LONDON (REUTERS) – It is possible to absorb solar chemicals that are well above Earth for a & # 39; hauling global warming "particularly cheap", costing US $ 2.25 billion ($ 3.09 billion) annually over 15 years, according to a survey by the US scientists.
Some researchers say that the geo-engineering method known as stratospheric aerosol (SAI) injection can tighten rising temperatures that cause climate change.
Despite this not to be sure and of course, it would be a including large pipes, cannons or planes designed specifically to stimulate large amounts of sulphate into a high level of the atmosphere to make a massive obstacle against the sun.
The total cost of the 15-year SDI financial effort was launched from US $ 3.5 billion, scientists at Harvard University in a report published in the Journal Environmental Letters magazine, said that there would be annual operating costs Approximately $ 2.25 billion per annum over 15 years.
By providing other means of use as a result of cost and feasibility, the research is carried out; Accepting that special planes can be designed to fly at a height of 20 kilometers and 25-ton passenger passengers.
Following direct help from a number of aircraft and engines, the scientists said they have designed its design that may be suitable and be ready to be used in 15 years, focusing on temperature change in half.
The scientists stressed that this is not an excellent situation.
"We do not make any comments that the SAI requests. We have shown that an induction program begins 15 years later, although both A very uncertain and ambitious, capable of being technically able from an engineering perspective. It would be very unimportant too, "said a report.
There are risks to technologies that may be proven. Scientists have said that ITS could be adversely affected by causing dry or severe weather conditions in other parts of the world, which can accumulate crops as well as public health and regulatory issues which may be there.
It also does not handle the & # 39; question about increasing carbon dioxide emissions, adding to it; biggest boiler of greenhouse glass for global warming.
Speaking of the study, Professor Phil Williamson at the University of East Anglia said: "Such situations are difficult for problems – and it would appear that international agreement was going on with such activities. "
