Climate change refers to changes in average weather patterns such as temperature, wind, and precipitation over extended periods of time. Climate change has occurred naturally in the past due to factors like changes in the Earth's orbit and sun's energy output, as well as volcanic eruptions. However, the current climate change is also influenced by human activities that have increased greenhouse gas emissions such as the burning of fossil fuels, deforestation, and industrial processes. If unmitigated, climate change will have widespread effects on systems like weather, ecosystems, agriculture, and sea level rise.

2. WHAT IS CLIMATE CHANGE?
• Is natural phenomenon and has been occurring since the earth
came into being. And is a change in the average weather of a
given area or region. This includes temperature wind patterns,
and precipitation. This change is referred to in global sense
and concenrs the earth as a whole.
