A radical new form of solar geoengineering.
As we all know, such crazy ideas wouldn't even be on the table if humans had drastically curbed their use of fossil fuels years ago — butWhile some scientists warn that geoengineering is a dangerous distraction from the true work needed to cut emissions, others say we need to assess all options. That's where the MIT team's space bubbles come in. of solar geoengineering
, which is designed to reflect sunlight away from Earth so as to cool our planet and prevent the worst effects of climate change. The most widely studied solar geoengineering technique involves injecting reflective aerosol particles into the upper atmosphere. However, the potential negative impact of such a method is not yet fully understood, meaning it is far from being seen as a viable option.
The MIT scientists' approach would be a little different. Instead of injecting particles into Earth's atmosphere, their approach would reflect the sun's heat from space, meaning no potentially harmful particles would have to be injected into our atmosphere. The researchers are studying the possibility of positioning a shield made of"space bubbles" at Lagrangian Point 1, which is a relatively stable orbital point in space, where the gravitational pull of Earth and the sun evens out. TheMIT's 'space bubble' solution could be deployed from space. Source: The biggest hurdle for this method is without a doubt in the logistics. The MIT scientists believe that the bubble shield would have to be roughly the size of Brazil.
