Mercury Persists in Fish in Many Parts of US
August 20, 2009 06:39 AM - Roger Greenway, ENN

The U.S. Geological Survey released a study that showed mercury contamination in every fish sampled in 291 streams across the country. The work was part of the National Water-Quality Assessment Program (NAWQA) which provides an understanding of water-quality conditions such as whether conditions are getting better or worse over time and how natural features and human activities affect those conditions. Regional and national assessments are possible because of a consistent study design and uniform methods of data collection and analysis.

Not from My Back Yard? Homes Pollute

They say there's no place like home. But scientists are reporting some unsettling news about homes in the residential areas of California. The typical house there — and probably elsewhere in the country — is an alarming and probably underestimated source of water pollution, according to a new study reported today at the 238th National Meeting of the American Chemical Society.

No Matter How Well You Model it, Humans are to Blame

New research appearing in the online issue of the Proceedings of the U.S. National Academy of Sciences, Lawrence Livermore National Laboratory scientists and a group of international researchers found that model quality does not affect the ability to identify human effects on atmospheric water vapor.

August 15, 2009 07:47 AM - R. Greenway, ENN

The Earth's oceans were the warmest ever this July, according to a study released by the National Oceanic and Atmospheric Administration yesterday. The planet's ocean surface temperature was the warmest on record for July, breaking the previous high mark established in 1998 according to an analysis by NOAA's National Climatic Data Center in Asheville, N.C. The combined average global land and ocean surface temperature for July 2009 ranked fifth-warmest since world-wide records began in 1880.

Wobbling Earth Triggers Climate Change
August 14, 2009 02:26 PM - Annabel McGilvray, ABC Science Online

Regular wobbles in the Earth's tilt were responsible for the global warming episodes that interspersed prehistoric ice ages, according to new evidence. The finding is the result of research led by Russell Drysdale of the University of Newcastle that has been able to accurately date the end of the penultimate ice age for the first time.

Seining Salmon in the Seine?

Salmon are returning to the Seine after an absence of almost a century as water in the river that runs through Paris has become cleaner in recent years, French scientists said. Once numerous in the river, Atlantic salmon disappeared from the Seine in the early 20th century, partly due to pollution from Paris sewers. But scientists celebrated an improvement in water quality in the Seine that has tempted the protected species back to Paris.

Airlines Will Be First U.S. Industry to Confront Cap and Trade
August 13, 2009 09:22 AM - Paul Voosen, Greenwire New York Times

Sometime this month, the European Union will release a list of airlines it will regulate under its existing cap-and-trade system for carbon dioxide. And several airlines on that list will have a decidedly New World feel: Delta, United and American.

Acid In The Oceans: A Growing Threat To Sea Life
August 13, 2009 09:12 AM - Richard Harris, NPR

When we burn fossil fuels, we are not just putting carbon dioxide into the atmosphere. A lot of it goes into the sea. There, carbon dioxide turns into carbonic acid. And that turns ocean water corrosive, particularly to shellfish and corals.
