Ocean Current That Keeps Europe Warm Is Weakening Because of Climate Change (washingtonpost.com)
The Washington Post: The Atlantic Ocean circulation that carries warmth into the Northern Hemisphere's high latitudes is slowing down because of climate change, a team of scientists asserted Wednesday, suggesting one of the most feared consequences is already coming to pass (Editor's note: the link may be paywalled; alternative source). The Atlantic meridional overturning circulation has declined in strength by 15 percent since the mid-20th century to a "new record low," the scientists conclude in a peer-reviewed study published in the journal Nature. That's a decrease of 3 million cubic meters of water per second, the equivalent of nearly 15 Amazon rivers.
The AMOC brings warm water from the equator up toward the Atlantic's northern reaches and cold water back down through the deep ocean. The current is partly why Western Europe enjoys temperate weather, and meteorologists are linking changes in North Atlantic Ocean temperatures to recent summer heat waves. The circulation is also critical for fisheries off the U.S. Atlantic coast, a key part of New England's economy that have seen changes in recent years, with the cod fishery collapsing as lobster populations have boomed off the Maine coast.

That's one of them-there feedback mechanisms that cools the poles in the event they get too hot. I recall hearing about it twenty years ago, in the context of "No, the world won't end because of global warming, the planet has feedback mechanisms to dump excess heat. That's how it's still nice and comfy here after billions of years."
and I'm getting about a foot of global warming deposited onto my driveway. Yup, this science is definitely settled.
Please measure in libraries of congress. Tx

Don't get me wrong, I personally think that ACC is real, and a problem. But––
The story I heard on NPR [1] today said:
...scientists disagree about what's behind the sluggish ocean current...
but did go on to say:
The only thing we really can do is obviously try and prevent global warming because that's the root cause of why we think it's weakening now...

Republicans lie like people who enjoy lying.
/. already solved this in February.
Humans deserve Global warming, and every consequence of it. I say "Bring it on!"
I was just a little ahead of my time. But the business plan was sound.
SJW: Someone who has run out of real oppression, and has to fake it.
Then I guess it's a lie for a lie since Democrats also lie like people who enjoy lying.
Versus who's paying you to be a troll here. Should I call you Ivan? Or Sasha? Or Dmitri?
There's not going to be global cooling. In 6 years, Galactic Overlord Zenu is going to come back and rapture up all the level 7 or higher Scientologists and then blow up the planet.
Your ad here. Ask me how!
There is still some good conversation here on technical subjects, but on climage change it's a bunch of people who know very little about the subject being jerks.
There is no "cooling trend". The current as it is today provides anomalously warm temperatures to northwestern Europe. If this current is fully disrupted, the UK and friends will end up having the same general climate as northern Canada. Along with northen Canada, it then will slowly warm in accordance with the generally accepted global rates.
You are in a twisty maze of processor lines, all alike.
There is a lot of hype here.
I know you are making that up, the correct spelling is Xenu, or you haven't reached level OT III yet.
Xenu information if you want to be better informed. If you have NO IDEA who Xenu is, please read it. I was on the floor crying because I was laughing so hard the first time I saw it.
This is Slashdot!
Here, global warming is a conspiracy thought up by an alliance of greedy scientists and secret globalists in their war against the honest, hard-working executives of the petrochemical and other carbon industries.
Ocean Warming & Acidification - Dr. Alex Cannara
Gradually rising temperatures and seas are but a mere inconvenience next to the impending mass extinctions in the oceans and disruption of ocean currents. It is happening now, and there are already large dead zones that are now incapable of supporting life. To prevent global catastrophe will require enormous amounts of clean energy, not the symbolic non-solutions that are in vogue today.
You do realize that the poster you quoted there is a Global Warming denier, right?
We know Soros pays trolls and funds riots and fake voters and a bunch of other evil shit. All public fact.
Russian trolls? All 13 of them post to slashdot every day?
No. A lot of people just think you're full of shit like the rest of your dnc sheep brethren. No one has to be a Russian troll to oppose your idiocy.
No. It is a conspiracy of ultra leftist socialist scumbags who have created this as just the latest in a long line of scams to raise taxes for their pet projects, kill the West, eliminate feeedom, and reduce all the non-elite (this means YOU reading this now) to virtual slaves working until you die to keep the 1% socialist elites living in luxury.
This is how you spend the day off you got from sucking Putin's dick?
Loser
What would really suck if Euro Jetstream disappeared whole content would be under miles of ice in a few years.

Hey, some Leftists hate gays or blacks or women too you know. We just understand that cutting our own nose (rights) off to spite our face is counter productive.
Sure, if we hate gays, black AND women, or are just closet pedos we become Trumpers, but Leftists can just hate a few things, instead of ALL things.

