Paper: Attributing Venice Acqua Alta events to a changing climate and evaluating the efficacy of MoSE adaptation strategy

Read the paper: This research employs an innovative approach by utilizing analogues of atmospheric patterns to scrutinize four notable Acqua Alta events in the Venice lagoon, specifically those connected with intense Mediterranean cyclones that transpired in 1966, 2008, 2018, and 2019. The findings provide compelling evidence that modifications in atmospheric circulation, while not solely attributable to human activities, are undeniably linked to the increased severity of these events, thereby illuminating the vulnerability of Venice to the impacts of climate change. Furthermore, the study conducts a comprehensive assessment of the MoSE system, a crucial adaptation infrastructure designed to mitigate flooding in Venice, and underscores its effectiveness in protecting the city against events with historical analogues, particularly those akin to the catastrophic 1966 flood.

Paper: Heat Extremes in Western Europe warmed faster than simulated

Extract from the article, Figure 3.

Read the paper: Over the last 70 years, extreme heat in Western Europe has intensified with 3.4°C per degree global warming. A rate much larger than nearly anywhere else. Very few models capture the observed trend. None of them captures the large contribution from trends in atmospheric circulation.
The mismatch can be due to an underestimated circulation response to external forcing or underestimated unforced internal variability, or both. The former implies that heat extremes continue to intensify at an extreme rate, the latter that the trend continues but may slow down.
