Dame Julia Slingo served as Chief Scientist of the U.K. Met Office from 2009 to 2016 when she retired. Throughout her research career she has developed and used complex weather and climate models to understand the climate system and to predict its evolution. Her special
interests are in tropical weather and climate variability, understanding their influence on the global climate system and their role in monthly to decadal climate prediction. Climate change will be one of the defining challenges of the twenty-first century; how we respond will determine our future prosperity, health and well-being and the sustainability of Earth’s natural environment. However, these responses must be underpinned by the best possible climate science to ensure that we make wise decisions on how to build resilience to weather and climate extremes, and adapt to and mitigate climate change. In this talk, Dame Julia Slingo will discuss the history of our understanding of how the climate system works, how this understanding has been embedded in the development of climate models, and how we use these models now to guide our actions to deliver a safe and sustainable future.
