5. 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

6. 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
