According to research published on Monday, the world’s strongest ocean stream slowed it as a flood with fresh water, which warns “severe” climate results according to the research published on Monday.
Scientists used one of the most powerful super computers in Australia to replace the Antarctic Circampolar present by melting ice sheets, which plays a major role in the global climate pattern.
If fossil fuel emissions increased in the next 25 years-one so-called high emission landscape-present may decline by 20 percent, then the colleague reviewed research found.
“The ocean is extremely complex and fine balanced,” said Bishkhadatta Gain, scientist at the University of Melbourne.
“If this current ‘engine” breaks down, there can be serious consequences, including greater climate change – with more extremes in some areas, and accelerated global warming due to a decrease in ocean’s ability to act as a carbon sink. ”
The Antarctic Circampolar Current worked as the “Ocean Conveyor Belt” that moved the vast pillars of water through Indian, Atlantic and Pacific Oceans, Gain said.
Melting ice sheets currently dump “huge amounts of fresh water”, found in modeling.
This will change the ocean salt content, making it difficult for cold water to broadcast between the surface and depth.
Ocean plays an important role in climate regulators and carbon sinks.
The cooler water can absorb higher amounts of heat from the atmosphere.
The strength of the current – which flows clockwise around the Antarctica – also acts as an obstacle that wash the aggressive species on the banks of the continent.
Researchers have written that algae and mollusk can collect Antarctica more easily, if the current slowed down, the researchers wrote.
Even if global warming was limited to a threshold of 1.5 ° C, the Antarctic current could still be slow.
Climate scientist and co-writer Taimur Sohail said, “The 2015 Paris Agreement aims to limit global warming to pre-industrial levels to 1.5 ° C.”
“Many scientists agree that we have already reached a target of this 1.5 degree, and with the flow on the Antarctic snow, it is likely to be hot.”
The research team, which included scientists from Australia, India and Norway, stated that their findings were contrary to previous studies that currently observed the boom.
He said that further observation and modeling needed to understand how the “poorly observed area” was responding to climate change.
The research environmental research letter was published in the journal.
