Additional federal studies are under way to see if any contamination reaches taps or ground water used for drinking, but the program under which they are conducted, the toxic substances hydrology program of the geological survey, is slated to be eliminated under budget cuts proposed by the Bush administration, government officials said... estrogens and similar compounds are increasingly the focus of research by the Environmental Protection Agency and many scientists because of hints that they alter sexual characteristics in fish and other aquatic species.

The survey of more than 100 waterways downstream from treatment plants and animal feedlots in 30 states found minute amounts of dozens of antibiotics, hormones, pain relievers, cough suppressants, disinfectants and other products. It is not known whether they are harmful to plants, animals or people. The findings were released yesterday on the Web site of the United States Geological Survey, which conducted the research, and in an online journal, Environmental Science and Technology.

You never know you're in a bubble until it pops.

When I wrote a long story about the retreat of sea ice, I made clear it could go the other way for a while, and that doesn't mean we don't know that a warmer world will have less sea ice. It just means there's a lot of variability and people can pay too much attention to the big swings in one direction or the other.

We're an amazingly adaptive and resilient species. Once we put our mind to global warming, I have no doubt we'll figure a way through here that won't lead to utter calamity.

There are still people who essentially live in intellectual silos and either read Mother Jones or watch Fox News, based on their worldview. And they pick information out that reinforces it rather than keeping an open mind.

Scientists are also unnerved by the summer's implications for the future...proof that human activities are propelling a slide toward climate calamity...humans may have tipped the balance...a particularly harsh jolt to polar bears.
