Is stratospheric aerosol injection safe?
It is considered relatively safe for the environment because volcanoes have been injecting sulfate aerosols into the stratosphere for eons and the biosphere naturally processes sulfates using multiple pathways in the sulfur biogeochemical cycle.
How effective is stratospheric aerosol injection?
A one-time stratospheric injection of SO2 from a volcanic eruption results in sulfate aerosols with an effective radius of about 0.5 μm, which would be very effective at back-scattering a portion of the incoming sunlight, cooling the surface.
What is stratospheric aerosol injection made of?
Materials. Various forms of sulfur were proposed as the injected substance, as this is in part how volcanic eruptions cool the planet. Precursor gases such as sulfur dioxide and hydrogen sulfide have been considered.
How much would stratospheric aerosol injection cost?
Depending upon the scenario analyzed, aggregate costs for SAI through the remainder of the century can range from roughly $250 billion to nearly $2.5 trillion, with an annual budget in the year 2100 of $7 to $72 billion (all in 2020 USD).
What is atmospheric aerosol injection?
Stratospheric Aerosol Injection (SAI) is a theoretical solar geoengineering proposal to spray large quantities of tiny reflective particles into the stratosphere, an upper layer of the Earth’s atmosphere, in order to cool the planet by reflecting sunlight back into space.
Why is it not a very good idea to use aerosol sprays?
Many aerosol sprays contain highly toxic chemicals like xylene and formaldehyde – yes the same chemical used to preserve anatomical specimens in a jar. These toxic ingredients also include neurotoxins and carcinogens that are extremely hazardous for adults, children and family pets.
How do jet engines produce aluminium oxide?
Aluminum oxide and/or other compounds may also be added to a jet’s fuel supply and emitted from the engine to generate a different type of chemical reaction. In most cases, when the onboard concoction makes contact with the air, the metals oxidize, generating nano-sized particulates that can remain aloft in the sky for up to 20 hours.
Could geoengineering be possible from an engineering perspective?
Dr. Gernot Wagner from Harvard University is an author of the paper. He said their study shows this type of geoengineering “… would be technically possible strictly from an engineering perspective.
How practical and costly would a solar geoengineering project be?
The researchers examined how practical and costly a hypothetical solar geoengineering project would be beginning 15 years from now. The aim would be to half the temperature increase caused by heat-trapping greenhouse gases. This method would mimic what large volcanoes do.
Are humans being poisoned by aluminium chemtrails?
A renowned nuclear scientist has published a paper confirming that humans are being poisoned by traces of aluminium via chemtrails. Dr. Marvin Herndon, PhD says that there is evidence of a secret government geoengineering program, injecting stratospheric particles/aerosoles into the atmosphere – endangering human health.
