On Tuesday, Make Sunsets announced it had completed three balloon launches near Reno, Nevada, each of which contained less than 10 grams of sulfur dioxide, which is the most commonly sited aerosol particle discussed in conversations about solar geoengineering. Two of the balloons launched also had location trackers, and one had a camera, too.
The idea of solar geoengineering has been around for decades and generally refers to spraying aerosol particles into the upper atmosphere in order to reflect the sun’s rays away from earth and back to space, cooling the earth and temporarily mitigating the effects of climate change.
Essentially, solar geoengineering is mimicking what happens when a volcano erupts, and it’s known to work. When Mount Pinatubo in the Philippines released thousands of tons of sulfur dioxide into the stratosphere in the 1991 eruption, the global temperature of the earth was lowered on average by about 1 degree Fahrenheit, according to the U.S. Geological Survey.
Solar geoengineering is not a solution to climate change, and nobody who studies it rigorously suggests it should be. It’s a temporary stopgap measure.
In addition, while releasing sulfur dioxide particles will cool the earth quickly and relatively inexpensively, it’s also dangerous. Injecting sulfur dioxide into the atmosphere could damage the ozone layer, cause respiratory illness and create acid rain.
But as the effects of climate change become more obvious, people are beginning to take the idea more seriously.
The White House is coordinating a five-year research plan into solar geoengineering, the quadrennial U.N.-backed Montreal Protocol assessment report included an entire chapter addressing stratospheric aerosol injection (more colloquially called solar geoengineering), and Dustin Moskovitz, a co-founder of Facebook, is funding solar geoengineering research via his philanthropic organization, Open Philanthropy.
While momentum is building, there isn’t any international governance rules about how to study and potentially regulate the idea.
Luke Iseman, a serial inventor and the former director of hardware at Y Combinator, launched Make Sunsets in October in an effort to push that envelope. San Mateo-headquartered venture capital firm BoostVC invested $500,000 in the startup and Iseman brought in a co-founder, Andrew Song.
The launches in Nevada earlier in February occurred at the Rancho San Rafael Regional Park in Reno, , where an annual hot-air balloon festival takes place, Iseman told CNBC.
They chose Nevada “because it’s in the U.S., we’re very confident we know and followed all applicable rules, know the terrain well from past adventures, and, we didn’t want to interfere with a friend’s efforts to get a marine cloud brightening project permitted in California,” Iseman told CNBC.
The Nevada launch was previously detailed by Time reporters, who were there. It was a shoe-string MacGyver-ed event orchestrated out of a hotel room, with a grill and weather balloon equipment. But, as evidenced by the images embedded below, shared with CNBC by Make Sunsets, the balloons lifted off.

Iseman has both idealistic and practical goals.
“Most importantly: We need to cool earth to save millions of lives, hundreds of thousands of species, and buy the time we need to decarbonize,” Iseman told CNBC.
To make the business sustainable, Make Sunsets is selling cooling credits, which gives companies and individuals a way to offset the effects of their carbon emissions. But the startup has yet to deliver.
“We have 2,790 cooling credits ordered by 58 paying customers that we haven’t yet delivered,” Iseman told CNBC. “On one hand, we’re working hard on a controversial project to cool earth. On the other, we’re a startup with the same basic challenge as any other: get customers to pay more for what we’re selling than it costs to make it.”
Make Sunsets said it made the FAA aware that it was releasing a balloon.
The FAA provided the following statement: “The FAA has comprehensive regulations for safely operating unmanned free balloons. Among other things, the regulations require the balloon to be equipped so it can be tracked by radar, and the operator to notify the FAA prior to and at the time of launch, monitor and record the balloon’s course, make position reports to the FAA as requested, and notify the FAA when the balloon begins its descent and its expected trajectory.”
Correction: A previous version of this story misstated what the balloons contained. All three of them had sulfur dioxide.

Amazon on Thursday announced Prime members can access new fixed pricing for treatment of conditions like erectile dysfunction and men’s hair loss, its latest effort to compete with other direct-to-consumer marketplaces such as Hims & Hers Health and Ro.
Shares of Hims & Hers fell as much as 17% on Thursday, on pace for its worst day.
Amazon said in a blog post that Prime members can see the cost of a telehealth visit and their desired treatment before they decide to proceed with care for five common issues. Patients can access treatment for anti-aging skin care starting at $10 a month; motion sickness for $2 per use; erectile dysfunction at $19 a month; eyelash growth at $43 a month, and men’s hair loss for $16 a month by using Amazon’s savings benefit Prime Rx at checkout.
Amazon acquired primary care provider One Medical for roughly $3.9 billion in July 2022, and Thursday’s announcement builds on its existing pay-per-visit telehealth offering. Video visits through the service cost $49, and messaging visits cost $29 where available. Users can get treatment for more than 30 common conditions, including sinus infection and pink eye.
Medications filled through Amazon Pharmacy are eligible for discounted pricing and will be delivered to patients’ doors in standard Amazon packaging. Prime members will pay for the consultation and medication, but there are no additional fees, the blog post said.
Amazon has been trying to break into the lucrative health-care sector for years. The company launched its own online pharmacy in 2020 following its acquisition of PillPack in 2018. Amazon introduced, and later shuttered, a telehealth service called Amazon Care, as well as a line of health and wellness devices.
The company has also discontinued a secretive effort to develop an at-home fertility tracker, CNBC reported Wednesday.
