Warm is not the same as pleasant, which is why sunshine and rainfall are shown alongside temperature. All three are ERA5 monthly means for 2023–2024.

Where the curve breaks

The frontier is gentle until it isn't. Going from Bolzano (13.2 kg, 10.5 h) to Genoa (18.7 kg, 10.7 h) buys 0.2 hours more sunshine for an extra 5.5 kg — 28 kg of CO₂e per hour. That single step is the most expensive sunshine on the whole curve.

The pick of them

If you'd rather have heat than sunshine
