Large-scale interventions to control weather are a step into the unknown, says Chris Wright, and may also allow the worst emitters to continue unchecked ...

A downside, though, is that it will cost approximately $200 trillion. As the climate crisis deepens, scientists have been pondering ways to cool the planet. A new study proposes to spray millions ...

The only way to do that, most in the field agree, is to inject aerosols into the atmosphere to reflect sunlight and heat back into space. The leading candidate for such an endeavor right now is ...

Injecting these aerosols into the stratosphere — the layer of Earth's atmosphere that sits between ... then condenses to form fine sulfate aerosols that reflect sunlight back to space ...

A Greenland ice core shows that volcanoes quietly release at least three times as much sulfur into the Arctic atmosphere than ... timescales the amount of sulfate aerosols released during passive ...

While the concept of injecting sulfate aerosols into the atmosphere emerged as a potential solution, scientists have raised concerns about the environmental consequences. Artificially introducing ...

Now researchers have simulated what the sky may look like after injecting a blanket of various aerosols into the upper atmosphere (Environ ... with the injection of sulfate, calcium carbonate ...

And there was a lot of soot going into the atmosphere as a consequence ... into the earth system in this manner, injecting sulfate aerosols into the stratosphere where we don't know what the ...

Spending decades grinding up something approaching a quadrillion dollars worth of diamonds into dust ... particles in the atmosphere — is known as stratospheric aerosol injection.

Sulfate aerosols lead to cooling in the atmosphere. Past volcanic eruptions, such as that of nearby Pinatubo in 1991, have had this kind of cooling effect on the climate.
