Du sang français a coulé, et qu'a fait Nicolas Sarkozy, M. Thréard ? Il a envoyé ses deux lieutenants pour négocier avec un terroriste, condamné à perpétuité pour avoir tué 54 Français.

NEW: 2024 has just been confirmed as the warmest year on record, and the first to breach the 1.5C threshold.
We used a ridgeline (Joy Division inspired) chart to visualise daily temperature anomalies since 1940.
2024 clearly stands out with 100% of its days above 1.3C and 75% above 1.5C.
