Recent Trend

PPM/Year (10yr)

Safe Limit (350 PPM): Exceeded ~1990, we are now in the climate danger zone
Point of No Return (450 PPM): Approaching in ~10-15 years at current rate, triggers irreversible tipping points
Pre-industrial: CO₂ was ~280 PPM for 10,000+ years before industrialization
Current Level: Now above PPM - causing record heat and extreme weather
Acceleration: Rate of increase has nearly doubled from 1960s to today
Indoor Risk: At 1,000+ PPM cognitive function declines - rising outdoor levels make indoor air harder to keep fresh
