Biodome Experiment Setup

• Kurtis Baute sealed himself inside homemade airtight biodome 8+ hours ago
• Cube dimensions: 10ft x 10ft x 10ft
• Air volume: ~30,000 litres
• Safety equipment: O2/CO2 sensors, gas monitors, blood monitors, paramedic onsite
• Purpose: video series on human-air interaction
• Warning: Do not try at home

Historical CO2 Levels

• 60 years ago: atmospheric CO2 ~300 ppm
• Modern natural landscapes: ~400 ppm (due to industrialization/fossil fuels)
• Urban environments: ~500 ppm
• Indoor poorly-ventilated spaces: up to 1,000 ppm

Cognitive Function Impact Research

• Office employees tested at different CO2 levels
• 1,000 ppm: 15% decrease in cognitive function
• School study (Texas, Idaho, Washington):
  • 50%+ classrooms exceeded 1,000 ppm
  • 1,400 ppm: 50% decrease in cognitive function
• 2,000 ppm side effects: nausea, loss of attention, headaches, sleepiness, poor concentration, increased heart rate, slight nausea

Current Experiment Status

• Current level in biodome: 6,370 ppm (later 6,500 ppm)
• Physical effects experienced: thick air sensation, brain fog, multiple video takes needed
• Bedrooms/cars frequently reach 4,000 ppm

Dangerous Levels

• 10,000 ppm: unsafe for 8-hour work exposure, long-term health concerns
• Motorcycle helmets often reach 10,000 ppm
• 30,000 ppm: extremely dangerous, potentially deadly

Future Projections & Solutions

• Bad news: CO2 levels projected to reach 695 ppm by end of century
  • Could result in 10-16% global cognitive function decrease
• Good news: actionable solutions available
  • Open windows in offices
  • Add plants to homes
  • Maintain/update HVAC systems
  • Use cognitive surplus to address climate change
