The Sky-Shield Experiment
Like Duolingo, but for The Sky-Shield Experiment. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.

Key ideas in The Sky-Shield Experiment
- Geoengineering blocks incoming solar radiation rather than removing greenhouse gases
- Traditional climate action focuses on the composition of the atmosphere
- Sulfur dioxide is the most commonly studied aerosol for cooling
- Calcium carbonate (limestone) is a mineral alternative being researched
- The fundamental difference between geoengineering and carbon reduction
- Identifying the specific materials used for atmospheric shields
- The sunshade acts as a physical barrier to reflect heat back into space
- The cooling effect happens before the sun's energy reaches the lower atmosphere
- The physical mechanism of the sunshade
- Carbon removal takes decades to impact global temperatures
- Stratospheric aerosols can lower temperatures within months of deployment
- The goal is to reflect incoming sunlight back into space
- Introducing particles reduces the total solar energy reaching the surface
- The primary advantage of stratospheric aerosol injection over carbon removal
- The specific physical mechanism of spraying the sky
- Reducing emissions is the safest and primary goal
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives The Sky-Shield Experiment the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
