There are several proposals that conform to these broad categories, however, by now the plans are very General on environment and they occupy a marginal place in discussions on climate change. Geoengineering is the handling of solar radiation, response actions as spraying aerosols in the atmosphere, marine cloud whitening, send to space satellites with mirrors and whiten the surface of oceans, among others about the environment. The part that deals with the Elimination of carbon dioxide includes planting forests to use as carbon sinks or burn biomass instead of fossil fuels such as coal. Intend to cultivate large amounts of algae from which they can develop biofuel and controversially sprinkle minerals such as iron or limestone on parts of the ocean. Somewhat controversial for the environment.
The scientists emphasize that you should not think these technical solutions to climate change as substitutes for the reduction of greenhouse gas emissions. Required investigate to determine what adverse consequences can have those solutions and if work on the environment. There are fears about the ecological implications of geoengineering, it will be necessary to resolve political and Legal Affairs for more progress. I am concerned that you can ignore side effects that might have on other phenomena such as weather patterns or the nitrogen cycle. It is necessary to stop thinking about geoengineering as climate change technologies, are only a series of interconnected themes, this potential technology also raises thorny issues for international law and governance. It will be difficult to take measures of geoengineering without the knowledge of the Governments, but is not yet clear who has jurisdiction over this and which Governments or entities should respond in this respect. It is possible that for 2015 geoengineering options can use to negotiate at summits like the 15 Conference of the parties of the Convention of United Nations framework on climate change on the environment, held last year in Copenhagen, and which will take place this year in Cancun, is necessary to investigate more in geoengineering technologies in controversial issues that raises. A planetary scale geoengineering have big risks, but also know that you can reach a moment in which outweigh them the risk of climate change-induced emergencies.
