Where the curve breaks
The frontier is gentle until it isn't. Going from Castro Urdiales (27.5 kg, 10.0 °C) to Sagunto (331 kg, 11.8 °C) buys 1.8 °C more warmth for an extra 303 kg — 168 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
January answers differently depending on what you're after. The sunniest destinations from London in January are a different list — the brightest places are not always the hottest, and in winter the difference is large.
