Microsoft’s billionaire founder Bill Gates is financially backing the development of sun-dimming technology that would potentially reflect sunlight out of Earth’s atmosphere, triggering a global cooling effect. The Stratospheric Controlled Perturbation Experiment (SCoPEx), launched by Harvard University scientists, aims to examine this solution by spraying non-toxic calcium carbonate (CaCO3) dust into the atmosphere — a sun-reflecting aerosol that may offset the effects of global warming.
Widespread research into the efficacy of solar geoengineering has been stalled for years due to controversy. Opponents believe such science comes with unpredictable risks, including extreme shifts in weather patterns not dissimilar to warming trends we are already witnessing. Environmentalists similarly fear that a dramatic shift in mitigation strategy will be treated as a green light to continue emitting greenhouse gases with little to no changes in current consumption and production patterns.
SCoPEx will take a small step in its early research this June near the town of Kiruna, Sweden, where the Swedish Space Corporation has agreed to help launch a balloon carrying scientific equipment 12 miles (20 km) high. The launch will not release any stratospheric aerosols. Rather, it will serve as a test to maneuver the balloon and examine communications and operational systems. If successful, this could be a step towards a second experimental stage that would release a small amount of CaCO3 dust into the atmosphere.
David Keith, a professor of applied physics and public policy at Harvard University, recognizes the “very many real concerns” of geoengineering. It is true that no one knows what will happen until the CaCO3 is released and then studied afterward. Keith and fellow SCoPEx scientists published a paper in 2017 suggesting that the dust may actually replenish the ozone layer by reacting with ozone-destroying molecules. “Further research on this and similar methods could lead to reductions in risks and improved efficacy of solar geoengineering methods,” write the authors of the paper.
The exact amount of CaCO3 needed to cool the planet is unknown, and SCoPEx scientists similarly cannot confirm whether it is the best stratospheric aerosol for the job. Early research suggests that the substance has “near-ideal optical properties” that would allow it to absorb far less radiation that sulfate aerosols, causing significantly less stratospheric heating. This is the purpose of the experiment: once a safe, experimental amount of CaCO3 is released, the balloon will fly through it, sampling atmospheric reactions and recording resulting dynamics. Frank Keutsch, the project’s principal investigator, does not know what the results might bring. The perfect aerosol would not immediately tamper with stratospheric chemistry at all: “The only thing it would do is scatter maximum sunlight and hence cool down the planet.”
Proponents of geoengineering have cited the global cooling effects of volcanic eruptions that result from the introduction of sulfuric ash into the atmosphere. The 1815 eruption of Mount Tambora in Indonesia resulted in the “year without a summer,” while the 1991 eruption of Mount Pinatubo in the Philippines lowered global average temperatures by 0.5° C. Deliberate introduction of similar particles could potentially counter decades of greenhouse gas emissions. A report by the Intergovernmental Panel on Climate Change suggested the SCoPEx procedure could lower global temperatures by a full 1.5° C for no more than $1-10 billion a year.
Again, these temperature decreases bring with them serious risks. Freezing temperatures in 1815 led to failed crops in near-famine conditions. British scientists have cited stratospheric aerosols from volcanic eruptions in Alaska and Mexico as the potential cause of drought in Africa’s Sahel region. Major disruption of the global climate could bring unintended consequences, negatively impacting highly populated regions and engineering another refugee crisis.
David Keith has proposed the creation of a “risk pool” to compensate smaller nations for collateral damage caused by such tests, but such a payout might be little comfort to those displaced by unlivable conditions. The United States, Brazil, and Saudi Arabia blocked a 2019 United Nations assessment of global geoengineering plans. International cooperation will be required to assess the risks, winners, and losers of any such experiment, and how best to proceed with all in mind.
Considering the unknown risks attached to solar geoengineering, OECD members should continue in their efforts to develop economically attractive renewable energy technology, even as it supplements such efforts with limited and careful research and experimentation.

It sounds like a wacky idea out of science-fiction - but it’s funded in part by billionaire Microsoft founder Bill Gates and backed by top scientists at Harvard University. The researchers believe that a fleet of specially-designed aircraft could spray sulfate particles into the lower stratosphere to cool down our planet and offset the effects of climate change.
A test of the technology has been proposed for this year, the Daily Mail reports, with the Stratospheric Controlled Perturbation Experiment (SCoPEx) seeing a bag of carbonate dust released into the atmosphere 12 miles up. If that experiment proves successful, the researchers will move on to releasing the dust from planes.
The researchers suggest that jets flying 12 miles up would complete over 60,000 missions in 15 years, starting with a fleet of eight and moving up to 100 planes.
At present, there are no aircraft capable of doing this, so they would need to be developed. The Harvard researchers have claimed that, if it were launched this year, it would cost about $3.5 billion (£2.74 billion), plus $2.25 billion (£1.76 billion) per year.
The scientists said last year: ‘Dozens of countries would have both the expertise and the money to launch such a program.

The idea of ‘solar geo-engineering’ or solar radiation management (SRM) is controversial, mimicking the world-chilling effects of huge volcanic eruptions. Some scientists have suggested that such technology could be used as a ‘stop gap’ to reduce temperatures, while measures to limit CO2 emissions are put in place. But others have suggested that when the SRM was withdrawn, it could lead to rapid global warming in a phenomenon known as ‘termination shock’.

Uh...this is strange, that with Bill Gates being the biggest farmland owner in the United States. Umm, what is he trying to devise here?
