Study: Asteroid Breakup Likely Cause Of Mass Earth Extinction

Boulder, Colo. — New research says it started as an asteroid vs. asteroid collision and breakup far above earth, and got worse from there, with large chunks eventually striking earth and the moon. After years of analysis and computer modeling, scientists now believe the impact that wiped out dinosaurs and other life forms on Earth some 65 million years ago began with a breakup event in the main asteroid belt. A joint U.S.-Czech team from Southwest Research Institute and Charles University in Prague thinks the parent object of asteroid (298) Baptistina broke up when it was hit by another large asteroid.
More CO2, Plants Less Thirsty, Rivers Higher
September 9, 2007 12:15 PM - Paul Schaefer, ENN
University of Exeter, UK - Rising carbon dioxide levels will increase river levels in the future, according to a team of scientists from the Met Office Hadley Centre, the University of Exeter and the Centre for Ecology & Hydrology. The findings, published on 30 August 2007 in the journal Nature, suggest that increasing carbon dioxide will cause plants to extract less water from the soil, leaving more water to drain into rivers which will add to the river flow increases already expected due to climate change.
In A Warmer World, Birch Trees Will Edge Out Aspens
September 9, 2007 12:03 PM - University of Michigan News
ANN ARBOR, Michigan — Birches will likely drive out many aspens in northern forests as mounting levels of carbon dioxide force the trees to compete more fiercely for soil nutrients in the coming decades, a University of Michigan researcher and his colleagues have concluded. Carbon dioxide is emitted when fossil fuels are burned, and it's a heat-trapping gas blamed for global warming. But rising carbon dioxide levels also have a fertilizing effect on trees and other plants, making them grow faster than they normally would.

PBS Documentary: The Silence Of The Bees
September 9, 2007 10:52 AM - Paul Schaefer, ENN
NEW YORK, - From crop fields to hi-tech labs, scientists and bee experts are investigating a rapidly unfolding ecological nightmare. The Silence of the Bees premieres on Sunday, October 28 at 8 p.m. eastern on PBS (check local listings). Academy Award-winning actor F. Murray Abraham narrates the series. It was shot on high definition cameras. Honeybees are responsible for one of every three bites of food we eat. Each year, they pollinate $14 billion worth of crops and seeds in the U.S. alone. Their total decimation would be catastrophic from the local to the global level -- failed businesses, skyrocketing food prices, unsustainable labor costs, and depleted supplies of fruits, nuts, vegetables, plants, and more.

In a half-hour address released four days before the sixth anniversary of the September 11 attacks on the United States, bin Laden lurched between history lesson and sermon, urging Americans to ditch capitalist democracy and embrace Islam if they want to end the war in Iraq.
