Climate change refers to significant changes in global temperatures and weather patterns over time. While climate change is a natural phenomenon, human activities, particularly the burning of fossil fuels, have accelerated this process, leading to severe environmental impacts.
Key Concepts
- 1Greenhouse gases trap heat in the atmosphere, contributing to global warming.
- 2Human activities, such as deforestation and industrial processes, increase greenhouse gas emissions.
- 3Climate change leads to extreme weather events, rising sea levels, and loss of biodiversity.
- 4Mitigation strategies include reducing emissions, transitioning to renewable energy, and enhancing energy efficiency.
- 5Adaptation measures involve adjusting practices and infrastructure to minimize the impacts of climate change.
Simple Explanation
Climate change is when the Earth's climate changes, often getting warmer due to human activities like burning coal and oil. This warming causes problems like more intense storms, rising sea levels, and changes in where plants and animals can live. People are trying to solve this by using cleaner energy and changing how we live to protect the planet.
