Geoengineering is not an extreme measure, but the next necessary step for the calibration of the Earth's climate if emissions of carbon dioxide significantly reduced in the near future, the Royal Society, the National Academy of Sciences of the United Kingdom, announced on Tuesday.
"It's an unpleasant truth that if we can significantly reduce CO2 emissions we are at a very inconvenient and difficult climate in the future, and geoengineering will be the only alternative, to limit the further increase in temperature," John Shepherd, chairman of the Royal Society of geoengineering study and a professor of science Earth system at the University of Southampton, said on behalf of the group.
In the report "geoengineering climate change: science, management and uncertainty" (PDF) called for reducing emissions of carbon dioxide as the primary means to stop climate change. But he looked at geoengineering - the engineering environment on a large scale is deliberately manipulating the climate in the world - very seriously.
In previous years, was the idea of geoengineering as an option of last resort, but the Royal Society stated that some of the safer methods of geoengineering as an aggressive planting of forests, can be implemented at present in connection with efforts to reduce carbon emissions.
With geoengineering has the potential to affect people on a global level, the group also recommended that international organizations like the UN Commission on Sustainable Development to proceed to the formulation of policies and means to resolve political conflicts expected geoengineering.
"Assuming that were established acceptable standards of efficiency, security, public recognition and value, so you need to make appropriate options geoengineering not be added to the portfolio of options that society will be necessary and may wish to use to combat the problems associated with climate change? " says.
With this in mind the group assessed the safety, cost, efficiency and speed of deployment of projects falling under two main classes of geoengineering: Carbon Dioxide Removal (CDR) and solar radiation Management (SRM).
CDR, efforts to remove greenhouse gases from the atmosphere, including things like deforestation, encouraging the growth of plankton, as well as carbon capture and storage in the form of buried carbon-rich biomass, or with Biochar for fuel.
SRM offers to manipulate the Earth so that it absorbs less solar radiation, it would seem that a more far-out options as painting all the roofs in a white reflecting sunlight, the deployment of thousands of space mirrors in Earth orbit to reflect sunlight, as well as spraying aerosol into the stratosphere .
Group said it usually favored CDR projects SRM, as they relate to processes closer to natural hazards, and side effects of SRM projects are unknown and therefore more dangerous.
