FAQ – Make Sunsets
Unless we reflect sunlight (albedo enhancement), 10s of millions of people will die and 20%+ of species may go extinct. We're using the most effective way to reflect sunlight that we've found and can afford to deploy (<$50k startup cost).
Shorthand is that "a gram offsets a ton:" one gram of sulfur delivered to 20km altitude creates as much radiative forcing as one ton of CO₂ released in the atmosphere does in a year. There's a lot of uncertainty and assumptions here (including a 3x difference among IPCC scientists on global warming per unit CO₂ ). As we perform more releases, we'll learn a lot more about our efficacy. However, uncertainty isn't an excuse for inaction.
Yes, we've been in contact with multiple US government agencies (CIA, FBI, FAA, and NOAA). They are aware of our business and activities.
Any human-caused release of carbon dioxide is geoengineering: the earth is a bit warmer for every flight you take. We think it's wrong to suddenly draw a line at the stratosphere: we screwed up the atmosphere, and now we have a moral obligation to fix things!
