Over the past 50 or 60 years, global warming and climate change have brought significant changes to our lives. Global warming can be defined as the increase in average global temperature, on the other hand, climate change is accepted as the result of global warming, including droughts, heat waves, extreme weather events, etc. Yet there remains some disagreement as to whether geoengineering is a solution to counteract the harmful effects of global warming and climate change. It is claimed that geoengineering is complex and controversial, besides, requires negotiation and cooperation among governments, scientists, civil society, and the private sector. However, most people believe that geoengineering is the best solution to counteract the negative effects of global warming. Geoengineering is defined as the deliberate large-scale manipulation of an environmental process that affects the earth’s climate, in an attempt to counteract the effects of global warming.
To solve this situation, we begin by a closer look at the details of geoengineering. Geoengineering can be divided into broad categories: Carbon Dioxide Removal(CDR) and Solar Radiation Management(SRM). CDR consists of several interwoven terms and methods such as CO2 air capture, Afforestation/Reforestation, Ocean fertilization, avoiding deforestation, algae-coated buildings, and biochar. On the other hand, SRM includes several terms and steps like in the case of stratospheric aerosols, solar reflectors in space, enhanced surface brightness, roads-rooves-pavements, enhanced cloud brightness, and planting light-leaf species.
In the first place, one point which is believed to be absolutely pivotal is the fact that geoengineering should be implemented to reduce global warming immediately because the world is warming, this much people know and how much it will warm in the following decades. There is a wide discussion in many parts of the world today as to this issue because it is an undeniable fact that global warming affects several factors adversely in the four corners of the world. It is obvious that global warming has done a lot of damage to; but not for people. That’s why techniques of geoengineering are not only good for people but also good for the animal kingdom due to the direct impact on nature for example. In addition, it is important to emphasize that geoengineering is affordable and fast-acting and it requires less cooperation and altruism.
When it comes to the second point, at the heart of the matter lies another contributing factor: geoengineering should be implemented to prevent a potential humanitarian crisis and due to human rights. It should not be forgotten that people have some rights such as the right to land, the right to self-determination, the right to life, and the right to a safe and healthy environment. If the harmful effects of global warming continue to increase, the environmental side effects will be irreversible and people will not be able to find land and nutrition for eating. That is to say, they will not be able to fulfill their needs. Some African countries can be shown as the best instance of this, due to the fact that they suffer from droughts, starvation, lack of security and infectious diseases. In addition, due to these negative effects and insufficiencies, people will face a potential humanitarian crisis in the four corners of the world. According to research carried out by elite universities and scientists, Small Island Developing States(SIDS) will be seen in the coming decades like in Bangladesh. It is not wrong to say that it is not possible to live because of the population density of SIDS. As a result of this, it is an undeniable fact that people will face a humanitarian crisis.
On the other hand, some people claim that geoengineering is complex and controversial, besides, requires negotiation and cooperation among governments, scientists, civil society, and the private sector. However, these claims are not acceptable because it is important to emphasize that the negative effects of global warming are expected to intensify in the following decade and the detrimental effects will affect the entire world. Therefore, people have to take precautions to prevent these negative effects of global warming and implement techniques of geoengineering.
All that has been said raises the issue of whether geoengineering is a solution to counteract the negative effects of global warming. Although some people claim that geoengineering is complex and controversial and has different requirements, it seems that geoengineering is the best solution to prevent the negative effects of global warming. Otherwise, these detrimental impacts are expected to intensify in the following decade. No matter what happens, nothing is more important than human life, so it should be given due importance and it should not be endangered. Geoengineering is an intervention in nature in some sense but it has a role to play in shaping the future and society. Nature is an indispensable factor for humanity due to the fact that as can be seen above, it is related to everything in the world.
