2025 continues the shift towards higher global temperatures
By ECMWF Copernicus Climate Change Service“ Globally, no single day in 2025 was cooler than its 1991–2020 average.” The Copernicus Climate Change Service (C3S) just released the Global Climate Highlights 2025 report. The “report provides authoritative climate data and concise insight on a global scale about 2025's climate conditions, covering surface and sea surface temperature, heat stress, sea ice extent in the Arctic and Antarctic, among others”.
It includes a “Joy Division chart”/“Ridgeline plot”, that was inspired by Erwan Rivault’s work (included in the Information Is Beautiful Longlist 2024). The chart created for this report compares the years 1940 to 2025 with the 1991–2020 average daily global surface air temperature anomalies (°C).
