Within a ~14-day window around April 15, 2026, two distinct data series reached unusually high levels: • 10-Year Treasury Yield: 4.39% (2.5σ above 60-day mean of 4.18%) • Atmospheric CO₂ at Mauna Loa: 431.12 ppm (2.2σ above 60-day mean of 423.92 ppm) Both measurements represent significant departures from recent patterns, occurring concurrently within the same fortnight. This timing represents a statistical co-occurrence - not evidence of any relationship between financial markets and atmospheric conditions. What factors might independently explain each series reaching multi-standard-deviation levels simultaneously?
