    BREAKING NEWS: Global Warming Approaching Point Of No Return

    'Scary' science finds Earth heating up twice as fast as thought

    The largest ever climate-change experiment reveals that scientists may have dramatically underestimated the threat of global warming.

    The study by British scientists, which is published today, found the planet's global temperature could climb by between 2C and 11C because of skyrocketing levels of greenhouse gases such as carbon dioxide.

    That more than doubles the current prediction of a 1.4C to 4.5C rise this century.

    "When we started out we didn't expect anything like this," said Oxford University's David Stainforth, chief scientist for climateprediction.net.

    The project is a collaboration of experts at Oxford and Reading universities, The Open University, London School of Economics, Hadley Centre for Climate Prediction and Research, and Rutherford Appleton Laboratory.

    The findings are published in the journal Nature.

    "If this is the case, it's very dramatic and very scary," Mr Stainforth said.

    Even rises that are more modest are expected to trigger disastrous changes, including melting glaciers, sea-level rises, shut-down of the Gulf Stream, and increases in droughts, cyclones and other extreme weather events. The new results follow two reports in last week's edition of Science, showing that global warming probably caused the "Great Dying".

    Although that was the worst extinction in Earth's history - wiping out more than 90 per cent of all life - it involved gradual extinctions over about 10 million years, culminating in a sharp extinction pulse 250 million years ago. Further concern comes from an international report released in London last Monday. It warned that climate change could kick in within 10 years, unless greenhouse gas emissions are cut.

    The initial goal of climateprediction.net was to evaluate the sensitivity and variables of the Hadley computer model of climate change.

    In order to obtain their findings, Mr Stainforth and his colleagues ran 50,000 climate simulations.

    Because so much computing power was needed, they relied on help from 90,000 people from 150 countries to run the programs on their personal computers.

    More than 1200 Australians, such as Melbourne academic Nick Hoffman, participated. "I'm interested in the dynamics of planetary atmospheres, so it was well worth supporting (the project)," Dr Hoffman said.

    According to Neville Nicholls, head of climate forecasting at the Bureau of Meterology in Melbourne, climateprediction.net is a "terrific project" that tackles the uncertainty of climate predictions. He agreed with CSIRO climate modeler Tony Hirst that: "This may mean that the world could warm up faster than most of us are happy anticipating."

    Global warming approaching point of no return, warns leading climate expert

    Global warning has already hit the danger point that international attempts to curb it are designed to avoid, according to the world's top climate watchdog.

    Dr Rajendra Pachauri, the chairman of the official Intergovernmental Panel on Climate Change (IPCC), told an international conference attended by 114 governments in Mauritius this month that he personally believes that the world has "already reached the level of dangerous concentrations of carbon dioxide in the atmosphere" and called for immediate and "very deep" cuts in the pollution if humanity is to "survive".

    His comments rocked the Bush administration - which immediately tried to slap him down - not least because it put him in his post after Exxon, the major oil company most opposed to international action on global warming, complained that his predecessor was too "aggressive" on the issue.

    A memorandum from Exxon to the White House in early 2001 specifically asked it to get the previous chairman, Dr Robert Watson, the chief scientist of the World Bank, "replaced at the request of the US". The Bush administration then lobbied other countries in favour of Dr Pachauri - whom the former vice-president Al Gore called the "let's drag our feet" candidate, and got him elected to replace Dr Watson, a British-born naturalised American, who had repeatedly called for urgent action.

    But this month, at a conference of Small Island Developing States on the Indian Ocean island, the new chairman, a former head of India's Tata Energy Research Institute, himself issued what top United Nations officials described as a "very courageous" challenge.

    He told delegates: "Climate change is for real. We have just a small window of opportunity and it is closing rather rapidly. There is not a moment to lose."

    Afterwards he told The Independent on Sunday that widespread dying of coral reefs, and rapid melting of ice in the Arctic, had driven him to the conclusion that the danger point the IPCC had been set up to avoid had already been reached.

    Reefs throughout the world are perishing as the seas warm up: as water temperatures rise, they lose their colours and turn a ghostly white. Partly as a result, up to a quarter of the world's corals have been destroyed.

    And in November, a multi-year study by 300 scientists concluded that the Arctic was warming twice as fast as the rest of the world and that its ice-cap had shrunk by up to 20 per cent in the past three decades.

    The ice is also 40 per cent thinner than it was in the 1970s and is expected to disappear altogether by 2070. And while Dr Pachauri was speaking parts of the Arctic were having a January "heatwave", with temperatures eight to nine degrees centigrade higher than normal.

    He also cited alarming measurements, first reported in The Independent on Sunday, showing that levels of carbon dioxide (the main cause of global warming) have leapt abruptly over the past two years, suggesting that climate change may be accelerating out of control.

    He added that, because of inertia built into the Earth's natural systems, the world was now only experiencing the result of pollution emitted in the 1960s, and much greater effects would occur as the increased pollution of later decades worked its way through. He concluded: "We are risking the ability of the human race to survive."

    I like how the Bush administration tries to fight all this. And all his supporters agree with him.

    One percent of the population is worried about stuff like this, the rest don't give a shit. We are all outnumbered here and will never win. The rich will bury us all.

    "The Rich Will Bury Us All" That's a good title for a thread.

    I think it should replace the phrase "In God We Trust".
