1. LO: To be able to interpret graphs to explain if the climate is changing To be able to construct a diagram to show the greenhouse effect To explain the natural causes of climate change To explain the human causes of climate change

3. How has the Earth's average surface temperature changed in the last 1000 years?

4. Total emissions of CO 2 from fossil fuel burning

8. Homo Sapiens Industrialisation

9. Watch the video clip…. Using the information complete a table to explain the human and natural causes of climate change

10. Global Warming Causes Negative Impacts Solutions Positive Impacts

11. Solar Energy Reflected by the atmosphere into space. Solar energy heats Earth. Earth radiates heat. GREENHOUSE GASES Heat is retained by greenhouse gases and warms the atmosphere- Global Warming Heat lost to space

12. GREENHOUSE GASES Deforestation means less Carbon Dioxide is taken in, some trees are burnt releasing Carbon Dioxide. Farming rice and cattle releases methane. Greenhouse gases increase. More heat is trapped, warming the Earth. Burning fossil fuels releases Carbon Dioxide.
