Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

The claim that the Younger Dryas cold event was triggered by meltwater pulses disrupting ocean circulation is well-supported by paleoclimate modeling and ocean circulation proxies.

The analysis

Papers [1] and [4] provide direct support for the widely accepted hypothesis that North Atlantic meltwater input disrupted ocean circulation (specifically weakening the AMOC) and caused the Younger Dryas cold event. Papers [0], [2], and [3] discuss meltwater pulse 1A/1B or sea-level records but do not refute the overarching consensus on the Younger Dryas trigger mechanism.

Paper [1] supports the premise by showing that ocean circulation (Atlantic meridional overturning circulation) was abruptly reduced during the Younger Dryas.
