BEIJING (Reuters) - Large areas of south China are suffering from serious drought, with water levels on two major rivers in rice-growing provinces dropping to historic lows, state media said on Tuesday.

Rainfall since the beginning of October had dropped by 90 percent in Jiangxi and 86 percent in neighboring Hunan, the country's largest rice-growing province, from average figures, Xinhua news agency said.

Wrecked Black Sea ships start to leak sulphur

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

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.

Act Now on Climate Change: Go For Energy Efficiency.
November 19, 2007 08:06 AM - , Private Landowner Network

The latest report on the state of global warming from the Intergovernmental Panel on Climate Change ((IPCC) warns that without action soon climate change may cause abrupt and irreversible impacts.

(Glaciers, like those on Greenland, may experience rapid meltdown and cause sea levels to rise. Once gone glaciers won’t freeze up again. Droughts similar to that now being experienced in the southeast US may be more frequent and perhaps permanent. Populations without water to support them will have to move, never to return.)

Iron is a tonic for climate-saving plankton

Noah's Ark flood spurred European farming
November 17, 2007 07:19 PM - Reuters

LONDON (Reuters) - An ancient flood some say could be the origin of the story of Noah's Ark may have helped the spread of agriculture in Europe 8,300 years ago by scattering the continent's earliest farmers, researchers said on Sunday.

Using radiocarbon dating and archaeological evidence, a British team showed the collapse of the North American ice sheet, which raised global sea levels by as much as 1.4 meters, displaced tens of thousands of people in southeastern Europe who carried farming skills to their new homes.

The researchers said in the journal Qua
