The ocean system that shapes Europe's climate

Phys · May 05, 2026 · 1010 words · By Audrey Morley

climate_change Regional Security Oceanography

The article explains the Atlantic Meridional Overturning Circulation (AMOC) and its role in regulating Europe's climate, specifically highlighting the Subpolar Gyre. It discusses the potential consequences of a system slowdown, including regional cooling and reduced carbon sequestration, while noting that current observation periods are too short for definitive conclusions.

“the Gulf Stream is just one part of a much more complex system called the Atlantic Meridional Overturning Circulation or AMOC”

VERIFIED BY REFERENCE

Wikipedia and multiple web search results explicitly state that the Gulf Stream is a component of the Atlantic Meridional Overturning Circulation (AMOC).

“warm waters move northward across the surface of the Atlantic from the tropics... After the waters have released their heat, they become colder and denser, which makes them sink into the deep ocean. These waters then return southward, at great depths.”

VERIFIED BY REFERENCE

Wikipedia and multiple scientific descriptions confirm the AMOC's mechanism of transporting warm surface water north, which then cools, sinks, and returns south at depth.

“This period of intense regional cooling, which lasted roughly from the early 14th century to the mid-19th century, was characterized by winters so severe that the River Thames froze over.”

“Scientific research suggests that this cold period was likely sustained and amplified by a regional change in the SPG while the AMOC remained relatively stable.”

CORROBORATED

Two separate web search results specifically discuss the role of the Subpolar Gyre (SPG) weakening as a trigger or amplifier for the Little Ice Age, distinguishing its role from the broader AMOC.

“Networks of monitoring tools like Rapid or OSNAP that measure the transport of water both at depth and at the surface have only been in place for about 20 years.”

Evidence shows RAPID began in 2004 and OSNAP in 2014. This aligns with the claim that these networks have been in place for approximately 20 years (or slightly less).
