Climate is what we expect, weather is what we get. Climate refers to the average weather conditions in a certain place over many years. For example, the climate in Minnesota is cold and snowy in the winter, and the climate in Honolulu, Hawaii, is warm and humid all year long. The climate in one area, like the Midwest or Hawaii, is called a regional climate. The average climate around the world is called global climate. When scientists talk about global climate change, they're talking about the global climate and a pattern of change that's happening over many years.
Time factor in climate and weather. The difference between weather and climate is a measure of time. Weather refers to the atmospheric conditions of a specific place over a short period of time, usually 24 hours. Climate refers to the average atmospheric conditions over relatively long periods of time, usually 30 years. In other words, when one talks about the climate, then they're talking about the pattern over a long term while when weather is referred to then the conditions of short term are being spoken of.
