Abstract

The idea of energy balance used to explain the greenhouse effect and global warming is often confusing for students, primarily because the standard quantitative analysis uses many constants and units. A "round" unit method is presented, which maintains the quantitative aspects of the standard analysis, but is much more intuitive for students.
