    CO2 causing seas to turn to acid

    Hey Prowne, explain away this one:


    http://environment.independent.co.uk...cle3172144.ece

    Scientists have found that the seas have already absorbed about half of all the carbon dioxide emitted by humanity since the start of the industrial revolution, a staggering 500 billion tons of it. This has so far helped slow global warming which would have accelerated even faster if all this pollution had stayed in the atmosphere, already causing catastrophe but at an increasingly severe cost.

    The gas dissolves in the oceans to make dilute carbonic acid, which is increasingly souring the naturally alkali seawater. This, in turn, mops up calcium carbonate, a substance normally plentiful in the seas, which corals use to build their reefs, and marine creatures use to make the protective shells they need to survive. These include many of the plankton that form the base of the food chain on which all fish and other marine animals depend.

    As the waters are growing more acid this process is decreasing, with incalculable consequences for the life of the seas, and for the fisheries on which a billion of the world's people depend for protein. Every single species that uses calcium in this way, that has so far been studied, has been found to be affected. And the seas are most acid near the surface, where most of their life is concentrated.

    A report by the Royal Society, Britain's premier scientific body, concludes that, as a result, of the pollution, the world's oceans are probably now more acidic that they have ever been in "hundreds of millennia", and that even if emissions stopped now, the waters would take "tens of thousands of years to return to normal".

    Professor Ulf Reibesell of the Leibnitz Institute of Marine Sciences in Kiel, Germany's leading expert on the process, concludes in an issue of UNEP's magazine Our Planet, to be published next month, that, if it continues to the levels predicted by yesterday's report for the end of the century, the seas will reach a condition unprecedented in the last 20 million years.

    He recalls how something similar happened when a comet hit Mexico's Yucatan peninsula 65 million years ago, blasting massive amounts of calcium sulphate into the atmosphere to form sulphuric acid, which in turn caused the extinction of corals and virtually all shell-building species.

    "Two million years went by before corals reappeared in the fossil record," he says, adding that it took "a further 20 million years" before the diversity of species that use calcium returned to its former levels.

    Scientists add that, as the seas become more acidic, they will be less able to absorb carbon dioxide, causing more of it to stay in the atmosphere to speed up global warming. Research is already uncovering some signs that the oceans' ability to mop up the gas is diminishing. Environmentalists point out that the increasing acidification of the oceans would in itself provide ample reason to curb emissions of carbon dioxide from burning fossil fuels and felling forests even if the dwindling band of sceptics were right and the gas was not warming up the planet.

    But yesterday's cautiously worded report, which was agreed by the US government, also provides ample evidence that climate change is well under way, and is accelerating. It concludes that the warming is now "unequivocal" and "evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level".

    It adds: "Eleven of the last 12 years rank among the 12 warmest years in the instrumental record of global surface temperature". It goes on: "Observational evidence from all continents and most oceans shows that many natural systems are being affected by regional climate changes, particularly temperature increases."

    If humanity were not affecting the climate, it concludes, declines in the sun's activity and increased eruptions from volcanoes which throw huge amounts of dust in the air that screen out sunlight would have been likely to "have produced cooling" of the planet.

    But emissions of all the "greenhouse gas" pollutants that cause global warming increased 70 per cent between 1970 and 2004 alone, it reports, adding that levels of carbon dioxide, the most important one, in the atmosphere now "exceed by far" anything that the Earth has experienced in the past 650,000 years. And it goes on to conclude that "continued greenhouse gas emissions at or above current rates would cause further warming and induce many changes in the global climate system during the 21st century."

    It makes a host of specific predictions for every continent (for examples, see graphic) and warns that "impacts" could be "abrupt" or "irreversible". One example of an irreversible impact is an expected extinction of between 20 and 30 per cent of all the world's species of animals and plants even at relatively moderate levels of warming. If the climate heats further, it adds, extinctions could rise to 40 to 70 per cent of species.

    The IPCC scientists and governments say that they are also more concerned about "increases in droughts, heatwaves and floods" as the climate warms. They believe that the damage to the world's economy would be even greater than they had previously predicted, and were even more certain that the poor and elderly in both rich and poor countries would suffer most.

    Yet the report also concludes that, while some climate change is now inevitable, its worst effects could be avoided with straightforward measures at little cost if only governments would take action. It says that the job can be done by using "technologies that are either currently available or expected to be commercialised in coming decades". It could be done at a cost of slowing global growth by only a tenth of a percentage point a year, and might even increase it.

    The missing element, virtually everyone agrees, is political will from governments. Next month they meet in Bali to start negotiations on a new treaty to replace the current provisions of the Kyoto Protocol, which run out in 2012.

