Reducing Sunlight With The Installation Of A Network Of Giant Solar Reflectors Essay

The proposals of reducing sunlight with the installation of a network of giant solar reflectors in space, and the artificial generation of sulfate aerosols in the stratosphere are ideas that we may have to consider in a nearer future than some may think. The latter approach, which could be achieved by burning sulfur or hydrogen sulfide in the stratosphere, would be a lot like a volcanic eruption such as that of Pinatubo in 1991, the difference being that the geoengineering aim would require the equivalent of a Pinatubo every four years or so (Oppenheimer 2011). Although it does not help as far as CO2 is concerned, but it can alleviate the problem while the long-term CO2 removal plans are being employed. There was a project called SPICE (Stratospheric Particle Injection for Climate Engineering) who had a team from the UK, with University of Bristol, the University of Cambridge, the University of Oxford and the University of Edinburgh collaborating.
The project focused on three steps; 1) evaluating candidate particles, which aims to understand the ways in which light and heat radiation interacts with the aerosol particles. 2) Then the delivery system; how will we inject the particles into the stratosphere safely, and 3) climate and environmental modeling, which would show what would happen to the climate if they were to use the chosen particle and delivery method (SPICE 2016). The project focused on finding particles that are highly reflective to sunlight, not too absorptive
