Climate Stripes Platform

The Problem

Climate science is complex, politically charged, and emotionally overwhelming. Most people can’t interpret IPCC reports, don’t trust abstract global averages, and tune out doom-laden narratives. Meanwhile, the iconic “warming stripes” visualization (colored bars showing temperature rise) resonates universally but remained static images, not interactive tools.

The communication gap: people need to see climate change in their context—their city, their lifetime, their decisions—not as distant polar bears or future catastrophes.

What I Built

A platform that transforms Prof. Ed Hawkins’ warming stripes from static images into interactive, location-specific climate communication tools:

Localized Climate Insights

• Users enter their location (city/region) and birth year
• Platform generates personalized warming stripes showing temperature changes during their lifetime
• Comparison views: “Your city vs. global average” “Your childhood vs. today”

Embed & Share Tools

• Generate custom warming stripes for organizations, events, or campaigns
• Embeddable widgets for news articles, NGO websites, and educational materials
• Social media templates with location-specific climate facts

Trend Projections

• “If current trends continue” visualizations for user’s location by 2050, 2100
• Integration with IPCC/NOAA datasets for scientific accuracy
• Explainer content contextualizing what temperature changes mean locally (agriculture, weather, seasons)

The Tech Stack

• Frontend: Next.js with D3.js for data visualization
• Data Sources: NOAA, Met Office Hadley Centre, Berkeley Earth datasets
• API: Node.js backend processing climate data and generating visualizations on-demand
• Caching: Redis for generated stripe images to reduce compute costs
• Hosting: Vercel Edge for global distribution

Lessons Learned

Personal Is Political (and Effective) Generic climate messaging gets ignored. “Earth is warming 1.2°C” doesn’t move people. “Your hometown warmed 2.3°C since you were born” creates emotional connection. We saw 3x higher social shares when visualizations were personalized vs. global. Lesson: make data personally relevant to break through apathy.

Simplicity Beats Sophistication Early prototypes included precipitation, extreme events, attribution science—overwhelming. Stripping back to just temperature (the warming stripes core) made the tool accessible. We added complexity behind optional “learn more” layers. Lesson: entry point must be stupid-simple; depth is opt-in.

Embeds Multiply Impact Most users never visited the site directly—they encountered warming stripes embedded in news articles (Guardian, BBC) or NGO campaigns. Building for embedding (lightweight widgets, flexible sizing, no branding requirements) unlocked 10x distribution. Lesson: your platform is infrastructure, not destination.

Data Accuracy Is Non-Negotiable Climate communication requires unimpeachable sources and transparent methodology. Using NOAA/Met Office data and citing sources in every visualization built credibility that let the tool cross political divides. Lesson: in contentious domains, methodology transparency is feature #1.

Open Licensing Enables Movement Releasing visualizations under Creative Commons (like original stripes) meant educators, activists, journalists could use freely. This “give away the commodity” approach built ubiquity and positioned warming stripes as climate communication standard. Lesson: some value is best captured by not capturing it.
