Ah that makes sense.
So in contrast to what the #NOS quote suggests, it's not so much that the #AMOC causes the climate in #Europe to be warmer than that of (the comparable part of) #Canada. It actually prevents it from being much colder.
(Where "comparable" should then not only be understood in terms of latitude, but also in terms of the east-west exposure to the ocean.)
Good luck science-communicating that ...
Vancouver is located at a similar latitude as Lourdes-de-Blanc-Sablon, but at the west coast of #Canada.
Therefore it receives relatively warm air from the ocean in the winter, which means its winter temperatures are similar to those of Amsterdam.
In fact, despite the absence of an #AMOC equivalent, #Vancouver 's average winter temperature appears to be slightly higher than that of #Amsterdam?
@BartVerheggen Any thoughts?
"Met de kennis van nu is het meest waarschijnlijke scenario nog steeds dat het warmer gaat worden. Alleen is dit een nieuw inzicht dat we niet kunnen negeren", zegt Deltacommissaris Co Verdaas die de werkgroep leidt. Een inzicht met verstrekkende gevolgen. Omdat de veiligheid van waterland Nederland mogelijk in het geding is, leidt de Deltacommissaris de werkgroep.

@Sustainable2050 Any idea how long developments around the #AMOC area already seriously looked at in research? 10-15 years at least?
Finally, the Netherlands is seriously looking into the effects of a possible weakening/collapse of the Atlantic Ocean heat circulation. This could mean significantly colder winters for the Netherlands.

The @NOS is picking up on the news about a potential breakdown of the Nort Atlantic Ocean Circulation #AMOC
But just to be clear (as it is not specifically mentioned in the article): such a cooling over Northwestern Europe would be *caused* by global warming, leading to excessive melting of the Greenland ice cap, thawing of permafrost and a large influx of freshwater into the Atlantic Ocean.
Nor is this scenario entirely new: already in 2004 there was a major Hollywood movie around this idea ( The Day after Tomorrow).

The #Forest After Tomorrow:
Projecting the Impact of a Collapsing Atlantic Meridional Overturning Circulation on European #Tree-Species Distributions
...As opposed to the classic climate-change scenario supporting Mediterranean species in Central Europe, projected European tree-species portfolios consisted of a higher share of boreal, cold-tolerant species in the inactive AMOC scenario.....while others such as the spruce almost went extinct.

In 1989 James Burke produced a documentary named "After the Warming" which highlighted the effect of slowing the global thermohaline circulation current.
"That was the key to everything. Change the saltiness of the Atlantic and you change the world's weather."

#AMOC: The Atlantic’s Hidden Tipping Point - that is the topic of a short explainer video which I did for the Climate Crisis Advisory Group, with Tori Tsui.

(My two cents: As long as we keep igniting carbon bombs in exponential manner, no amount of geoengineering will be able to mitigate the effects.)
New summary by @rahmstorf
Is the Atlantic Overturning Circulation Approaching a #TippingPoint?
"But the fact that all these studies, using different methods, point in the same direction, toward a risk that is much larger and earlier than we had thought until a few years ago, is a major concern. My assessment of these ... studies is that by the time they can provide a reasonably reliable warning of an impending #AMOC tipping, it will be too late to prevent it."

#MPIM researchers have uncovered the origin of these strong temperature fluctuations over the past 20,000 years using a novel coupled climate-ice sheet model. They found that #iceberg armadas
