Let's just inject even more chemicals into the air, that will definitely fix things and not make them worse!

(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.

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."
