Biodiversity extinction crisis looms says renowned biologist
(03/12/2007) While there is considerable debate over the scale at which biodiversity extinction is occurring, there is little doubt we are presently in an age where species loss is well above the established biological norm. Extinction has certainly occurred in the past, and in fact, it is the fate of all species, but today the rate appears to be at least 100 times the background rate of one species per million per year and may be headed towards a magnitude thousands of times greater. Few people know more about extinction than Dr. Peter Raven, director of the Missouri Botanical Garden. He is the author of hundreds of scientific papers and books, and has an encyclopedic list of achievements and accolades from a lifetime of biological research. These make him one of the world's preeminent biodiversity experts. He is also extremely worried about the present biodiversity crisis, one that has been termed the sixth great extinction.

Global warming is causing stronger Atlantic hurricanes finds new study
(03/01/2007) Global warming is fueling stronger hurricanes according to a new Geophysical Research Letters study that revises that database of historic hurricanes. Previously the hurricane database was considered inconsistent for measuring the record of tropical storms since there have been significant improvements in the technology to measure storms since recording-keeping began. Before the development of weather satellites, scientists relied on ship reports and sailor logs to record storms. The advent of weather satellites in the 1960s improved monitoring, but records from newer technology have never been squared with older data. The new study normalizes the hurricane record since 1983.

Balloon technology could cut cost of solar energy 90% by 2010
(02/21/2007) With high energy prices and mounting concerns over human-induced climate change, there is intense interest in renewable energy, especially solar, which produces no pollution and is readily available in the form of sunlight. In recent years, however, the solar energy market has been hampered by supply shortages of refined silicon, the critical resource needed for solar cell fabrication. Further, because solar installations traditionally require a large surface area to capture as much sunlight as possible, solar arrays often take up real estate, occupying land used agricultural production and other purposes. Without government subsidies, solar is not presently viable in many areas.

U.S. forests suffer from beauty products packaging
(02/14/2007) Every year millions of acres of forests in the southern United States are cut to fuel the pulp and paper industry. Nearly 25 percent of this demand comes from paper packaging, which usually ends up in landfills after a brief life as a disposable product. To support this industry, millions of acres of natural forest have been converted into fast-growing pine plantations -- in fact, the U.S. Forest Service estimates that nearly twenty percent of Southern forests are now pine plantations. Nationwide the United States lost an average of 831 square miles of old-growth forest per year according to official figures, the seventh highest loss in the world.
