Cause of Extreme North Atlantic Warming in 2023 with Matthew England

In this Climate Chat episode, we interview University of New South Wales climate scientist Matthew England on his recent Nature paper "Drivers of the extreme North Atlantic marine heatwave during 2023." We will also discuss Matthew's research on the Atlantic Meridional Overturning Circulation (AMOC) and changes in the Southern Ocean circulation and its impact on Antarctica. Matthew England is Australia’s leading ocean modeller and the world’s foremost authority on the modelling of the Southern Ocean. He was the first to successfully capture Antarctic water-masses in global climate models. England is also one of the world’s leading scientists in the modelling of deep ocean ventilation using tracers: he pioneered the use of geochemical and age tracers, and was the first to use CFCs to assess ocean model skill. England has also changed our view of the ocean’s role in regional climate variability and climate dynamics, with a particular focus on the Southern Hemisphere and climate over Australia.
