If engineers were to spray about 10 million metric tons
of sulfur dioxide droplets into the stratosphere each year between 2020 and 2070, the number of storm surge inundations produced by large hurricanes each year after 2070 drops by about half, the researchers report online today in the Proceedings of the National Academy of Sciences.
Not exact matches
The pollution is generally a mixture
of gases — such as carbon monoxide,
sulfur dioxide and nitrogen oxides — and particulate matter, microscopic solids or
droplets that can be inhaled into the lungs.
We can fill the stratosphere with plane - loads
of sulfur dioxide, which will form tiny
droplets of sulfuric acid that will reflect away excess sunlight and counter the warming.
Contribution
of volcanic eruptions: big volcanic eruptions emit great quantities
of SO2 (
sulfur dioxide) that form with water vapor sulfate
droplets that are lifted by the eruptive column to the stratosphere where they are carried by winds all over the world.
An estimated 20 million tons
of sulfur dioxide were let loose into the stratosphere, where they turned into
droplets of sulfuric acid that scattered the sun's light.
Sulfur dioxide is an aerosol that forms
droplets of sulphuric acid in the high atmosphere and reflects solar energy back into space, so these two volcanic eruptions had some short - to medium - term effects.
