What's Happening?
A study by Francisco Estrada and colleagues examines the potential economic impacts of solar geoengineering, specifically the risks associated with a sudden termination of such efforts. Solar geoengineering, which
involves techniques like spreading sulfur dioxide aerosols in the stratosphere to block sunlight, could halve the economic cost of climate change. However, if stopped abruptly, it could lead to a 'termination shock' with rapidly rebounding temperatures, causing greater damage than unabated global warming. The study models the risks of climate inaction compared to those of solar geoengineering, highlighting the need for continuous and coordinated efforts to avoid catastrophic outcomes.
Why It's Important?
The study underscores the complexities and risks associated with solar geoengineering as a potential solution to climate change. While it offers a way to mitigate some effects of global warming, the potential for a termination shock poses significant challenges. This highlights the importance of international cooperation and governance in managing geoengineering efforts to ensure they are safe and effective. The findings also emphasize the need for continued research into the trade-offs of geoengineering and the importance of reducing greenhouse gas emissions to mitigate climate change impacts.
