MIT suggests using ‘space bubbles’ to cool the Earth

While some scientists warn that geoengineering is a dangerous distraction from the real work needed to reduce emissions, others argue that all options need to be considered. This is where the MIT team’s space bubbles come in.

The Massachusetts Institute of Technology has proposed using “space bubbles” to cool the Earth. Find out what your thoughts are.

A team of MIT researchers is investigating the method of Combating the effects of climate changereveals a press release from Journalism. They suggest using "space bubbles" to reflect sunlight away from Earth. -

Safer form of solar geoengineering

The MIT team's method is a new form of solar geoengineering designed to reflect sunlight away from Earth in order to cool our planet and Preventing the worst effects of climate change.

The most studied solar geoengineering technique involves the injection of reflective aerosol particles into the upper atmosphere. However, the potential negative impact of such a method is not yet fully understood, which means that it is far from being considered a viable option.

The approach of the MIT scientists will be slightly different. Instead of injecting particles into the atmosphere, Your approach will reflect the sun's heat from spacewhich means that potentially harmful particles will not have to be injected into our atmosphere.

Researchers are studying the possibility of placing a shield made of "space bubbles" at Lagrange Point 1, a relatively stable orbital point in space where the gravity of the Earth and the Sun evaporate. The James Webb Space Telescope, for example, is at Lagrange Point 1.

The biggest obstacle to this method is, undoubtedly, the logistics. MIT scientists believe that the bubble shield should be so Almost the size of Brazil. However, they believe that bubbles can be manufactured in space, reducing launch costs. They are currently running experiments in the lab using "space bubbles" made of silicon.

In the initial experiments, we were able to inflate a thin film bubble to a pressure of 0.0028 atm, and keep it at around -50 °C (to approximate space conditions with zero pressure and near-zero temperature).

Investigators said in a press release.

Are space bubbles a savior of humanity?

Crucially, the MIT researchers also wrote that their solar geoengineering solution would be "completely reversible," which likely means that Bubbles can burst quickly If they find out that they have an undesirable effect on our planet.

This is very important, because we still do not fully understand the full complexity of climate change itself, let alone geoengineering methods.

Our understanding of climate change, which we are inadvertently causing at the moment, still has limitations, especially when it comes to more future impacts. Our understanding of what would happen if we purposely manipulated climate on a global scale is less than that.

Linda Schneider, an international expert on climate policy, said in an interview.

Of course, more research is needed, despite the fact that, on paper, "space bubbles" are a safer form of solar geoengineering. However, if, as expected, the worst effects of climate change become a reality, this proposal could be a lifesaver for humanity.
