Stratosphere targets deep sea to shape climate: North Atlantic 'Achilles heel' lets upper atmosphere affect the abyss

Stratosphere targets deep sea to shape climate: North Atlantic 'Achilles heel' lets upper atmosphere affect the abyss: A new study suggests something amazing: Periodic changes in winds high in the stratosphere influence the seas by striking a vulnerable "Achilles heel" in the North Atlantic and changing mile-deep ocean circulation patterns, which in turn affect Earth's climate.
