Looking at the current environmental conditions, no one is taking serious efforts to control CO2 emissions. So, researchers from Yale and Harvard have decided to overcome the problem from another side. The study is recently published in the journal Environmental Research Letters. According to the study by the researchers, the effects of global warming could be cut to half by dimming the Sun through spraying huge quantity of sulfate particles into the lower stratosphere of the Earth, which is also a cost-effective way.
On the basis of eagerness over such highly indefinite, theoretical, and determined plan, there is no surety that the plan will not turn present conditions worse in disastrous form. There is an incredulous lack of knowledge about the effects of fading the Sun on the people completely relying on it for basic needs– like agriculture or temperature maintenance.
Rather than understanding the consequences, the study considers the probable expenses and required technology to realize the determined plan. Different possible ways are discussed by the researchers to successfully complete the geoengineering project. The possible ways include balloons, airplane, or even simply gunfire chemicals in the sky using large guns
The plan proposal estimates an initial cost of nearly $3.5 Billion, for the commercial launch, and also an additional amount of $2.5 Billion for the long-term progression of the project of 15 Years. However, the launch of the project could be accomplished within 15 Years according to the proposal. The major significance of this huge-scale project is that it needs comparatively low funding for accomplishment.
The technical drawbacks for the project include the unavailability of aircraft at present that could be able to deliver a huge quantity of loads in the atmosphere. The non-technical drawback comprises the mandatory approval and global coordination among all the nations for the launch of the project.
