The left panel shows the greenhouse effect, where heat is trapped near Earth’s surface by naturally occurring greenhouse gases. The right panel shows how humans are intensifying the greenhouse effect through processes that release greenhouse gases into the atmosphere, mainly burning fossil fuels for energy and transportation.

Human-produced greenhouse gases have intensified Earth's natural greenhouse effect by changing the balance between the amount of sunlight that reaches the surface and the amount of heat that escapes the atmosphere. CREDIT: NOAA Climate Program Office, Graphic by Anna Eshelman
