Atlantic gulf stream is vanishing...very bad news for all of us

Times up on the climate change and global warming stuff. Once the oceanic regulators of temperature stop functioning...well, it's likely to be a significant game changer for weather patterns. Exactly how this will play out isn't clearly understood...but we are going to find out first hand.

Sucks!

And we'll roll with it, always have always will...until we can't.

From what I understand winters in the UK/NW. European nations? Will get much colder without the gulf stream pumping relatively "warm" water up there.

Like London will be getting Canada/Russia cold...regularly.

Doubtful. Most likely this is just natural ebb and flow dynamics

Which can be a real Bitch! for a long time!

Yeah, what is worth watching is the slow down of massive storms like Hurricanes and nor Nor'easters. This is a recent phenomenon. If the don't move or stall that has been devastating...already seen in Texas bad North Carolina.

Last sequence of ice ages were natural.
Interesting read
Change is happening for whatever reasons and we need to adapt... like, I dunno throwing a ball in the air, winterising power networks?

Place an ice cube in a pool. Monitor the temperature. Does it change? No. Why? The volume of the pool and the surface in contact with air negates the cooling that happened. Even though Greenland is melting...the likelihood it is changing the temperature profile of the Gulf Stream is unlikely (at this time). It is a matter of physics.

So what is happening? Best guess without analyzing the data...freshwater is lighter than saltwater. A lens is created. The depth of this lens is small...10...maybe 20 ft. Guess what? Our monitoring devices are in that depth. Go down 50 ft. Is the Gulf Stream still chugging along?

From the article
"To learn more, researchers have slung necklace-like sensor arrays across the ocean, not only on the surface, but hundreds of feet deep."

But also
"A 2019 report by the United Nations’ Intergovernmental Panel on Climate Change, a synthesis of the most significant climate research worldwide, says that while the AMOC will “very likely” weaken later this century, collapse is “very unlikely.” Yet Dr. Rahmstorf worries about the unknowns in a system that scientists understand can rapidly shift between different states."

And in summary
"This is the place scientists currently find themselves in. They suspect the AMOC can work like a climate switch. They’re watching it closely. Some argue that it’s already changing, others that it’s too soon to tell.

“There’s no consensus on whether it has slowed to date, or if it’s currently slowing,” said Dr. Lozier. “But there is a consensus that if we continue to warm the atmosphere, it will slow.”

I don't want to get into another one with you so I'll leave it there.

Oddly enough I did quite bit of reading into Greenland and you can read all about it in a very hot story
