India's largest automaker, Tata Motors, announced this week it will partner up with MDI of France, a technology invention company, to develop engines powered by compressed air. Tata says the agreement "envisages Tata's supporting further development and refinement of the technology, and its application and licensing for India." MDI is the company behind The Air Car.

The way the Air Car's CAT (compressed air technology) works is that an "innovative system" - MDI isn't releasing true technical details because of corporate secrecy - controls the movement of four two-stage pistons (giving eight compression/expansion chambers) and a single crankshaft. A 5kW electric moto-alternator compresses air, recharges the battery, serves as an electric moderator/brake and as a temporary power supply (e.g. for parking).

That sounds positive, but reader Fabio Alemagna says the key problem for MDI's technology is the fundamental problem that the "fuel" conducts freeze thanks to the subzero temperature of the compressed air.

Tata is also working on engines powered by Hithane, a mix of hydrogen and compressed natural gas. For its part, MDI is not limiting itself to India or Tata. MDI president Guy Negre said his company was happy to work with Tata but, "We are continuing the development with our own business concept of licensing car manufacturers in other parts of the world where the production is located close to the markets."

Monsanto dumped toxic waste in UK

PCBs, Agent Orange derivatives, dioxins dumped by Monsanto in the environment 30 years ago. Shall we wait 30 years to condemned the obvious contamination impact of the GMO? J-L Roux

Inquiry after chemicals found at site 30 years after their disposal

Evidence has emerged that the Monsanto chemical company paid contractors to dump thousands of tonnes of highly toxic waste in British landfill sites, knowing that their chemicals were liable to contaminate wildlife and people. Yesterday the Environment Agency said it had launched an inquiry after the chemicals were found to be polluting underground water supplies and the atmosphere 30 years after they were dumped.

According to the agency it could cost up to £100m to clean up a site in south Wales that has been called "one of the most contaminated" in the country.

A previously unseen government report read by the Guardian shows that 67 chemicals, including Agent Orange derivatives, dioxins and PCBs which could have been made only by Monsanto, are leaking from one unlined porous quarry that was not authorised to take chemical wastes.

The Brofiscin quarry on the edge of the village of Groesfaen, near Cardiff, erupted in 2003, spilling fumes over the surrounding area, but the community has been told little about the real condition of what is in the pit. Yesterday the government was criticised for failing to publish information about the scale and exact nature of this contamination.

Douglas Gowan, a pollution consultant who produced the first official report into the Brofiscin quarry in 1972 after nine cows on a local farm died of poisoning, said: "The authorities have known about the situation for years, but have done nothing. There is evidence of not only negligence and utter incompetence, but cover-up, and the problem has grown unchecked."

Much of the new information about Monsanto's activities in Britain in the 1960s and early 1970s has emerged from court papers filed in the US and previously unseen internal company documents. They show how the company knew from 1965 onwards that the PCBs - polychlorinated biphenyls used mainly as flame retardants and insulaters - manufactured in the US and at its plant in Newport, south Wales, under the trade name Aroclor, were accumulating in human milk, rivers, fish and seafood, wildlife and plants.

The documents show that in 1953, company chemists tested the PCB chemicals on rats and found that they killed more than 50% with medium-level doses. However, it continued to manufacture PCBs and dispose of the wastes in south Wales until 1977, more than a decade after evidence of widespread contamination of humans and the environment was beyond doubt.

A high-level committee within the company was given the task in 1968 of assessing Monsanto's options and reported contamination in human milk, fish, birds and wildlife from around the world, including Britain. "In the case of PCBs the company is faced with a barrage of adverse publicity ... it will be impossible to deny the presence and persistence of Aroclors. The public and legal pressures to eliminate or prevent global contamination are inevitable and probably cannot be contained successfully," the committee reported.

The report, which was shown to only 12 people, said: "The alternatives are [to] say and do nothing; create a smokescreen; immediately discontinue the manufacture of Aroclors; respond responsibly, admitting growing evidence of environmental contamination ..." A scrawled note at the end of the document says: "The Big Question! What do we tell our customers ... try to stay in business or help customer's clean up their use?"

Monsanto stopped producing PCBs in the US in 1971, but the UK government, which knew of the dangers of PCBs in the environment in the 1960s, allowed their production in Wales until 1977.

Yesterday Monsanto, which has split into several corporate entities since 1997, said in a statement: "On behalf of [former parent company] Pharmacia Corp, Monsanto is handling issues related to the historical manufacture of PCBs in Wales. We continue to work with the Wales Department of Environment and other regulatory bodies to resolve these issues. A thorough review ... will show that Pharmacia did inform its contractors of the nature of wastes prior to disposal, and that Pharmacia did not dump wastes from its own vehicles."

