How heat is impacting human health: Professionals Advocating for Climate Action in conversation with Professor Ollie Jay

​As temperatures rise, we're experiencing more extreme weather (eg bushfires), poorer air quality, changes in infectious diseases and growing heat-related deaths.

​Workplaces need to adapt and mitigate to the changing climate and weather. From work health and safety to economic and financial implications, our organisations need to take proactive steps in being ready for the changing climate.

​In this online session, Professor Ollie Jay will be joining Professionals Advocating for Climate Action, to explain the key findings of the recently released Lancet Countdown report, which outlines the latest science on heat and human health and recommended priorities to enable a healthy, thriving future.

​In addition to being a co-author of this respected report, Ollie is Professor of Heat and Health and Director of the Heat and Health Research Centre and Thermal Ergonomics Laboratory in the Faculty of Medicine, University of Sydney.
