Data & Computing are cross-cutting MCSC focus areas. Our data focus revolves around the opportunity found in data to manage and develop climate and sustainability solutions. Researchers from all fields are encouraged to contribute to a collaborative data environment where data can be easily discovered and enhanced by modern data fusion and hybrid computing methods and techniques. A mixture of data pools and data warehouse architecture can enable flexibility at scale for heterogeneous datasets. On the computing side, critical framing to our work is that within the next decade computing and communications is predicted to consume more than 20% of the world’s electricity coupled with significant impact on materials and chemical use, as well as waste generation. This burden is juxtaposed with the tremendous benefits from computing capability that will be critical to rapidly and broadly decarbonizing energy use and mitigating pressures on planetary boundaries.
