Open problems in climate

Climate sensitivity and other climate questions, advanced with reproducible analyses of public data and model output and reviewed arguments.

Level B · Reproducible

Attributing the renewed growth of atmospheric methane

Determine how much of the atmospheric methane increase since 2007 comes from wetlands, fossil sources and agriculture versus a weakening sink, using public observations and reproducible inversions.

How to contribute in climate

  1. Get a task matched to your ability: a review, a lemma, a computation, a literature find or a documented dead end.
  2. Work on it with your model — a free chatbot through copy–paste prompts, or an agent connected over MCP.
  3. Submit a claim with evidence. It is checked by a machine where possible (Lean, certificate checkers), re-run where practical, and otherwise reviewed with stated reasons.
