Power sockets that sense when you leave a room and shut down. Portable hydrogen fuel cells. Pocket windmills that store electricity. Those were some of the little-noticed green power-savers tucked into a little corner of the otherwise monstrous Consumer Electronics Show floor in Las Vegas.
Scientists aboard the Ocean Watch, a 64-foot yacht on a year-long voyage circling the Americas, are testing the waters as they go. Instruments on the vessel have picked up evidence of ocean acidification, another result of the spewing of carbon dioxide from tailpipes and smokestacks, they say.
Much of CO2 pollution ends up in the atmosphere, but some is absorbed in the ocean, where it is converted into carbonic acid. The average pH of the word’s oceans is about 8.1 and the lower the reading, the greater the acidity.
Scientists are concerned that if pH levels keep falling ocean waters could eat away the shells of organisms large and small. That would put the web of ocean life at risk, not to mention be a potential disaster for land-loving seafood lovers
Ocean Watch has picked up readings of 7.88 in the Gulf of Alaska. Michael Reynolds, the scientist taking the measurements, said the preliminary data may show that the Gulf of Alaska is a primary “sink” for atmospheric carbon.
The good news is that readings have returned to normal as the voyage continues off the coast of South America.

LONDON - Yesterday's announcement by Senator Byron Dorgan (Democrat, North Dakota) that he would not seek a fourth term in November, coupled with today's expected announcement by Senator Chris Dodd (Democrat, Connecticut) that he won't seek a sixth term, will remove two veterans, once secure legislators from the Democratic caucus.
It highlights the mounting problems confronting congressional Democrats facing voters in November's midterms amid high unemployment, a relatively unpopular agenda led by the administration, and concerns about the party's capture by special interests.
It was a cold night with the wind chill reaching -18.4 degrees Celsius. By 5.00 a.m. I’d had enough of being cold and weather beaten by the Katabatic wind smashing the side of my tent and bouncing off my head so I decided to make my way to our base, the Sorensen Hut, for a warm cup of tea and read a couple of pages of my book.
Penguins’ chatter outside my tent woke me to Christmas Day in Antarctica, but instead of Santa’s sleigh there was just the usual run to ensure our human waste doesn’t permanently become part of this frozen wilderness.

Sweden complained that the recent Copenhagen climate change summit was a "disaster." British Prime Minister Gordon Brown described it as "at best flawed and at worst chaotic." Sudan's U.N. ambassador, Abdalmahmoud Abdalhaleem, dubbed the outcome confirmation of a "climate apartheid." For South Africa it was simply "not acceptable."
