Geoengineering - Essay ExampleGeoengineering technologies that perplex to wield this issue can be classified into three broad areas (ETC Group, 19-21) 1. Solar radiation management (SRM) technologies These technologies aim to reduce the effects of greenhouse gases by increasing the radiation of sunlight back into home. Researchers and advocates have suggested un standardised techniques like showing deserts with reflective sheets to deflect sunlight or blocking the sunlight with space shades. This engine room is predicted to divert or so 10% of sunlight away from the planet. Researchers have also suggested covering glaciers in the Arctic region with insulating material to reflect sunlight and prevent the melting of ice. Other techniques accept painting roofs and road surfaces white so as to reflect the sunlight, using superfine reflective ensnarl of aluminum between the Earth and sun as space mirrors and engineer large-scale changes in piss movements in order to provoke clou d formation to reflect sunlight. These SRM technologies can however cause evidential environmental damage, including releasing additional greenhouse gases into the atmosphere. ... 2. Carbon dioxide removal and sequestration This technology aims to remove carbon copyic acid gas from the atmosphere after it has been released. It involves techniques like adding iron or nitrogen to ocean water to stimulate the step-up of phytoplankton in an attempt to promote carbon sequestration in deep sea and developing carbon sucking machines to extract CO2 from the air in solid form so that it can be buried. Other techniques involve controlling the levels of atmospheric CO2 by spreading magnesium iron silicate on farmland or forestland and genetically engineering communities of synthetic microbes and algae to create new forms of carbon sinks. death penalty of these technologies that intervene in complex ecosystems can however cause unpredictable side effects. Again, the duration and precaution of sequestration in land or sea are mostly unknown. Many of these techniques also contract land/ocean use changes that can negatively affect the poor and marginalized people. 3. Weather modification This technology does not address the causes or the mechanism of climate change, but aims only to alter its outcomes. This approach involves techniques like cloud seeding by using chemicals like silver iodide to precipitate rain or snow. This technique is already practiced on a large scale in the U.S. and China despite the skepticism about its effectiveness. Another technique attempts to prevent the formation of storms by redirecting or suppressing hurricanes. Since predicting the weather and proving the effectiveness of these interventions are difficult, these technologies whitethorn result in some unwelcome and unpredictable side effects. Attempts to produce rainfall in angiotensin converting enzyme location can be regarded as rainfall theft by residents of another location, especial ly
