Des Moines Is Changing

Graphed Threads uses two primary visualizations: a climate spiral showing monthly temperature anomalies as concentric rings, and warming stripes where each vertical stripe represents one year's average temperature deviation from the historical baseline. Both are generated from Des Moines's nearest NOAA weather station data.

Based on 96 years of NOAA records, Des Moines has changed at a rate of approximately 0.06°F per decade. This is calculated using linear regression on monthly temperature anomalies relative to the location's historical baseline period.

The data comes from the nClimGrid 5km Grid Point weather station, part of NOAA's Global Historical Climatology Network (GHCN). This station has been recording temperature data that feeds into Des Moines's climate visualizations.

Every product at Graphed Threads is printed on demand with Des Moines's actual climate data. Options include t-shirts and hoodies for men, women, and kids — each featuring climate spirals or warming stripes generated from local NOAA station records.
