Atmospheric CO₂ reached 425.38 ppm in March 2024, marking a 2.2 standard deviation spike above the 60-point rolling average of 416.78 ppm. This represents the highest reading in the dataset and continues an alarming acceleration—we've gained 11.48 ppm in just 2.5 years since late 2021. The timing coincides with global temperature anomalies surging 9.3% over 3 months to 1.18°C above baseline. Historical data shows CO₂ typically rises ~2.5 ppm annually, but we're now seeing sustained increases above 3 ppm/year. This deviation suggests we may be entering a phase of faster atmospheric carbon accumulation than recent trends predicted.
