Developed by a team of scientists from two national laboratories, education researchers, gamers, and a professional game developer, Challenge and Persuade is a highly social, fast-paced, fun-to-play card game in which players compete in applying skills in argumentation. Through game play, players come to understand the many manifestations of how the extreme amplification of the human population—exploding worldwide demand for energy, increasing exploitation of water resources, and alteration of the planet's climate—are tightly intertwined at the nexus of energy, water, and climate; one cannot be considered in isolation from the other two. Development was supported by the National Science Foundation.
