🌡️ In the past decade, global average surface temperatures have consistently ranged about 0.9°C to 1.3°C above the 20th-century average (1901–2000 baseline), depending on the dataset used.
Major independent datasets all show this pattern:
•NASA (GISTEMP) reports recent years around ~1.1–1.3°C above the late-19th century baseline.
•NOAA shows similar anomalies relative to the 20th-century average.
•Copernicus Climate Change Service reports 2023 and 2024 exceeding ~1.4–1.5°C above pre-industrial levels in parts of the year.
It’s important to note:
•The 20th-century average baseline differs slightly from the pre-industrial (1850–1900) baseline often used in climate policy discussions.
•When compared to pre-industrial levels, recent global temperatures are roughly ~1.2–1.5°C warmer.
