Humans face significant challenges in transitioning away from fossil fuels, prompting discussions about the necessity of geoengineering—interventions aimed at modifying the climate to avert severe global warming. This method, however, is highly divisive. Some experts contend it may be our only option now that carbon emissions have risen unchecked. In contrast, others caution against initiating a second uncontrolled experiment with the Earth’s climate, especially after the extensive damage caused by fossil fuel consumption.
Despite the controversy, innovative attempts are being made. A startup called Make Sunsets, consisting of just two Silicon Valley entrepreneurs, has garnered attention for its unconventional geoengineering approach. The company has been sending weather balloons into the stratosphere, filled with hydrogen and sulfur dioxide particles. Once these balloons reach about 66,000 feet, they burst, releasing sulfur dioxide to reflect sunlight, theoretically reducing global temperatures.
Make Sunsets markets “cooling credits” based on the estimated warming mitigated by each balloon launch. The startup has attracted $750,000 in funding from investors like Boost VC and Draper Associates, despite neither founder having a scientific background. The concept of using sulfur dioxide to enhance solar reflectivity is founded on scientific principles, underscored by accidental evidence from reduced sulfur in marine fuels, which impacted the planet’s albedo.
However, the geoengineering method’s broader consequences remain uncertain. While it could potentially trigger rainfall in some areas, it might also deprive others of necessary precipitation—a dual-edged sword that has raised concerns among scientists advocating for caution. Additionally, if sulfur dioxide descends to lower altitudes, it may worsen respiratory conditions like asthma, prompting regulatory scrutiny from the U.S. Environmental Protection Agency (EPA).
The EPA, under Administrator Lee Zeldin, is currently investigating Make Sunsets’ activities, given that sulfur dioxide is classified as an air pollutant under U.S. law. Make Sunsets claims its operations comply with the Weather Modification Act of 1976, which was originally intended to regulate practices such as cloud seeding. However, the application of this law to geoengineering remains ambiguous.
While the EPA’s investigation appears justified, it is worth noting the irony in the agency’s stance towards pollution. Recent efforts to enhance coal production could result in far greater sulfur dioxide emissions than those generated by Make Sunset’s balloon releases. For instance, a single balloon release on November 15, 2024, emitted 1,715 grams of sulfur dioxide, whereas U.S. power plants released a staggering 650,000 tons in 2023, primarily from coal, equating to millions of times more than the startup’s activities.
This juxtaposition highlights a crucial debate: as we grapple with the climate crisis, how we balance innovation and regulation becomes ever more pivotal in shaping our environmental future.
