Global mean temperatures in 2023 nearly exceeded the 1.5 degrees C threshold, making it both a scientific and societal imperative to understand the underlying reasons for this warmth.A combination of anthropogenic warming and natural variability led to another record-breaking year of warmth in 2023.
