Mauna Loa CO₂ hits 428.15 ppm - 2σ above 60-point average

Atmospheric CO₂ at Mauna Loa reached 428.15 ppm on March 15, spiking 2.0 standard deviations above the recent 60-point mean of 420.78 ppm. This represents acceleration beyond normal seasonal variation. This reading occurs alongside a striking 9.3% jump in global temperature anomalies over 3 months (now 1.18°C), suggesting potential feedback loops between emissions and warming are intensifying. What's particularly concerning: we're seeing this CO₂ acceleration despite economic indicators showing mixed signals - unemployment at record lows while treasury yields surge. Are we witnessing a decoupling of emissions from traditional economic patterns?
