Global warming is causing & # 39; a really huge increase & # 39; in the energy of ocean currents

A study has found that Earth's oceans are accelerating as global warming has caused strong winds and a "really huge increase" in the energy of currents.

An international research team found that wind speeds have increased 4% over the past two decades, agitating the ocean faster at depths of up to 1.86 miles.

Current speeds increased on average after the 1990s, they report, with 76 percent of the top 1.86 miles now moving faster than they were before this threshold.

The team said there has been a 15% increase per decade in current energies in the period 1990-2013, more than can be explained naturally.

The findings contradict previous studies that suggest that climate change would weaken ocean circulation and, in particular, in the tropics.

"The Earth is our patient, and one looks for symptoms of how he is reacting to the anthropogenic forcing of greenhouse gases," said article author and physical oceanographer Michael McPhaden the Washington Post.

"This is another symptom," added the researcher at the US National Oceanic and Atmospheric Administration. UU.

In their study, Dr. McPhaden and his colleagues used five so-called & # 39; reanalysis & # 39 ;, a process in which real-world observations are combined with models to help complete missing data points, to calculate the Total kinetic energy of the oceans.

The researchers found that, while there were small variations before, the total kinetic energy of the oceans increased dramatically in the early 1990s.

To verify these findings, the team then resorted to measurements of ocean currents made by the Global Marine Argo Atlas between 2005 and 2010.

This is an international project that uses thousands of so-called floats, scientific platforms loaded with sensors, which are adrift to gather the date on the ocean.

While floats do not measure water velocity directly, they can indicate where winds have accumulated water, creating pressure differences that drive larger flows.

The team found that data from ocean floats pointed to an even clearer acceleration of global currents than initial reanalysis models.

"The evidence in the Argo data is absolutely staggering," said researcher at the National Oceanography Center in the United Kingdom, Eleanor Frajka-Williams, who was not involved in the study. Sciences magazine.

According to the researchers, it is possible that a more turbulent ocean can absorb more heat from the atmosphere, or change how and where heat circulates.

This could have diverse and unpredictable side effects on ocean life.

"Perhaps the most important consequence is the increase in heat redistribution around the planet that stronger circulation would bring," the ocean expert at the University of New South Wales Alex Sen Gupta told the Washington Post.

"This would affect temperature distributions and could affect weather patterns, but more work would be needed to make these links."

The researchers noted, however, that the observations in their study were limited mainly to the upper 1.24 miles (2,000 meters) of the oceans.

Given this, they added, comprehensive studies of global circulation patterns and rates in the deepest ocean are urgently needed to improve predictions of how the seas will continue to change in response to future warming.

The full findings of the study were published in the journal. Scientific advances.

WHAT IS THE GLOBAL OCEAN CONVEYOR BELT?

When it comes to regulating the global climate, the circulation of the Atlantic Ocean plays a key role.

This is due to a system of deep-sea movement in constant motion, often referred to as the Global Ocean Conveyor Belt, which sends warm and salt water from the Gulf Stream to the North Atlantic, where it releases heat to the atmosphere and heats Western Europe.

The coldest water then sinks to great depths and travels to Antarctica and finally circulates back to the Gulf Stream.

This movement is fed by thermohaline currents, a combination of temperature and salt.

It takes 1,000 years for water to complete a continuous journey around the world.

The researchers believe that when the North Atlantic began to warm up near the end of the Little Ice Age, fresh water disrupted the system, called the South Atlantic Dump Circulation (AMOC).

The Arctic sea ice, and the ice sheets and glaciers that surround the Arctic began to melt, forming a huge natural freshwater tap that sprouted in the North Atlantic.

This large influx of freshwater diluted the surface seawater, making it lighter and less capable of sinking deeply, slowing the AMOC system.

The researchers found that AMOC has weakened more rapidly since 1950 in response to recent global warming.
