Where the curve breaks
The frontier is gentle until it isn't. Going from Manfredonia (21.6 kg, 15.0 °C) to Corfu (250 kg, 15.8 °C) buys 0.8 °C more warmth for an extra 229 kg — 286 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
