In 1827 the French physicist Joseph Fourier has assumed that the atmosphere of the ground carries out function some kind of glasses in a hothouse: air passes solar heat, not giving it to evaporate back in space. And it was right.
Scientific proposals for dispose a problem of global warming have at times fantastic character, but are considered by experts seriously because can appear useful, sooner or later.
Let’s see some ideas of scientists on rescue of the Earth from global warming.
Today the Earth absorbs 70 % of all radiation, which receives from the Sun, and consequently it is necessary something to think up to lower this parameter.
Astronomer Roger Ancel suggests to place around of the Earth millions lenses in diameter of 60 cm and weight few grams which will be capable to reflect solar beams. It will lead to decrease in solar radiation.
It is necessary to notice, that reduction of solar illumination on 1,6 % compensates growth of temperature on 1,75 Calvin (3 degrees of Fahrenheit).
The effect which renders dispersion of light on temperature, is observed, for example, at eruption of volcanoes when in an atmosphere the huge weight of particles and as a result the temperature gets falls.
According to other similar idea (article in magazine “Acta Astronauticaâ€) is supposed to create around of the Earth a ring of fine particles or spacecrafts with which it is possible to shade tropics to soften a climate. Reflecting particles can be taken from mountain development on the Earth, the Moon or on asteroids.
Expenses for these projects can appear very heavy: 500 billion dollars at accommodation of spacecrafts and from 6 up to 200 billion dollars in case of with particles.
Climatologist Wallace Broker suggests to disseminate in a stratosphere particles of sulfur at height over 15 km by means of spheres and planes of which will hold on at this level year-two. This project with dispersion of sulfur is estimated in 50 billion dollars.
