This is big, folks.

Last year, a bombshell scientific study suggested a scenario that has long worried scientists was coming to pass: a slowdown in the North Atlantic ocean currents that usually redistribute warm and cold waters, thanks to massive ice melts in Greenland and other Arctic changes.
If this is really happening, it’s a big deal.
The circulation, sometimes called the Atlantic meridional overturning circulation or AMOC, transports enormous amounts of warmth northward from lower latitudes. If it slows down, there will be less heat transport to Europe and higher latitudes, as well as key consequences for warming and sea level rise along the U.S. east coast.
However, this is a vast, enormously complicated and inadequately studied ocean system, and there are well-known patterns of natural variability in the Atlantic that could also drive things.
Indeed, the circulation had already been observed to be slowing over the past decade, but it is less clear whether this slowdown is the result of climate change or, simply, part of that variability (or both).

As the years progress, VT has been kind of dragged from his initial denialist position (where he came across as denialist but wanting to shy away from self-describing as a denialist) over to what sounds like a downplaying position. That's the way he's gonna be, always trialing behind the current party-line on where we're headed.
Just pointing out the contradiction between record rates of arctic sea ice melt and having the gulf stream slow down and or having a cold area in the North Atlantic. If both are true simultaneously there has to be some rather complicated explanation for it.

???
The explanation is rather straightforward, actually.
Perhaps you could be clearer about what you find 'contradictory'?
dohboi wrote:Your question is incoherent. Melt of ice IS going to be the major cause of any AMOC slowdown that happens, mostly because it will freshen the surface water, but also cool it.
Yet for some reason you seem to think that melting ice is some kind of proof that the AMOC can't slow.
But if you don't want to talk about it, that's fine.
