Greenhouse Emissions Drop Less During Economic Downturn Than Expected 87

An anonymous reader writes with a quick bite from Nature World News: "The contribution of economic decline in reducing greenhouse gas emissions is very low, reveals a new study. Researcher Richard York of the University of Oregon studied data collected between 1960 and 2008 from more than 150 nations in order to analyze the impact of economic decline on greenhouse gas emissions." From the paper: "In Model 2, the percentage of the population living in urban areas and the percentage of GDP from the manufacturing sector were included as control variables. This model has lower data coverage than Model 1 (154 versus 160 nations, and 4,134 versus 5,630 nation-year observations) owing to missing data on the control variables. The coefficients, at 0.752 for growth and 0.346 for decline, are similar to those from Model 1 and, as in Model 1, are both significantly different from 0 and significantly different from each other."

      My guess is, that the effects of the recent economic downturn has yet to be realised - it's been kicked down the road by the creation of trillions of dollars and increased debt to offset its effect - it's been absorbed (hidden) by more debt and inflation.

      So I think it's a little too early to be making any judgements or conclusions.

    This is not really surprising.

    Apart from people generally not changing their habits during a recession, there is the fact that the recession itself didn't hit all countries with the same intensity. Some (e.g. China, India and South Korea) are still doing well, and as a consequence, their greenhouse emissions haven''t decreased much.

    While the developed countries did diminish their total emissions (e,g, UK, Japan, US, Germany), there is still the fact that the manufacturing sector ha been mostly transferred (outsourced or lost to) to the developing markets.Not surprising that the overall emissions have not dropped, at least in the same proportions that it increased during economic expansion.

      Rate presumably = speed of change.

      Thus the emissions dropped more quickly than when they had risen originally.

        It's "rate of release" vs. "rate of reductions in carbon dioxide emissions." Translates to "rate of release" vs. "rate of reductions of release." The second is the first derivative of the first which is not a valid comparison.

      I agree: The only way to definitely prove that AGW causes the Earth to burn to a crisp is to actually burn the planet to a crisp via greenhouse gas emissions, with no other variables that could affect the result. With an identical control Earth except for the CO2 and methane emissions, so we know that we have isolated the right variable. And double-blinded, so the researchers' biases don't creep in. And then repeat the test under the same conditions, so we know it wasn't just a fluke.

      Do you have some spare planets I can use for this test? In the meantime, I'm going to accept the correlation combined with the lab-tested mechanism for one variable of that correlation causing the other variable as the best we can muster.

        Your comment is Off Topic. This discussion is about rates of CO2 emissions. It is not about AGW or AGW models.

    • This is actually the important implication of this paper: emissions go up during a boom but fall less than they went up during a following slump. The author postulates that booms bring more infrastructure that remains in use subsequently.

    • by geekoid ( 135745 )

      "correlation is not causation."
      WRONG, DUMB ASS.

      correlation does not imply causation.

  • My theory is that between all the hot CO2 coming out of the economists, plus the off-gassing of freshly printed money, greenhouse gases are expected to increase during a downturn.

  • Americans are so obsessed with the idea that cutting down CO2 emissions would also cut down the economy.

    That is basically a brain dead idea.

    Lets see where CO2 is coming from:
    o heating of houses (coal/gas/oil)
    o heating and cooling of houses (electricity)
    o cars / trucks
    o power plants (coal/gas/oil)
    o cargo ships / diesel trains
    o and everything that uses electricity, but the prime source is the plant where that electricity is produced
    o industries with a huge energy hunger like steel plants / or any other factory that partly or in whole produces its own power (glass or porcelain producers, brick producers etc.)

    Now we have to look what kind of industries or businesses are effected in an economic crisis and how much that does affect the energy consumed.

    Do houses need less heating or cooling? Or do people change their cooling/heating habits during a crisis? Is there a significant different amount of homeless people during a crisis (wich don't power their own flat)?

    Same for cars, commuting, trucks with goods etc. etc. etc.

    I would say there is only a small group of industries that is affected by the crisis (look whose shares are dropping and whose are rising). And even if a factory is laying off 10% of its staff, I doubt it is directly reflected in 10% energy savings and CO2 reduction.

    As far as I know the american economy is far over 70% based on services. So only the remaining 30% are industries and manufactoring etc. To reduce CO2 emissions by 15% you would need an effect/crisis that drops the 30% above significantly. I doubt a change in services (people employed, people buying a service etc.) has any noticeable effect on CO2 emissions.

    And finally: no one is asking the USA to cripple their economy. We only ask to switch to more efficient machines, better insulation, more efficient means of transportation, burn less oil and build up a better grid. All those activities would create a lot of jobs and instead of having a crisis you would have a boom.

      Well, Fox news* has only fear to use as an AGW denialist organization. SO, you know point and claim it will cost jobs. Ignore that the best ways to deal with it involve getting industry here. It does hurt whomever wants to sell energy to China.

  • People need to get to work and people tend to drop things like air conditioning and most energy usage after going out to eat and new appliances vehicles etc. The overall effect is that what people tend to cut first during a recession are large purchases, like a new refrigerator/washer/dryer/car that would have been more efficient than the one they're now keeping. The old vehicles/appliances continue to put out a higher amount of CO2 and there is a noticeable delay in the decline of production after demand
  • In other news, US energy-related CO2 emissions are now at a 20 year low [aei-ideas.org].

    The credit is split between cheap, fracked natural gas replacing coal and herbicide-resistant GM crops needing less plowing (and thus lower tractor fuel use).

    US CO2 emissions per capita are now lower than they have been since at least 1973.

  • Coal has remained cheaper during most of this period, and half of all US energy use is for heating and cooling buildings, with little incentive to get new high mpg cars, since people can't afford new cars.

    Here endeth the lesson.

The best defense against logic is ignorance.
