As human beings continue their destructive rampage around the planet, they find themselves facing accelerating dilemmas on every continent. No one can deny quickening traumas facing humanity in the 21st century. Humans spew billions of tons of toxic air into the atmosphere while they plasticize the oceans, cut down the forests and tamper with nature's environmental balancing systems.
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.
