Increased risk of near term global warming due to a recent AMOC weakening

Rémy Bonnet (IPSL) will talk about his recent publication: https://www.nature.com/articles/s41467-021-26370-0

This study investigates the influence of the multi-centennial variability of the global mean surface temperature found in some of the new generation CMIP6 climate models. Using an ensemble of climate simulations, we show that simulations with the smallest rates of global warming since the middle of the 20th century are also those with a large internally-driven weakening of the Atlantic Meridional Overturning Circulation (AMOC). These simulations also matches several AMOC observational fingerprints, which are in line with such a weakening. This suggests that internal variability from the Atlantic Ocean may have dampened the magnitude of global warming over the historical era.

What is a climate coffee?

Climate coffees are relaxed meetings for scientists to exchange ideas, discuss about their latest results and new methods with their fellow scientists.

Climate coffees are an initiative of ECRA and Blue-Action.
