The document discusses energy and climate change. It defines energy and different types of energy sources, distinguishing between non-renewable sources like fossil fuels and renewable sources like solar, hydropower, and wind. It then defines climate and climate change, listing some of the main causes of climate change like greenhouse gases. The document outlines several indicators of climate change and impacts, such as rising sea levels, increasing temperatures, extreme weather events, and effects on ecosystems and human society.

2. • Energy
Energy is the quantitative property that is transferred to a body or a
physical system, recognized in the performance of work.
• The law of conservation of
energy

3. Types of Energy
 Non-renewable energy: Non replenish (fossil fuels, nuclear energy,
etc)
 Renewable energy: Replenish (Solar, Hydropower, wind, Biomass,
etc)

7. Climate
 Climate is the long-term weather pattern in an area, typically
averaged over 30 years.
Climate Change
 When temperature and weather pattern is shifted then it is
known as climate change also global change.

8. Cause of Climate Change
 Heat-trapping Greenhouse Gases.
 Reflectivity or Absorption of the Sun's Energy.
 Changes in the Earth's Orbit and Rotation.
 Variations in Solar Activity.
 Changes in the Earth's Reflectivity.
 Volcanic Activity.

9. Climate Change Indicator
 Global warming
 Changes in polar and glacial ice
 Rising sea level and ocean acidity
 Changing wind and weather patterns
 Health and society
 Changing ecosystem

10. Impact of Climate Change
 Global Change

11. Impact of Climate Change
 Sea level is rise for ice
melting
 Increasing temperature
 Costal area go under water
 Increasing water acidity

12. Impact of Climate Change
 Extreme drought
 Decline in crop productivity
 heavy rainfall across the
globe

13. Impact of Climate Change
 Changing Ecosystem

14. Impact of Climate Change
 Geological Hazard like Hurricanes,
Floods, Turnado, etc.