    The timetable is desperately tight; time lags in the process of getting a new treaty ratified by the world's governments means that it will have to be agreed by the end of 2009 and there is no sign of anything on the horizon.

    Yet the treaty will have to go far beyond the protocol in order to put the whole world on track rapidly to reduce emissions if the world is to achieve the pollution cuts that the scientists say will be needed to avoid catastrophe. And it will have to ensure rapid action. Dr Rajendra Pachauri, the IPCC's chairman, yesterday repeated a consensus among experts that the world as a whole will have to start radical reductions within eight years if there is to be any hope of preventing dangerous climate change.

    Stephanie Tunmore of Greenpeace International said: "It is clear from this report that we are gambling with the future of the planet and the stakes are high. This document sets out a compelling case for early action on climate change."

    The UN Secretary-General, agreed. The effects of climate change have become "so severe and so sweeping" he said "that only urgent, global action will do. There is no time to waste."

    Mr Steiner called the report "the most essential reading for every person on the planet who cares about the future". He added: "The hard science has been distilled along with evidence of the social and economic consequences of global warming, but also the economic rationale and opportunities for action now. While the science will continue to evolve and be refined, we now have the compelling blueprint for action and, in many ways, the price tag for failure from increasing acidification of the oceans to the likely extinction of economically important biodiversity."

    And Yvo de Boer, the executive secretary of the UN Framework Convention on Climate Change the parent treaty to the Kyoto Protocol told the IoS that reaching agreement was "incredibly urgent".

    He pointed out that the world would replace 40 per cent of its power generation capacity in the next five to 10 years and that China is already building one or two coal- fired power stations a week. Those installations would last for decades and the nations that built them would be reluctant to demolish them any earlier so that unless the world rapidly changed direction it would be all the more difficult to avoid climate change running out of control.

    Too much nonsense to respond to. They see most people don't give a %#$@ about global warming so they throw out this red herring to see if it sticks. It's kinda funny, really.:

    Wow. That is an extremely annoying post, Philliper. I can read, you don't need to set the font to moron size.

    How about you like, point out what is wrong with the science (if you can) instead of just sounding like an idiot?

    That is my problem with the whole "get US sign environmental pack debate" and "without US nothing will get done". As long as China keeps building those plant, nothing that US will do would make any effect on total CO2 levels.

    And China is saying the same thing, unless the US gets involved nothing that China does will have any effect on CO2 levels. Someone needs to act first, and the US is in a far better position to do so, and could do with ending their dependence on the middle east as well.

    You got it all wrong. US is running trade deficites not China. US has low growth rate, not China. And curbing coal usage will only increase our dependance on oil.

    Re: CO2 causing seas to turn to acid

    Do not worry about it, it is already too late, the amount of CO2 that can be absorbed in sea water is dependent on the temperature of the water, it will not be long now until water temperature exceeds the temperature, at which CO2 can exist in sea water.
    When the CO2 is released the methyl hydrates will follow, and we kiss human civilization good bye.
    It is probably already to late this debate should have happened decades ago.
    It is a wise man that plants a tree that generations shall harvest fruit from.
    It is a stupid man that cuts all the trees burns them plows the ground and creates a desert where generation of children will starve.
    Unfortunately human civilization in the past has been more stupid than wise, that can be seen in the civilizations that failed and are failing again today.

    What in the hell difference does it make what the UN Secretary-General thinks about anything?

    Don't you know how many years of insensive training it requires to become a secretary?

    oh wait... none? wow...

    Last time I checked the UN Secretary General was more important than your stupid-ass.

    If you're gonna dispute the article, then come up with some real reasons to dispute it besides this pathetic attempt at character assassination.

    Re: CO2 causing seas to turn to acid

    Humans add less than 1% of the gasses to the environment. It's ridiculous to think that reducing emissions will have ANY effect on the environment. 0.6 degrees in 50 years...oh yea, BIG changes...i love how people claim - THIS IS THE HOTTEST SUMMER / COLDEST WINTER EVER. They are so short sighted, it's ridiculous. EVERY year can't be the hottest year...and when you look at almanac data you will see it's NEVER TRUE.

    Who's assassinating his character? I was just asking "who cares?".
    Here are his qualifications:
    BAN KI-MOON
    Education-- Mr. Ban(They put their last name's first, over there. They're a bit backwards from the start.) received a bachelor's degree in international relations from Seoul National University in 1970. In1985, he earned a master's degree in public administration from the Kennedy School of Government at Harvard University.
    He's a bureaucrat!
    OK, now I'm assassinating his character.:whip: Are you happy?
