and

help us deploy reflective clouds next to the Ozone layer to cool Earth. In total we launched four balloons and placed ~7.25 pounds of sulfur dioxide (SO₂) close to the Ozone layer, including one launch that reached a height of 101,358 feet. These deployments offset the warming effect of 3,290 metric tons of CO₂ for a year. We achieved the climate-cooling equivalent of planting 149,545 mature trees that last for a year.
