This Scientist Wants to Block the Sun to Cool the Earth
There are a bunch of issues:
If you let a sabretooth tiger loose into a playground full of unsuspecting children in order to catch the rats that are eating all the shrubs, does it fail catastrophically? Or was it just catastrophic to begin with?
In the struggle against human-caused climate change, this is a completely new avenue for humans to change the climate.
Me too!
Say the line Bart!
Sigh Simpsons did it
YAAAAAAAAY!
I don’t doubt that. However, mobilizing a truly sufficient “mundane” response may fail. If it does, the end result may indtead be a global response in the form of drastic geoengineering when the consequences of climate change are truly starting to have an effect.
The fact that these sorts of solutions exist is also why I really don’t vibe with doomers. Climate change is not going to be the “end of the world”, or even the end of civilization. Humanity will prevail, the real question is how. Climate change is a (relatively) slow catastrophy, and the worst case isn’t everybody dead, but rather a miserable existence where where global standard of living is thrown back maybe a hundred years with the added bonus of our enviroment being generally miserable to live in.
In this case, it hasn’t been happening intentionally at a meaningful scale; you’d be able to look up and see the thin haze from it, and use a spectrometer to figure out that it’s not water vapor.
What has happened is that ordinary sulphur mixed with fossil fuels has produced particulates lower in the atmosphere. These turn into sulfuric acid when in contact with water, resulting in acid rain. Policies to sharply lower sulfate particle emissions have resulted in that becoming far less of a problem, but also accelerated warming in recent years.
Blocking the sun is not a practical solution. Putting something up in the atmosphere is untested and super dangerous. It could cause all life on Earth to die out like the Matrix.
Physically blocking the sun is also practically impossible. It requires that we put an object in space in a Lagrange point (gravitationally stable points around Earth) which is very far away and the sun shield would have to be approximately the size of Brazil. Launching that much material into space and getting it into position, and then unfurling it would be a HUUUUUUGE undertaking the likes of which we have never seen. Plus, launching all those rockets, mining the materials, etc, would emit so many tonnes of green house gasses that by the time we actually did it we might be in an even worse position.
I have a great idea on how to block the sun!
They’re called trees.
Far safer to bump earth’s orbit a notch or two further out.
And while we’re at it, adjust the axis tilt a bit.
Let Musk handle it.

It is easier to think about blocking the sun than to overcome capitalism that is destroying the planet
Capitalist Realism in its essence
We’re doomed
Delusional, just insane.
Technology will not save us, but guillotines will.

Global warming is nothing but a math equation at the end of the day. Change the input value, change the result.
The real problem is what you do with all the snakes after they eat the mice.
