April 6, 2009 05:36 AM - Envriopolitics Blog

Interior Secretary Ken Salazar is coming to Atlantic City TODAY to discuss the future of offshore energy. He says he wants to know what you think, too. It will be the Obama Administration official's first stop on a tour of public meetings to be followed by sessions in New Orleans, Anchorage and San Francisco. Salazar will present information from a U.S. Geological Survey-Minerals Management Service Report and will solicit public comment. ENN will be reporting on this event later today.

10-Year Study Uncovers Toxic Aspects of DBPs
April 6, 2009 05:25 AM - Water & Wastewater News

University of Illinois geneticist Michael Plewa said that disinfection byproducts (DBPs) in water are the unintended consequence of water purification. "The process of disinfecting water with chlorine and chloramines and other types of disinfectants generates a class of compounds in the water that are called disinfection byproducts. The disinfectant reacts with the organic material in the water and generates hundreds of different compounds. Some of these are toxic, some can cause birth defects, some are genotoxic, which damage DNA, and some we know are also carcinogenic."

We Drive Nissan's Electric Car, and It's Sweet

The prototype of Nissan's forthcoming electric car may look like a breadbox, but the technology beneath that boxy body could propel the Japanese automaker to the front of the EV pack when the car hits the road next year.

Ice bridge holding Antarctic ice shelf cracks up

An ice bridge which had apparently held a vast Antarctic ice shelf in place during recorded history shattered on Saturday and could herald a wider collapse linked to global warming, a leading scientist said.

Medieval warming 1000 yrs ago was a result of natural climate mechanism

In a new research, scientists have unraveled the natural climate mechanism that caused unusually warm weather in medieval times in Europe 1000 years back.

Climate clock is ticking
April 5, 2009 07:00 AM - WILLIAM MARSDEN, The Montreal Gazette

In the summer of 2007, a large portion of Arctic Sea ice - about 40 per cent - simply vanished. That wasn't supposed to happen. At least not yet. As recent as 2004, scientists had predicted it would take another 50 to 100 years for that much ice to melt. Yet here it was happening today.

First Accurate Test For Arsenic In Soil Developed
April 3, 2009 10:10 AM - Science Daily

If you have a cat or dog who likes to hide under the deck or children who play on equipment made with pressure-treated wood, you’ll be glad to hear that analytical chemist Julian Tyson and colleagues at the University of Massachusetts Amherst recently developed the first-ever accurate test for arsenic compounds in soil, promising a significantly improved environmental and health impact assessment. The method holds some promise for detecting naturally occurring high arsenic levels in Asian rice, as well.

Ice-free Arctic Ocean Possible In 30 Years, Not 90 As Previously Estimated
April 3, 2009 05:25 AM - ScienceDaily

A nearly ice-free Arctic Ocean in the summer may happen three times sooner than scientists have estimated. New research says the Arctic might lose most of its ice cover in summer in as few as 30 years instead of the end of the century.
