Rising tides intensify non-volcanic tremor in Earth's crust
November 23, 2007 09:01 AM - University of Washington

For more than a decade geoscientists have detected what amount to ultra-slow-motion earthquakes under Western Washington and British Columbia on a regular basis, about every 14 months. Such episodic tremor-and-slip events typically last two to three weeks and can release as much energy as a large earthquake, though they are not felt and cause no damage.

KIEV (Reuters) - Sulphur from two ships that sank in a storm near the Black Sea last week is leaking into waters already polluted by an oil spill from another vessel, UkraIne's Environment Ministry said on Monday.

Four ships sank in the Kerch Strait on the northern mouth of the Black Sea in one of the worst storms in a century. They included a Russian-registered tanker which disgorged hundreds of tons of oil, creating a environmental disaster for the area's delicate ecology.

White-Tailed Eagle Back from the Brink
November 19, 2007 08:56 AM - Robert, Environmental Graffiti

The white-tailed eagle, once on the brink of extinction in Britain, has bounced back.

The eagle now has 42 breeding pairs on the west coast of Scotland, six more than last year’s total. This year’s breeding has resulted in 34 young birds. The total of all birds is close to 200.

The bird was once extinct in Britain after the last bird was shot in 1918, but the bird was reintroduced into the country in 1975 and it has done well so far. The massive bird has an eight-foot wingspan and is Britain’s largest bird of prey. It is also known as the sea eagle.

Delay in Autumn Colour is Caused by Increased Atmospheric CO2 not Global Warming
November 19, 2007 08:44 AM - University of Southampton

The delay in autumnal leaf coloration and leaf fall in trees is caused by rising levels of carbon dioxide (CO2) in the atmosphere and not by increased global temperatures, suggests a new study by researchers at the University of Southampton.

In recent years, woodland autumnal colour changes have been occurring later in the season whilst re-greening in spring has been occurring earlier. During the last 30 years across Europe, autumnal senescence – the process of plant aging where leaves discolour and then fall – has been delayed by 1.3 - 1.8 days a decade. To date, this has been explained by global warming, with increasing temperatures causing longer growing seasons.
