Any changes in ocean currents affect the ocean's ability to absorb carbon dioxide (which is affected by water temperature) as well as ocean productivity because the currents transport nutrients (see Impacts on phytoplankton and net primary production). Because the AMOC deep ocean circulation is slow (it takes hundreds to thousands of years to ...
[19] [20] [21] Ocean currents play a significant role in influencing climate, and shifts in climate in turn impact ocean currents. [20] Human-induced climate change is leading to long-term alterations in ocean and atmospheric circulation.
As such, the state of the circulation has a large impact on the climate of the Earth. The thermohaline circulation is sometimes called the ocean conveyor belt, the great ocean conveyor, or the global conveyor belt, coined by climate scientist Wallace Smith Broecker. [5] [6] It is also referred to as the meridional overturning circulation, or ...
A system of ocean currents that transports heat northward across the North Atlantic could collapse by mid-century, according to a new study, and scientists have said before that such a collapse ...
In recent years, studies have shown that the current is at its weakest in 1,000 years. ... head of the Marine Physics and Ocean Climate group at the National Oceanography Centre, ...
When the fate of an ocean current system tops headlines during a historic heat wave, it’s a strange week for climate science. Climate collapse debate reinvigorated by study of Atlantic ocean ...
Impacts will include cooling of Northern Europe faster than 3°C per decade, "with no realistic means of adaptation". At the same time, the Antarctic Circumpolar Current (ACC) is also slowing down and the Weddell Sea Bottom Water is losing volume, what can impact global ocean circulation and climate. [142]
By 2050 it expected to lose 20% of its strength with "widespread impacts on ocean circulation and climate." The Weddell Sea Bottom Water has lost 30% of its volume in the latest 32 years, and the Antarctic Bottom Water is expected to shrink. This will impact ocean circulation, nutrients, heat content and carbon sequestration. [22]
