Opinion of honor in favor of sulfur emission

For the problem of global warming, numerous solutions have been proposed, some of which have been considered reasonable and others have been ruled out. Paul Crutz's Nobel Prize winner wanted to recover one of the latter for scientists to review: the emission of sulfur to the stratosphere.
The sulfur of the stratosphere reflects the radiation from the Sun to space, so it does not reach the troposphere or the earth's surface and the Sun warms the Earth less. This process occurs naturally, as large volcanic eruptions release sulfur to the stratosphere and cause a cooling, as is the case with the eruption of Mount Pinatubo in 1991, which reduced the temperature of the planet by half degree. Likewise, man himself could release sulfur into the stratosphere to artificially obtain a cooling effect.
He has defended this idea of Crutz, but has not hidden at all the disadvantages of the method. On the one hand, it would affect the environment, as it would affect the ozone layer and eventually cause acid rain, not forgetting that Crutzen received the Nobel Prize in Chemistry for ozone layer research. On the other hand, it would be a very expensive method, as it would require the repeated release of sulfur to the stratosphere. According to Crutzen, more than 5 million tons of sulfur should be released.
This large amount of sulfur cannot be poured at this time, it is a long-term proposal. In addition, the details of the process are not known, so Crutzen asks not to be rejected. According to him, the subject needs a lot of research, but once done this will have to decide if the method is valid and worth it.
