We present results from detailed interviews with 12 leading climate scientists about the possible effects of global climate change on the Atlantic Meridional Overturning Circulation (AMOC). The elicitation sought to examine the range of opinions within the climatic research community about the physical processes that determine the current strength of the AMOC, its future evolution in a changing climate and the consequences of potential AMOC changes. Experts assign different relative importance… 
Expert judgments about transient climate response to alternative future trajectories of radiative forcing
TLDR
Face-to-face interviews with 14 leading climate scientists revealed that over the next 20 years research will be able to achieve only modest reductions in their degree of uncertainty, with “cloud radiative feedbacks” contributing most to their uncertainty about future global mean temperature change.

Early warning signals of Atlantic Meridional Overturning Circulation collapse in a fully coupled climate model
TLDR
It is shown that early warning signals of AMOC collapse are present in a fully coupled atmosphere-ocean general circulation model, subject to a freshwater hosing experiment, and the statistical significance of signals of increasing lag-1 autocorrelation and variance vary with latitude.
Expert judgements of sea-level rise at the local scale
Whilst local projections of sea-level rise (SLR) are necessary to facilitate targeted climate change adaptation and communication strategies, downscaling from global climate models can be
Global Warming and a Potential Tipping Point in the Atlantic Thermohaline Circulation: The Role of Risk Aversion
The risk of catastrophes is one of the greatest threats of climate change. Yet, conventional assumptions shared by many integrated assessment models such as DICE lead to the counterintuitive result
Emissions corridors for reducing the risk of a collapse of the Atlantic thermohaline circulation
In this paper, we present the integrated assessment model dimrise (dynamic integrated model of regular climate change impacts and singular events). This model is designed to investigate the stability
On the driving processes of the Atlantic meridional overturning circulation
Because of its relevance for the global climate the Atlantic meridional overturning circulation (AMOC) has been a major research focus for many years. Yet the question of which physical mechanisms
North Atlantic observations sharpen meridional overturning projections
Atlantic Meridional Overturning Circulation (AMOC) projections are uncertain due to both model errors, as well as internal climate variability. An AMOC slowdown projected by many climate models is

Collapse and rapid resumption of Atlantic meridional circulation linked to deglacial climate changes
TLDR
It is found that the meridional overturning was nearly, or completely, eliminated during the coldest deglacial interval in the North Atlantic region, beginning with the catastrophic iceberg discharge Heinrich event H1, 17,500’yr ago, and declined sharply but briefly into the Younger Dryas cold event, about 12,700 yr ago.
