In the realm of climate science, there are two approaches to dealing with climate change- adaptation or mitigation. Adaptation argues that humans will have to adapt to the new warmer, more extreme climate in order to survive.
Mitigation is the most common, and it “refers to efforts to reduce or prevent emission of greenhouse gases. Mitigation can mean using new technologies and renewable energies, making older equipment more energy efficient, or changing management practices or consumer behavior. It can be as complex as a plan for a new city, or as a simple as improvements to a cook stove design. Efforts underway around the world range from high-tech subway systems to bicycling paths and walkways”.
A new field of study that has been gaining momentum is geoengineering. Geoengineering is “the deliberate large-scale intervention in the Earth’s natural systems to counteract climate change”. Essentially, it is the idea that we can develop a technological solution to climate change that does not involve a change to human behavior. Admittedly, that is one the largest obstacles to taking meaningful action on climate change. It is very difficult to change human behavior on an individual level, much less on a global scale. Proponents of geoengineering suggest that while reduction of greenhouse gases is necessary, it will not be sufficient to prevent the dire effects of climate change. Therefore, they propose additional measures in terms of direct intervention to be coupled with more traditional mitigation tactics. Below is an image of some of the proposed geoengineering solutions.
However, there are understandable concerns when it comes to geoengineering, particularly in the area of unintended consequences. Is it really wise to deliberately alter the environment in some way? The ecosystem is such a complex, interdependent system, and altering one aspect may send the whole system into chaos. The argument could also be made that we are already indirectly undertaking geoengineering by contributing to climate change in the first place.
What do you think? Do you think that geoengineering is the solution that we have been waiting for, or do you think that it is too risky? Leave a comment below!
