Geoengineering Likely to Worsen Climate Change, Not Fight It


earthwrenchGeoengineering techniques have received quite a bit of attention over the past decade. One of the main reasons for this, is that they could potentially present a fast and very effective mean to prevent devastating climate change.

But, as it now turns out, this statement is nothing more than a claim, or an assumption, without a proof. Scientists from GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany, developed a 3D computer model, which shows that five of the most popular geoengineering techniques could actually make climate change worse, rather than the other way round.

The findings of the research appeared yesterday in the Journal Nature Communications and most definitely poked quite a number of people, who thought that there is a fast and easy solution to handling excessive carbon dioxide concentrations in the atmosphere. By running a relatively simple, or OK, not extremely complex earth system model, the authors were able to demonstrate that common geoengineering techniques are quite ineffective in a long run. In addition, the team demonstrated that actually there is a huge possibility that the effect is reversed and our “tweaking” of the environment might have severe consequences.

The five techniques that they tested are extremely common. These include afforestation, artificial ocean upwelling, ocean iron fertilization, ocean alkalinization and solar radiation management. We have told you about each one of them and some point or another, but here are some details related to the model outcome.

Afforestation, or the process through which deserts are turned into irrigated areas, would cause the newly planted trees to absorb incoming light and therefore prevent deserts from reflecting it back to space. Ocean upwelling, another one of the examined techniques, is the process where pipes pump cold water at great depth and deposit it on the surface. Initially, it was expected that this technique would encourage photosynthetic organisms to grow on the surface. However, in order to be effective, it has to be run continuously. If it is stopped, the oceans will return their balance, and climate change will be even more drastic.

Moving on to ocean alkalinization, where lime is deposited in the ocean to increase the carbon absorption abilities and ocean iron fertilization, which should stimulate the growth of photosynthetic organisms. Both techniques were found to be extremely ineffective in reducing temperatures. The last one, solar radiation management, where sulfate-based aerosols are pumped into the atmosphere so that incoming light is dimmed, supposingly causing cooling of the Earth. Here the researchers established that this will not prevent the accumulation of carbon dioxide, therefore if ever the particles disappear or the measure is stopped, the consequences would be devastating.

The conclusions are very clear. Even if all these techniques are applied continuously, the reduction in warming would be not more than 8%, while if stopped, climate change would accelerate. Bottom line is, there is no easy way out. We should keep trying to cut down emissions and forget about the magic trick that will bring everything back to the way it was.

  1. Worldwide Methane Reduction Project

    is researchinga geoengineering method of reducing anthropogenic methane gas emissions
    by an awesome 38% !

    to an NOAA report;  In 2007 methane rose by
    27 million tons after nearly a decade with little or no increase. NOAA
    scientists released these and other
    preliminary findings as part of an annual update to the NOAA annual
    greenhouse gas
    index, that agency’s greenhouse gas index,
    which tracks data from 60 sites around the world.”

    emissions- methane made by human activities
    such as raising livestock, rice cultivation, landfills, and methane
    escaping from
    coal mines and gas wells are a major cause of
    greenhouse warming. Methane captures 23 times as much solar heat as
    carbon dioxide.

    is seeking funding for our project that can
    make a bigger dent in the amount of greenhouse warming than all the wind
    farms and
    solar energy panels installed to date. If we
    put it into production worldwide, our research program is capable of
    a few more percentage points from the rate of
    greenhouse warming. 

    will be much easier and cheaper to reduce
    anthropogenic methane from the sources listed on this webpage. For say, a
    dollars we can reduce the total greenhouse
    effect dramatically;  A 38% methane reduction in anthropogenic methane
    emissions corresponds to 4.2% of all
    greenhouse warming. What else can you do with a billion dollars?
    Construct two giant
    CSP solar plants in the desert? The impact of
    those plants by themselves is minuscule. You would have to have a
    program of building solar energy plants and
    other renewables costing trillions to effect the same drop in global

    Vulvox is now soliciting donations and intern volunteers for jobs such as secretaries, sales development, product
    development, grant writers, publicity people,  etc and we are also seeking industrial and university research partners, promoters, and angel investors to help us with this very important project. 
    Contact us to apply.
