Understanding Weather, Climate, and Climate Change

What is Weather?

Weather refers to the short-term atmospheric conditions in a specific place at a given time. It includes a variety of phenomena such as temperature, humidity, precipitation, wind, and visibility. Weather can change rapidly; for instance, one might experience sunny skies in the morning and thunderstorms in the afternoon. Such variations can occur within minutes or hours.

Climate Definition

In contrast to weather, climate describes the average atmospheric conditions over an extended period, typically 30 years or more. It provides a broader perspective on what kind of weather patterns one might expect in a particular region. For example, a region may have a tropical climate characterized by high temperatures and heavy rainfall, or a polar climate with cold temperatures and minimal precipitation.

The Concept of Climate Change

Climate change, on the other hand, refers to significant, long-term changes in average temperatures and weather patterns, primarily driven by human activities such as greenhouse gas emissions. While natural processes contribute to climate variations, the current trend of climate change poses serious environmental concerns. Unlike the short-term fluctuations seen in weather, climate change has profound implications for ecosystems, sea levels, and global temperatures.
