New Alarmist Claim: Global Warming Could Shut Down Ocean Currents

Using computer models that project hundreds of years into the future are n0w telling scientists that global warming could completely shut down earth’s ecosystem, namely, ocean currents. This is the most absurd speculation in years from the scientific community.  TN Editor

Intense future climate change could have a far different impact on the world than current models predict, suggests a thought-provoking new study just out in the journal Science Advances. If atmospheric carbon dioxide concentrations were to double in the future, it finds, a major ocean current — one that helps regulate climate and weather patterns all over the world — could collapse. And that could paint a very different picture of the future than what we’ve assumed so far.

The Atlantic meridional overturning circulation, or AMOC, is often described as a large oceanic conveyor belt. It’s a system of water currents that transports warm water northward from the Atlantic toward the Arctic, contributing to the mild climate conditions found in places like Western Europe. In the Northern Atlantic, the northward flowing surface water eventually cools and sinks down toward the bottom of the ocean, and another current brings that cooler water back down south again. The whole process is part of a much larger system of overturning currents that circulates all over the world, from pole to pole.

But some scientists have begun to worry that the AMOC isn’t accurately represented in current climate models. They say that many models portray the current as being more stable than real-life observations suggest it actually is. Recent studies have suggested that the AMOC is weakening, although there’s some scientific debate about how much of this has been caused by human activities and how much by natural variations.

Nevertheless, the authors of the new study point out, many climate models assume a fairly stable AMOC — and that could be affecting the predictions they make for how the ocean will change under future climate change. And because overturning circulation patterns have such a significant effect on climate and weather all over the world, this could have big implications for all kinds of other climate-related projections as well.

“This is a very common and well-known issue in climate models,” said the new study’s lead author, Wei Liu, a postdoctoral associate at Yale University, who conducted the work while at the University of California at San Diego. “I wanted to see, if I use a corrected model, how this will affect the future climate change.”

Liu and colleagues from the UC-San Diego and the University of Wisconsin at Madison took a commonly used climate model and corrected for what they considered to be the AMOC stability bias. Then they ran an experiment to see how the correction would affect the model’s projections under future climate change. They instantaneously doubled the atmospheric carbon dioxide concentration from present-day levels in both the corrected and uncorrected models, and then they let both models run for hundreds of simulated years.

It’s more likely that supported by their rotten polit and MSM whores these currents will be shut down with some kind of climate/geo engineering technology to have a reason to grab more money from their western slaves.
Could also be the sun itself – the new ace age is coming BIG TIME. Nearly half of the starting phase is over.

What makes up the waves, the wind? Friction, rotation, gravity (moon), temperature the speed of which, on the surfaces of the waters depends. To what extent does temperature have an effect on water density and motion on the continuous of the water’s depth? Water density is affected but the temperature but by how much is the conveyor belt of water currents, regardless of size, by each degree, as little as it is, compared to other factors?

Wouldn’t global cooling also change the ocean currents? With the sun’s output dropping we’re in for a tough time.
