GaIA Echo
GaIA Echo is a forensic climate analysis platform powered by Claude Opus 4.7.
Core trick
Replays ERA5 reanalysis fields frame by frame with visible model reasoning, and perturbs the simulation by a temperature offset for counterfactuals.

Description
GaIA Echo is a forensic climate analysis platform powered by Claude Opus 4.7. Born from the DANA that struck my home city of Valencia on October 29, 2024—where 230 people died after early-warning protocols failed—I built this tool to make climate reasoning auditable and actionable, ensuring future warnings arrive on time.
The platform reconstructs five historical catastrophes from ERA5 reanalysis, narrated in real time with Opus 4.7's visible reasoning. A key emergent behavior is live self-correction: the model verifies data before asserting and corrects itself, citing sources.
Core features:
Counterfactual Engine: Perturbs simulations with ΔT shifts (e.g., +1.5°C).
Resident Guardian: Powered by Claude Managed Agents, it monitors NOAA SST data every 6 hours. Every briefing includes full audit trails (agent_id, session_id).
MCP Server: Exposes 5 tools and 3 resources, allowing any Claude Desktop user to query our ERA5 dataset natively.
Audience-Aware Output: Translates identical simulation data into 4 registers (public/student/researcher/emergency).
Built solo in four days. Live in production at https://echo.gaiapp.es

# 🌍 GaIA Echo ### When the DANA hit Valencia in October 2024, the early-warning protocols failed. 230 people died. > _GaIA Echo replays that catastrophe — and four others — frame by frame on real ERA5 reanalysis fields, with **Claude Opus 4.7's adaptive thinking visible** at every step. It is a climate-forensics cockpit where the model narrates what happened, audits its own answers when challenged, and never cites a number that did not come from data on disk._ 🔗 **Live demo:** <https://echo.gaiapp.es> 🏆 **Submission:** [Built with Opus 4.7 Hackathon](https://www.anthropic.com) · April 2026 🎬 **Demo video:** <https://www.youtube.com/watch?v=lRMluo9EVcM> **Three things to try in 60 seconds:** 1. Open **Forensic › DANA Valencia 2024**, scrub the timeline to phase 6, watch Opus reason over the convergence collapse. 2. Open **ECHO** (⌘/Ctrl+K) on any surface, ask *"¿Fue el DANA Valencia 2024 más fuerte que la peor hora de lluvia en Pakistán 2022?"* — when the model overstates, follow up *"¿estás seguro? revísalo"* and watch it emit a `### Correction` block instead of doubling down. 3. Open this repo in **Claude Code** — two bundled [Skills](#-use-with-claude-code--bundled-skills) load automatically and let any agent answer quantitative forensic questions or author NOAA-CPC-style ENSO briefings without inventing a single number. --- ## 🎯 What is GaIA Echo? Climate science speaks in NetCDF, ERA5 grids and Hovmöller diagrams. The public speaks in headlines. **GaIA Echo collap
