The Greenhouse Effect – Dr. Patrick Nunn (Geography Dept, University of the South Pacific)

Abstract

This is an educational audio presentation by Dr. Patrick Nunn of the University of the South Pacific’s Geography Department. In it, he explains the fundamentals of the greenhouse effect—how greenhouse gases like CO₂ trap heat in Earth’s atmosphere—and outlines its critical role in moderating global temperatures. Dr. Nunn connects this science to the Pacific context, discussing the region’s vulnerability to rising temperatures, sea-level rise, and changing weather patterns. He emphasizes the importance of understanding the greenhouse effect for local climate adaptation strategies and policy planning across Pacific Island nations, drawing on research and climate modeling relevant to the South Pacific.
