Geoengineering And Global Warming

In order to maintain a healthy green planet; firstly, “planting more trees will absorb more carbon from the atmosphere” (Mackey 19). Secondly, the idea of geoengineering could be implied to stave off the issue of global warming. The global climate change is an incalculable issue today. You would rarely find a person not au fait with this issue. Melting glaciers, ocean acidification, rising sea levels, and increasing concentration of carbon dioxide in the atmosphere are all consequences of global warming. In order to reduce global warming, greenhouse gas emissions must dwindle, particularly the emission of carbon dioxide from burning fossil fuels. Approximately thirty percent of the carbon dioxide released in the atmosphere in past and present …show more content…
Afforestation and use of sustainable energy sources will help tackle the issue. Contiguous with that, geoengineering projects like ocean fertilization and engineered weathering could be used to reverse the global warming trend. Planting trees, which is afforestation could reduce global warming considerably. As we know the green plants give out oxygen and take in carbon dioxide from the atmosphere. Thus, absorbing large amounts of carbon from the atmosphere. When deforestation is carried out by humans, which is cutting of trees for obtaining timber, paper or to clear the land to use it as pasture for livestock without reforestation, which is planting new trees to replace the ones depleted, greenhouse gases such as carbon …show more content…
It is a scientific approach to tackle global warming. Geoengineering is an intentional modification of Earth’s atmosphere to tackle global warming. Nowadays the idea of geoengineering has entered a working stage and is expressing itself with a variety of proposed projects. “Carbon dioxide, once released into the atmosphere, stays there in excess of 100 years.” (Ralston 823). The geoengineering projects such as solar shields, ocean fertilization and engineered weathering will help reduce the amount of carbon dioxide released into the atmosphere. Launching solar shields into the orbit could reduce the solar radiation reaching the Earth’s surface by eight percent. Phytoplankton’s serve as a virtual carbon sink. Depositing iron filings in the oceans will encourage the growth of phytoplankton. Thus, reducing carbon. This is called ocean fertilization. Substituting carbonic acid in the oceans with hydrochloric acid will speed up the rate at which carbon dioxide is absorbed. Subsequently, another way to reduce the amount of carbon being on the rampage into the atmosphere is to paint rooftops white. Thus, reducing the amount of carbon dioxide released into the
