Geoengineering Global Concern
Geoengineering
Geoengineering refers to deliberate, large-scale interventions in the Earth's climate system to counteract the adverse effects of global warming.
Basically
In layman's terms this means placing a layer of a dusty type material similar to what erupts from volcanoes, high up in the sky.
Why?
Observations after large volcanic eruptions suggest they have an overall cooling effect upon the Earth's climate.
Types of Geoengineering
Solar Radiation Management (SRM) is a specific type of geoengineering which involves reflecting sunlight back into space in order to reduce the amount of solar energy absorbed by the Earth.
One of the most frequently discussed methods is the use of Stratospheric Aerosol Injection (SAI).
The concept underlying SAI is to inject tiny particles into the stratosphere to scatter a portion of the incoming sunlight, thereby cooling the Earth's surface.
This approach has been inspired by the cooling effect observed after large volcanic eruptions have released aerosols into the atmosphere.
Observations suggest a colossal volcanic eruption in 1815 led to what is known as the 1816 Year Without a Summer.
The primary cause of the Year Without a Summer was the Volcanic Eruption of 13,000ft high volcano Mount Tambora, on the island of Sumbawa, near Bali, Indonesia.
The Mount Tambora volcanic eruption took place in April 1815, with a Volcanic Explosivity Index (VEI) ranking of 7, it was a colossal event and was one of the greatest eruptions in history.
"Causing a volcanic winter and average global temperatures to decrease by 0.4–0.7°C.
Summer temperatures in Europe were the coldest of any on record between the years of 1766 and 2000.
This resulted in major food shortages across the Northern Hemisphere." (Wikipedia)
VEI is a relative measure of explosiveness
