Climate Change
Climate refers to the long-term average of weather conditions in a particular region. Unlike weather, which changes daily, the Earth’s climate evolves gradually over thousands of years due to natural influences such as variations in solar radiation, volcanic activity, or ice ages.
What is Climate Change?
Climate change refers to any long-term shift in temperature, precipitation, wind patterns, or other elements of the Earth’s climate system. While natural factors have always played a role in changing the climate, current changes are largely driven by human activities.
This includes:
- Burning fossil fuels (like coal, oil, and natural gas)
- Industrial emissions
- Deforestation (which reduces carbon absorption)
These activities increase the concentration of greenhouse gases in the atmosphere, altering the Earth’s energy balance and leading to global changes in climate patterns.
Understanding the Difference: Weather vs Climate
- Weather describes the atmospheric conditions on a particular day.
- Climate is the average pattern of weather over a long period (typically decades).
For instance, Jammu may have a sunny day in winter, but its climate generally includes cold days with snow and rain. If these long-term patterns change, such as fewer snowy winters, it indicates climate change.
Measuring Climate Change
Climate change is detected by observing:
- Rising global temperatures
- Altered precipitation patterns
- Increased frequency of extreme weather events
- Long-term trends in wind, snow, and rainfall patterns
