Deep dives
Climate Overshoot Commission and the Paris Peace Forum
The Climate Overshoot Commission was established by the Paris Peace Forum and is a multi-stakeholder coalition focused on addressing global issues related to climate change. The commission aims to provide solutions and recommendations to prevent overshooting the 1.5-degree warming limit agreed upon in the Paris Agreement. It consists of world leaders, diplomats, economists, and scientists who recognize the urgent need for action.
Solar Geoengineering and the Need for Exploration
Solar geoengineering, specifically solar radiation modification, is an off-the-wall idea that has gained traction as a potential solution to mitigate global warming. By reflecting sunlight through the release of sulfur dioxide into the upper atmosphere, it aims to cool the planet and counter rising temperatures. The Climate Overshoot Commission highlights that solar geoengineering should be more fully explored, but emphasizes caution due to the controversial and risky nature of this approach.
The Risks and Challenges of Solar Geoengineering
While solar geoengineering may offer a way to temporarily lower global temperatures, there are significant risks and challenges associated with this approach. The unintended consequences of manipulating solar radiation are not fully understood, and the distribution of these consequences could be unfair and impact vulnerable regions disproportionally. The Commission recommends a moratorium on large-scale experiments until further research and international governance are in place, including transparency and cooperation among nations.
Addressing Climate Change through Cut, Adapt, Remove, and Explore
The Climate Overshoot Commission proposes a comprehensive approach to addressing climate change called CARE: Cut, Adapt, Remove, and Explore. This integrated strategy recognizes the need to cut emissions rapidly, adapt to the changing environment, remove existing carbon dioxide from the atmosphere, and explore options such as solar geoengineering. The Commission emphasizes the importance of investing in research, governance, and international cooperation to effectively implement these strategies and safeguard our planet's future.
