Climate change refers to significant changes in global temperatures and weather patterns over time. While climate change is a natural phenomenon, human activities have accelerated this process, leading to severe environmental impacts.
Key Concepts
- 1The greenhouse effect and its role in global warming.
- 2Human activities contributing to climate change, such as burning fossil fuels and deforestation.
- 3Impacts of climate change, including rising sea levels, extreme weather events, and biodiversity loss.
- 4Mitigation strategies to reduce greenhouse gas emissions.
- 5Adaptation measures to cope with the effects of climate change.
Simple Explanation
Climate change is when the Earth's average temperature increases due to gases in the atmosphere trapping heat. This is mainly caused by human activities like burning coal, oil, and gas, which release carbon dioxide. As a result, we see changes in weather patterns, more extreme weather, and rising sea levels. It's important to find ways to reduce these emissions and adapt to the changes that are already happening.
