POPSAccuracy of radiometric dating an earlier clip got me looking for resources on the internet to explain simply, yet completely, the underpinnings of radiometric dating. www.pbs.org/evolution provides a good starting point for many such references. there is a religious tract on the internet that makes many claims about the inaccuracy of radiometric dating methods and the infallibility of the bible as a historical record. the link in this clip addresses some of its primary claims.

POPSNew clues on "The Great Dying" The lessons of the Permian-Triassic massacre are "directly applicable to the present," said John Isbell, a geoscientist at the University of Wisconsin in Milwaukee. He said the world today is in danger of exceeding a CO2 "threshold" that could set off an environmental upheaval as great as the one 251 million years ago.

POPSEPA protecting Business Interests Again Two articles here, EPA saying no "significant" health risk and the university professor talking about his experiments in the lower article. My very first question to the EPA would be, "What do you define as significant?" Only 1 of 10 people dying?

POPSPersian Clouds - NLC's going south
Spaceweather says: "Noctilucent clouds (NLCs) are supposed to be a high-latitude phenomenon, most often seen in Canada, Russia and northern Europe. On July 19th the electric-blue clouds crept south, all the way to Iran: "I took this picture from Mt. Sabalan, a 15,784 ft extinct volcano in northwestern Iran," says Siamak Sabet. "It is the third highest peak in our extremely mountainous country." When noctilucent clouds first appeared in the late 19th century, they were confined to latitudes above 50o N. Mt Salaban is located at 38o N, far below the old threshold. Just last week, NLCs were sighted in Turkey at 40o N and in recent years they have appeared at least as far south in the United States as Colorado and Utah, also around 40o N. Why are NLCs spreading south? That is an unsolved mystery of these puzzling clouds. Some researchers believe it is a telltale sign of climate change, but this remains controversial. One thing is certain: Sky watchers at all latitudes should be ale

POPSThe 'Idle' Oil Field Fallacy or that there is not enough to justify the tremendous investment required to bring it to the surface – the company cuts its losses by moving on to more promising leases. Yet it continues to pay rent on the lease, atop a leasing bonus fee. Our companies have made tremendous strides in developing cutting-edge exploration technology. But they are not magicians. They cannot produce oil or natural gas where it does not exist. In reality, a lease is simply a block on a map, with no guarantee that it contains any resources. If all of them did, one could simply pay for the lease, haul in equipment and start pumping oil. But that only happens in fiction. Today's short-term need was yesterday's long-term opportunity. If Congress had acted on that opportunity years ago, America would not be in the energy bind it finds itself in today. Working with industry, Congress now has the opportunity to help secure America's energy future. It should not miss the chance again.

POPSNatural 'Invisible' Gold Found In Nanoparticles “On investigation of these crystals, there appeared to be a dark band across them. However, high magnification imaging showed the band was in fact, a mass of gold nanoparticles and nanoplates. These are identical to those being manufactured in laboratories around the world for their unique properties.”