The irony is that, not all that long ago, these idiots were soviet apologists.
Skimmed through the article. Did not find any facts but found a lot of "may" and "think(s)".
Based on this I "think" the author who set the subject "may" be an idiot.
Climate changes
I may be an idiot as well, as I left out the important part: we know it's weakening, but is it all due to human made climate change?
Paris accord will solve all the issues with Climate Change. I am sure that if we do not focus on stopping growth in emissions, and instead all focus on per capita emissions while allowing CHina, India, Brazil, South Africa, etc to grow, that it will solve all of these issues.
I mean what could possible go wrong with stopping 1 small group of ppl while allowing others to grow far bigger in their emissions.
I prefer the "u" in honour as it seems to be missing these days.
Muslims and other swarms of less desirable humans are less likely to stay or migrate to cold climates. Even now they are exiting Iceland and Finland due to the hostile environment.
Keep it up and perhaps they will all stuff off back to where they came from.
The sad truth is most folks don't realize how fragile our planet is, it's a finely balanced chaotic system where a slight change in something as small as the CO2 concentration in the air is enough to cause a massive shift in climate. Nature normally takes thousands of years but we're essentially speeding it up into centuries or even decades. It's been known for years that the ocean sea currents could change with climate change and unfortunately it looks like it's coming true. If the oceans current shutdown it won't just cause Europe to get cooler. It could disrupt the monsoon rains which allow India to farm and provides water. If you have a billion people starving to death, I wouldn't want to explain to them how this wasn't my fault and I'm not sharing.
Let's sort things out "easily" (you know in science that's an euphemism for "mostly but there are also other things you don't talk about") for many people who doesn't understand how this "Climate Change" works.
0) Our Climate lies in equilibrium of freshwater-saltwater. A difference in salt concentration is what makes the ocean water currents move; just like pressures differences make air move.
1) Higher temperatures mean ice (freshwater) reserves melt faster. This implies a "shift" in equilibrium towards less salted water, implying the current doesn't have enough "salt concentration" differences and, hence, stop moving.
2) When the currents move, the water is cold (near the poles) and warm (near ecuator) and that cold/warm is taken by the moving air to landmasses. If the current stops, it means top will always be cold and bottom always warm.
3) And the final consequence of Global Warming is an Ice Age...
On (1) you can debate "why" the temperatures rises. You must take in account that the temperatures "changes" normally (maybe a solar eruption, hotspots, forest fires, etc. or, on the other hand, a ice mases sliding, more raining, etc.)
The problem is not that "they have changed" (that's what the ignorants keep talking about). The problem is that "they have changed TOO FAST", meaning, there's "other" thing apart the "normal temperature changes ratio". Here is where humans come in. Maybe it's fossil burning, plastics on ocean that reflect light, etc. whatever meaning "contamination".
The second problem is that we have passes years ago the "No Return Point", meaning, even if we stop contaminating, the Climate Shift won't stop at all. Then, why stop contaminating?
Well, there are two reasons I think, personally, on my own, YOU SHOULD BE WORRY ABOUT TOO:
A) Your descendants need a clean environment to live or will suffer (greatly). I, personally, will fight to protect my family from your (the ignorants' and criminals') crimes against Nature.
B) The most contamination, the shift will happen sooner. What's the problem then? Well, for example, if in your region you suffer 2 tornadoes each year, you'll "enjoy" 5 next year, 8 the following one, etc.
The only "hope" is that if humankind survives the Ice Age (and stops [or at list reduces considerably] contaminating), after that Ice Age, the Earth will try to recover the previous equilibrium state.
Meanwhile, millions would have died due to the Climate Shift/Change -- Global Warming, whatever you choose to call it.

I agree, although I'm not sure he just needs an explanation about sarcasm tags, or mental health care.
America has the best excuse, ignorance !
If windtroll is any indication, they don't even realise how dirty they are.

Thanks Evgeny. Somehow Soros telling people to riot doesn't ever make the news.
But Putin's cock holster telling his thugs to "beat the crap out of 'em" made the nightly news.
We see who you are. Pretty sure you won't be able to retire on what Twitler pays you for your trolling.
These headlines is getting stupid...
Waa global cooling oppressing me in the night.
Every night, temperature drops by an average of 1 degree per hour and stays that way at least 10 degrees below day time for hours on end.
Waaaa... glow ball cooling is me oppressing me in the night.
non-deniers to blame
It's nothing new, it has happened before, it may be happening now, it will happen in the future. It is inevitable (but we should of course not stop fighting it).
We are racing against the clock, always has been and always will until we make technological advancements that allow us to either colonize other worlds, or to artificially provide the hospitable environment we need to survive even when majority of Earth becomes inhospitable.
So if uneducated morons and media could stop spreading misinformation about GMO, AI, nuclear and other taboo concepts and embrace the opportunities the technologies give us, we would be one step closer to the survival of the human race.
I once came up from my subterranean cave under my mom's house. Went into the big room with the blue ceiling and the green carpet. Experienced Warming from that Glow Ball up high first hand. Never again!
I recall reading about this topic roughly 20 years ago in an issue of National Geographic except then it was reported as a natural occurrence rather than man made climate change. They were noting temperature changes as far back as the 70's and speculated that the warm air that produced what felt like unnatural weather would shift to a different area of Europe at some point.
No, just most of it. The remainder is due to a flock of chocolate chickens holding a house party in Hawaii, and some guy in a Mickey Mouse suit in Moscow.

I heard it on Faux news.

Feel free to repost. I'm posting as AC because I don't have an account...
So global warming will lead to lower temperatures? Ironic.
A cold Europa ? OOOH the po' Froggie/Limey fucks. Freeze the Trotsky bastards I say ... and let West-marching Slavs eat them like iced sushi !
Thank you for your help in this matter. Unfortunately you'll be getting lead poisoning at some point. Not now but when your useful idioting is no longer useful, it will come when you don't expect it.
..and I'm the Pope.
You must feel good knowing how stupid your fellow Americans are, they will back your absurdity, as they are as ignorant as you are.
I no longer believe any assertion that contains the phrase "because of climate change." The planet's environment is too complex to model; any attempt to do so is doomed to failure, with one of the results being that people make all kinds of goofy predictions based on unreliable results.
Circle the wagons and fire inward. Entropy increases without bounds.
2 things immediately spring to mind.
1. They sound much more like an average Chinese person than you sound like an Average American.
2. The story of the little boy who cried wolf.
You lied about where coal comes from. here
You lied about China's coal production, consumption, and CO2 here, As well as America's emissions in the same post.
You also lied about how easy it is to mine 5km under water here.
And that's just the last page in your history...
Care to back up any of those lies with links?
