ChescoWx Posted 20 hours ago Share Posted 20 hours ago The above data is like most other places sufferring from NCEI altered temperatures which as is usually the case warms the past and chills the current. Below is actual vs altered data for beautiful Yellow Medicine County!! The graph shows 1895–2025: the NCEI adjusted line is in red and the raw station data in blue, each with its trend line. The trend is +0.19°F/decade for NCEI and +0.12°F/decade for raw, so NCEI shows about 60% more warming than the raw data - call me stunned!!

Increases in both high and low temperatures are to blame. Nope! The raw September trend for 1895–2025 is +0.13°F per decade, and it is not statistically significant (p ≈ 0.10; 95% range −0.03 to +0.29°F per decade). Series °F/decade 95% range p Raw September, 1895–2025 +0.13 ±0.16 0.10, not significant Link to comment Share on other sites More sharing options...
