Glimmer of hope for rare monkey

A new sub-population of a Critically Endangered species of monkey has been recorded in north-western Vietnam.

Biologists from Fauna and Flora International said they had found up to 20 Tonkin snub-nosed monkeys in a remote forest.

The team said the new group offered a ray of hope because it included three infants, suggesting that the monkeys were breeding and increasing in number.

The behemoth that wouldn't stop growing

Have you noticed that we describe the market and economy as if they were living entities? The market is showing signs of stress. The economy is healthy. The economy is on life support.

Sometimes, we act as if the economy is larger than life. In the past, people trembled in fear of dragons, demons, gods, and monsters, sacrificing anything - virgins, money, newborn babies - to appease them. We know now that those fears were superstitious imaginings, but we have replaced them with a new behemoth: the economy.

Even stranger, economists believe this behemoth can grow forever. Indeed, the measure of how well a government or corporation is doing is its record of economic growth. But our home - the biosphere, or zone of air, water, and land where all life exists - is finite and fixed. It can't grow. And nothing within such a world can grow indefinitely. In focusing on constant growth, we fail to ask the important questions. What is an economy for? Am I happier with all this stuff? How much is enough?

Comment: The 'brain damage" is more correctly defined as pyschopathy. Psychopaths have no sense of long-term consequences. They're hard-wired to pay attention only to their own desires and goals, without considering the wider ramifications of those goals.

Colder Manitoba winter predicted

Winter in Winnipeg
With more snow to boot

Will we freeze in our boots or skate through a mild winter?

Weather forecasters say parts of Manitoba might be in store for cooler than normal temperatures from now through February with more precipitation than usual this winter.

"We're saying this will be a colder than normal year," said David Phillips, senior climatologist for Environment Canada.

The weather agency doesn't predict exactly how much colder the winter might be but Phillips said it could be similar to last winter, which ran about one degree colder than normal.

Mystery of crocs' mass die-off

Some gharials may be feeding on fish that have large toxic loads
Measuring up to 6m long, with elongated narrow snouts, gharials are one of the world's most distinctive-looking crocodilians.

Just 100 years ago, these fish-eating reptiles were prevalent throughout the Indian subcontinent; but by 2007, there were just 200 breeding adults found in only a handful of rivers in India and Nepal.

Last winter, this already critically endangered species was dealt another cruel blow. Over the space of just five months, more than 100 of the creatures washed up dead on the banks of India's Chambal river - and nobody knew why.

For the past year, herpetologist Rom Whitaker, who runs the Madras Crocodile Bank, has been followed by a BBC Natural World team as he attempted to solve this mystery.

Did Greenhouse Gases Cause the Earth's Greatest Mass Extinction?

In 1980, scientists Luis Alvarez and his son, Walter, proposed a new explanation for the dinosaurs' disappearance 65 million years ago: a meteor strike. Initially, the idea was met with resistance. But the evidence was convincing: a sediment layer high in iridium, an element common in asteroids, was found the world over, along with a 110-mile-wide impact crater in the Yucatán of the same age. What started as a fringe idea has gone mainstream.

Now scientists are rethinking another of earth's great die-offs. The end-Permian extinction 251 million years ago was the worst of earth's five mass extinctions. Ninety percent of all marine life and 70 percent of terrestrial life disappeared. It took five million years, perhaps more, for the biosphere to recover.

But while the die-off was uniquely devastating, evidence of a single cataclysmic event, like an asteroid strike, hasn't been found in the geological record. Scientists now suspect that "the mother of all mass extinctions" was of Earth's own making. And the more they learn about it, the more parallels they see to today's world: A bout of greenhouse-gas-induced global warming, much like today's, set off a chain of events that culminated in oxygen-depleted oceans exhaling poison gas.

Comment: Notice the tactic of linking some good science with the subtle reassurance that "the asteroids (or comets) are not to blame". Besides "who sez" that the oceans can't become anoxic in conditions of global cooling?

Conservation atlas reveals 'most valuable' forest

A new atlas shows how conservation efforts can most efficiently make use of limited resources by laying out which forests store large amounts of carbon and are also home to a great diversity of animals and plants.

The UN Environment Programme, which released the maps at the ongoing UN climate summit in Poznan, Poland, believes they could guide investments in forest conservation.

"At a time of scarce financial resources and economic concerns, every dollar, euro or rupee needs to deliver double, even triple dividends," says Achim Steiner, executive director of UNEP. "By pinpointing where high densities of carbon overlap with high levels of biodiversity, the atlas spotlights where governments and investors can deal with two crises for the price of one."

Colombia: Deforestation and Deluge, a Recipe for Disaster

The lack of policies against indiscriminate deforestation in river basins, in synergy with the rainy season, which is heavier than usual this year because of the La Niña climate phenomenon, has had devastating effects in Colombia.

This "winter," as the rainy season is called in this country, there have already been 600 local disasters caused by gale-force winds and constant, heavy rainfall. Rivers have burst their banks, and landslides and avalanches of all kinds have occurred, meteorologist Max Henríquez told IPS.

The rains began in September and will probably only let up in mid-December, because of La Niña. "Throughout 2007 and for several months this year we have experienced this climate phenomenon, caused by the cooling of the surface waters in the Pacific ocean, which brings above normal rainfall," the meteorologist said.

US: Rain, Not Dam Malfunction, Caused June Indiana Floods

A report shows that torrential rain, not a dam malfunction, caused the flooding in June that affected one of every seven structures in Columbus, Indiana.

A report from the U.S. Geological Survey summarized reasons for the event, detailed its effects and illustrated its severity with maps, charts and rainfall data. City Engineer Steve Ruble says the study eliminates the possibility of a "smoking gun'' and proves the flooding came from rainfall on June 6 and 7.

UK: Thousands Of Homes Lose Power

Thousands Of Homes Lose Power
The Army was mobilised to help stricken drivers as heavy snow brought traffic chaos and cut power to thousands of homes in northern England.

Hundreds of schools were closed across Northern England and Scotland.

As much as 20cm of snow fell in the Durham Dales, and 17cm was recorded at Redesdale, Northumberland, with driving winds causing drifts on transpennine routes in what was the heaviest snowfall of the winter so fall.

Around 4,450 homes were without power in north-east Yorkshire and north Linclonshire by early evening.

Are climate scientists overselling their models?

At the UN climate negotiations under way in Poland this week, politicians will be poring over forecasts of climate change. It's an opportune moment for physicist Lenny Smith to challenge the climate modellers who he believes are overselling their results. Human activity really is changing the global climate, he tells Fred Pearce, but we must stop pretending that we know the details of how it will all play out

Physicist Lenny Smith thinks that climate modellers are overselling their results.

You work with climate models, but you have issues with them too. Why?

The temptation to interpret model noise as forecast information invades our living rooms every night. TV weather-forecast maps look so realistic it is hard not to over-interpret tiny details - to imagine that the band of rain passing over Oxfordshire at noon next Saturday requires postponing a barbecue. Rain may indeed be likely somewhere in the area sometime on Saturday, but the details we see on TV forecasts are noise from the models. I think we are having exactly the same problem with climate projections.
