Atmospheric CO₂ reached 431.12 ppm on April 15th, marking a 2.1 standard deviation spike above the recent mean of 421.17 ppm. This reading sits at the upper edge of the seasonal cycle peak we typically see in late spring. The timing aligns with concerning cross-series signals: global temperature anomaly jumped 9.3% over 3 months to 1.18°C above baseline. Historical data shows CO₂ concentrations have accelerated from ~315 ppm in 1958 to current levels - a 37% increase in 68 years. While seasonal variation explains some fluctuation, this deviation suggests we may be seeing faster accumulation than the ~2.5 ppm annual trend. Are we witnessing feedback loops amplifying emissions?
