Would a massive shade between Earth and the sun help slow climate change?
Popular Science ^ | August 9, 2023 | BY JON KELVEY

Some of the most exotic solutions to climate change are the various forms of geoengineering. Such proposals aim to reduce global warming by shrinking the amount of solar radiation that reaches Earth’s surface—by, say, injecting large amounts of sulfur dioxide or dust into the air to mimic the cooling effect of large volcanic eruptions. Or building catapults to launch lunar dust into orbit around Earth and intercept the sun’s rays in the space near our planet.

But University of Hawaii cosmologist István Szapudi has an even more far-out idea: place a 372,000-mile-wide sun shade tethered to a captured asteroid between Earth and the sun to reduce the amount of solar radiation reaching our planet by 1.7 percent. His analysis is agnostic to the shade’s shape, though he imagines it could be a circular shade made of triangular segments, able to open or close like flower petals to allow variable amounts of sunlight through.

“It’s not going to cast a sharp shadow,” Szapudi says. ”Maybe with a telescope you could notice that there is something in front of the sun. But other than that, it would just be that people would notice that the weather is a little bit better.”

He readily admits that this concept would require millions of dollars investment in just preliminary engineering studies to see if it is really possible. “Of course, it’s unrealistic to actually do this, so hopefully, we will slowly give up fossil fuels,” Szapudi says, citing a much more mainstream goal to curb a source of climate change. “But that’s a very long-term process.”

It would be better, faster and cheaper to just eliminate the proglodytes.

Maybe they should go up to the Sun in a rocket ship to build the massive shade. To protect themselves, of course they will have to go at night when it is cooler.
There! That’s my scientific theory and it makes as much sense as their theory.

Other than the total destruction of life on earth, what could go wrong?

It will cool the Earth while simultaneously boosting solar panel output and food production! /s

Dangerous lunatics.

This idea is a tacet admission that climate change is brought about by the sun.

How dare he??? We must get rid of fossil fuels IMMEDIATELY!!! CANCEL HIM!!!

For sure this astronomer is on the take just like Xiden or most lefties, they of all organisms that have the capability to think in the Galaxy or Universe know that 1/100 of a percent of CO2 is not going to burn our planet up in a few short years. Perhaps this liar should study volcanism for awhile looking over a cliff on a real windy day in the Circle of Fire.

Vast project, half-vast idea.

The very mechanics of placing a huge Mylar film across the the rays of the sun that would shade a significant portion of the planet earth are incomprehensible. How would it be launched, how would it be spread out effectively, and what prevents the rays of the sun for simply propelling the opened sheet like a huge sail, dissipating its original purpose entirely?

So many questions and so little critical thinking.

Of course we are, to a degree (no pun intended) as both federal taxpayers and Hawaiian taxpayers are on the hook for at least a percentage of the school’s budget. Perhaps this lying clown is unaware of our $40 TRILLION nation debt before the end of this decade will destroy our nation in matter of years rather a matter of thousands of centuries.

Just thank the Lord and that this will never get beyond the stupid idea phase

I’m pretty sure they’ll spend a ton of money on it before it goes the way of Solyndra

You sneak up on the sun and deploy it at night

People might be educated but I don’t think they understand aspect ratio whilst standing here on this rock and looking into outer space...

From 2004, a federal grant...

Check out the amount.

It’s good to have low friends in high places.

Would a frontal lobotomy help correct this writer’s thinking? Would changing the name of this magazine to “Popular Rubbish” be a corrective action?
