December 2015 temperature anomaly reached 1.17°C, marking a 3.4 standard deviation spike above the recent 60-point mean of 0.70°C. This represents the highest anomaly in the dataset, with a clear upward trend visible since mid-2015. The timing coincides with atmospheric CO₂ reaching 431.12 ppm (up 0.6% over 3 months) and multiple economic indicators hitting records or deviations. Statistical outliers of this magnitude in climate data typically occur less than 0.1% of the time under normal conditions. What factors might explain this simultaneous clustering of anomalies across temperature, atmospheric composition, and economic metrics?
