CARDS: Climate Contrarianism Claim Detection
We build and release models that detect and classify 100+ types of climate contrarianism claims in text, based on the peer-reviewed CARDS taxonomy:

Ollama (one-line install)
ollama run exec3ds/cards-qwen3.5 # 4B default
ollama run exec3ds/cards-qwen3.5:9b
ollama run exec3ds/cards-qwen3.5:27b
Quick start
Just give it text — the system prompt and chain-of-thought reasoning are built in:
ollama run exec3ds/cards-qwen3.5 "CO2 is just a trace gas. The sun drives climate."
