The question of how to reverse or at least block global warming is arguably the biggest problem humanity faces in the 21st century – and with rising sea levels, extreme temperatures and high temperatures. depletion of our coral reefs, finding the solution is more urgent.
However, a group of scientists may have studied it as part of his research on sulphate propulsion in the lower atmosphere to reduce the intensity of sunlight.
In a study published in the journal "Environmental Research Letters", they examined the tactics and costs of "stratospheric aerosol injections". This is not a trivial matter, because it would be necessary to launch the material about twenty kilometers in the lower atmosphere.
Scientists have estimated that this could halve the increase in anthropogenic radioactive forcing. In other words, it could significantly reduce the amount of solar radiation remaining in the Earth's atmosphere instead of being reflected in space due to human emissions of greenhouse gases.
Atmospheric changes
The researchers predict that it would cost about $ 2.25 billion a year and could be ready for deployment in 15 years. However, there is currently no aircraft capable of launching equipment at these high altitudes.
In addition, the study did not examine the potentially devastating effects that decreasing sun could have on other lives on Earth; For example, plants and other photosynthetic organisms may have difficulty surviving in a less sunny environment, which would have huge consequences for animals and insects up the food chain.
While it's hard to know if this type of technology would ever be adopted realistically, it's obvious that any environmental engineering needs to be approached with caution – after all, the environment essential to keeping life alive. Earth is as finely tuned as an expensive wristwatch. any change in this environment could have huge repercussions on the entire planet.
