The violent nature of explosive volcanic eruptions makes understanding their behavior both imperative and extremely challenging. These dangerous natural phenomena threaten society in a variety of ways ranging from destruction of local communities to disrupting global air traffic to influencing global climate change. Our ability to mitigate the risks posed by volcanoes is hampered by our limited understanding of their controlling physics. The opacity and violence of eruptions makes them difficult and dangerous to measure directly.

Climate models are used to understand the complex interactions that result in climate change as well as provide projections of future climate change and its impacts on society. I will give a broad overview of current climate and Earth system models, including the diversity of algorithms represented, the complexity of the models and their application to both science and policy problems. Future demands on climate model applications as well as a changing computing landscape will require rethinking the design and implementation of our models.
