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 it, leading to serious environmental impacts.
Key Concepts
- 1The greenhouse effect is caused by gases trapping heat in the Earth's atmosphere.
- 2Human activities, such as burning fossil fuels and deforestation, increase greenhouse gas emissions.
- 3Climate change leads to rising sea levels, extreme weather events, and loss of biodiversity.
- 4Mitigation strategies include reducing carbon emissions and transitioning to renewable energy sources.
- 5Adaptation strategies help communities adjust to the impacts of climate change.
Simple Explanation
Climate change is when the Earth's climate becomes warmer due to increased greenhouse gases in the atmosphere. This happens mainly because of human activities like burning coal, oil, and gas. As a result, we see more extreme weather, rising sea levels, and changes in ecosystems. It's important to take action to reduce these effects and adapt to the changes.
