March 2023 recorded a temperature anomaly of 1.23°C, significantly exceeding the 60-point rolling average of 0.92°C by 2.7 standard deviations. This represents the highest reading in the dataset, breaking above the previous range of 0.64-1.09°C. The spike coincides with atmospheric CO₂ reaching 431.12 ppm (up 0.6% in 3 months) and occurs amid broader economic volatility—treasury yields jumping 10.6% while unemployment hits record lows. Statistically, a 2.7σ deviation suggests either a fundamental shift in the underlying temperature pattern or an exceptionally rare event. Worth monitoring whether this signals sustained elevation or returns to historical norms.
