2. Climate change Climate change is caused by the release of greenhouse gases like carbon dioxide into the atmosphere. Fossil fuels like coal, oil and gas are made of carbon so release lots of carbon dioxide when they are burnt. WWF’s Earth Hour 2011 PowerPoint for secondary schools

3. Climate change Most of the world’s electricity is produced by burning coal, many of our homes are heated by fossil fuels and nearly all of the world’s vehicles are powered by burning oil. Therefore every time we use electricity, heat our homes or use a car it contributes to the effects of climate change. WWF’s Earth Hour 2011 PowerPoint for secondary schools

4. Climate change: Effects Climate change is already a really serious problem for humans and animals. It is causing polar ice to melt and sea levels to rise. It is causing seasonal weather patterns to change and increasing extreme weather events like floods and droughts. WWF’s Earth Hour 2011 PowerPoint for secondary schools

5. Climate change: Effects All these changes are making it more difficult than ever for endangered animals. It also makes life harder for humans: extreme weather is causing drought and flooding in many parts of the world, making it more difficult to produce food, or even just to survive. WWF’s Earth Hour 2011 PowerPoint for secondary schools

6. Climate change: What can we do? There are lots of small changes which we can make to help to tackle climate change. Can you suggest any? WWF’s Earth Hour 2011 PowerPoint for secondary schools

7. Climate change: What can we do? Here are a few changes we could make: Walk or cycle instead of driving to school. Switch televisions and computers off instead of leaving them on standby. Put on a jumper when you are cold instead of turning on the heating. Make sure to recycle all plastic, paper and glass instead of throwing it away. Turn off the lights when you leave a room. WWF’s Earth Hour 2011 PowerPoint for secondary schools

8. Climate change: WWF’s Earth Hour It’s important that we all do our bit by making small changes to our lifestyle. However, it is also important that we tell important people like the government and big businesses that we think climate change is important.

9. Climate change: WWF’s Earth Hour One way of doing this is by taking part in WWF’s Earth Hour. On the 26 th March 2011, WWF is asking everyone to switch off their lights for 60 minutes. In 2010 hundreds of millions of people from over 128 countries joined in to make the biggest statement ever about climate change. WWF’s Earth Hour 2011 PowerPoint for secondary schools

10. Climate change: WWF’s Earth Hour Hundreds of famous buildings and landmarks also switched off their lights in a show of support. Do you recognise these buildings and landmarks? WWF’s Earth Hour 2011 PowerPoint for secondary schools

11. Climate change: WWF’s Earth Hour Can you tell me what these famous buildings are? WWF’s Earth Hour 2011 PowerPoint for secondary schools

16. Climate change: WWF’s Earth Hour This year we want to make the event even bigger; the world’s largest display of hope for a bright future. We will be celebrating WWF’s Earth Hour at school, but you can help by also passing the message to your friends and family and asking them to get involved.
