Declining Coral Calcification on the Great Barrier Reef

evidence

Calcification in massive Porites on the Great Barrier Reef declined by about fourteen per cent from 1990, a change the authors described as without precedent in the preceding four centuries of the skeletal record. V55 verification basis: not consulted; the figure is stated from the producing model's knowledge. This result has been the subject of subsequent methodological debate that could not be reviewed here.

A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
