Carbon Dioxide Emissions Fall Worldwide In 2009

Hugh Pickens writes "The Christian Science Monitor reports that the good news is that emissions from burning coal, oil, and natural gas fell 1.3 percent compared with emissions in 2008 primarily because of the global economic downturn and an increase in carbon-dioxide uptake by the oceans and by plants on land. One big factor was La Niña, a natural seesaw shift in climate that takes place across the tropical Pacific every three to seven years, where the climate is cooler and wetter over large regions of land in the tropics, encouraging plant growth in tropical forests. However the bad news is that even with the decrease in emissions the overall concentration of CO2 rose from 385 ppm in 2008 to 387 ppm in 2009, as concentrations continue to rise even as emissions slip because even at the reduced pace, humans are pumping CO2 into the atmosphere faster than natural processes can scrub the gas. Many countries have agreed in principle to try to stabilize emissions at 350 ppm by century's end, which would result in a 50 percent chance of holding the increase in global average temperatures to about 2 degrees C over pre-industrial levels."

    Of course my argument is completely bogus - that was the point. The "(No, I'm not being serious)" was to indicate that I was aware of all the problems you mentioned, and was making an attempt at satirizing exactly the stupidity you describe.

    >>>not many people are down for spending the money to invest

    Not quite true. The U.S. Government spent almost a billion dollars to fund a solar panel factory in California. Unfortunately it went bankrupt because the chinese undersold them. Likewise the outlawing of incandescent bulbs (soon) resulted in the factory closing here, and the new CFL factory opening in china.

    If we are moving towards a green economy, it will be China/India and other cheap labor areas that benefit. Meanwhile here at home the USG will throw-away a ton of money on solar and other factories that eventually die out. Yeah I know you probably think I'm being pessimistic.

    I prefer to use the word "realist" and "observant". I can SEE the powershift from America to Asia.

    >>>We need to lose about 3 billion people

    You've been unfairly marked troll.

    But if the US, EU, AU, and Asian communities enacted a 1 child per family policy like China has done, their respective populations would drop to 1/10th present levels by 2110. i.e. From ~3 billion to 300 million. That alone would solve our pollution problem, and yes it would be humane (no need to kill anybody).

  4. Stabilize emissions at 350 ppm? by bunratty · · Score: 3, Informative

    We can't "stabilize emissions at 350 ppm". We can stabilize the concentration of carbon dioxide in the atmosphere at 350 ppm by reducing carbon dioxide emissions by 85%. We can do this by a combination of obtaining energy from sources other than fossil fuels (nuclear, solar, wind, biofuels, geothermal, etc.) and using the energy more efficiently (CFL and LED lighting, increased insulation, hybrid vehicles, etc.).

    Emissions were reduced due to economic decline.
    Atmospheric levels were reduced due to a climate cycle that increased absorption.
    Atmospheric levels actually increased due to increased emissions.

    So emissions went down and up, and levels went down and up. All in the same year.

    Science. We could use some here.

    I see why you are getting confused. The climate is a complicated system. There isn't just one mechanism controlling the global temperature. The one you always hear about in the news is CO2 (which is a complicated system of its own), but as you have learned here today, there are other factors like the variations in the sun's output and La Niña & El Niño. El Niño was the reason that 1998 was so hot (which is why if anyone tries to use that year to argue either for or against climate change then you know that they are being deliberately misleading).

    To explain how CO2 emissions can go down and yet the temperature can go up (ignoring the other factors), imagine that you have a bath filled with water. If you pull the plug then the water level drops. But if you turn on the tap to pour in the same amount of water that is going down the drain, then the water level will remain steady. It is not that the water stops going down the drain, but that the lost water is being replaced. This represents the CO2 levels in the atmosphere.

    CO2 is absorbed out of the atmosphere by various means, and more is emitted into the atmosphere from various sources - some of which are man made.

    Back to the bath, what happens if you turn up the tap so that more water is going into the bath than can go down the plug hole? The water level rises. If you put in an extra 5% of water then the level will increase by that amount because it simply has nowhere else to go.

    So does the water level go down if you reduce the water emissions by 1.3%? No, because you are still adding in 3.7% more water than the equilibrium. That is why your quoted text said "even at the reduced pace, humans are pumping CO2 into the atmosphere faster than natural processes can scrub the gas".

    That quote is a bit misleading, because as I said before there are many sources of CO2, so it is not just the amount pumped out by humans that is causing the problem. Some people have tried to use this fact as a reason for not doing anything about global warming, saying that it is not man's fault. It is a dubious argument, and in the end a pointless one. If we want to control the environment then the easiest solution is to adjust the portion of CO2 that is generated by man.
