One way to combat global warming — the creation of the atmosphere of the screen from sunlight from specially sputtered particles — will lead to the fact that the sky turns white and will be up to five times brighter, according to an American study published in the journal Geophysical Research Letters.
One of the most popular global geoengineering projects to combat global warming — spraying sulphate aerosols (fine particulate matter) in the lower atmosphere. It is assumed that this will create a screen reflecting solar radiation back into space, and slow the rate of warming. The idea of the project came after the eruption of Mount Pinatubo in the Philippines in 1991, when the stratosphere fell 20 million tons of sulfur dioxide. Then, from 1991 to 1993, the average world temperature has decreased by about 0.5 degrees Celsius.
Scientists at Caltech (USA) found that increasing the amount of aerosols in the atmosphere will have side effects, one of which — a much lighter color of the sky in the daytime. It is estimated that 2% of the screening sunlight can make the sky five times brighter and brighter. Heaven preserve blue tint, but in all the land will look "whitish" and hazy, as over a major city on a hot afternoon.
Scientists note that there are a number of effects that can occur when spraying aerosol. For example, after the sun in the sky for a long time will be visible glow like the aurora.
"Our study provides another good reason for people to think about whether you want to choose this path. We investigated only the physics of the atmosphere and the impact" whitish heaven "will have on the psyche of people — no one knows … But that it will — no doubt, "- said one of the study's authors, of California Institute of Technology (USA), Ben Kravitz (Ben Kravitz), whose words the newspaper quoted Science Daily.
Another effect that scientists foresee — the uncontrolled growth of all vegetation on the planet. New lighting conditions with the brightness of a lamp as the light of day, will inevitably cause accelerated photosynthesis, which will be withdrawn from the atmosphere is much more CO2 required for this biochemical reaction.
