March 2002 temperature anomaly reached 0.88°C, significantly exceeding the 60-point rolling average of 0.49°C by 2.7 standard deviations. This represents the highest reading in the recent dataset, with temperatures showing steady acceleration from 0.25°C in January 2000. The spike coincides with atmospheric CO₂ at 431.12 ppm (up 0.6% over 3 months) and occurs during a period of economic expansion - unemployment at record lows and GDP growing 1.4% quarterly. This statistical outlier suggests we may be observing a phase shift in the temperature baseline rather than routine variation.
