[heatmap-stripes-climate] Climate Warming Stripes

[MarkusNeusinger]

Description

Climate stripes (warming stripes) display temperature anomaly data as a sequence of vertical colored bars, one per year, using a blue-to-red diverging colormap. Created by Ed Hawkins, this minimalist visualization powerfully communicates long-term warming trends without axes, numbers, or labels.

Applications

• Communicating climate change to general audiences
• Showing long-term temperature trends for any location
• Environmental reporting and science communication
• Educational materials on global warming

Data

• year (integer) — year (e.g., 1850-2024)
• anomaly (numeric) — temperature anomaly in °C relative to baseline
• Size: 100-175 years

Notes

• No axes, no labels, no gridlines — pure data visualization
• Use blue (#08306b) to red (#67000d) diverging colormap centered at 0
• Each bar fills equal width, no gaps between bars
• Aspect ratio approximately 3:1 (wide and short)

✅ Spec ID: stripe-warming

Rationale: Climate warming stripes are a distinct, well-known minimalist visualization (Ed Hawkins) — no existing spec covers this type. Uses "stripe" as the plot type since this is an established data-viz form.

Add label approved to begin generation.

✅ Spec ID: heatmap-warming-stripes

Rationale: Climate warming stripes are a well-known minimalist visualization (created by Ed Hawkins) that encodes temperature anomalies as a 1D color-mapped heatmap — the heatmap base type with warming-stripes variant captures both its visual form and specific purpose.

No duplicates found among existing specs. The closest specs (heatmap-basic, heatmap-calendar) serve different visualization purposes.

Add label approved to begin generation.

✅ Spec ID: heatmap-stripes-climate

Rationale: Climate warming stripes are a 1D heatmap visualization using diverging color-mapped vertical bars to show temperature anomalies over time — a unique and widely recognized chart type created by Ed Hawkins.

Add label approved to begin generation.
