Unexplained Leap In CO2 Levels 1215
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.'"

This is exactly right. Those that say global warming doesn't exist, is living, 100% in a fantasy world. AFAIK, the only question is, is global warming part of a cyclical trend, directly caused by human efforts, or both?
There is certainly some trending which indicates that human's are part of the "cycle". The only question is, are human causing the trend to be above what the "normal" cycle would normally be.
Second, the theory is quite sound. CO2 pushes the energy budget of Earth up. Less energy out means Earth has to heat up.
I personally believe that humans are pushing the trend above the bell curve. Simple fact is, the theory is well supported by physics, as we understand it, and we are able to make observations which support our level of understanding. To me, the only question which remains, how far off the curve are we? And, will the departure be enough to matter in the long run? Those questions, IMO, are the really tough questions to answer. Frankly, I'm not sure we have the ability to answer it unless the environment makes a huge swing, for good or bad.

Thank you for reminding us about the cycle of photosynthesis, which among other effects gobs up CO2 and water, and produces sugar (for the plant to eat) and dioxygen as a byproduct.
Now what do you think they do with all this sugar ?
Now please hit Google and learn about the other part of the energy cycle present in most plants and indeed in most modern living organisms, which is called "respiration" (you may have heard about it): an oxidation process using dioxygen to degrade aforementioned sugars into ATP (nearly universal form of energy storage in living cells) and BLOODY CARBON DIOXIDE !
This page [wcsscience.com] summarises the main points in an intuitive way.
At any rate, the production of oxygen by trees is simply tiny. The massive release of oxygen in the atmosphere, arguably one of the most important events in the history of life, was caused by the first photosynthetisers, like cyanobacteria - bacteria that do use photosynthesis to produce sugar (and oxygen), but degrade this sugar through older, less efficient mechanisms such as fermentation. Of course they did not use respiration, because before they appeared there was no oxygen to breathe (duh !)
Besides causing havoc in the primitive fauna, the so-called "oxygen holocaust" led to the appearance of the much more efficient respiration mechanism. Which in turn allowed for the emergence of much more complex forms of life (Eukaryotes) in a Bacterial world.

One way to drastically drop the carbon level is to seed the southern Pacific ocean with small amounts of iron. This has been shown to cause an algae bloom, drastically increasing the sinking of CO2 from the air. (A major fraction of the algae die without being eaten and sink, taking the carbon with them to the deep ocean where it sits for millenia until the sluggish currents bring it to an upwelling.)
If we have a runaway we can try using this to turn it around. Attempting to fine-tune the carbon content of the atmosphere with it now risks the opposite spiral and a new ice age:
- Carbon sink lowers the C02 level and greenhouse effect.
- CO2 drop produces global cooling.
- Cooling results in more glaciation on Antarctica and the polar extremes of the other continents.
- Sequestered water and cooler temperatures reduce rainfall.
- Reduced rainfall expands deserts.
- Expanded deserts result in more dust in the atmosphere, including iron and other micronutrients.
- Some of this dust falls in the ocean, reenforcing and expanding the algae blooms.
There is currently some question as to whether this, rather than (just) solar cycles or continental drift modifying weather cycles, is the cause of ice ages.

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.

NEPI was dedicated to transforming both the EPA and the FDA, and challenging the cost of Superfund toxic cleanups by these large corporations.
NEPI was also associated with the AQSC (Air Quality Standards Coalition) which was devoted to emasculating Clean Air laws. This organisation took up the cry of "we need sound science" from the chemical industry as a way to counter claims of pollution -- and Milloy became involved in what became known as the "sound-science" movement. Its most effective ploy was to label science not beneficial to the large funding corporations as "junk" -- and Milloy was one of its most effective lobbyists because he wrote well, and used humour (PJ O'Rourke was another -- but better!)
He joined Philip Morris's specialist-science/PR company APCO & Associates in 1992, working behind the scenes on a business venture known as "Issues Watch". By this time, APCO had been taken over and become a part of the world-wide Grey Marketing organisation, and so Milloy was able to use the international organisation as a feed source for services to corporations who had international problems.
Issues Watch bulletins were only given out to paying customers, so Milloy started for APCO the "Junkscience.com" web site, which gave him an outlet to attack health and environmental activists, and scientists who published findings not supportive of his client's businesses. Like most good PR it mixes some good, general criticism of science and science-reporting, with some outright distorted and manipulative pieces.
The Junkscience web site was supposedly run by a pseudo-grassroots organisation called TASSC (The Advancement for Sound Science Coalition), which initially paid ex-Governor Curruthers of New Mexico as a front. Milloy actually ran it from the back-room, and issued the press releases. Then when Curruthers resigned, Milloy started to call himself "Director" (Bonner Cohen - another of the same ilk also working for APCO - became "President")
Initially all of this was funded by Philip Morris, as part of their contributions to the distortion of tobacco science, but later they widened out the focus and introduced even more funding by establishing a coalition -- with energy, pharmaceutical, chemical companies. TASSC's funders include 3M, Amoco, Chevron, Dow Chemical, Exxon, General Motors, Lawrence Livermore National Laboratory, Lorillard Tobacco, Louisiana Chemical Association,National Pest Control Association, Occidental Petroleum, Philip Morris Companies, Procter & Gamble, Santa Fe Pacific Gold, and W.R. Grace, the asbestos and pesticide manufacturers.
TASSC was then exposed publicly as a fraud. And so Milloy established the "Citizens for the Integrity of Science" to take over the running of the Junkscience.com web site.
