Unexplained Leap In CO2 Levels

Cally writes "The Guardian is reporting that atmospheric CO2 concentrations have leapt by 4.5 ppm in the last two years. This raises the ugly possibility that the capacity of a large carbon sink (possibly the oceans) has been exceeded, and the worst-case scenario is that a tipping point has been reached and a runaway warming scenario is in progress. Quote from Dr. Piers Foster of Reading University: 'If this is a rate change, of course it will be very significant. It will be of enormous concern, because it will imply that all our global warming predictions for the next hundred years or so will have to be redone.'"

    Peat Bogs outburn Western Europe New Scientist 18 Oct 1997


    PEAT bogs in Indonesia that have been set alight by the country's raging forest fires could release more carbon dioxide into the atmosphere over the next six months than all the power stations and car engines of Western Europe emit in a year. The finding backs up claims that the fires could have a significant impact on global warming.


    Sometimes there is very little that we can do to stop the production of CO2 into our atmosphere. Natural causes, like breathing put tonnes of CO2 into the air. Why haven't we begun a program using iron oxide spread on the ocean to trap and remove CO2? It's viability was proved years ago?. Why are environmentalist opposed to a scientific solution?

      Why are environmentalist opposed to a scientific solution?

      Is that a question or a statement? What makes you assume that environmentalists are opposed to scientific solutions per se?

      Do you not think that developing greener cars or greener ways of creating energy are 'scientific' solutions? Or using technology to reduce the CO2 emissions from existing power plants / factories? Or using more efficient light bulbs etc etc? Environmentalists seem to generally support these things, in addition to other methods. If they're against any 'scientific' solution (i.e. say nuclear energy or this idea of yours) its not due to it being scientific, rather (possibly overblown) concerns about side-effects it may have (i.e. nuclear waste).

      Also, the fact that there are unavoidable causes of CO2 doesn't mean we shouldn't avoid the avoidable - the earth exists in a balance (i.e. of CO2 sinks and sources), and its the very avoidable increases over the past few hundred years in our increase in CO2 that appear to be tipping the balance, not the occasional forest fire etc which have always occasionally happened.

    There is no question that human activity has resulted in increased carbon dioxide levels.

    Of course, we don't emit as much CO2 now as was done in the mid-12th century (aka "the Little Ice Age"); over a period of about 50 years, it got so cold that about 75% of the Black Forest was cut down, reducing it to smaller than its current size. All of that went up in smoke.

    And we don't emit as much in a year as a good size active volcano can do in a week. But we do emit enough to cause CO2 levels to rise.

    Of course, the link to changes in _climate_ from increased CO2 levels isn't really clear. Global warming is the common concern, but the opposite has just as much evidence, and there's even a lot to show that any effect either way will simply cause a negative feedback loop to stop it. Nobody really knows, because climate studies are a real bitch to figure out.

    Of the two, an iceage is probably more likely than warming, anyway; we're overdue for one, and the sun appears to be going into another contraction cycle (which means less heat coming in). And frankly, the Earth spends most of its time as a snowball; the nice weather we get these days is purely an aberation that will correct itself over time.

    I saw a story on (I think) PBS about this. A guy, many years ago (5-8 years) marked off some plots in various locations. Once a year he goes and samples the soil from these plots. His finding was that carbon (CO2) is being depleated from the soil. In turn, the the warming planet will increase the rate of CO2 release from the soil. IIRC, from his test plots, the carbon levels present in his plots were down something like 5x what they were when he started his experiment.

    His conclusion that the warming of the planet will greatly accelerate the release of carbon from the soil, which in turn, will warm the planet, which in turn will release more carbon from the soil. As you can see, he predicts a nasty spiral.

While human-created CO2 may well be causing global warming (if there is a warming trend), it might also be the natural warming trend that started at the end of the last ice age.

    We need to understand that climates change, always have and always will. We like our current climates, but they won't be here forever, even if we reduce the atmospheric CO2 levels.

    We know that humans have slightly increased CO2 levels in the atmosphere, but hard evidence linking that to temperature rises is minimal.

    You can't get lots of hard evidence until it's too late to avoid massive costs, financial and humanitarian. Demanding hard eveidence when the experiment more or less puts your existence at stake is meaningless. Informed estimates and simulations are all we have to go on.

    Industry uses risk analyses on analogous problems all the time, and even if the probability of the human-caused global warming scenario was very low (which it is not), the potential cost is unbelievably huge. If this was a company-internal issue, a standard risk analysis would flag it so red, no sane management would ignore it the way governments (even the ones who have signed up for kyoto) are now doing.

