When you hear the word “clean”, many things may come to mind. Here in the Department of Earth System Science (ESS) at UC Irvine we think, “Climate, Literacy, Empowerment And iNquiry” – CLEAN. In 2008, ESS graduate students founded CLEAN with the goal of teaching the science behind the effects of climate change in a positive and empowering way. CLEAN Education presenters visit local classrooms leading hands-on, grade-appropriate lessons about water, the carbon cycle, endangered species, and greenhouse gases. Their goal is to equip future generations with the knowledge to understand and deal with a changing climate. Since they started, forty CLEAN Education presenters have given more than one hundred presentations.
