The global circulation of the sea appears to slow downNASA

Scientists are very keen that global ocean circulation continues to slow down and warning signs are beginning to identify what the world likes in the coming decades.

Researchers at the Swire Institute of Marine Sciences and Hong Kong University studied sediment and fossils off the Canadian coast to recreate the ocean circulation in the past and where it is today. The team, who published his findings in Geophysical Research Letters, detect dramatic dilution of sea circulation in the last century.

The weakening of the sea circulation, in particular the Atlantic Ocean Revolution (AMOC), is causing concern to North America and Europe for the future. To understand what we can expect in the future, researchers look to the past for analogues.

Looking At The Past To Understand The Future

In the past, scientists have reported dramatic events of the name Heinrich Events. Heinrich's event is the sudden and large-scale cut and ancient glacial houses across North Atlantic. It is believed that these events are linked to a number of Ice Age events, which occur at 5 last and last seven years of ice on Earth dating back to 640,000 years.

Scientists believe we could be in a similar situation today, where cutting and paying glaciers and glaciers in the North Atlantic and the Greenland could cause large freshwater input into North Atlantic. This sudden input of fresh water causes a cap to the global AMOC circulation.

The key engine for AMOC's ongoing flow is the sinking of cold water and arrow in North Atlantic. As salty water moves to the north of the tropics it cools and becomes relatively intense than nearby water. This cold water and arrow dries to the bottom of the North Atlantic and begins to flow to the south again along the bottom of the sea. This causes more tropical water from the tropics to flow to the north and the circle continues. This circulation of thermohaline is what scientists fear scare because of the fresh water cap that melts ice in North Atlantic.

As AMOC slows down, it can have dramatic consequences for North America and Europe's special climate and weather. AMOC works to transfer extensive quantities of ocean heat from tropics to northern latitudes. Without this transport belt from warm water to the north, North of North America and Europe will suffer from conditions cooler.

AMOC regulates a global climate and works to distribute heat more equally around the world. Without this mechanism in place, seasonal rainfall and temperature will be changed to fit the new ocean / atmosphere scenario.

Yes Ice AgeWikipedia

Researchers refer to the latest scenario that looks like what we are experiencing today, the Yes Ice Age. This period, which ranges between 1300 and 1850 AD, marks bitter cold conditions in Europe, famine, drought, and common decline in the population. A nbsp; although scientists are uncertain about the precise mechanism that came to this cold period, a strong assumption is the high melting of the North Atlantic ice spread and slow down the sea circulation later.

Although modern technology can help cope with long-term climate variations, the effects on the economy and health will inevitably be. As the global climate continues to change, we can look at history as a blueprint for what can bring climate models for what could be around the corner.

Researchers refer to the latest scenario that looks like what we are experiencing today, the Small Ice Age. This period, which ranged between 1300 and 1850 AD, marked bitter cold conditions in Europe, famine, drought, and the general deterioration of the population. Although scientists are uncertain about the precise mechanism that has been brought at this cold time, a leading assumption is to dissolve the high North Atlantic broadcaster and slow down the circulation of the sea later.

Although modern technology can help cope with long-term climate variations, the effects on the economy and health will inevitably be. As the global climate continues to change, we can look at history as a blueprint for what can bring climate models for what could be around the corner.
