The most effective mechanism for stabilizing low atmospheric O2 is reducing global rates of biospheric productivity.
“As a result, there is widespread agreement that the most effective mechanism for stabilizing low atmospheric O2 is reducing global rates of biospheric productivity (Laakso and Schrag, 2014; Derry, 2015; Reinhard et al., 2017a).”

A decrease in atmospheric O2 levels should, in general, lead to an increase in organic matter burial (and thus O2 release), while also leading to a decrease in organic matter weathering and thus reduced O2 consumption.
“For example, it is widely accepted that a decrease in atmospheric O2 levels should, in general, lead to an increase in organic matter burial (and thus O2 release), while also leading to a decrease in organic matter weathering and thus reduced O2 consumption (Laakso and Schrag, 2014).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
