Antarctic meltwater could dramatically slow overturning current

[Crick]

Can you stop dissecting my posts with this multiquote shite. I forever and a day ask you guys to stop this shit on this forum. I don't entertain re-reading my post in snippet form.

I just cannot be arsed to rey to it.

I can try

Animals (including humans) effect the climate, starting from 500 million years ago. Mass extinctions means there's a lower animal population to cause any changes on the climate.

The climate is what it is, there's no law to say if it can go fast or slow, too hot or too cold etc.. the various ocean and air streams will forever and a day move about.

One thing is evident, alarmists do not and will not and don't want to practice what they preach. Even if the climate cranks think they're being heroic by installing solar panels, they've just created demand to dig up raw materials and have panels manufactured. Just simply switch off your electric, get it discounted. If the climate hypocritical idiots do that, then they'll be in a position to preach to others. Until then, they need to shove meltwater and all the climate rhetoric right up their own backsides, show us how it's done.

Mass extinctions are not ongoing, they are singular events. Are you trying to claim that the rise of CO2 is due to increased numbers of animals?

Outside of quantum uncertainty, nothing happens without a cause. The climate does not alter, the winds do not start, stop or change direction, the temperature does not rise or fall without a cause.

Your generalization about people you describe as alarmists is bullshit. Building, installing and using solar panels will reduce the amount of CO2 being added to our air.

Just as fresh melt water in the Arctic is weakening the Atlantic Meridional Overturning Current (AMOC), Antarctic meltwater threatens the Antarctic Bottom Water (AABW) current. The globes various meridional overturning currents are responsible for an enormous amount of the nutrients and oxygen in the equatorial ocean and for transfer of cold water from the poles to the tropics. Their collapse would result in heating of the tropical oceans and loss of dissolved oxygen on which all marine animal life depends. Historically, these systems are very slow to respond and recover and these effects could last for centuries.

ABSTRACT
The abyssal ocean circulation is a key component of the global meridional overturning circulation, cycling heat, carbon, oxygen and nutrients throughout the world ocean1,2. The strongest historical trend observed in the abyssal ocean is warming at high southern latitudes2–4, yet it is unclear what processes have driven this warming, and whether this warming is linked to a slowdown in the ocean’s overturning circulation. Furthermore, attributing change to specific drivers is difficult owing to limited measurements, and because coupled climate models exhibit biases in the region5–7. In addition, future change remains uncertain, with the latest coordinated climate model projections not accounting for dynamic ice-sheet melt. Here we use a transient forced high-resolution coupled ocean–sea-ice model to show that under a high-emissions scenario, abyssal warming is set to accelerate over the next 30 years. We find that meltwater input around Antarctica drives a contraction of Antarctic Bottom Water (AABW), opening a pathway that allows warm Circumpolar Deep Water greater access to the continental shelf. The reduction in AABW formation results in warming and ageing of the abyssal ocean, consistent with recent measurements. In contrast, projected wind and thermal forcing has little impact on the properties, age and volume of AABW. These results highlight the critical importance of Antarctic meltwater in setting the abyssal ocean overturning, with implications for global ocean biogeochemistry and climate that could last for centuries.

Stopping the overturning current would lead to a massive die-off of marine species that large portions of the planet depend on for food.

Dangerous slowing of Antarctic ocean circulation sooner than expected

Climate change-driven shifts in the circulation of waters to the deepest reaches of the ocean around Antarctica, which could reverberate across the planet and intensify global warming, are happening decades "ahead of schedule", according to new research.

Climate change-driven shifts in the circulation of waters to the deepest reaches of the ocean around Antarctica, which could reverberate across the planet and intensify global warming, are happening decades "ahead of schedule", according to new research.​

...​

An earlier study using computer models suggested "overturning circulation" of waters in the deepest reaches of the oceans would slow by 40 percent by 2050 if emissions remain high.​

​

But new research released on Thursday—based on observational data—found that this process had already slowed 30 percent between the 1990s and 2010s.​

​

The cessation of the AMOC will be catastrophic in several ways.

Do you understand what a calamity the slowing or cessation of the overturning currents would be? I didn't expect you to given your general ignorance, but I did expect you to pretend some knowledge of the situation.

Changing currents won't change jack for the 40+ million year old ice age on Antarctica.

Wind and currents are weather. Climate is about how much ice Earth has.

Ocean currents are weather? Well, you never disappoint.

They are temporary and independent of climate. What controls the climate is the amount of ice on Earth - ocean level, temperature, atmospheric thickness, humidity.

Which way the winds blow and the currents flow is weather, not climate.

Cape Cod's ocean water temperature fluctuates significantly depending on current. That is not climate change.

We can only tell you to read up on the thermohaline circulation. Afer that, it's up to you. We can't force you to learn the basics. If you want to stay stupid, you will.

Problem - your fudged fraud side never proved increasing atmospheric Co2 warms the atmosphere...

Rather, the actual data proved it doesn't...

There is a consensus of those bilking the taxpayer via fudge and fraud to continue to fund themselves.

The EVIDENCE demonstrates that the as far as the Co2 fraud goes...

Data doesn't prove. It's evidence. And mainstream science has many thousands of times more data than do you and have clearly demonstrated what is wrong with your data while you have yet to show ANYTHING wrong with THEIR data save that it disagrees with the small set you favor. Does any of that mean anything to you?

God are you stupid. How many times have you been told that the IPCC conducts NO RESEARCH? None of this was produced by the IPCC.

Earth's surface temperature has risen about 2 degrees Fahrenheit since the start of the NOAA record in 1850. It may seem like a small change, but it's a tremendous increase in stored heat.

Who has the data? That’s all Michael Mann shit and Nobel prize right? Yet, data he couldn’t provide in a legal fight! Still waiting for different data then IPCC. You failed
