Ecological and Societal Impacts of Marine Heatwaves

Session ID#: 253495

Session Description:
Marine heatwaves (MHWs) are increasingly recognized as pervasive stressors in the ocean. Globally, their frequency and intensity are rising, predominantly as a consequence of anthropogenic climate change. MHWs are emerging as important drivers of environmental change, impacting marine species and ecosystems, the industries they support and the services they provide. It is important to identify and understand the ecological and societal impacts of MHWs to accurately inform stakeholders and policy makers, and to develop adaptation strategies. This session aims to highlight recent advances in our knowledge of the effects of MHWs. We invite abstracts that examine the biological, ecological or societal impacts of MHWs, as well as studies that explore potential adaptation strategies to reduce the impacts of further events.
