Vision of Research
A new and transformative data-driven approach that:• Makes use of wealth of observational and simulation data• Advances understanding of climate processes• Informs climate change impacts and adaptation
Research Overview
Research Highlights
Research Overview
Climate change is the defining environmental challenge facing our planet, yet there is considerable uncertainty regarding its social and environmental impact This Expeditions project addresses key challenges in the science of climate change by developing methods that take advantage of the wealth of climate and ecosystem data. These innovative approaches help provide an improved understanding of the complex nature of the Earth system and the mechanisms contributing to the adverse consequences of climate change. Methodologies developed as part of this project will be used to gain actionable insights and to inform policymakers.
Education/Outreach Activities• Undergraduate and graduate courses and programs at the intersection of climate and data sciences• Cross disciplinary training environment• Extensive research opportunities for students from historically underrepresented groups• Fostering interdisciplinary collaborations by organizing workshops and sessions at climate and computer science venues• Engagement with UNEP and IPCC
