Stratospheric aerosol geoengineering is the process of adding a layer of aerosol particles to the upper atmosphere aiming to diminish the effects of greenhouse gases caused by climate change.
Research shows that geoengineering can be achieved by injecting sulfur dioxide into the stratosphere.
Scientists have analyzed whether this approach could improve or worse the climate change outcomes. This was tested using various climate settings with different temperatures.
The lead analyst, Professor Peter Irvine, stated that in most regions, the experiment was proven to be successful. However, 9% of the land area is subject to facing even more significant climate change than usual.
Nevertheless, the researchers’ team is worried that the purpose of solar geoengineering is treating the effects of climate change, rather than tackling the root cause. Therefore, a reduction in the gas emissions should be considered to prevent climate change.
Geoengineering might be the solution to fight climate change
The study suggests that combining solar geoengineering with limiting the CO2 emissions has more chances to succeed in lowering the climate change effects. One thing still questionable is the impact of solar geoengineering on a more extensive period.
As a result, the research was based on data from Geoengineering Large Ensemble Study, where a simulated climate area was used to determine changes, while stratospheric aerosol geoengineering was introduced. The experimentation aimed to determine fluctuations in temperature, which is the leading cause of climate change threats.
Even though many tests have already been made, uncertainties are still present. Professor David Keith, a co-author of the study, is still reluctant whether to believe or not if gas emission cuts combined with a decrease in solar radiation diminish notably climate risks.
He sees his study as a step forward in finding the truth since it is the first time research has shown effects on a regional level. Consequently, the team is currently researching and trying to comprehend better the print stratospheric aerosol geoengineering has on the environment.
