Many scientists feel that application of Geoengineering would not reduce the amount of greenhouse gases in the air.
Explanation:
Geoengineering or climate engineering includes a wide range of technological applications that are aimed to counter climate change and global warming.
These include solar geoengineering for blocking the sunlight before it warms the earth’s surface, ocean fertilization, artificial trees etc. The main drawback that scientists fear is the usage of various chemicals because of which these technologies would not reduce greenhouse gas.
Further imposing tax regulations or simply signing climate protocols would not reduce greenhouse gases. They are just for gaining emission incentives and people will easily evade regulations.
The main focus should be on cutting down anthropogenic emission of greenhouse gases. Hence all the industries, technologies, and the people must pledge work towards reducing the greenhouse gases
