| What is climate change? |
| When people talk about climate change, they usually mean recent changes, or expected future changes, in the Earth's climate. |

These changes could affect all parts of the world, but in different ways. In the UK, climate change is already leading to:
- more frequent heatwaves and fewer frosts,
- more rain but on fewer days - which means more storm damage and flash floods, and
- a 10cm higher sea level around the UK than in 1900.
The largest single cause of climate change is the use of fossil fuels like oil and gas. It works like this:
 |
1. |
Burning fossil fuels to generate electricity releases gases such as carbon dioxide
(a "greenhouse gas") into the atmosphere. |
 |
2. |
Greenhouse gases help keep more heat in the Earth's atmosphere (global warming). |
 |
3. |
Global warming leads to climate change. |
|
 |
Greenhouse gases are released whenever we use our gas or electrical household appliances - like the TV, cooker, washing machine or electric lights - when we drive a car or fly in a plane, and when we do dozens of other things in our everyday lives.
Many scientists believe we have to cut greenhouse gas emissions over the next 10-20 years to prevent extreme climate change. By changing some of these things we do now, we won't reverse what has already happened, but we can help to change what happens in the future.
