The current crucial system of the oceans is climate collapse and Horbarren; For now
The Atlantic Meridional Traffic is likely to collapse with global warming, but any weaken can have serious consequences worldwide
It has long been concerned that the critical network of the Atlantic Ocean currents is stalled in catastrophically changes as climate changes.
The current crucial system of oceans It is very difficult to collapse in front of Hard climate change & Horbar; If the land continues to warm up despite the predictions that would be dissolved. This is a study that proposes a study that will last until the end of the Atlantic Meridial (AMOC) Century.
The study found that the combined force of the ocean streams and winds would maintain a stable system under the most populous climate scenarios.
The authors are sure that there are sufficient evidence to protect this discovery, although the climate models studied do not reflect reality well. “It is impossible,” says Jonathan Baker, a climate author and scientist of research, Exeter, the UK Met office. “But we trust our results.” The work is posted today Nature.

Water Move Machine
Amoc is like a Giant carrier tape in the Atlantic Ocean: Warm water travels from south side to the upper layers. When the water reaches its northern point, it sinks south and travels in a cold and deep layer until it reaches the southern ocean, and it rises to the surface. Therefore, Amoce has a key role in the global distribution of hot, salt and sea water components.
Amoc’s intensity has declined over time, a trend melted polar iceChanges in wind patterns and Precipitation changes linked to climate change. Although scientists agree that the collapse of Amoc’s collapse would have devastating consequences for local and regional climates, whether such an event would happen.
The research of the future of Amoc is generally based on the analyzes of its past behavior and future scenarios simulating in different climate conditions. Some have concluded that Amoc 2025 and 2095 would soon reach the point of the point, and then shut down violently. Other research indicates that a collapse is unlikely before the end of the century, but scientists did not identify previously factors.
Model passage
Oind and his team used 34 climate models to study how I amoc to the two extreme scenarios: carbon dioxide has risen four times from the previous levels of industry; and adding massive amounts of fresh water, consistent Greenland ice sheet melting. The team found that Amoc would weaken in both stages, but it does not collapse.
The key to stability, bakery and his team, are strong winds in the southern ocean that helps to carry deep water in the region to the surface. This “highlights” has a key role to maintain amoc, because it balances the “downward” in the North Atlantic.
Bakind and his team also found that Amoc will collapse if the Pacific Meridio circulation has developed and increased the number of down. Although this traffic model is developed in all models, it is too weak to oppose the water of the highest water, as Baker says.
“It’s a very impressive and fascinating study,” says René van Westen, a climate scientist at the Meteorology Institute of Royal Netherlands. But, he added that the results of the bakers have not confirmed that collapse, as a weakening can be harmful effects. “It doesn’t mean that we can sit back and relax, it’s still a disturbing concern,” says Van Westen.
Peter Ditlevsen, a climate physicist at the University of Copenhagen and AMOC suggests that he would fall before the end of the century. Like a Baker, it has emphasized that reducing greenhouse emissions is essential to prevent corruption. “Time issues,” he says. “We don’t want to hit a good point. And it’s one of the most dangerous.”
