Where the curve breaks
The frontier is gentle until it isn't. Going from La Rochelle (39.5 kg, 18.7 °C) to Bordeaux (251 kg, 18.9 °C) buys 0.2 °C more warmth for an extra 212 kg — 1058 kg of CO₂e per degree. That single step is the most expensive warmth on the whole curve.
The pick of them
If you'd rather have sunshine than heat
