Deploying giant space mirrors and spraying particles from stadium-sized balloons may sound like an engineer’s wild fantasy,but climate models suggest that the potential of geoengineering to offset rising atmospheric carbon dioxide may be significantly overstated.
Through a variety of computer simulations used for reporting to the Intergovernmental Panel on Climate Change (IPCC), the team investigated a scenario where an increase in the world’s atmospheric carbon dioxide levels was balanced by a “dimming” of the sun.
Across all four models tested, the team showed that geoengineering could lead to adverse effects on the Earth’s climate, including a REDUCTION IN GLOBAL RAINFALL. therefore concluded that geoengineering could not be a substitute for the reduction of greenhouse gas emissions.