Sucessfull 'programs' always get dismantelt after a set goal is archieved. For the people that get paid for solving the problems this obviously generates a conflict of interest. The research budget for 2000 climate researchers in the US has been 2 billion$ in 2002. When do you think that the budget is increased? The need for generating a problem to justify ones income clearly biases scientists on government payroll. Or why else do you think that the 'industry' is mainly concerned with churning out solutions while the government immediatly jumps unto any scare-train that runs past?

Restricting the use of affordable energy sources in the draconian manner that computer models would require will bring about widespread un-civilitation: poverty, hunger, diseases etc. For all people already living on the verge of civilitation this will be certain death. The cost of kyoto alone run into the hundred billion range depending on the actual country. The $150 billion predicted for germany amount to be 5% of the GDP. This is a huge dent for the productivity of an economy and by extension for the wealth of its participants. The extra cost inflicted on industries can have only one consequence: The companies that are already producing 'on the margin' (meaning that any slight increase in costs will convert profits to losses) will have to move somewhere else (presumably somewhere where the kyoto protocol is not in effect) or go broke. The consequential stagnation of tax revenue coupled with the increase in entitlement to government aid (the unemployed) will futher diminish the states chances of implementing necessary wellfare reforms an thereby bringing it closer to the point of 'state-default' with all the really scary effects this can have (see germany in the 1930ies)

    Not everything is political. There is a consistent record of increasing concentrations of CO2 over time. This increase corresponds to an increase in the production of CO2 by humans (coal, oil, etc.); the predicted increase is twice the observed increase, possibly because the oceans have acted as CO2 sinks. The record on CO2 concentrations goes back about 800,000 years (also interesting). I assume that any reasonable person can accept this information (i.e. this is not political).

    The next question is what is the impact this increasing concentration of CO2 (and other "greenhouse" gasses) on the climate. No one has a completely correct answer. A variety of mathematical models have been used and the predictions of these models have been tested in various ways (e.g. comparison with existing recoreds). None of these models is perfect. However, the majority of scientists who study climate questions, using a variety of techniques, conclude that the increased concentration of greenhouse gasses has contributed and will contribute to a warming of the earth's atmosphere. No one knows exactly how great will be this increase and this is a subject of great interest.

    --don't let in ANY foreign vehicles which don't offer hybrid or Honda ULEV (ultra low emission vehicle) standards

    --don't let your nation have hundreds of thousands or millions of new drivers monthly taking to the roads in pollution-belching, smog-assisting vehicles.

If you face being starved by the US, it could force your hand and make you precipitate a war, war which no on needs

    --Lighter vehicles, particulary the non-allowance of SUVs, would allow your roads to last longer, requiring lest tar, asphalt, cement and other materials which also exude chemicals under harsh sunlight, and material which is worn off and sent into drains or into the air

    I rattled on with more details, but these are the salient points. Besides, if more cars are produced locally there, and are cleaner, less maritime/marine fuel would be used shipping all over the place.

    So, to me, it seems China WANTS to publicly, if not actually, do a nice part. We'll see, though, in a few years, based on satellite imagery.

    The time is NOW for automakers to get off their oil-shackled asses and start mass-producing hybrids and lower-horsepower vehicles so that economies of scale will forever shut down the squealing, lying-assed manufacturers garbage about "we're losing money on hybrids".

    First of all, they're outright lying to maintain their comfort zone.

    Second, they're being manipulated from within and without to dupe the public into not pressuring them as much.

    Third, NO, I repeat NO average citizen joe or jane deserves or has any RIGHT to drive a recklessly irresponsible, gas-swilling vehicle high-horsepower. Why should civilian vehicles (other than the weak argument of allowing citizenry to "blow off steam on occasion) have over 150 horsepower? WHY? Just to pass up somebody? Show off some status? Evade or speed away from a stalker? BS excuses, and poor, weak states of mind, I think.

    Horsepower, necessitated by heavier, show-off vehicles, and coupled with mindless demand for ever-increasing "POWER and SPEED" contribute to the production of major gulpers of fuel.

    The ONLY I repeat ONLY entities entitled to drive powerful vehicles should be:

    -law enforcement
    -heavy construction
    -product transportation
    -mass transit
    -fire, medical, and rescue teams
    -agriculture
    -SOME, but not all, individuals who demonstrate a need to be securely transported from point A to B

    and similar.

    Individuals who THINK they need a gas-swilling vehicle need to rethink their options, and change their habits. If they think this piece of my mind is an encroachment upon "their rights" then maybe THEY should play chicken in the road to earthmovers that can crush them; maybe THEY should be put into rooms hooked to CO2 and other exhaust by products; maybe THEY should have a greatly higher property tax or use tax on road-wearing, air-heating, intimidation-exuding vehicles.
