The terms “global warming” and “climate change” are sometimes used interchangeably, but strictly speaking they refer to slightly different things. Global warming refers to the warming of the Earth over longer time periods. Due to documentations of global temperature, an increase is observed since the early 20th century and especially since the late 1970s. A worldwide average temperature increase of around 1°C has been documented since 1880, relative to the mid-20^th-century baseline (of 1951 – 1980). This is on top of an additional 0.15 °C of warming from between 1750 and 1880.

Climate change on the other hand includes global warming but refers to the larger range of environmental changes. These changes include rising sea levels, retreating mountain glaciers and accelerating ice melt in Greenland, Antarctica and the Arctic.
