The thing is : the first half of 2023 averaged 1.30°C, and the second half 1.67°C. So in a way, the first half of 2023 belongs more to the "previous regime" 2015-2023. Since July 2023, the anomaly averages 1.57°C, way above the 1.5 threshold. Unlikely future temps will bring it back down under 1.5°C
