    ...are reassessing, huh?

    This, from the U.K. Telegraph:


    UN downgrades man's impact on the climate

    Richard Gray, Science Correspondent, Sunday Telegraph


    Mankind has had less effect on global warming than previously supposed, a United Nations report on climate change will claim next year.

    The UN Intergovernmental Panel on Climate Change says there can be little doubt that humans are responsible for warming the planet, but the organisation has reduced its overall estimate of this effect by 25 per cent.

    In a final draft of its fourth assessment report, to be published in February, the panel reports that the level of carbon dioxide in the atmosphere has accelerated in the past five years. It also predicts that temperatures will rise by up to 4.5 C during the next 100 years, bringing more frequent heat waves and storms.

    Climate change sceptics are expected to seize on the revised figures as evidence that action to combat global warming is less urgent.

    Scientists insist that the lower estimates for sea levels and the human impact on global warming are simply a refinement due to better data on how climate works rather than a reduction in the risk posed by global warming.

    One leading UK climate scientist, who asked not to be named due to the sensitivity surrounding the report before it is published, said: "The bottom line is that the climate is still warming while our greenhouse gas emissions have accelerated, so we are storing up problems for ourselves in the future."

    The IPCC report, seen by The Sunday Telegraph, has been handed to the Government for review before publication.

    It warns that carbon dioxide emissions have risen during the past five years by three per cent, well above the 0.4 per cent a year average of the previous two decades. The authors also state that the climate is almost certain to warm by at least 1.5 C during the next 100 years.

    Such a rise would be enough to take average summer temperatures in Britain to those seen during the 2003 heatwave, when August temperatures reached a record-breaking 38 C. Unseasonable warmth this year has left many Alpine resorts without snow by the time the ski season started.

    Britain can expect more storms of similar ferocity to those that wreaked havoc across the country last week, even bringing a tornado to north-west London.

    The IPCC has been forced to halve its predictions for sea-level rise by 2100, one of the key threats from climate change. It says improved data have reduced the upper estimate from 34 in to 17 in.

    It also says that the overall human effect on global warming since the industrial revolution is less than had been thought, due to the unexpected levels of cooling caused by aerosol sprays, which reflect heat from the sun.

    Large amounts of heat have been absorbed by the oceans, masking the warming effect.

    Prof Rick Battarbee, the director of the Environmental Change Research Centre at University College London, warned these masking effects had helped to delay global warming but would lead to larger changes in the future.

    He said: "The oceans have been acting like giant storage heaters by trapping heat and carbon dioxide. They might be bit of a time-bomb as they have been masking the real effects of the carbon dioxide we have been releasing into the atmosphere.

    "People are very worried about what will happen in 2030 to 2050, as we think that at that point the oceans will no longer be able to absorb the carbon dioxide being emitted. It will be a tipping point and that is why it is now critical to act to counter any acceleration that will occur when this happens."

    The report paints a bleak picture for future generations unless greenhouse gas emissions are reduced. It predicts that the climate will warm by 0.2 C a decade for the next two decades if emissions continue at current levels.

    The report states that snow cover in mountainous regions will contract and permafrost in polar regions will decline.

    However, Julian Morris, executive director of the International Policy Network, urged governments to be cautious. "There needs to be better data before billions of pounds are spent on policy measures that may have little impact," he said.

    Oh, and here's something else...the link for the entire summary follows:

    Livestock’s long shadow
    Environmental issues and options


    By H. Steinfeld, P. Gerber, T. Wassenaar, V. Castel, M. Rosales, C. de Haan - 2006, 390 pp

    Summary: This report aims to assess the full impact of the livestock sector on environmental problems, along with potential technical and policy approaches to mitigation.

    The assessment is based on the most recent and complete data available, taking into account direct impacts, along with the impacts of feed crop agriculture required for livestock production.

    The livestock sector emerges as one of the top two or three most significant contributors to the most serious environmental problems, at every scale from local to global.

    The findings of this report suggest that it should be a major policy focus when dealing with problems of land degradation, climate change and air pollution, water shortage and water pollution, and loss of biodiversity.

    Livestock’s contribution to environmental problems is on a massive scale and its potential contribution to their solution is equally large.

    The impact is so significant that it needs to be addressed with urgency. Major reductions in impact could be achieved at reasonable cost.

    The panel, however, has lowered predictions of how much sea levels will rise in comparison with its last report in 2001.

    Two strategies are suggested by these reports:

    1. Eat beef at every meal in the hope we will make cows extinct.

    2. Spend more money to acquire "better data", as better data has proven most effective in mitigating the "doom" content in doomsday forecasting relative to global warming.

    You know it makes sense.

    Yep I agree.

    Just thought, we're eating too much and endangering fish, yet giving them more room to swim around and reproduce in. Sigh.

    Furthermore, anyway... During that research, they can get people to skateboard, show them how fun it is and that more. Then place more Wind Turbines out in the sea, ironically of which theres more area to choose and place them in now, and more than just a few else it's pointless. That way protesters that they're not doing enough (kinda true though) can't complain.

    Finally, invest more sensibly into researching at the same time as the data, Quick, Cheap, and Affordable alternative fuel to deal with the current problems. Actually, kind of off topic now I guess, but I heard randomly the other day there's a blood protein in, us, that could be used to produce hydrogen. Weird.

    Exactly, and a million reasons to do it, even apart from environmental concerns.

    Now.

    Another cut and paste job j2?

    What do YOU think?

    We know you're an advocate of doing nothing, as your lords and masters the oil companies suggest, but what if? What if you're wrong? Are you gonna stand up and apologise to your grandchildren for doing nothing despite all the warnings?

    What people like you fail to mention is this, if we clean up our act and are subsequently proved wrong, we have lost NOTHING, if we fail to act, as you believe we should, and are proved wrong, we lose EVERYTHING.

    Here's a little cut and paste from your own cut and paste ...

    Scientists insist that the lower estimates for sea levels and the human impact on global warming are simply a refinement due to better data on how climate works rather than a reduction in the risk posed by global warming.

    the way i read it, it was saying it exists and it's bad, just not as bad as we previously thought.

    I read somewhere recently that it exists, and it's bad, and it's worse than we previously thought, because of solar dimming

    apparently it's like a balancing act and too far either way will cause major pwnage. that's what the telly said anyway.


    there's hundreds of theories, but the "liberals trying to undermine the iraq war effort" seems the most rediculous

    We are out nothing except time, resources, energy and whatnot that could have been applied to, oh I don't know, say world hunger, aids. You know, the little things.

    As if the money would be spent on that instead! Don't make me laugh


    Oh, controlling climate change will help with world hunger, btw

    Oh come on, talk sense man, tell your excuse for a president about world hunger and aids, because he spends enough money to combat those things every WEEK on wars.
