And just like that we're free from climate hysteria and worried about a new "ice age"...Funny how that works, isn't it?

The Post writes that the study argues that warming temperatures are melting the Greenland ice sheet, sending freshwater into the North Atlantic and slowing the AMOC. Researchers say they’ve detected a related “distinctive temperature fingerprint” several thousand feet below the surface.

“Here we identify a distinctive temperature fingerprint in the equatorial Atlantic that signals the Atlantic Meridional Overturning Circulation change,” they wrote, adding that its “robust physical mechanism and reliable detection make [this fingerprint] a valuable metric for AMOC monitoring in a warming climate.”

Using the MITgcm climate model and ocean data back to 1960, the team concludes the AMOC has been weakening since the late 20th century and could collapse before 2100. If that happened, Europe could face drastic cooling — possibly nearly 60 degrees — and drier conditions. As Jonathan Bamber told the Daily Mail, “Winters would be more typical of Arctic Canada and precipitation would decrease, also.”

Climate models project an Atlantic Meridional Overturning Circulation slowdown under anthropogenic greenhouse warming. Despite a ~1.5 °C increase in the global mean surface temperature, debate remains on whether and when this circulation has slowed. Here we identify a distinctive temperature fingerprint in the equatorial Atlantic that signals the Atlantic Meridional Overturning Circulation change through numerical ocean model experiments. The equatorial Atlantic is a crucial crossroads for the circulation anomalies to propagate to other oceans. A slowdown drives a mid-depth (1000–2000 m) warming in the equatorial Atlantic in a decade via baroclinic Kelvin waves. Analysis of climate models shows that this mid-depth temperature change is a better indicator for Atlantic Meridional Overturning Circulation change on decadal and longer timescales than other surface proxies. Observations reveal a robust mid-depth warming since 1960 that emerged from natural variability in the early 2000s, suggesting a slowdown that already started in the late 20th century.

The Atlantic warming pattern driven by the subpolar buoyancy forcing change is linked to the coherent circulation changes through the thermal-wind relationship, manifested as basin-scale weakening of meridional overturning circulation. Changes in circulation reduce the northward warm-water transport of the upper-limb AMOC and the southward cold-water transport of the deep-limb AMOC, resulting in heat convergence near the western coasts in the mid and low latitudes. These rapid adjustments of subsurface temperature and circulation are through Kelvin waves excited by subpolar buoyancy forcing.

In addition, the equatorward heat transport by the climatological deep western boundary current (DWBC) also contributes to the mid-depth equatorial warming. We perform a BUOY-NA-passive experiment, which is the same as BUOY-NA but with the fixed ocean circulation. In BUOY-NA-passive, the perturbed ocean temperature change in the North Atlantic and Arctic Oceans travels as passive tracers via the mean ocean circulation (see Methods). The results of BUOY-NA-passive suggest that the mean DWBC leads to a weak deep-layer warming in the western equatorial Atlantic after about half a century, and has minimal contribution to the quick mid-depth warming.

Transient greenhouse warming

We further examine the statistical relationship between changes in the equatorial Atlantic temperature and AMOC intensity of the North Atlantic using the 50-member Large Ensemble of the Community Earth System Model version 2 (CESM2-LENS) under the historical and Shared Socioeconomic Pathways (SSP) 3–7.0 scenarios (Fig. 3). Temperature in the equatorial Atlantic shows pronounced multi-decadal fluctuations during the historical period and has warmed up in the upper 3000 m since the 1990s (Fig. 3a). Like BUOY-NA, there is a vertical minimum in warming albeit at ~500 m in CESM2-LENS. This could be due to forcing difference; forcing is abruptly switched on in BUOY-NA, while CESM2-LENS uses slowly evolving radiative forcing that includes both anthropogenic greenhouse gases and aerosols.

Western Universities have been grossly overproducing unemployable overeducated graduates for decades. These scary Anthropogenic Global Warming / Anthropogenic Global Cooling articles by “Climate Scientists” are all part of government-funded make work programs for otherwise unemployable university graduates. It’s just another form of Universal Basic Income.
