People keep using the term "geoengineering" but most, if pressed, couldn't explain the meaning nor how it is being done. So let me help:
"
engineering geology, or
geotechnical engineering deals with the discovery, development, and production and use of >>>subsurface earth resources<<<<, as well as the design and construction of earth works. Geoengineering is the application of geosciences, where mechanics, mathematics, physics, chemistry, and geology are used to understand and shape our interaction with the earth. Geoengineers work in areas of (1) mining, including surface and subsurface excavations, and rock burst mitigation; (2) energy, including hydraulic fracturing and drilling for exploration and production of water, oil, or gas; (3) infrastructure, including underground transportation systems and isolation of nuclear and
hazardous wastes; and (4) environment, including groundwater flow, contaminant transport and remediation, and hydraulic structures." (Hence the comment above about bulldozers forming in midair and crashing to earth)
Can anybody explain how supposedly spraying some mystery chemical(s) at 35,000-45,000 ft. will accomplish "geoengineering" miles below?
