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.
Ridgeline chart showing the distribution of global daily air temperature differences from the pre-industrial reference period (1850-1900), for every year between 1940 and 2024. Each individual year resembles a hill, shaded in a darker shade of red and further to the right for warmer years. The trend is clearly towards warmer years, with 2024 standing out as first year above 1.5C.

2023 was one of the worst years for wildfires in the EU in over two decades. 🔴 500,000 hectares of natural lands affected, 🔴 The largest single fire in the EU since tracking began, 🔴 ‘Megafires’ are on the rise and fire season prolonged. → europa.eu/!KyvRhh
A map of Europe titled "Wildfires in Europe 2023," showing wildfire activity as coloured dots of varying sizes to represent the area burned. Larger dots indicate larger areas burned: purple for ≥5000 hectares, red for 1000–5000 hectares, pink for 500–1000 hectares, orange for 100–500 hectares, and yellow for ≤100 hectares. High concentrations of wildfires are visible in southern Europe, particularly in Spain, Portugal, Italy, Greece, and Turkey, as well as parts of Eastern Europe and the Mediterranean region. Sparse activity is observed in northern Europe. The data is sourced from the European Forest Fire Information System (EFFIS).
