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

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.

Over 200 inches of snow greets Alyeska skiers and riders

Yes you read that right - over 200 inches - 16.7 feet! - of snow. And 117 inches of the total came in the last week at Alyeska Resort, about 40 miles south of Anchorage, Alaska.

Alyeska opened for business on November 26 and according to a press release, with "epic conditions that rival the best opening day on record."

Super-Ant Taking Over Europe

An ant species that originated in the Black Sea region has invaded more than 100 areas across Europe and is moving north. Scientists say if it is not stopped, it will reach northern Germany, Scandinavia and Britain and could invade the whole world.

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.

Megathrust earthquake could hit Asia 'at any time'

A devastating "megathrust" earthquake could occur at any time off the Indonesian island of Sumatra, according to new research. Previous quakes have failed to release all of the energy that has built up over hundreds of years, leaving the fault zone vulnerable to another large earthquake.

Using GPS, field measurements, radar data and seismological records, a team of international researchers investigated the parameters and reconstructed the events of two massive earthquakes, measuring 8.4 and 7.9 on the Richter scale, which occurred in the Mentawai area in 2007.

Previous models of how earthquakes work had suggested that the same fault would rupture in the same way and at regular, predictable time intervals. But the researchers found that the 2007 quakes ruptured only a fraction of the area affected by the giant 1833 earthquake, indicating that a tectonic plate boundary can rupture in different patterns depending on local differences in stress.