Solutia, the spin-off from Monsanto which now owns the Newport site, said it was giving Monsanto and the regulatory agencies "information as requested".

The Environment Agency Wales said it was investigating the contents of the site: "This is one of the most contaminated sites in Wales and it is a priority to remediate because it is so close to habitations," said John Harrison, the agency's manager of the Taff/Ely region. "There is ground water pollution, but we do not think at present there is any danger to human health. We have spent about £800,000 so far investigating the tip. Our legal team is gathering all the evidence and we are trying to apportion costs."

Is industrial poultry a non sense?

Nobel prizewinners and campaigners called for the elimination of large scale intensive livestock farming

Some figures and facts

( see The Guardian click on the title)

- Britain's £3.4bn poultry industry, which produces 800 million birds a year
- UK produce 16 million chickens a week in this country and some 500,000 are not wanted
- UK is preparing very, very seriously and thoroughly for the possibility of a pandemic flu. It is a very remote risk, but if it did happen it could be very serious indeed.
- Nothing has given us any indication whatever that this event is linked directly to wild birds," said Lawrence Woodward, director of the Elm Farm Research Centre, who sits on the Defra committee of avian flu stakeholders. "The idea that a solitary bird carrying H5N1 is flying around East Anglia out of the migratory season and then falls down a ventilation shaft of the biggest poultry farm in Britain is just not viable," he said.
- The UN senior coordinator for avian flu and human influenza, David Nabarro, said in Indonesia that he expected an increase in bird flu around the world: "At the moment there are rather a lot of [cases] ... that is why everybody needs to be a little anxious about what is happening."
- In a letter to the Guardian, Nobel prizewinners and campaigners, including Noam Chomsky and Naomi Klein called for the elimination of large-scale intensive livestock farming which they argue is "accelerating the development of new pandemic diseases".

We cannot let the Kyoto debacle happen again

Some key cote of Sir King Charles - Chief scientific advisor of of Tony Blair
"
The message for policy-makers is clear: climate change is not a passing fancy for environmentalists. It represents a challenge on a scale that will affect societies and economies across the world."

"It is important to remember that, beyond the next two decades or so, the future severity of climate change and its impacts lies in our hands. We have the knowledge, technologies and capability to transform our economies, if we have the commitment to do so."

"it is not only governments that should hear these messages. As individuals, we can make adjustments that together can have a big impact. As consumers, we can transform markets through our purchasing choices. And as concerned citizens, we can encourage governments, nationally and locally, to show leadership."

"The IPCC's work is vital in providing a solid foundation of evidence on which these crucial decisions can be made. We have lost 17 years since Kyoto. Now we have to act."

Climate change: In graphics

It is "very likely" that human activity is the cause for climate change, scientists from over 130 countries have concluded. The graphics below illustrate their predictions on just how much global temperatures may rise over the next century.

The Intergovernmental Panel on Climate Change predicts that temperatures are most likely to rise by 1.8C-4C by 2100. But the possible range is much greater; 1.1C-6.4C. The maps above show how a range of three different scenarios will affect different parts of the planet.
The emissions scenarios, A1B, A2, B1, used to create the maps above, are based on a range of detailed economic and technological data. These versions of the future consider different population increases, fossil and alternative fuel use, and consequent CO2 increases. The broad range of outcomes they show is displayed in the charts below.



Carbon dioxide is the main greenhouse gas, its rise since the industrial revolution is clear. Burning coal, using oil and deforestation all place CO2 into the atmosphere.

Humans blamed for climate change

IPCC IVth Report Assessment: humans blamed for climate.

Even if the IVth report of the International Panel of Climate Change experts seems to be strong their is other scientist voices saying that the report seems below the thruth so a study published on the eve of the IPCC report suggested that the international body's previous reports may have actually been too conservative.

Writing in the journal Science, an international group of scientists concluded that temperatures and sea levels had been rising at or above the maximum rates proposed in the last report, which was published in 2001.

The paper compared the 2001 projections on temperature and sea level change report with what has actually happened.

The models had forecasted a temperature rise between about 0.15C-0.35C (0.27-0.63F) over this period. The actual rise of 0.33C (0.59F) was very close to the top of the IPCC's range.

A more dramatic picture emerged from the sea level comparison. The actual average level, measured by tide gauges and satellites, had risen faster than the intergovernmental panel of scientists predicted it would.

The IPCC's full climate science report will be released later in the year, as will other chapters looking at the probable impacts of climate change, options for adapting to those impacts, and possible routes to reducing emissions of greenhouse gases.
