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 these changes, leading to severe environmental impacts.
Key Concepts
- 1Greenhouse gases trap heat in the atmosphere, leading to global warming.
- 2Climate change causes extreme weather events, such as floods, droughts, and hurricanes.
- 3Rising sea levels threaten coastal communities and ecosystems.
- 4Climate change impacts biodiversity, leading to species extinction.
- 5Mitigation and adaptation strategies are essential to manage climate change effects.
Simple Explanation
Climate change is when the Earth's temperature rises because of gases like carbon dioxide that trap heat in the atmosphere. This can cause problems like more severe storms, rising sea levels, and changes in where plants and animals can live. Humans contribute to climate change mainly by burning fossil fuels for energy.
