According to a report submitted to United States Congressthe White House had expressed a cautious stance regarding the investigation of potential effects associated with Modified solar radiation (MRS) As a measure to counter global warming, I mentioned Politician.
the Solar geoengineering It is suggested to use Mrs To reflect more of the sunlight that hits the Earth back into space, through various techniques involving changes in the chemical composition of the atmosphere. It is said that this could contribute to global temperature reduction.
The report describes three strategies considered viable for implementing this controversial procedure. The first involves injecting aerosols into the stratosphere to increase the number of reflective particles and thus reflect more sunlight back out. This process occurs naturally after large volcanic eruptions.
The following strategy is based on The brightness of the sea clouds intensified Through aerosols in the lower part of the atmosphere, which increases its ability to reflect sunlight. Finally, it is considered to soften cirrus clouds, consisting of ice crystals, by spraying them with aerosols to reduce their ability to retain heat.
They detail the effects of its implementation
The report’s authors are certain that this study will “contribute to our understanding of the underlying climate processes and impacts of human greenhouse gas emissions,” as well as an assessment Potential risks and benefits of MRS. Moreover, they point out that MRS could cool the planet significantly in just a few years.
However, scientists warn that its implementation is likely to lead to unknown side effects. the Fisher Scientific Company Recall that it is not yet known whether these aerosols can adversely affect chemical processes in the atmosphere.
The report also details associated risks With all of the methods of MRS, including possible effects on human health, Biodiversity and geopolitics. These measures could alter global weather patterns and lead to disruptions to the food supply, as well as sudden warming if implemented and then stopped.
Although management Joe Biden Open to considering the possibility of studying MRS, it is emphasized that there are currently no plans to “establish a comprehensive research program focused on solar radiation modulation”. Last January, about 60 experts from around the world warned about the potential dangers of initiatives to mitigate the effects of global warming, including mrsAnd called on the authorities to ban such projects.
