Climate signal ledger

Brief

Create a reproducible artifact that another learner can inspect without access to your private workspace. State the question, choose a bounded source set, document decisions, and preserve failed checks alongside the final result.

Concepts in transfer

Change and accumulation — See derivatives and integrals as two views of how local change builds a whole.

Probability as evidence — Use distributions to reason about uncertainty without pretending it disappears.

Rubric

• The system boundary and assumptions are explicit.
• Every external claim has a source record.
• Deterministic checks can be repeated.
• Limitations describe a real failure regime.
• The final explanation distinguishes observation from inference.

Responsibility record

This is an open project prompt, not a grade, certificate, or credential. A synced private workspace will remain learner-owned; public sharing is always an explicit separate action.
