One of the most important geoengineering procedures in these times ̶ Ozone Layer Geoengineering ̶ is an experiment that holds several opportunities for the earth climate system. Ozone layer depletion is not an unfamiliar news and may be more troubling in time to come since Green House Gases (GHGs) somewhat contribute to it.
Geoengineering is gaining more grounds for discourse in the scientific community of late and may grow in coming years to “a risk we should take” if in 2020 the international agreement to curb emissions is not effected and climate change poses unquestionable risks to the environment.
Geoengineering is canvassed for by groups to be studied further and funnel it as a safe inter-national procedure when necessary for deployment. Geoengineering can come as some suggestions have been provided to beneficially have it from one country if it will serve others and if they are also assured of safety.
Hundreds of arguments still lie ahead for geoengineering as more people understand it and as those who believe that developed nations are creepy about climate change take it as a reason for activism. It is said that geoengineering whenever it will be deployed will be within a safe range so there will not be ‘unintended risks’ feared.
Geoengineering the ozone layer is a very safe geoengineering proposal, its submits that oxygen ̶ an essential gas for protection reactions in the ozone layer ̶ is injected to depleted parts of the ozone layer to be naturally converted to ozone for protection reactions. This research is very workable because of the stability of oxygen gas for this purpose and the familiarity of man with outer space.
The Ozone Layer Geoengineering (or OLG) research is principally in its review stage and may be necessary for deployment with time. OLG is important for many reasons as we cannot bet on what can come in unknowns for atmospheric anomalies in future. Some space-based geoengineering procedures may have damaging effects on the ozone layer but the OLG will be a scheme to heal it.
One thing that assures the safety of the OLG experiment is the knowledge that lost ̶ useful ̶ gases in the ozone layer are being refilled. It is similar to refilling a gas container with a certain amount of gas to cover for a previous loss. Since it is within a given range and within the capacity of the container, refilling is safe.
Around 3% of the ozone layer is depleted for the action of Ozone Depleting Substances (ODSs); these depleted parts are the target points for this research. Oxygen injection will systematically avoid ODS-high areas and will come where impact will be high.
The OLG may someday become the core of space-based geoengineering as most risks feared for its SRM ̶ Solar Radiation Management ̶ aspect does not apply with OLG. The OLG is capable for solutions to ozone layer depletion ̶ or ozone hole ̶ eventualities, it is with the scientific community to see this opportunity and promote further review of it.
