In March 2017, two esteemed researchers, David Keith and Frank Keutsch, presented plans for the initial solar geoengineering experiment in the stratosphere. Solar geoengineering is a concept that involves dispersing particles into the atmosphere to reflect sunlight back into space as a way to combat climate change. Despite the potential benefits, critics raised concerns about the risks associated with manipulating the planet’s climate system on a large scale.
The proposed balloon experiment, intended to address these concerns, ultimately faced numerous challenges and was met with opposition. After a decade of planning, Harvard decided to terminate the project, highlighting the intricate balance between scientific exploration and ethical considerations.
On the other hand, the average age of nuclear power plants is increasing globally, with many reactors operating well beyond their initial expected lifespan. While economic factors have led to the closure of older reactors in some regions, there is growing interest in extending the lifespan of existing reactors due to their potential longevity and reliability.
Overall, both solar geoengineering and nuclear power present complex challenges that require careful consideration of environmental, social, and ethical implications in technological advancements.
