(CNN)Scientists are proposing an ingenious but as-yet-unproven way to tackle climate change: spraying sun-dimming chemicals into the Earth's atmosphere.
The research by scientists at Harvard and Yale universities, published in the journal Environmental Research Letters, proposes using a technique known as stratospheric aerosol injection, which they say could cut the rate of global warming in half.
The technique would involve spraying large amounts of sulfate particles into the Earth's lower stratosphere at altitudes as high as 12 miles. The scientists propose delivering the sulfates with specially designed high-altitude aircraft, balloons or large naval-style guns.

Stratospheric aerosol injection would involve spraying sulfate particles into the Earth's stratosphere at altitudes as high as 12 miles.
Despite the technology being undeveloped and with no existing aircraft suitable for adaptation, the researchers say that "developing a new, purpose-built tanker with substantial payload capabilities would neither be technologically difficult nor prohibitively expensive."
They estimate the total cost of launching a hypothetical system in 15 years' time at around $3.5 billion, with running costs of $2.25 billion a year over a 15-year period.
The report does, however, acknowledge that the technique is purely hypothetical.

"We make no judgment about the desirability of SAI," the report states. "We simply show that a hypothetical deployment program commencing 15 years hence, while both highly uncertain and ambitious, would indeed be technically possible from an engineering perspective. It would also be remarkably inexpensive."
The researchers also acknowledge potential risks: coordination between multiple countries in both hemispheres would be required, and stratospheric aerosol injection techniques could jeopardize crop yields, lead to droughts or cause extreme weather.
The proposals also don't address the issue of rising greenhouse gas emissions, which are a leading cause of global warming.

No G20 countries are meeting climate targets, says report

And despite the conviction of the report's authors, other experts were skeptical.
"From the point of view of climate economics, solar radiation management is still a much worse solution than greenhouse gas emissions: more costly and much more risky over the long run," said Philippe Thalmann of the École Polytechnique Fédérale de Lausanne, an expert in the economics of climate change.
David Archer of the Department of Geophysical Science at the University of Chicago said, "The problem with engineering climate in this way is that it's only a temporary Band-Aid covering a problem that will persist essentially forever, actually hundreds of thousands of years for fossil fuel CO2 to finally go away naturally.
"It will be tempting to continue to procrastinate on cleaning up our energy system, but we'd be leaving the planet on a form of life-support. If a future generation failed to pay their climate bill they would get all of our warming all at once."
Let's just inject even more chemicals into the air, that will definitely fix things and not make them worse!

it isn't reversible.
releasing gas into the atmosphere is easy, but removing it is really hard.

if it were feasible, we could just remove excess CO2 from the atmosphere directly to tone down the greenhouse effect, but the technology to do this on a large scale simply does not exist.

You know sometimes it seems that Scientists and other smart people overthink simpler solutions. I would say that the bigger issue is fighting deforestation in Africa and South America where the people are understandibly short sighted and don't realize that their trees are their best economic resource and once it is gone, it is hard to come back

Hah, not like it matters. CO2 levels rise centuries AFTER temperatures rise, so all you'd do by sucking out CO2 is really confuse some aliens in the future when the temp/CO2 curve makes no sense when they pull some ice cores in 10000 years.

I mean, much like my shark repelling magic rock, this would work, in that the problem it claims to solve doesn't exist, so after the solution was applied it's likely the problem would continue not to exist (although at least my shark repelling magic rock has no possibilities of attracting more sharks!)

Global warming theory is fake bullshit that they keep changing because it never ever has made an accurate prediction. They change the numbers to make it kinda fit the observed temperatures. They make up theories that directly violate known laws of physics (Did you know from 2000-2016, all the global warming heat went into the bottom of the ocean instead of warming the surface? Weird that heat sunk that one time)

It works because they keep telling you "Smart people believe this theory and only idiots disagree". Nobody wants to look stupid. But they keep changing it.

Also, me sperging out at a global warming topic is pretty much a kiwi farms bingo square by now. I bet you guys knew this was coming...
 
Strawman Scientist: "There are too many chemicals in the atmosphere and it's killing the ozone layer and the polar bears are sad!"

Me: "So how do we fix this?"

SS: "ADD MORE CHEMICALS."

Me: "What, but that hardly--"

SS: "BLOT OUT THE SUN."

Me: "Oh come on now. I'm not even a scientist and that sounds--"

SS: "CORRECT. I AM SCIENTIST. THIS IS SMART."

Me: "...Are...are you vampires?"

SS: "...THEY KNOW TOO MUCH!!"
