Sentences with phrase «aerosol injection»

The phrase "aerosol injection" refers to the process of releasing tiny particles or droplets into the air (aerosol) usually using a spray or similar mechanism. This can be done for various purposes such as delivering medication, dispersing chemicals, or creating artificial clouds for scientific research. Full definition

«The Potential Role of State Responsibility in Solar Aerosol Injection Liability.»
Otto then takes us through the failure of cap - and - trade as an originally Republican idea that is now ridiculed as experimenting with the economy, and the rise of proposals for geoengineering solutions such as sulfur aerosol injections — an idea that «is easily the riskiest suggestion in the history of human civilization,» which resembles «taking up a crack habit.»
Beyond that, critics say, regular aerosol injections would change the sky's color, ruin astronomy for optical telescopes on Earth, and remove the incentive for nations to clean up their own acts.

The controversial approach, known as stratospheric aerosol injection, is designed to effectively cool the Earth's surface by reflecting some sunlight before it reaches the surface.
The amount of sunlight reflected also depends on several factors, including the distribution of injected aerosols, ambient levels of water vapor and pollution, and the timing of aerosol injections (because cloud brightening is only meaningful in the daytime).
Climate modeler Christopher Bretherton of the University of Washington, Seattle, called the study «good, solid, important work... [suggesting] stratospheric aerosol injection is an approach to compensate greenhouse warming that is worthy of further study.»
The results indicate that aerosol injections can be carefully tailored to achieve desired results, such as a minimal albedo increase near the equator, rather than a globally uniform response.
The creation of these artificial clouds are known by several terms: aerial spraying, aerosol spraying, solar radiation management, or stratospheric aerosol injection.
Are you saying that the loss of these aerosol injections will create such as large, sudden increase in GW that they will get the same kind of disruptions in rain patterns anyway?
That means committing the future generations to continue the aerosol injection basically every year more or less forever.
They are bringing this out of the closet under the guise of «climate geo - engineering» via programs such as SRM, SAI, and SAG (Solar Radiation Management, Stratospheric Aerosol Injection and Stratospheric Aerosol Geoengineering).
And second, direct further use of stratospheric aerosol injection (SAI)-- but in the opposite hemisphere, so as to partially stabilise impacts on precipitation (while possibly further forcing down global temperature).
It seems ironic therefore, but plausible all the same, that an episode of cooling through «natural» SRM might be more readily interpreted as an «emergency» and (ab) used to justify human efforts to take control of the climate system through stratospheric aerosol injection than accelerated warming.
The study focuses on one proposed type of SRM, known as a «stratospheric aerosol injection», which involves sending up substances to the stratosphere that are known to have a cooling effect on the climate.
