Where the curve breaks

The frontier is gentle until it isn't. Going from Shkoder (286 kg, 19.3 °C) to Chios (400 kg, 20.1 °C) buys 0.8 °C more warmth for an extra 115 kg — 143 kg of CO₂e per degree. That single step is the most expensive warmth on the whole curve.

The same month, asked differently

May answers differently depending on what you are after, and the lists genuinely diverge: the brightest places are not the hottest, and in summer the useful question stops being where is warm at all.
