Abyssal ocean overturning slowdown and warming driven by Antarctic meltwater

evidence

Antarctic meltwater freshening shelf waters is projected to drive a substantial slowdown and warming of the abyssal overturning cell fed by Antarctic Bottom Water. Associated observational figures quoted here — an approximately 30 per cent decline in Weddell Sea Bottom Water volume since 1992 and a greater than 40 per cent decline in shelf sea-ice formation rate — come from adjacent studies summarised alongside it, not from this paper.

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