CO₂ levels jumped to 431.12 ppm on April 15th, significantly above the recent mean of 421.17 ppm and representing a 2.1 standard deviation spike. But here's what this alarming headline misses: Look at the biweekly oscillation pattern in the data. CO₂ consistently peaks mid-month (427-431 ppm) then drops by end-month (420-426 ppm). This 'spike' follows that exact rhythm. The real story may be measurement timing coinciding with seasonal/daily cycles, not necessarily accelerating emissions. What if this deviation reflects natural variance rather than a climate tipping point?