Former U.S. Army intelligence analyst Chelsea Manning says censorship is still “a dominant threat,” advocating for a more decentralized internet to help better protect individuals online.
Her comments come amid ongoing tension linked to online safety rules, with some tech executives recently seeking to push back over content moderation concerns.
Speaking to CNBC’s Karen Tso at the Web Summit tech conference in Lisbon, Portugal, on Wednesday, Manning said that one way to ensure online privacy could be “decentralized identification,” which gives individuals the ability to control their own data.
“Censorship is a dominant threat. I think that it is a question of who’s doing the censoring, and what the purpose is — and also censorship in the 21st century is more about whether or not you’re boosted through like an algorithm, and how the fine-tuning of that seems to work,” Manning said.
“I think that social media and the monopolies of social media have sort of gotten us used to the fact that certain things that drive engagement will be attractive,” she added.
“One of the ways that we can sort of countervail that is to go back to the more decentralized and distribute the internet of the early ’90s, but make that available to more people.”
Nym Technologies Chief Security Officer Chelsea Manning at a press conference held with Nym Technologies CEO Harry Halpin in the Media Village to present NymVPN during the second day of Web Summit on November 13, 2024 in Lisbon, Portugal.
Asked how tech companies could make money in such a scenario, Manning said there would have to be “a better social contract” put in place to determine how information is shared and accessed.
“One of the things about distributed or decentralized identification is that through encryption you’re able to sort of check the box yourself, instead of having to depend on the company to provide you with a check box or an accept here, you’re making that decision from a technical perspective,” Manning said.
‘No longer secrecy versus transparency’
Manning, who works as a security consultant at Nym Technologies, a company that specializes in online privacy and security, was convicted of espionage and other charges at a court-martial in 2013 for leaking a trove of secret military files to online media publisher WikiLeaks.
She was sentenced to 35 years in prison, but was later released in 2017, when former U.S. President Barack Obama commuted her sentence.
Asked to what extent the environment has changed for whistleblowers today, Manning said, “We’re at an interesting time because information is everywhere. We have more information than ever.”
She added, “Countries and governments no longer seem to invest the same amount of time and effort in hiding information and keeping secrets. What countries seem to be doing now is they seem to be spending more time and energy spreading misinformation and disinformation.”
Manning said the challenge for whistleblowers now is to sort through the information to understand what is verifiable and authentic.
“It’s no longer secrecy versus transparency,” she added.
LISBON, Portugal — British online lender Zopa is on track to double profits and increase annual revenue by more than a third this year amid bumper demand for its banking services, the company’s CEO told CNBC.
Zopa posted revenues of £222 million ($281.7 million) in 2023 and is expecting to cross the £300 million revenue milestone this year — that would mark a 35% annual jump.
The 2024 estimates are based on unaudited internal figures.
The firm also says it is on track to increase pre-tax profits twofold in 2024, after hitting £15.8 million last year.
Zopa, a regulated bank that is backed by Japanese giant SoftBank, has plans to venture into the world of current accounts next year as it looks to focus more on new products.
The company currently offers credit cards, personal loans and savings accounts that it offers through a mobile app — similar to other digital banks such as Monzo and Revolut which don’t operate physical branches.
“The business is doing really well. In 2024, we’ve hit or exceeded the plans across all metrics,” CEO Jaidev Janardana told CNBC in an interview Wednesday.
He said the strong performance is coming off the back of gradually improving sentiment in the U.K. economy, where Zopa operates exclusively.
Commenting on Britain’s macroeconomic conditions, Janardana said, “While it has been a rough few years, in terms of consumers, they have continued to feel the pain slightly less this year than last year.”
The market is “still tight,” he noted, adding that fintech offerings such as Zopa’s — which typically provide higher savings rates than high-street banks — become “more important” during such times.
“The proposition has become more relevant, and while it’s tight for customers, we have had to be much more constrained in terms of who we can lend to,” he said, adding that Zopa has still been able to grow despite that.
A big priority for the business going forward is product, Janardana said. The firm is developing a current account product which would allow users to spend and manage their money more easily, in a similar fashion to mainstream banking providers like HSBC and Barclays, as well as fintech upstarts such as Monzo.
“We believe that there is more that the consumer can have in the current account space,” Janardana said. “We expect that we will launch our current account with the general public sometime next year.”
Janardana said consumers can expect a “slick” experience from Zopa’s current account offering, including the ability to view and manage multiple account bank accounts from one interface and access to competitive savings rates.
IPO ‘not top of mind’
Zopa is one of many fintech companies that has been viewed as a potential IPO candidate. Around two years ago, the firm said that it was planning to go public, but later decided to put those plans on ice, as high interest rates battered technology stocks and the IPO market froze over in 2022.
Janardana said he doesn’t envision a public listing as an immediate priority, but noted he sees signs pointing toward a more favorable U.S. IPO market next year.
That should mean that Europe becomes more open to IPOs happening later in 2026, according to Janardana. He didn’t disclose where Zopa would end up going public.
“To be honest, it’s not the top of mind for me,” Janardana told CNBC. “I think we continue to be lucky to have supportive and long-term shareholders who support future growth as well.”
Last year, Zopa made two senior hires, appointing Peter Donlon, ex-chief technology officer at online card retailer Moonpig, as its own CTO. The firm also hired Kate Erb, a chartered accountant from KPMG, as its chief operating officer.
The company raised $300 million in a funding round led by Japanese tech investor SoftBank in 2021 and was last valued by investors at $1 billion.
