Study Notes
Climate Change
- Climate change is not a new phenomenon, as the Earth's climate has always been subject to changes in temperature and rainfall patterns.
- In the past, these changes were primarily driven by natural events, but human behavior is now a significant contributor to climate change.
Human Impact on Climate Change
- The increasing number of cars and aeroplanes over the last 50 years has contributed to climate change.
- Increased energy consumption in daily life, including heating, lighting, travel, and entertainment, has also played a role.
- Burning fossil fuels like coal and oil to generate energy releases carbon dioxide into the atmosphere, leading to a rise in global temperatures.
Consequences of Climate Change
- The increased production of carbon dioxide has led to a significant rise in global temperatures.
- Emissions from cars and aeroplanes are trapped by the ozone layer, contributing to the Earth's rising temperature.
