Climate change refers to significant alterations 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.
- 2Human activities such as deforestation and industrial processes contribute significantly to greenhouse gas emissions.
- 3Climate change results in extreme weather events, rising sea levels, and biodiversity loss.
- 4Mitigation strategies include reducing emissions, transitioning to renewable energy, and enhancing carbon sinks.
- 5Adaptation measures are necessary to cope with the impacts of climate change on communities and ecosystems.
Simple Explanation
Climate change means that the Earth's climate is changing, mostly because of things people do, like burning coal and oil. This causes gases to build up in the atmosphere, trapping heat and making the planet warmer. As a result, we see more extreme weather, rising sea levels, and problems for animals and plants. To help, we need to reduce our emissions and find ways to adapt to these changes.
