What's the difference between climate change and global warming? (Climate Change FAQ #2)

Climate change is defined as a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.

Global warming, in contrast, a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.

In general, “global warming” refers to the long-term warming of the planet - a well-documented rise since the early 20th century, particularly since the late 1970s. Worldwide, since 1880 the average surface temperature has gone up by about 0.8 °C (1.4 °F), relative to the mid-20th-century baseline (of 1951-1980).

“Climate change” includes global warming as well as many other changes Earth is undergoing.such as rising sea levels, shrinking mountain glaciers, accelerating ice melt in Greenland, Antarctica and the Arctic, and shifts in flower/plant blooming times. These are all consequences of the warming, which is - in turn - caused mainly by people burning fossil fuels and putting out heat-trapping gases into the air.

The terms “global warming” and “climate change” are sometimes used interchangeably, but they technically refer to slightly different things.

  1. Thanks for adding quite a few blog posts. In the future, please make clear connections between your posts and your project. It is unclear to me how this related to photovoltaics, for example.
