The 10 warmest places within 15 hours of Dublin
Ranked on warmth in May alone, among well-known places (a Wikivoyage travel guide and at least 40,000 Wikipedia readers a year), one per area and at most three per country. The carbon is shown, not used to choose: the list further down is the other question, how much warmth each extra kilogram buys.

The low-carbon trade-off
The warmest place you can reach from Dublin in May within 15 hours is Edfu, 31.4 °C, costing 1,058 kg CO₂e return. The lowest-carbon option is Omagh at 39.4 kg — 27× less carbon, for 19.2 degrees less warmth.
Every destination here is on the efficiency frontier: nowhere else this site covers is both warmer in May and lower in carbon. Anything a better option beats outright has been left out.

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 Zagora (643 kg, 27.6 °C) to Assiut (989 kg, 29.0 °C) buys 1.4 °C more warmth for an extra 345 kg — 247 kg of CO₂e per degree. That single step is the most expensive warmth on the whole curve.

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.
