Thinner Arctic sea ice may affect the AMOC, say scientists

Global surface warming enhanced by weak Atlantic overturning circulation

Evidence from palaeoclimatology suggests that abrupt Northern Hemisphere cold events are linked to weakening of the Atlantic Meridional Overturning Circulation (AMOC)1, potentially by excess inputs of fresh water2. But these insights—often derived from model runs under preindustrial conditions—may not apply to the modern era with our rapid emissions of greenhouse gases. If they do, then a weakened AMOC, as in 1975–1998, should have led to Northe…

Thinner Arctic sea ice may affect global ocean circulation

One of the ocean currents in the Arctic Ocean is at risk of disappearing this century because of climate change, according to a new study. As a result, the North Atlantic could be flooded with freshwater which would weaken the global ocean circulation.

Arctic Alarm: Thinning Ice Could Tip Global Ocean Currents Into Chaos

A major ocean current in the Arctic, the Beaufort Gyre, is changing rapidly due to climate warming—and this could trigger a chain reaction that disrupts the Atlantic Meridional Overturning Circulation (AMOC), the system behind the Gulf Stream. Scientists warn that melting sea ice may reach a tipping point, causing the Gyre to release massive amounts [...]

Thinner Arctic sea ice may affect the AMOC, say scientists

One of the ocean currents in the Arctic Ocean is at risk of disappearing this century because of climate change, according to a new joint study from the University of Gothenburg and the German Alfred Wegener Institute. As a result, the North Atlantic could be flooded with freshwater, which would weaken the global ocean circulation.

A simulation on the origin and evolution of the North Atlantic Oscillation (NAO) was conducted by a PKU research team led by Nie Ji, Associate Professor of the School of Physics; and Hu Yongyun, Dean of the Ocean Research Institute, as well as a research team from the National Natural Science Foundation of [...]

PKU Researchers Model the Origin and Evolution of the North Atlantic

A groundbreaking study, recently published in the esteemed journal Nature Communications, has unveiled significant insights into the origin and evolution of the North Atlantic Oscillation (NAO). Conducted by a team of researchers from Peking University, led by Associate Professor Nie Ji from the School of Physics, and Dean Hu Yongyun from the Institute of Ocean Research, the research represents a pivotal advancement in understanding how geologic…
