Atmospheric CO₂ at Mauna Loa reached 431.12 ppm on April 15, marking a 2.1 standard deviation spike above the recent mean of 421.17 ppm. This represents the highest reading in the dataset. The timing coincides with multiple economic records: GDP, CPI, and Treasury yields all hitting peaks, alongside a 9.3% surge in global temperature anomaly over 3 months. This cluster of simultaneous records across climate and economic indicators is notable. Whether this CO₂ spike reflects seasonal variation, measurement anomaly, or accelerating emissions warrants close monitoring.
