The document discusses climate change and global warming. It defines climate change as long-term shifts in weather patterns due to natural and human causes that lead to changes in temperature, precipitation, and other factors. The natural causes are listed as solar output, volcanic activity, and variations in Earth's orbit. The human causes are identified as the increased burning of fossil fuels and deforestation, which raise carbon dioxide levels. The document outlines the debate around whether global warming poses a serious threat or is a natural phenomenon, and suggests student activities like dividing into groups to discuss causes and solutions, and developing a class project focused on environmental protection.

- 2. What is Climate Change ? ● Long-term shift in weather conditions ● Leads to changes in temperature, rain, snow, wind and other factors ● Result of natural and human causes 2
- 3. What are the Natural Causes? Solar Output Volcanic Activity 3 Earth's Orbit around the Sun
- 4. What are the Human Causes? Increase Burning of Fossil Fuels Deforestation Carbon Dioxide Smoke Belching 4
- 5. Global Warming Increase in the average temperature of the Earth's atmosphere and oceans caused by increasing concentrations of greenhouse gases (such as Carbon Dioxide) Do you see a pattern on the graph? 5
- 6. The Debate on Global Warming It's not serious... We should act now! ● No scientific ● Human activities evidence causes the increase ● Global warming is in CO2 natural ● Increase in the ● We need carbon world temperature dioxide will affect water, food and climate 6
- 7. Activity The class will be divided in groups of 4 and will have to fill out a big cartolina with the following information below. They will report this after 20 mins. 7
- 8. Video Resource The Truth About Global Warming - Science & Distortion – by Stephen Schneider http://www.youtube.com/watch?v=4_eJdX6y4hM This is a video of Stephen Henry Schneider (February 11, 1945 – July 19, 2010). He was Professor of Environmental Biology and Global Change at Stanford University, a Co-Director at the Center for Environment Science and Policy of the Freeman Spogli Institute for International Studies and a Senior Fellow in the Stanford Woods Institute for the Environment. He was awarded a Nobel pea The Intergovernmental Panel on Climate Change (IPCC), to which Schneider made very significant contributions, shared in the 2007 Nobel Peace Prize. 8
- 9. Project: What can you do to help? 1. Ask the class what they can do to help the environment to save the earth from global warming. 2. Come up with a project that the class can do and document like: ● Earth Hour (turn off the lights for an hour from 7PM to 8PM) ● Recycle (gather plastic bottles and papers in school and segregate them) ● Tree Planting (find a place, reservoir, where the children can plant seedlings) 3. Ask them to write about their experience on this. 9
