Not a question, When the AMOC lows down, the water piles up like sort of a trafic jam along the East coast, adding to sea level rise, even up in Nova Scotia by a few centimeters. Double check as always. And thanks for your videos.
@@a.randomjack6661 Yes, geostrophic flow causes some parts of the ocean near these Western boundary currents to have higher sea levels. I didn’t have time to go into sea level changes in this video, but a weaker AMOC will definitely have a big impact on North American shorelines.
I remember years ago reading that a slowing AMOC would lead to weakened polar jet streams, which would lead to the stalling weather patterns we're now seeing at the mid-latitudes (heat domes, extreme rains, polar vortices).
Yes, polar jet streams are very finicky and can be easily disturbed by unusual heating/cooling patterns. It's another example of how global warming can cause regional cooling, which is ironically used as a counterargument to the existence of climate change in the first place.
@@PlanetZeroVideos states like NJ, CT, RI, PA, MA etc already are partially in the colder climate zone, but the areas near the coasts and lower elevations are more temperate similar to what southwestern coastline of Norway, and Southern coast Sweden are, differences is that summers in NJ CT on coasts etc are hotter in the summer and southern Sweden etc are cooler during the summers. Gulf stream slowing means areas in the Northeast U.S like Cape May NJ, Long Island NY, Cape Cod MA etc become colder like the current climate of what southern ME aka Portland ME has currently. It would mean that states like VT, NH, and ME become subarctic and alpine in the higher elevations. Upstate NY, western MA, northwest NJ, northern PA, northern CT, northwest RI, would be subarctic and some areas in those regions could also be alpine. Southeast U.S, and Midwest U.S states would also be affected by the gulf stream current slowdown too.
Northeast passage is still frozen. The seawater by the most of the east coast of Greenland seems to be frozen, too. Near the west coast of Greenland I see open water. Gulf stream does not care for your models.
Well... Things they won't mention... Historical news articles from the 30s showed similar melt activity, but CO2 levels were lower. Then the weather turned cold through the 40s untill the lows of the 70s. Around that time, there was fear of a new ice age. Also, satellite data shows no net warming over the last few years.
If the AMOC does shut down, it gets colder in Northern waters which decreases the melt of Greenland, increases the cooling of surface water and increases the production of brine from freezing sea water. All of these factors will tend to restart the AMOC. Then the whole process starts again. We could well see a flick flacking between the two different climate phases. This would be even more harmful than a switch to a new climate regime. You would never know from year to year what to plant and would be likely to always be out of phase. Big starvation.
Interesting point... this assumes that the rate of heating from global warming does not completely overwhelm the cooling effect from the meltwater. But agreed, flipping back and forth across a bifurcation point is not good for long-term ecological stability.
It definitely plays a factor since heat transport from the equator northward has been decreasing slowly. This is a prime example of when global warming causes regional cooling, something climate change skeptics love to point out without understanding why it's happening.
However, the Agulhas leakage would intensify the AMOC in Southern Hemisphere by the warming climate and poleward shifting of southern westerlies, so the melting Greenland ice sheet might not be a single effect on AMOC
Save the planet , ride a bicycle or ebike , use a solar cooker and a clothes line , tankless water heater or solar , insulated windows ,ect and we shuld use stainless or maybe wood boxes for food , so we dont need to use plastic bags for food at the store . stop having so many kids .The longest journey starts with the first step !

Nice video. However it is not true that the foreseeable meltwater release is gradual. The risk of a shutdown of the current is much higher than they make it to be.
The Gulf stream is going through the normal cycle that it has followed for millions of years! The warm Gulf of Mexico is what drives the Gulf Stream and over the last 10 years the Gulf of Mexico has cooled 5 degrees at 60 feet so the Gulf Stream is slowing and will stop once again.
While I agree the main point we are facing is that it's happening extremely fast, this means that life, including humans, does not have time to react and adapt to the changing weather which could bring about apocalyptic scenarios. I don't think anyone can disagree that human presence on the planet has a significant impact on the climate which in turn is going to bring about this shift quicker and more ferocious than before. A good example would be a car, your argument is a car going from 60 mph to 0 mph is extremely common and happens. The point scientists and anyone with a brain are trying to make is that the speed at which you go from 60 mph to 0 is the difference between living and dying. I'd prefer to go at a slower rate compared to a dead stop like hitting a tree.
