Data-driven research on the Earth's historical climate and the impact of energy production on modern climate change.
grantProject GreenLight
This project, developing an instrument called GreenLight, measures, monitors, and optimizes the energy consumption of large-scale scientific applications from many different areas.
mediaUC San Diego’s GreenLight Project To Improve Energy Efficiency Of Computing – Photonics Online
The information technology industry consumes as much energy and has roughly the same carbon “footprint” as the airline industry. Now scientists and engineers at the University of California, San Diego are building an instrument to test the energy efficiency of computing systems under real-world conditions — with the ultimate goal of getting computer designers and users in the scientific community to re-think the way they do their jobs.

publicationGreening the Internet in a Carbon-Constrained World – Xconomy
This year marks a turning point in the debate on global climate change. The focus of the discussion is rapidly moving from a scientific analysis of how human activity affects climate change to a political process on how best to regulate greenhouse gas (GHG) emissions.
