The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Happened as dated, per the source: the findings "were published in the Earth and Space Science journal at the end of 2024."
Wikipedia's general Subsidence article, fetched directly, does not mention the University of Miami study or Miami skyscrapers at all - a tangential, general-background reference only, consistent with its comparatively low 60 confidence score.
GFZ could not be fetched due to a network restriction, but its headline, "Miami's rapid growth comes at a price: new study reveals sinking buildings", and 8 January 2025 publish date - shortly after the pin's stored 15 December 2024 date - corroborate the study the pin describes.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
