A press statement said that a team of researchers from the Massachusetts Institute of Technology
Such strange and insane ideas would not have been necessary if people suddenly cut their use of fossil fuels drastically years ago. But it didn't happen.
While some scientists warn that geoengineering is a distraction from stopping climate change, others are sure that everything should be tried. For example, giant space bubbles.
What is solar geoengineering?
Scientists from MIT have presented a new form of solargeoengineering to reflect sunlight from the earth. The goal is to cool the planet and prevent the effects of climate change. The very idea of solar geoengineering is not new - this is not the first time scientists have proposed protecting the planet from sunlight. Typically, this method involves the introduction of reflective aerosol particles into the upper atmosphere. However, such a radical method can negatively affect the planet, this issue has not yet been sufficiently studied. And, therefore, it is not considered as a viable option.
What do scientists propose?
The approach of MIT scientistsinstitute is based on a different idea. Instead of injecting particles into the Earth's atmosphere, they plan to reflect solar heat from space. And, therefore, potentially hazardous substances will not threaten the health of people and ecosystems as a whole.
Researchers are exploring the possibility of placing a shieldof "cosmic bubbles" at the Lagrange point 1. This is a relatively stable place in space where the gravitational pull of the Earth and the Sun equalizes. The James Webb Space Telescope, for example, is located at Lagrange Point 2.
There is a problem
The biggest problem is to deliver the shieldto the right place. Scientists believe that it should be about the size of Brazil. However, engineers believe shield bubbles could be made in space, which would reduce launch costs. Now engineers are experimenting in the laboratory with "space bubbles" made of silicon.
In a press release, they explained howIn preliminary experiments, they managed to inflate a thin-film bubble at a pressure of 0.0028 atmospheres and maintain it at a temperature of about -50 °C. The experiment is necessary to try to recreate the cosmic conditions of zero pressure and near zero temperature.
Will it help?
Researchers at MIT emphasize that theirthe solar geoengineering solution will be "fully reversible". Apparently, bubbles can quickly burst if it turns out that they negatively affect the planet. This is very important, because humanity has yet to fully understand the complexity of climate change itself, not to mention the methods of geoengineering.
In an interview with Discover Magazine, LindaSchneider, an international climate policy expert, noted that our understanding of unintended climate change is still very limited when it comes to future impacts. It is simply impossible to imagine what will happen if people deliberately intervene in such global processes now.
More research is needed, despitethat "space bubbles" on paper seem to be the safest form of solar geoengineering. However, if a climate catastrophe becomes a reality, the idea of scientists will save humanity.
