There is a clear need for exascale to help us better understand the coming climate crisis. The UN Intergovernmental Panel on Climate Change (IPCC) has reported that the effects of climate change are advancing more quickly and with far greater impacts than models predicted only a few years ago.
It is a significant challenge to model the interactions of water, temperature, atmospheric gasses and sunlight, among thousands of dynamic and variable factors. It requires expending enormous analytical power on vast data sets.
With the world’s fastest supercomputers and state-of-the-art visualisation tools, it is possible for climate scientists to create simulations of the Earth’s air, water and land systems on a global scale.
These models provide invaluable guidance as to how to reduce the degree of climate change the Earth faces. They can also help us to predict future changes with extraordinary speed and precision. Finally, exascale systems can aid us with forecasting the impact of climate change on our communities, infrastructure and energy use, helping us to plan for future scenarios.
