What is Impacts of Climate Change?
Within Earth & Environmental Science, which covers our planet, its resources and ecosystems, and how people can protect the environment, this topic explains Impacts of Climate Change. Earth and environment topics show how the planet’s systems shape landscapes, climate and life, with models that make these processes visible.
Check that you can explain Impacts of Climate Change in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Impacts of Climate Change helps you explain the environment around you and weigh up how people can protect it.
Impacts of Climate Change in detail
Climate change affects natural and human systems. Rising temperatures cause heatwaves, melting glaciers and ice caps, and sea level rise from meltwater and thermal expansion, threatening coastal cities and small island states. Rainfall patterns change, with more intense storms and floods in some places and droughts in others.
Ecosystems are affected: coral reefs bleach, species move or face extinction, and seasons shift. People face risks to food and water supplies, health, homes and livelihoods, and some may migrate. Impacts are uneven, with poorer regions often most affected despite contributing least. Without action, risks increase with each degree of warming.
How the interactive helps you understand Impacts of Climate Change
Watch the bar chart in the interactive. Use any sliders or buttons it offers to change the values and see how the bar chart responds.
Before you change anything, predict the result. Then change one value at a time and check whether your prediction was right. This is a quick way to build a correct mental model of Impacts of Climate Change.
Real-life uses and examples
- Use a diagram of Impacts of Climate Change to describe the steps of a process in order.
- Discuss how human activity changes Impacts of Climate Change, using a named example.
- Explain how Impacts of Climate Change affects the landscape or climate near you.
Common mistakes to avoid
- Describing a process without the timescale it works over.
- Presenting one cause as the only cause of an environmental change.
- Learning the definition without testing it. Use the quiz and the interactive to check that you can apply the idea.
