basically the way the atmosphere is behaving, mainly with respect to its
effects upon life and human activities. The difference between weather and
climate is that weather consists of the short-term (minutes to months)
changes in the atmosphere. Most people think of weather in terms of
temperature, humidity, precipitation, cloudiness, brightness, visibility,
wind, and atmospheric pressure, as in high and low pressure.
What's the Difference Between Weather and Climate?
When we talk about climate change, we talk about changes in long-term averages of daily weather. Today, children always hear stories from their parents and grandparents about how snow was always piled up to their waists as they trudged off to school. Children today in most areas of the country haven't experienced those kinds of dreadful snow-packed winters, except for the Northeastern U.S. in January 2005. The change in recent winter snows indicate that the climate has changed since their parents were young.
If summers seem hotter lately, then the recent climate may have changed. In various parts of the world, some people have even noticed that springtime comes earlier now than it did 30 years ago. An earlier springtime is indicative of a possible change in the climate.
