'Climate dice' now dangerously loaded: leading scientist

Use traditional methods to fight global warming: UN group
Rome (AFP) May 12, 2010 - Centuries-old techniques to prevent desertification, energy wastage and other problems should be enlisted in the fight against global warming, a new UN-backed group said Wednesday. Traditional water management methods from the Sahara and Ethiopia and Iraq's Babylon area could be used alongside newer technologies such as solar power, the group said at its launch in Florence, central Italy. "Traditional knowledge and its innovative use is the basis for sustainable technology, and essential for the development of a new model of human progress," said Pietro Laureano, founding president of the UN-backed International Traditional Knowledge Institute (ITKI).

"With climate change, we are obliged to come back to systems that save energy, that don't need much capital," Laureano, an anthropologist, landscape architect and consultant to UNESCO on desertification, told AFP by telephone. Laureano said he had studied techniques such as rainwater capture systems, rooftop gardens and underground tunnels that keep water in the subsoil, but that they risk extinction with the advent of intensive agriculture. "The deep trenches used for example in Lalibela, northern Ethiopia, were abandoned, and now (it) has no water," he said. "Now they depend on technology and industrial systems," he said, adding that the fact the traditional methods are labour intensive is "not a problem -- there's unemployment."

Laureano said the group still backed "appropriate" new technology such as solar power, adding: "What is appropriate today will be the traditions of tomorrow." ITKI, to be based in Bagno a Ripoli east of Florence, was set up under the authority of the UN Educational, Scientific and Cultural Organisation (UNESCO). Its remit is "safeguarding and validating traditional knowledge" with the primary goal of combatting global warming, but also encouraging the protection of cultural heritage such as folklore, music and symbolism, Laureano said. The institute will also "work with indigenous peoples... to protect their rights and not allow corporations to make patents on their knowledge," he said.

Paris (AFP) May 12, 2010
Evidence for global warming has mounted but public awareness of the threat has shrunk, due to a cold northern winter and finger-pointing at the UN's climate experts, a top scientist warned Wednesday.

James Hansen, a leading NASA scientist whose testimony to the US Congress in 1988 was a landmark in the history of climate change, said he was worried by "the large gap" in knowledge between specialists and the public, including politicians.

"That gap has increased substantially in the last year," Hansen told a press conference during a visit to Paris.

"While the science was becoming clearer, the public's perception became less clear, in part because of the unusually cold winter in both North America and Europe, and in part because of the inappropriate over-emphasis on small minor errors in IPCC documents and because of the so-called Climategate."

The IPCC -- the UN's Intergovernmental Panel on Climate Change -- is under fire for several errors that appeared in a key 2007 report.

Its authors have acknowledged the mistakes, but say the overall conclusions of the report, that man-made greenhouse gases are changing the climate, remain solid.

The "Climategate" affair relates to stolen emails exchanged among British scientists that, sceptics said, showed they had ignored evidence that natural, rather than man-made, causes were to blame for climate change.

The scientists have been cleared by a British parliamentary panel.

"The winter was not cold if you look over the whole world: December, January, February was the second warmest in 130 years," Hansen noted.

"It was cool at mid-latitudes in the northern hemisphere but unusually warm in the Arctic and that has a simple explanation: there is a chaotic variation in the pressure in the Arctic region. But it's just chaotic variation, there is no reason that it will be repeated."

He added: "We have to look at the frequency of events. Seven out of the last 10 winters in Europe have been warmer than the long-term average, and eight out of 10 in the United States.

"So the climate dice are being loaded at a rate which is in very close agreement with what was predicted ago a few decades ago based on the expected global warming."

Hansen is director of NASA's Goddard Institute for Space Studies, but stressed he was speaking in a private capacity.

He blasted governments for "ignoring... basic scientific facts" by continuing to depend on fossil fuels, build more coal-fired plants and drill for oil in the deep ocean and the Arctic.

And he said that the poor outcome of December's climate summit in Copenhagen was predictable.

"Frankly, there was a realisation that you can't have 180 countries making the initial agreement, it has to be the major players. So, Europe, the US and China, and probably India, need to agree that there needs to be a carbon price and then it's very easy to make that global."

University Experts Prove British Summer Is Advancing
Norton, UK (SPX) May 10, 2010
The onset of summer in England has been advancing since the mid 1950s, research from a pair of University of Sheffield geographers has shown. The investigations, conducted by Amy Kirbyshire, a former undergraduate of the University, and Professor Grant Bigg, Head of the Department of Geography at the University, examined records of the first blooming date of early summer flowering plants ( ... read more
