Global Temperature Anomaly vs Sunspot Number
Global Temperature Anomaly and Sunspot Number correlate at r = +0.00 over 176 years (1850–2025), p = 0.969. With the time trend removed, r = -0.07. Not statistically significant.
Verdict: Not statistically significant. With n = 176, this correlation isn't statistically significant (p = 0.969). It could easily be chance.
