The scientists conclude:
‘It is therefore essential that we continue to improve our understanding of the LSW/subpolar gyre dynamics at a range of time scales to reduce uncertainty in future climate predictions.’
[LSW = Labrador Sea Water]
By Paul Homewood
A newly published paper has linked changes in European climate to North Atlantic variability over the last 3000 years:
ABSTRACT
The subpolar North Atlantic is a key location for the Earth’s climate system. In the Labrador Sea, intense winter air–sea heat exchange drives the formation of deep waters and the surface circulation of warm waters around the subpolar gyre. This process therefore has the ability to modulate the oceanic northward heat transport. Recent studies reveal decadal variability in the formation of Labrador Sea Water. Yet, crucially, its longer-term history and links with European climate remain limited. Here we present new decadally resolved marine proxy reconstructions, which suggest weakened Labrador Sea Water formation and gyre strength with similar timing to the centennial cold periods recorded in terrestrial climate archives and historical records over the last 3000 years. These new data support that subpolar North Atlantic circulation changes, likely…

Roger, all,
Most everyone understands this backwards. You turn water into ice by removing energy. You are building the most ice during warm times, that is why IR out is high in warm times. The energy is coming from turning water into ice. Cold times are when there is not much IR out, cooling cannot come from that. The cooling is coming from turning ice back into water. Ice Rafted Debris is part of this ice floating into warmer water where it is more effective in promoting cooling from thawing.
IR out during warm times stores enough ice to cause earth to cool later. There are cycles. Other theories have no logic to explain cycles.
Ice extent is in phase with temperature. Other factors only correlate sometimes.

Still in November…so much for children won’t know what snow is 🤣
The Ice Man Cometh

The activity of the Gulf Stream is particularly important and Bond et al suggest that it is periodically cut off by the cold Labrador current allowing drift ice, blown by northerly winds, to advance much further south into the N Atlantic than occurs at the present time. [bold added]

Paper (see post): The subpolar North Atlantic, specifically, is a key region for understanding climate variability, as it is one of the world’s main areas of deep water formation.
. . .
Our new findings suggest centennial changes in the circulation of the subpolar North Atlantic, likely modulated by the input of Arctic Ocean waters to the Labrador Sea, with similar timing to climate variability recorded on land in historical and terrestrial proxy data in Europe for the last 3000 years.
