British scientists have "artificial volcano" save the planet
It is known that volcanic eruptions, similar to what happened in the Philippines in 1991, have the ability to cool. In Britain since the end of 2011 an experiment to pump water at a distance of one kilometer from the ground into the air to test a new model of climate cooling, with which to launch into the stratosphere, sulfuric acid particles, capable of reflecting the sun.
A new experimental model of an artificial volcano is necessary for possible protection from damaging effects of climate change. The experiment is the first of its kind, in which a distance of 20 kilometers from the earth through a special hose stratosphere will be pumped sulfuric acid particles. The system will be supported by a balloon the size of a stadium filled with hydrogen. The aim of the experiment is geoengineering, or, according to the Royal Society of London, "deliberate large-scale management of the environment of the planet." Thus, scientists are trying to artificially restore the natural cooling of the Earth during volcanic eruptions.
The experiment is part of a project entitled "The infusion of particles in the stratosphere for climate change." He was inspired by the eruption of Mount Pinatubo in 1991, during which time the atmosphere was emitted over 20 million tons of sulfuric acid particles, causing cooling of the Earth by 0.5 degrees Celsius over the next 18 months. If the experiment is successful, the system will balloon with a hose will be used for further injection of particles into the stratosphere, thereby curbing some of the effects of global warming.
"The first time people will not engage in geoengineering in the laboratory, but in practice, at least until the present geo-engineering humanity has not yet matured," said lead scientist Matthew Watson. During the experiment, will decide on the most suitable choice for particles that can reflect the light, to the extent necessary and possible consequences of unaccounted infusions of particles into the stratosphere, as acid rain, ozone depletion and the violation of weather types.
In the first phase of the experiment, carried out in October 2011, establishing the degree of efficiency of the balloon with a hose to run the reflective particles. An experiment was the old airfield in Norfolk, England. By kilometer simple Water hose supported balloon is pumped 1.8 liters of water per minute to a maximum of 190 liters, which evaporate or be deposited on the ground. The results obtained in the experiment data will be used in the design of system start at 20 kilometers.
Scientists have proposed similar methods for Atmospheric Research, which were made with the balloon, missiles, aircraft, chimneys, etc. But, according to British scientists, the system with a hose until the balloon is the most bankable project. Even with further testing of the project will cost $ 5 billion. Experiments with water thought to be harmless to the environment, that, they did not violate international agreements on conservation of biological diversity.
However, Canadian scientists believe that the experiment is a part of the grand plan, which would have damaging consequences, as large-scale drought. Computer models of sulfuric acid clouds found potentially dangerous reduction in the Asian and African monsoons, leading to a significant decrease in the yield on the multi-million territories. Scientists insist that British colleagues built a computer model of careful interaction of sulphate particles to the ozone layer and their influence on the water cycle. Although the British researchers agree with this proposal, they also believe that the experiment with water was just necessary to check how the system is viable in the real world.
Of course, geoengineering will not reduce carbon dioxide emissions by 80%, which, according to some scientists, could help avoid dangerous climate change. However, the cooling effect of clouds is sulfate immediate solution to some other problems, as the melting of Arctic ice.
