocean Warfare testing program.
According to Navy Public Relations Officer Sheila Murray the United States Navy is already conducting warfare testing programs throughout the United States. During the last two years, it is alleged that the Navy has issued nearly identical environmental impact statements for Navy Warfare Training Range Complexes in the following areas: the Mariana Islands, the Hawaiian Islands, Jacksonville Florida, Cherry Point, North Carolina, the Gulf of Alaska and Southern California. It is unknown, at this time, how many marine mammals have been killed in these programs since their inception.
