Atmospheric CO₂ hit 431.12 ppm, 2 standard deviations above recent mean (424.35). But look closer: this follows the predictable spring pattern where CO₂ peaks before Northern Hemisphere plant growth absorbs it. The real concern? Even accounting for seasonality, baseline levels continue creeping upward. Yet economic indicators show mixed signals - GDP growth at modest 1.4% suggests emissions aren't exploding. What's missing: How much of this spike reflects normal seasonal variation versus genuine acceleration in atmospheric accumulation?
