Climate Hacking: The Good and Bad of Geoengineering

The climate crisis is forcing everyone from scientists to engineers to get creative. How can the planet’s collective imagination find new ways to combat the adverse effects of human activity? This is where climate hacking comes in, which is a hotly debated mitigation method. What are the pros and cons of geoengineering, and what does it involve?

What Is Climate Hacking?

Climate hacking, also called geoengineering, is the practice of using technology to alter the planet and overcome or acclimate to climate change. These projects aim to reverse, delay, and prevent the adverse side effects. 

Geoengineering is also a larger field of science, including soil reinforcement and biomass sinking, which may or may not have direct or indirect climate crisis-reversing capabilities. The most well-known example is using technology to remove carbon dioxide from the atmosphere. While the planet absorbs it naturally, people are trying to find ways to accomplish it faster or more efficiently.

Geoengineers focus on identifying natural processes that are suffering, such as rainfall or plant growth, and attempt to recreate or supplement them with electronic or mechanical techniques. 

This field is constantly developing and becoming more innovative because of machine learning and artificial intelligence. Yet, it does pose some controversy, which advocates are attempting to overcome.

What Are Examples of Geoengineering?

Geoengineering takes even more forms than the methods above, ranging in effectiveness and development. They encompass two primary methods.

The first is solar radiation management (SRM). As the atmosphere thins, the sun’s power is more impactful on the planet. If people can redirect and reflect sunlight into space, global warming and other changes would happen more slowly. This happens in multiple ways, including:

• Stratospheric aerosol injection (SAI): Putting materials like sulfur dioxide into the stratosphere for artificial cooling.
• Reflectors: Sending mirrors into space to deflect the sun’s rays.
• Surface albedo modification: Making surfaces on Earth more reflective, such as painting roofs white or enhancing ice caps to prevent heat penetration.
• Marine cloud brightening: Using saltwater makes low clouds above water more reflective.

The other technique is carbon dioxide removal, which takes many forms. You may be familiar with carbon capture and storage, a direct air capture technology. Other strategies include:

• Afforestation and reforestation: Planting trees to act as carbon sinks.
• Fertilizing oceans: Supplying nutrients to oceans to stabilize acidification and carbon absorption potential. It also stimulates phytoplankton growth, which is critical for balancing these ecosystems and preventing too much carbon from entering the water.
• Enhanced weathering: Encourages rocks to weather, as the process creates minerals that hold on to carbon dioxide longer.

Bioenergy: Burns organic matter to create energy, and carbon-capture equipment harnesses the by-product for reuse.

How Can Climate Hacking Be Good for the Planet?

Geoengineering has many theoretical advantages. Techniques like SAI are like rapid planetwide air conditioning. These advancements can calm global warming and natural disasters associated with heat waves.

The ability to control temperatures and their side effects protects the whole world and enhances safety for the most vulnerable areas. Targeted climate hacking can provide curated protection for communities or nations disproportionately affected by climate crises. This could strengthen climate equity and help countries overcome famine and drought.

Ultimately, geoengineering is just another tool in the arsenal against climate change. Humanity must diversify how it solves these problems — eliminating single-use plastics and using renewable energy is great, but it isn’t enough. 

The goal is to have as many solutions as possible, and climate hacking is a wonderful supplement to the long list of ways to fight climate change. It helps buy the planet time to develop and research more advanced and comprehensive techniques.

Why Is Geoengineering Contentious?

With all these benefits, how could there be any cons? Geoengineering technologies are still in the nascent stages, and experts don’t know the risks of deploying them globally. The planet could embrace these changes with only net-positive outcomes, or there could be consequences humanity couldn’t have predicted.

Additionally, there is little governance and oversight over this field. Climate hacking is new, and most countries do not prioritize establishing compliance. This leaves private companies to their own devices. Advocating for standardization and accountability is essential, but it may be too far off before unforeseen situations arise.

FAQs on Climate Hacking

What are some of the internet’s burning questions related to these topics?

What Is Another Word for Geoengineering?

Climate hacking is the most common alternative name. However, it is also called climate engineering, climate geoengineering, and climate intervention. All refer to similar concepts where humans attempt to execute planet-scale projects to better the planet.

Is Geoengineering Ethical?

Many question whether humans should invest their time and energy into these studies. The primary argument is that the technologies are early in development. They have little research behind them, and their long-term effectiveness remains unknown. Shifting focus away from immediately beneficial solutions, like electrification, concerns many activists. There are urgent issues, so is it worth diverting attention to climate hacking?

Additionally, the environmental and social risks of long-term geoengineering are still uncertain. It is not possible yet to know if excess saltwater dispersal or using carbon capture tech will have irreversible ramifications. However, people cannot find out these answers without taking risks. Is it worth it?

Finally, there is an assumption that humans could continue exploiting the planet because geoengineering can solve problems associated with human activity. Is it moral to see the Earth as something to manipulate to compensate for humanity’s poor decisions, instead of letting natural processes establish balance?

What Is an Example of Climate Vulnerability?

Climate change vulnerabilities refer to ecosystem alterations predisposed to being negatively affected. For example, the climate crisis could change an area’s humidity and temperature, making it more prone to wildfires or dust storms. Climate hacking attempts to prevent these vulnerabilities from becoming too severe. 

Fighting the Climate With Technology

Hacking the climate is one of many solutions for tackling sea level rise, global warming, and biodiversity loss. As it becomes more commonplace, its ethical issues and oversights should dissolve, leaving only the best and most effective technologies in humanity’s hands. Activists and experts should encourage the planet to restore itself naturally, but it may need some help from those destroying it to get there.
