A group of scientists has come up with a plan to fight global warming that does not involve reducing our emissions or being environmentally friendly. This plan consists of attenuating the sun by pouring sulphates into the lower stratosphere. What could go wrong?
The study, recently published, examines the ability and costs of various smoothing methods to bring sulfates into the atmosphere. This material would be introduced into the atmosphere at an altitude of 20 km above the ground. Researchers believe they could halve the increase in anthropogenic radiative forcing, as the project can be rolled out in 15 years.
The cost of the Matrix-type sun block would be about $ 1,500 per tonne of deployed equipment, with an average cost of $ 2.25 billion per year over the first 15 years of deployment. A big problem in this plan right now is that no existing aircraft can deploy the material into the atmosphere.
Scientists have concluded that a new tanker specifically designed for high altitude, with "substantial payload capacity," would not be prohibitive or too difficult to design and build. It would take about 4,000 flights a year to deploy enough sulphates into the stratosphere.
Scientists estimate that the required flights would increase linearly each year by about 4,000 flights. According to scientists, the high number of flights and large planes would prevent the program from running.
As you can imagine, not everyone agrees with this plan. Researchers have been talking about the reduction of global temperatures, but there is no clear indication that decreasing sun temperatures could affect life on Earth. In addition to tankers, researchers have also considered the use of balloons and large guns to project chemicals in the air.
