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.

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

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.

Germany: Snow and ice cause traffic chaos

Heavy snow and black ice caused traffic chaos across Germany on Wednesday morning, meanwhile more winter weather was expected throughout the day.

Snow storms in the lower mountain range of the Rhineland region, the state of North Rhine-Westphalia and the Taunus region in the state of Hesse brought traffic to a standstill during the morning commute. The sanitary department had been out in full force ploughing snow and salting streets, police said, adding that they still expected delays in heavy traffic areas.
