(Reuters) – While a vast containment operation dumps gallons of chemical dispersant and lays miles of plastic boom to attack a massive spreading oil slick, some U.S. Gulf Coast residents are turning to more unlikely remedies — hair and pantyhose. Shoreline communities threatened by the oil spewing from a ruptured Gulf of Mexico undersea well…

The US EPA announced that Canada and Mexico have joined the United States in proposing to expand the scope of the Montreal Protocol on Substances that Deplete the Ozone Layer to fight climate change. The proposal would phase down hydrofluorocarbons (HFCs), which are a significant and rapidly growing contributor to climate change. The U.S. Environmental…

There is a body of evidence linking general environmental exposures to cancer. A report was released today by the President’s Cancer Panel which finds that the true burden of environmentally induced cancer is underestimated. The Panel’s report, “Reducing Environmental Cancer Risk: What We Can Do Now,” concludes that while environmental exposure is not a new…

Three British scientists shocked the world when they revealed on May 16th, 1985 — 25 years ago — that aerosol chemicals, among other factors, had torn a hole in the ozone layer over the South Pole. The ozone layer, which protects life on Earth from damaging solar radiation, became an overnight sensation. And the hole…

The world can be a thoroughly depressing place. It seems like bad news is all we ever get, like oil spills destroying wildlife, killer hurricanes, economic collapse, and terrorists with bombs in their underwear. However, bad news is not always so bad. It motivates us to act, to learn from our mistakes, and eventually become…

The entire North Atlantic warmed up during the 1920s and 1930s. More fish appeared not only in the Barents Sea but also off Iceland and Greenland. This warm period reached its peak at the end of the thirties and lasted until roughly 1960, when the waters began turning colder again — and fisheries resources declined…

U.S. regulators exempted BP Plc from a detailed environmental review of the exploration project that ultimately resulted in the deadly Gulf of Mexico explosion and subsequent oil spill, documents show. The Minerals Management Service granted BP’s project a “categorical exclusion” from full environmental analysis normally required under the National Environmental Policy Act, according to documents…

Here we are in global warming but there are still places that can be outright cold. Antarctica, of course, comes to mind as well as Siberia. The lowest recorded air temperature on Earth was a measurement of −89.2C (-128.6 F) made at Vostok station, Antarctica, at 0245 UT on 21 July 1983. What could have…

With all the talk and shtick over “green” products, it’s easy to forgot that Tom’s of Maine has long been a leader in natural consumer products and sustainable business practices. Started in 1970 with a $5000 loan, the company’s products now take shelf space at 40,000 retail outlets, including Trader Joe’s and Whole Foods. From…

Oil spill workers raced against time in the Gulf of Mexico, hoping to seize on at least one more day of calm in their fight to contain a huge and growing slick before winds turn against them. Cleanup crews along the U.S. shore have had a few days’ reprieve as the slow-moving slick, from oil…
