Scientists are working on a plan to cool the Earth by blocking the sun

“We can show the world: Look, there’s a working solution, take it and scale it up.”

Giant umbrella

Scientists are exploring a wild idea to stop our planet from warming: sending up parachutes To space to prevent the sun’s heating methods.

They are ready to put the idea to the test. as The New York Times According to reports, a team led by physics professor at the Asher Space Research Institute and director of the Technion-Israel Institute of Technology, Yoram Rosen, claims to be ready to build a prototype.

But there’s one big problem: The shield would have to span an area of ​​about 1 million square miles, or roughly the size of Argentina.

Since this structure is too large to be launched into space on a single rocket, Rosen and his team propose a scheme in which a swarm of smaller shadows would be launched into space, where they would work together.

“We can show the world, ‘Look, there’s a workable solution, take it and scale it up to scale,'” Rosen said. now.

Cast shadow

The idea has technically been around for decades. Instead of completely blocking the Sun with a giant umbrella, researchers suggest that we only need to block between 1 and 2 percent of our star’s radiation to mitigate the effects of global warming.

Last year, a team of scientists from Harvard University and the University of Utah explored the idea of ​​placing dust at a “Lagrange point” between the Sun and Earth to combat climate change.

A different team proposed using an actual “parachute” attached to an asteroid to achieve the same effect.

However, the canopy will only be one part of the solution, as the Earth’s atmosphere will still trap heat in the form of greenhouse gas emissions.

Not everyone is on board with this idea. Critics said to now A sun canopy would be incredibly expensive and unrealistic, given the pace at which global warming is accelerating. Not to mention the beating that such a shadow would have to be able to take while exposed to outer space.

On the other hand, supporters say we should leave no stone unturned in finding solutions to climate change.

Rosen and his team are now looking to secure between $10 million and $20 million to build their prototype.

“We at the Technion will not save the planet,” he said. now. “But we will show that it can be done.”
