*Geoengineering seeks to alter the Earth itself to respond to the climate crisis. Two of the main ideas are to reduce incoming solar radiation by releasing aerosols high in the atmosphere to cool the planet, or to remove the excess greenhouse gas* *, mainly carbon dioxide, that has built up in the atmosphere over the past two centuries. Aerosols injected into the stratosphere by nature during volcanic eruptions can sometimes produce dramatic cooling effects, such as the “year without a summer” in 1816 following the eruption of Mt. Tambora in Indonesia. Solar radiation management* *seeks to add anthropogenic aerosols to the stratosphere to overcome the most severe effects of global warming such as massive heat waves. Carbon dioxide removal* *from the atmosphere can be done using photosynthetic plants, although the amount of available land for planting trees is limited and up to a trillion new trees would be needed to mitigate climate change* *. A second option is to engineer devices to capture it using various chemical processes and specialized machinery. The captured carbon must be stored or sequestered away from the atmosphere for periods of at least a century and the longer the better. All these options are under consideration by governments, research institutions, and venture capital investors. When combined with an energy switch away from fossil fuels* *, geoengineering techniques promise a way to mitigate the worst aspects of climate change* *.* -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
