A review of studies on geoengineering has found that deliberately altering the weather as a method for stopping climate change will have negligible effects.
Regardless of where you stand, geoengineering has been a controversial topic in recent years, both as a subject of conspiracy research and environmental concerns. One of the reasons the topic is so controversial is because of the possible risks. At least one previous study has found that geoengineering could cause the white haze and loss of blue skies.
The promotion of geoengineering might actually cause more harm than good, including an increase in droughts. In February 2015, an international committee of scientists released a report stating that geoengineering techniques are not a viable alternative to reducing greenhouse gas emissions to combat the effects of climate change. The committee report called for further research and understanding of various geoengineering techniques, including carbon dioxide removal schemes and solar-radiation management before implementation.
The scientists found that SRM techniques are likely to present “serious known and possible unknown environmental, social, and political risks, including the possibility of being deployed unilaterally.” The report was sponsored by the National Academy of Sciences, the U.S. intelligence community, NASA, National Oceanic and Atmospheric Administration, and the U.S. Department of Energy.
