is, er, not working. There is only so much that technology can do, and arresting climate change is not one of them, claims a research.
This comes as a spanner in the works of those working night and day to evolve policies and mechanisms to arrest climate change. The implementation of climate engineering technologies as a last ditch effort to combat the escalating effects of climate change could, in fact, make things worse, assert a team of researchers.

According to a modelling study published in Nature Communications recently, climate engineering is likely to be either relatively ineffective or might even result in severe climatic side effects.

With the rate of climate change itself far outpacing mitigation strategies, climate engineering as a potential means of preventing catastrophic climate change has been attracting considerable interest from both climatologists as well as governments. Climate engineering, also known as geoengineering, refers to manmade technologies specifically designed to manipulate global climate. While the potential effectiveness of individual methods has been tested, there have been few attempts to compare them.

David Keller of the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany, and colleagues used an Earth system model to evaluate the effectiveness and potential negative side-effects of five climate engineering technologies when deployed continuously, and at scales as large as currently deemed possible, under a high CO2-emission scenario.

There was a reason why the team undertook this study. They wrote, ìA previous comparison of the radiative forcing potential of different climate engineering methods addressed the question of how efficient the methods are at preventing global warming. However, the analytical methodology that was used did not allow for the quantification of side effects and the possible feedbacks in the climate system that may cause a method to be more or less effective than predicted.î In other words, there was a need to quantify the side-effects.

Technology just canít do it
The team has shown that, even when several technologies are combined, climate engineering would be unable to prevent mean surface temperatures from rising well above 2∞ C by the year 2100. In addition, they have projected that all technologies are, individually, either relatively ineffective with limited warming reductions (less than 8 per cent), or that they have potentially severe side-effects and cannot be stopped without returning large amounts of stored CO2 to the atmosphere and causing rapid climate change.

The teamsí findings strongly suggest that climate engineering technologies should not be depended upon to prevent future warming and that CO2 mitigation is likely the most effective way to prevent further climate change.

Caution needed
The researchers concluded with a word of caution, ìClimate engineering does not appear to be an alternative option, although it could possibly be used to compliment mitigation. However, if climate engineering is seriously considered as one of the means of preventing climate change, care must be taken when evaluating whether the potential reductions in atmospheric carbon and temperature of a particular method are worth the risks and costs of its side effects.î

  1. Well…they know that already, for the same reasons they know CO2 is not the cause of climate change in the first place. But there are two reasons why they wont stop.
    i) It’s a gravy-train. Climate scientists and related industries make lots of money (often paid for by our carbon-taxes) by studying, promoting and inventing rectifying-technologies. Their not about to say it doesn’t exist or there’s nothing they can do about it. Imagine a guy who gets paid very a good salary to clear sand from in front of the pyramids that has dropped from the soles of tourists shoes. He’s not about to say it’s not their fault and that all his sweeping makes no difference is he? That’s how he feeds his family.
    ii) TPTB need to use APGW and climate change to divert peoples attention from all the real and really bad shit they are doing to the world. Also, it allows them to do all sorts of nefarious experiments under the guise of combating CO2.

    Here is a rap I made about this very subject a couple of years ago.
