Geoengineering involves large-scale scientific efforts to control or modify the Earth’s environment. This high-tech approach has a long history of attempts at weather control and terraforming. Despite its potential, geoengineering is often misunderstood, leading to more conspiracy theories than concrete results.
Today, techniques like carbon capture and solar geoengineering are considered by some as viable methods to combat climate change. The planet is facing rising tides, heat waves, droughts, hurricanes, and melting ice caps, making it increasingly harsh and uninhabitable. As scientists search for ways to reverse climate change, some view geoengineering as a potential solution, though it remains a controversial topic.
The science behind geoengineering is real and could potentially save us, but it also carries risks of severe consequences. Definitions of geoengineering vary, complicating efforts to clearly define its scope. Two main categories are particularly significant: carbon dioxide removal and solar radiation management.
Carbon dioxide removal involves using engineering methods—whether through machines or plants—to extract excess carbon dioxide from the atmosphere and store it safely. Solar radiation management aims to manipulate the planet’s reflectivity to counteract warming.
Concerns about geoengineering arise from fears of unintended consequences and the unknowns associated with large-scale implementation. There is anxiety about whether such interventions could disrupt weather patterns or create disparities in climate impacts across different regions. Critics argue that geoengineering is merely a temporary fix that does not address the root cause of climate change: greenhouse gas emissions.
Research into geoengineering is essential, not to determine if we should implement it, but to explore its possibilities and understand its implications. The global nature of atmospheric interventions raises complex policy questions about responsibility and funding.
Early estimates suggest that a program to cool the Earth could cost a few billion dollars a year. However, concerns exist about who would undertake such initiatives and the potential for clandestine operations by nations under pressure to address climate change.
Organizations like Silver Lining are exploring various options for quickly reducing warming, including marine cloud brightening, which involves spraying saltwater to enhance cloud reflectivity. The goal is to conduct small-scale experiments to gather data on the effectiveness of these techniques, with a strong emphasis on the need for careful consideration and global consensus before any large-scale implementation.
The debate surrounding geoengineering is complex, with valid concerns from both proponents and opponents. The scientific community acknowledges that we still have much to learn about the potential benefits and risks of these methods.

This is where you create clouds that can help cool the Earth. The goal is to generate clouds with many droplets, similar to fog.
Hello, I’m Athena Brensberger, and welcome to “Suppressed Science.”
Geoengineering refers to large-scale scientific efforts aimed at controlling or modifying the planet. It represents a high-tech approach in a long history of attempts at weather control and terraforming. This field is often misunderstood and can lead to more conspiracy theories than concrete results.
Today, techniques like carbon capture and solar geoengineering are viewed by some as viable methods to combat the existential threat of climate change. Rising tides, heat waves, droughts, hurricanes, and melting ice caps are all signs of our planet becoming increasingly harsh and uninhabitable. As scientists seek ways to reverse climate change, some believe geoengineering may be our only hope, though it is a controversial topic.
The science behind geoengineering is real, and it may one day save us, but it could also lead to severe consequences. Definitions of geoengineering can vary, making it difficult to pin down what it truly entails.
I’m David Victor, a professor at UC San Diego, where I teach atmospheric and climate science. I also work in mechanical and aerospace engineering, focusing on deep decarbonization and how the electric grid can adapt to emission reduction needs.
To clarify, geoengineering encompasses various activities, but two main categories are particularly significant: carbon dioxide removal and solar radiation management. Carbon dioxide removal involves engineering methods—whether through machines or plants—to extract excess carbon dioxide from the atmosphere and store it safely. Solar radiation management aims to manipulate the planet’s reflectivity to counteract warming.
Concerns about geoengineering stem from the fear of unintended consequences and the unknowns associated with large-scale implementation. There is anxiety about whether such interventions could disrupt weather patterns or create disparities in climate impacts across different regions. Critics argue that geoengineering is merely a temporary fix that does not address the root cause of climate change: greenhouse gas emissions.
I wanted to continue my research on geoengineering, so I met with Professor Ted Parsons at UCLA. He specializes in environmental law and has been involved in climate policy for many years.
In summary, carbon dioxide removal is often viewed with uncritical enthusiasm, while solar geoengineering is met with more skepticism. The process of stratospheric solar radiation management involves releasing reflective particles into the stratosphere to cool the planet, a method inspired by natural volcanic eruptions that have previously cooled the Earth.
People fear that geoengineering could be seen as a quick fix, undermining the urgent need for emission reductions. The priority must always be to cut emissions to near zero.
As an atmospheric chemist, I emphasize that all proposed methods to increase reflectivity come with significant uncertainties and potential unintended consequences. For example, introducing aerosols into the stratosphere could damage the ozone layer and alter precipitation patterns.
Research into geoengineering is essential, not to determine if we should implement it, but to explore its possibilities and understand its implications. The global nature of atmospheric interventions raises complex policy questions about responsibility and funding.
Interestingly, early estimates suggest that a program to cool the Earth could cost a few billion dollars a year. However, there are concerns about who would undertake such initiatives and the potential for clandestine operations by nations under pressure to address climate change.
I spoke with Kelly Wanzer, founder of Silver Lining, a nonprofit focused on the near-term risks of climate change. They are exploring various options for quickly reducing warming, including marine cloud brightening, which involves spraying saltwater to enhance cloud reflectivity.
The goal is to conduct small-scale experiments to gather data on the effectiveness of these techniques. However, there is a strong emphasis on the need for careful consideration and global consensus before any large-scale implementation.
