• Global Warming Has Accelerated: Are the United Nations and the Public Well-Informed? (2025) · Environment Science and Policy for Sustainable Development · cited 171× · doi

  As of today, the threats of AMOC shutdown and sea level rise are poorly understood, but better observations of polar ocean and ice changes in response to the present accelerated global warming have the potential to greatly improve our understanding.

• North Atlantic response to a quasi-realistic Greenland meltwater forcing in eddy-rich EC-Earth3P-VHR hosing simulations (2026) · Ocean science · doi

  The majority of studies on the impact of freshwater from ice sheet melting on the AMOC use climate models that cannot resolve mesoscale ocean processes. These models do not include an accurate spatio-temporal distribution of the freshwater forcing, which critically affects the nature of the AMOC response.

• North Atlantic response to a quasi-realistic Greenland meltwater forcing in eddy-rich EC-Earth3P-VHR hosing simulations (2026) · Ocean science · doi

  The simulation length is limited to 21 years. The ensemble size is relatively small, with only three members. The study acknowledges that the moderate but consistent AMOC weakening might not be sufficient to drive large-scale, strong impacts on the global climate.

• Volcanic eruptions caused weakening AMOC during the preindustrial past millennium (2026) · Nature Communications · doi

  The mechanisms of AMOC weakening during the preindustrial past millennium have remained uncertain. The impact of volcanic eruptions on AMOC has not been well understood. The study of AMOC using paleo data and climate models has been limited.

• Failure to track a stable AMOC state under rapid climate change (2026) · Nature Climate Change · doi

  The study identifies a gap in our understanding of the dependence of AMOC stability on the rate of radiative forcing change. Prior work has focused on estimating the global warming threshold for AMOC collapse, but the study argues that this threshold may not be meaningful.

• Failure to track a stable AMOC state under rapid climate change (2026) · Nature Climate Change · doi

  Further research is needed to investigate the potential impacts of rapid climate change on the AMOC. The study suggests that more accurate climate models and predictions are needed to inform climate policy and mitigation strategies. Future research should focus on the development of more sophisticated climate models that can accurately capture the dependence of AMOC stability on the rate of radiative forcing change.
