re: the environment, check these startling stats out...
The climb in carbon dioxide content showed up in readings from the US government's National Oceanic and Atmospheric Administration, taken at the summit of Mauna Loa, Hawaii. The measurements have been taken regularly since 1958 in the 11,400ft peak's pristine conditions, 2,000 miles from the nearest landmass and protected by unusual climatic conditions from the pollution of Hawaii, two miles below.
Through most of the past half-century, levels of the gas rose by an average of 1.3 parts per million a year; in the late 1990s, this figure rose to 1.6 ppm, and again to 2ppm in 2002 and 2003. But unpublished figures for the first 10 months of this year show a rise of 2.2ppm.
Scientists believe this may be the first evidence that climate change is starting to produce itself, as rising temperatures so alter natural systems that the Earth itself releases more gas, driving the thermometer ever higher.
