To geoengineer, or to not geoengineer; that is the question. There are many pros and cons to possible solutions to climate change involving geoengineering. The real question is: do the pros outweigh the possible risks? I personally do not think that we should rely so heavily on the possibilities of geoengineering being successful.
I believe that the risks far exceed the possible success. The fact that the plans for fixing the environment could majorly backfire and cause even more damage than was already there originally is too big of a consequence to think about utilizing geoengineering techniques to prevent the destruction of our ecosystem. Geophysicist Raymond Pierrehumbert discloses that if, for example, sulfur aerosols were chosen to be the method of choice for reversing climate change, they “would cool the planet, but we’d risk calamity the moment we stopped pumping: the aerosols would rain down and years’ worth of accumulated carbon would make temperatures surge” (https://www.theatlantic.com/magazine/archive/2009/07/re-engineering-the-earth/307552/) which would cause more harm than good and be worse for the planet than what it is currently suffering from today.
Not to mention the fact that the nations would have to find a way to split the cost if the solution is to impact the entire planet, not just one country, or one continent. Although geoengineering solutions are cheap and affordable by a singular country, I feel that it is important that everyone share the cost if the method of choice is capable of affecting the whole world. This raises more questions: how should the cost be distributed? Should the region with the most blame for climate crisis pay for it? Should everyone pay the same amount? Should countries with a higher carbon footprint in relation to everyone else have to pay more than those with a smaller carbon footprint?
In all honesty, I feel as though geoengineering should be a last resort. The possible negative side effects should serve as motivation for people to find better solutions with the technology we have currently at our disposal. However, if awareness is not brought to those who support geoengineering as a primary method of fixing the destruction of the environment, then they will be less inspired to help the planet now and increase the risk for increased climate crisis.
