HERE are the 100 reasons, released in a dossier issued by the European Foundation, why climate change is natural and not man-made:

Three in four British voters believe Gordon Brown and world leaders are on an important mission at the climate change conference in Copenhagen, according to a new Guardian/ICM poll.

Voters overwhelmingly reject the view of climate change sceptics that world leaders "are panicking about an exaggerated threat". But close to half of the electorate believes that the leaders - including Brown, who arrives at the summit today - need to worry about economic growth, too

We've long had a problem with preventative policing in the UK - it is something I have been subject to, and have campaigned against. However, the level of repressive policing displayed in arresting more than 1,000 people at the weekend in Copenhagen far exceeded anything we have experienced in this country.

I joined the march as a police observer, my aim being to monitor events and compare how the Danish police treated protesters. I was near the back of the march. There was a large contingent of people wearing black hoodies, some anarchist flags were waving, but where I was, there was no trouble. The atmosphere was good, and my friend and I commented on how lovely it was to see so few police officers on such a large demo.

Nasa satellites have weighed the water lost by the US State of California's heartland since 2003.

The Sacramento and San Joaquin River Basins which support the highly productive Central Valley have shed over 30 cubic km of water in that time.

The data comes from the Grace mission which detects changes in gravity caused by water as it cycles between the sea, the atmosphere and the land.

It illustrates the impact of a drought but also excessive irrigation use.

The head of a geothermal energy company has gone on trial in Switzerland accused of damaging property by triggering earthquakes.

Markus Haering's company had been working with the authorities in Basel to try to convert the heat in deep-seated rocks into electricity.

But the project was suspended in 2006 when drilling triggered the quakes.

They caused no injuries but led to $9m (£5.54m) of damage. Mr Haering denies deliberately damaging property.

The project was shut down permanently last week after a government study found that similar quakes caused by the project would lead to millions of dollars worth of damage each year.

Scientists at NASA's Langley Research Center have completed a first attempt to accurately calculate the level of damaging radiation flight crews and passengers are exposed to on commercial airline flights. The work is an early step toward developing a model to observe radiation exposure for all commercial flights, particularly for pilots and crews who spend their careers airborne and who are at greater risk of developing certain cancers.

The study considered not only everyday radiation emanating from space, but also the additional energy unleashed during a solar storm, which can be profound. NASA scientists say not including geomagnetic effects on solar radiation in modeling radiation exposure could underestimate the dosage by 30 to 300 percent.

NASA researchers studying urban landscapes have found that the intensity of the "heat island" created by a city depends on the ecosystem it replaced and on the regional climate. Urban areas developed in arid and semi-arid regions show far less heating compared with the surrounding countryside than cities built amid forested and temperate climates.

"The placement and structure of cities -- and what was there before -- really does matter," said Marc Imhoff, biologist and remote sensing specialist at NASA's Goddard Space Flight Center in Greenbelt, Md. "The amount of the heat differential between the city and the surrounding environment depends on how much of the ground is covered by trees and vegetation. Understanding urban heating will be important for building new cities and retrofitting existing ones."

Cameron's £20bn plan for green homes | Politics | The Guardian

David Cameron has pledged that a Conservative government would from "day one" kickstart £20bn of investment to make millions of homes more energy-efficient in a groundbreaking green partnership with Tesco and Marks & Spencer.

In a Guardian interview to coincide with the critical stage of the Copenhagen summit, the Tory leader reveals the plan to let householders share in the savings made on their power bills with the high street names who provide them with lagging and insulation.

He says he has already signed up a group of local councils and the mayor of London, Boris Johnson, for the scheme which would tackle more than 30% of UK carbon emissions by offering six million households the chance to get £6,500 worth of energy-efficiency measures.

Cameron sees the idea for a "localist green revolution" as an answer to his fear that what he describes as the current top- down climate change agenda is "in danger of starting to lose people".

COPENHAGEN -- Negotiators have all but completed a sweeping deal that would compensate countries for preserving forests, and in some cases, other natural landscapes like peat soils, swamps and fields that play a crucial role in curbing climate change.

... The authorities say it is impossible to quantify the level of fraud in public spending on wind energy because investigations are scattered across different countries among the regional and fiscal police. But critics say the available riches and patchy controls are luring a rogue's gallery of corrupt politicians and entrepreneurs trying to literally create money out of thin air.

<...>

The European Wind Energy Association -- which represents 600 manufacturers and members in 60 countries, including some outside of Europe, and which attracted more than €10.9 billion last year in investments -- argues that problems with corruption are rare and that industry regulation is not needed.

"We have fraud legislation in all countries, and this is a matter for the national police," said Christian Kjaer, chief executive of the trade group.

But critics like John Etherington, a former professor of ecology at the University of Wales and author of "The Wind Farm Scam," contends that because the industry is so dependent on subsidies, it is highly vulnerable to scams. Mr. Etherington said that he is "not sure that the industry is regulated at all -- let alone well regulated." ...

Reporting from Lijiang, China - If you want to see a glacier melt with your bare eyes, try Yulong Snow Mountain, an 18,000-foot peak in southern China's Yunnan province. On this early December morning, the mountain is etched against the technicolor sky in shades of gray -- definitely more gray than white. Naked boulders of limestone and daubs of shrubbery protrude from the shallow snow cover.

In the study of climate change, glaciers are sometimes likened to the canaries in the coal mine, and to many observers the condition of Yulong ("Jade Dragon") mountain is troubling. He Yuanqing, one of China's leading glacier experts, found that the mountain's largest glacier, known as Baishui No. 1, has retreated about 275 yards since 1982.

....

Anywhere from five to 20 scientists work here at any given time -- planting sticks in the drifts to measure snow accumulation and taking time-lapse photographs of the retreating snows and the advancing tree line up the mountain. Yulong Snow Mountain is a fitting object for their obsession: It has the southernmost glaciers on the Eurasian continent. Its location at the edge of the Tibetan plateau is also critical.

....

The Tibetan plateau is also extremely vulnerable to global warming. The China Meteorological Administration calculates that temperatures on the plateau have risen an average of 0.58 degrees Fahrenheit per decade, more than four times the average warming rate in China as a whole.

....

When glaciers disappear, they don't necessarily go quietly. The ice becomes unstable; gentle slopes of snow erode into steep ridges that can collapse at unpredictable times. Yulong has had two such avalanches recently -- one in 2004 and another over the summer.
