I chat about a vital, must read peer-reviewed scientific paper linked here:

The Weakened Atlantic Meridional Overturning Circulation Diminishes Recent Arctic Sea Ice Loss
https://agupubs.onlinelibrary.wiley.c....

I mentioned this paper near the end of my last video; but this paper importance clearly merits a full video and discussion.

“Abstract
The Arctic sea ice has been rapidly dwindling over the past four decades, significantly impacting the Arctic region and beyond. During the same period, the Atlantic meridional overturning circulation (AMOC) was also found in a declining trend. Here we investigate the role of the AMOC in the recent Arctic sea ice changes by comparing simulations from the Community Climate System Model version 4 with decelerated and stationary AMOCs under anthropogenic climate change. We find that the weakened AMOC can slow down the decline rates of Arctic sea ice area and volume by 36% and 22% between 1980 and 2020, respectively. The decelerated ocean circulation causes a reduction of northward Atlantic heat transport and hence a general interior ocean cooling in the Arctic Mediterranean, which helps alleviate the Arctic sea ice loss primarily through thermodynamic processes occurring at the base of the sea ice.

Key Points
This study clarifies the AMOC's impact on Arctic sea ice by using the CCSM4 climate model simulations with weakened and stationary AMOCs

The weakened AMOC could decelerate the Arctic sea ice area and volume loss by 36% and 22% during 1980 and 2020, respectively

Detailed sea ice volume budgets shows weakened AMOC promotes ice growth at base, aided by thermodynamic process”

Bottom line:
“We find that the weakened AMOC can slow down the decline rates of Arctic sea ice area and volume by 36% and 22% between 1980 and 2020, respectively.”

I think that AMOC slowing over recent decades has prevented us from having the first Blue Ocean Event (BOE). If the AMOC strength had stayed constant, I think that we would live in a world with many BOE’s occurring on a regular, maybe yearly basis.

Moving forward, we may see a BOE followed by AMOC spin-down and a deep freeze Arctic with strengthened zonal jet streams with less waviness.

Or if the AMOC slowdown passes a threshold in its spin-down decline first, the Arctic would chill and a BOE would be indefinitely postponed.
