Objectives Understand what causes global warming Be able to explain how different variables affect global warming

What do you know?

Global warming (climate change) Increasing amounts of carbon dioxide in the _ _ _ _ _ _ _ _ _ _ mean more _ _ _ _ is trapped, making the Earth warmer

Factors affecting climate change Amount of greenhouse gases (CO 2, CH 4 etc.) Amount of snow cover Plants using up CO 2. More CO 2 makes plants grow quicker Changing ocean currents carrying heat

Effects of climate change Some areas get hotter, some colder – Problems with crops – Problems for animals and plants Changes in amount of rain Glaciers and ice caps melting – Raising of sea level More storms

Flowchart Create a flowchart to show how variables interact to affect climate change
