Climate Risk Brief Summarizer

How Climate Risk Brief Summarizer works

Press Load model once: your browser downloads Gemma 4 E2B instruction-tuned (web build) (2.0 GB) from this site and keeps it in its cache. Then add your text and press Summarize locally. The model runs on this device using your graphics card, so nothing you enter is sent to a server. Until the model is loaded, or if your device cannot run it, the tool falls back to a simple keyword check and labels the result as the fallback.

Gemma 4 E2B instruction-tuned (web build) is a small open language model from Google. The tool sends it the instruction below plus your text, asks for a JSON answer with fixed fields, and shows each field as a card. It runs at temperature 0, so the same input gives the same answer on the same device, though different graphics cards can word it slightly differently.

Inputs longer than 6,000 characters are cut to that length before they reach the model, and the result says so. The model only sees what you paste: it does not look anything up.

The instruction the model gets

You summarise a climate risk brief for a property or site. Group the hazards it mentions, copy every figure, year and zone exactly as written, and list preparedness gaps the brief itself points to. Do not estimate probabilities, costs or damage, and do not add hazards the brief does not mention.

What it returns

• Summary: Two plain sentences on the main exposures.
• Hazards: Each hazard (flood, heat, wildfire, smoke, wind, drought and so on) with the brief's evidence in brackets.
• Figures cited: Every number, zone, year or percentage, as written, with what it refers to.
• Preparedness gaps: Missing protections or plans the brief mentions, such as no backup power or no evacuation plan.

Worked example

The model's output for the built-in sample, recorded on a desktop browser. Your run may word things slightly differently.

Risk brief: Site is in FEMA zone AE, past basement flooding in 2019, wildfire smoke days increasing, backup power absent, insurance premium up 22%.

Summary

The site is exposed to flood risk and wildfire smoke events. There is a lack of backup power and an increase in insurance premiums.

The model

The files are served from this site, versioned so a cached copy is never stale. Nothing is fetched from a third party while you use the tool.

Limitations

• Small language models make mistakes: they can miss an item, merge two, or state something more confidently than the text supports. Check the result against your input before you rely on it.
• It needs WebGPU and about 8 GB of memory, so it is offered on desktops and laptops, not on phones and tablets. Devices that cannot run it get the keyword fallback, clearly labelled.
• Results describe the input you gave, not the real-world situation behind it. Review them yourself before acting.

Good uses

• Triage climate and sustainability notes before deeper review
• Prepare consistent labels for repeat workflows
• Reduce manual sorting on small batches
• Keep sensitive drafts in the browser preview
