The model’s verdict

The Transformer retrained from the notebook (the 2024 weights were never saved), shown three ways. The first is how the notebook evaluated it.

Notebook protocol

Dev claims predicted in batches of 16, in file order, from the 2024 retrieved evidence, as the notebook does.

Retrieved vs gold evidence

Gold passages were picked by the dataset’s annotators. Retrieved passages are what the TF-IDF rule returned from all 1.19M passages. Switch between the submitted 2024 output and the re-runs.

2024 submission

The passages the team actually retrieved and submitted in 2024 (their saved output file). The file records only passage ids, so scores are recomputed with the submission rule.

    Reducing black carbon emissions could help keep the climate system from passing the tipping points for abrupt climate changes, including significant sea-level rise from the melting of Greenland and/or Antarctic ice sheets.

  2. #2evidence-889770

    Andrew Dessler published a paper which found errors in Lindzen and Choi 2011, and concluded that the observations it had presented "are not in fundamental disagreement with mainstream climate models, nor do they provide evidence that clouds are causing climate change.

    In 1995 the Intergovernmental Panel on Climate Change (IPCC) issued a report reflecting the scientific consensus that the balance of evidence suggests there is a discernible human influence on global climate.

    The Intergovernmental Panel on Climate Change (IPCC) assessed the scientific literature on climate engineering (referred to as "geoengineering" in its reports), in which it considered carbon dioxide removal and solar radiation separately.

    The Geological Society of America (GSA) concurs with assessments by the National Academies of Science (2005), the National Research Council (2006), and the Intergovernmental Panel on Climate Change (IPCC, 2007) that global climate has warmed and that human activities (mainly greenhouse‐gas emissions) account for most of the warming since the middle 1900s.

Second opinion from an LLM

The model reads this claim and the evidence passages shown on this page, picks one of the four verdicts and cites the passages it used. It is told to judge from the passages only. You review the answer; the call and your decision go to the AI audit log in this browser.