I agree, however the point I’m trying to make is that there is a difference between the previous times the AMOC has slowed versus this time, that being the anthropogenic carbon dioxide emissions warming the system. Will life find a way to survive if the AMOC shuts down? Of course. Will humanity be able to survive with the AMOC? Of course. However, entire ecosystems, industries, and hundreds of millions of people will be negatively impacted directly from this system changing. Humanity is not above geologic systems; we wholly depend on the Earth and it’s biodiversity to survive. We should not write off this AMOC weakening as unimportant because it’s happened before.
This is the exact train of thought ExxonMobil, Chevron, and BP want you to be on. Thinking pessimistically about climate change will only leave our planet in its worst case scenario for the next generation when we inevitably leave.
Nearly all the oxygen in the ocean comes from the sea-air interface at the surface. More mixing of the ocean due to currents will for sure mean more movement of that surface oxygen across deeper waters. They're also really good at shuttling nutrients around that are dissolved in the water
@@PlanetZeroVideosAlso the colder the water the more o2 it grabs . And if we dont replant the trees we cut down , I guess we wont have the o2 to begin with , ecept for other plants and ocean plants . and when the ocean o2 gets low enough I think the alge grows and can cover ocean plants and grasses blocking photosithisis causing it to die .🤔 I think like 70% of the oxygen comes from the ocean . I wonder how much o2 gets used up in cars alone ? The domino efect of nature is so vast . too bad more people dont ride bicycles ! I cant imagine the thousands of gallons of gasaoline I did not burn in the last six years by simply riding my bike instead of my truck ! But I can do better , with a solar cooker and a cloths line . and to keep reducing plastic useage , I saw a great movie called trashed , it does no good to recycle plastic if the toxic fumes from the proscess poison us . I think people should be urged to have less baby's !
@@jacobclark89 This is true, colder waters dissolve more gases, which is why oxygen minimum zones (OMZs) are expected to grow as the planet gets warmer and the ocean can hold less O2. Fortunately, trees aren't the only source of O2 on our planet.
Me too, I first read about it around 1997, the slowing if even not hitting tipping point still plays a role in further destabilizing weather patterns, ua-cam.com/video/GPhzI6OIj1o/v-deo.html
this documentary shows we can minimise the effect of a dying Gulf Stream at least by transitioning from fossil fuels to renewable energy,solar power, electric powered nuclear power plants and Hydrogen Energy.
terrific, there have been numerous studies by done on how to get to a 100 % renewable, energy grid, wind, solar, geo, hydro, grid connectivity and energy storage, this show is before my editing improved but u may find it very helpful ua-cam.com/video/a7iVwCPkPqU/v-deo.html
The crucial question is. Can all of America and for that matter,the rest of the world. Transition fast enough to bring fossil fuels usage and co2 to carbon neutral. Add to that equation, the suppression from the F.F industries has to be eliminated first. As we know there are more than a fair Share of politicians who have sold out to these corporations and will defend that cash stream to the end.
Haha, what's surprising to me is that the volume of freshwater input is less important than the rate of freshwater input. The same amount of meltwater over the course of 10 years would have much less of an impact on the AMOC than the same amount in one year.
@Mr. M.O.G.O.M. Not quite. Water has an incredibly high heat capacity so even if every last block of ice at both poles melted, it would not significantly lower ocean temperatures globally. Even if it did, the heat required to melt such a volume of ice would quickly rewarm the meltwater in a matter of months/years.
What other questions do you have about the AMOC tipping point? Let us know! 🌍

Is this why we’re seeing unusually cold springtime’s in the Uk recently?
It definitely plays a factor since heat transport from the equator northward has been decreasing slowly. This is a prime example of when global warming causes regional cooling, something climate change skeptics love to point out without understanding why it's happening.
The colder springtime is getting more and more apperant in Norway as well
