Sources

Collection and republication

We use sources only after checking their terms, available fields and permitted storage. We do not save or republish full news text or original images.

We organize facts within the source’s stated scope, using our own structure and wording. Each report links to the information used to review it.

These are documented reference sources, not a complete list of current collectors or proof that every source has produced a published report. Sources actually used are shown in each report.

NASA EONET

Official event names, categories, periods, locations and reference links for reviewing natural-event candidates.

Wikimedia Analytics

Aggregated public page views, page, language and date as supporting observations. No personal data is collected. A change in views alone does not establish its cause.

GBIF

Species, observation dates, locations that can be generalized, recording institutions and data-quality information. An occurrence record alone does not establish a change in the species’ overall distribution.

Crossref

Public bibliographic metadata such as titles, authors, publication dates and DOIs. Metadata alone does not establish a paper’s findings or conclusions.

Government agencies

Official public announcements, statistics, observations, explanations and update dates. Claims are limited to what the source record actually states.
