With global warming offered fight with diamond dust
Climate scientists from Harvard University have found a new way to deal with global warming. They offer spraying in the sky diamond nano-sized particles. This, in their opinion, is much safer sulphate mixture with water - a method that actively discussed recently. And the cost, "Diamond" method of just five dollars to each inhabitant of the Earth.
As the portal Nature, to combat global warming is now widely discussed new ways of geo-engineering - for example, spraying a mixture of sulfates in the sky with water, so that she reflected and scatter sunlight. However, according to scientists from Harvard, they have found a safer method of man-made climate cooling, rather than spraying sulphate aerosols. This dust particles of diamond or nanoscale alumina.
After contact with sulfates into the atmosphere, it forms sulfuric acid, which damages the ozone layer. Furthermore, sulfates absorb light at certain frequencies because of which the lower part of the stratosphere is heated - is, in turn, in an unpredictable way affect the climate. Finally, sulfates, scatter light: it will accelerate the growth of plants, but will reduce the efficiency of the solar cells. Alumina and diamonds will not lead to such problems, but the diamond dust, according to scientists, to be 50% more efficient than alumina. However, this method is rather expensive, despite the fact that the diamond powder is much cheaper solid diamonds (about $ 100 per kilogram). According to specialists, we need to spray every year hundreds of thousands of tonnes of diamond dust that will cost several billion dollars.
"With all the expensive diamonds this method of control solar radiation is not unrealistic," - says climatologist Debra Vayzenshtayn. Climate scientists are confident that 2065 spray 450 thousand. Tonnes will cost each of the ten billion people on Earth just five dollars.
Science "climate engineering" (or "geo-engineering") studies the development and implementation of technology-conscious and a reasonable influence on the Earth's climate on a global scale. Algorithms and technology that uses geo-engineering scientists conventionally divided into two main groups. In the first group are methods for reducing the CO2 content in the atmosphere. For example, climatologists offer to dissolve in the waters of the seas and oceans of iron sulfates governing the share of CO2 in the atmosphere through photosynthesis. Or use a kind of "vacuum cleaner" that can filter out the carbon monoxide from the air.
In the second group of geoengineering techniques are ways to control and regulate the Earth's sun exposure. Along with the installation space of huge parabolic mirrors here are methods to improve the reflectivity of the Earth's surface and the clouds or the atmosphere in general. One option may be an aerosol comprising sulfur particles. Sprayed into the atmosphere, it creates a kind of protective dome portion reflecting sunlight back into space.
