Grinnell Glacier shrinkage — Climate change A series of photographs of the Grinnell Glacier taken from the summit of Mount Gould in Glacier National Park, Montana, in (from left) 1938, 1981, 1998, and 2006. In 1938 the Grinnell Glacier filled the entire area at the bottom of the image. By 2006 it had largely disappeared from this view.

The primary distinction between weather and climate lies in their time scales. Weather refers to the atmospheric conditions at a specific location over a short period, such as daily temperature, humidity, wind, and precipitation. Climate, conversely, describes the average atmospheric conditions over much longer periods, typically 30 years or more, for a given region. While weather can change from hour to hour, climate represents the more stable, long-term patterns. Understanding this difference is crucial, as climate change, which involves shifts in these long-term averages, can have more severe consequences than short-term weather fluctuations.12345
