Oxygen Availability

🟢 Baseline: Near Sea-Level Cities

(Almost no reduction in oxygen availability)

These cities are low enough that oxygen availability is effectively the same as sea level (difference <0.3%).

Reykjavík (~0–60 m)

Copenhagen (~1–14 m)

Bangkok (~1–2 m)

Shanghai (~4 m)

Berlin (~34 m)

Paris (~35 m)

Seoul (~38 m)

Tokyo (~40 m)

Istanbul (~40 m)

Los Angeles (~71 m avg)

Toronto (~76 m avg)

Estimated oxygen availability:
~99.7–100% of sea-level oxygen pressure
👉 Practically no physiological difference for most people.

🟡 Moderate Elevation (Noticeable but Mild Reduction)
Santiago (~520 m)

~94–95% of sea-level oxygen availability

~5–6% less oxygen per breath than sea level

Most healthy people barely notice this difference.

🟠 Higher Elevation (Clear but Still Mild Reduction)
Madrid (~667 m)

~92–93% of sea-level oxygen availability

~7–8% less oxygen per breath than sea level

Still mild — usually not noticeable unless exercising intensely.

🔴 Highest in Your List
São Paulo (~760 m)

~91–92% of sea-level oxygen availability

~8–9% less oxygen per breath than sea level

Among your listed cities, São Paulo has the lowest oxygen availability due to elevation — but it’s still considered low altitude medically.

mods airstrike him

im gonna rip it

For reference CN Kickoff occured at Guangzhou which is ~21m above sea level. Note Americas kickoff occurs at LA which is the highest out of any region at kickoff. Hence Americas team have the altitude advantage, if any non-Americas team want to win they need to adapt to the altitude fast
