Humans have establish it heavy to quit dodo fuels , which is why some contend that we ’ll soon need to start geoengineering — that is , modifying the atm to forbid catastrophic thaw of the planet .
The practice is controversial . Some debate it ’s the only solution given that we ’ve waited too long to reduce carbon emissions . Others say we should n’t be running two uncontrolled experiment on the Earth ’s climate ( the first being the world-wide burning of fossil fuel ) .
That has n’t stopped people from strain . And one approach championed byMake Sunsetshas drawn the aid of the U.S. Environmental Protection Agency .
The startup is basically two guys from Silicon Valley who have been turn weather balloons filled with hydrogen gas and sulfur dioxide particles . When the balloon swim somewhere past 66,000 understructure in altitude , it abound and releases the atomic number 16 dioxide particle , which scatter and mull sunlight , chill the Earth a lilliputian number .
The companionship sells “ cooling reference ” base on how much estimated warming each balloon release negates . Make Sunsets has raised $ 750,000 , according to PitchBook , and the inauguration says its investors include Boost VC , Draper Associates , and Pioneer Fund .
Neither founder is a scientist , but the skill behind sulfur dioxide and solar reflectivity is reasoned . Humansaccidentally provedthe importance of S dioxide in global albedo — the ordinary reflectivity of the Earth ’s surface — when they slashed the sulphur content of marine shipping fuel in 2020 ; one prominent mood scientist hasargued in favorof the practice .
Still , yield the complexness of the planetary mood , it ’s not clear what other effects the practice might have . It might sow rainstorm in one region while deprive other area of rain . Several scientists haveurged caution .

Plus , if sulfur dioxide particles drift nigher to land , they could aggravate people ’s bronchial asthma and cause other respiratory problems . Here , the EPA takes issue with Make Sunsets ’ overture to geoengineering . atomic number 16 dioxide is regulated as an air pollutant . EPA Administrator Lee Zeldin said this week that the representation isinvestigating the companionship .
Make Sunsets argues its action at law are effectual . In anFAQon its website , the society says , “ Yes , our method to cool Earth fall under the Weather Modification Act of 1976 and account annually to NOAA of our deployments as postulate . ”
The jurisprudence is muzzy here , though . When it was written , the Weather Modification Act was likely mean to cover the recitation of swarm seeding , in which particles like silver iodide are shot into clouds to induce rain or snow . Most conditions modification today is done by entities likeski resortsandirrigation districts in the West . It’snot clearhow the law applies to climate adjustment .
Still , while the EPA might be warrant in its probe , it is n’t precisely ordered with Zeldin ’s plan of attack to pollution .
The agency’sefforts to encourage coalare likely to father far more atomic number 16 dioxide contamination than Make Sunsets will release with its balloons . A Make Sunsets balloon released onNovember 15 , 2024 , release 1,715 grams of S dioxide . In 2023 , U.S. business leader plants released650,000 tonsinto the atmosphere , themajorityof which come from coal . That ’s or so the same amount as 343,900,000 of the startup ’s balloons .
