Although the terms global warming and climate change are often used interchangeably, they apply to different phenomena. Climate change refers to changes in Earth’s temperature, humidity, air pressure, wind, clouds, and precipitation patterns over time. Global warming is a contributing factor to climate change and refers specifically to the effect of greenhouse gases on Earth’s average surface temperature. When discussing rising temperatures caused by greenhouse gases, global warming is an acceptable term. However, climate change is the more accurate term when describing other long-term changes to the planet’s weather patterns. The term global warmingfirst appeared in geochemist Wallace Broecker’s 1975 Science magazine article, “Climatic Change: Are We on the Brink of a Pronounced Global Warming?”(Opposing Viewpoints)
