Local Actions, Global affects Global warming debate Learning Objectives • To outline the arguments for and against global warming • To understand other possible reasoning for temperature increase • To evaluate evidence that proves and disproves the theory Global Warming Investigation • • • • • • • • • • 1. What is Global warming? In section 1, describe and explain what global warming is and how it works. 2. Are humans to blame? In section 2, explain the arguments connecting the influence of human actions and the increased risk of global warming. 3. Is it really just nature? In section 3, examine and explain arguments that disagree with human actions and the increased risk of global warming are being influenced from another source. 4. What is the future going to be like? In section 4, describe, explain and evaluate the potential effects of increased global warming in the future, including social, environmental and economic effects 5. In my opinion, I think…. In section 5, evaluate and conclude your own opinion on why global warming may be happening and the effects for the future. In this section also include what can be done to combat global warming and how successful you think each of these plans will be. Global Warming assignment level requirements Level 5 targets/requirements Pupil teacher Pupil teacher Explain how global warming works Begin to include balanced arguments for and against global warming being a result of human influence Explain implications and effects of global warming Suggest ways to combat global warming in the future Level 4 targets/requirements Describe what global warming is Outline how humans produce CO2 State some of the side effects of global warming Describe the effects of global warming Level 6 targets/requirements Pupil teacher Pupil teacher Describe and comment on the uneven distribution of CO2 around the world and explain why Include graphs, diagrams and/or graphs to support arguments in your assessment In detail, outline the social, economic and environmental effects of increased temperature on the globe, including positive and negative examples Explain how plans to combat global warming will work and evaluate how successful each will be, including sustainable development for the developing world and future Level 7 targets/requirements Recognise the causes and consequences of environmental issues and understand a range of views about them and different approaches to tackling them Explain what and whom influences decisions over CO2 production around the world and why CO2 emissions are unlikely to decrease in the short term Give and explain case studies of examples of global warming occurring now that support or disprove the global warming debate Evaluate critically both DVDs and other sources of evidence to support your final conclusion Examine, explain and conclude the social, economic and environmental issues connected to global warming and develop how each aspect interacts with one another. Considerations of sustainable development can affect their own lives as well as the planning and management of environments and resources Use the matrix to record and assess your progress My evaluation of my assignment Below in the box provided you need to write what you have done well in this assignment and what you think you need to improve upon. At the end of the self assessment you will need to grade yourself a level. Pupil Comments: GRADE You will level your own work Teacher Comments: Targets You will self assess your work and comment on what you have done well and what you could do to improve it. GRADE How will I do this? • This is independent learning. • You will research global warming using text books, “Data sheets”, the internet and your notes from the videos that you have been shown. • You will prepare a detailed report following the writing frame, ticking off the tasks as you complete them. • You will self evaluate your work. • You will either hand write or word process your report (Using Word) to hand in P5 4th July. • You can use computers in HU2 on Thursday lunchtimes. Where will I find out what I need? • Geog 2 Page 78-79- Basic info on causes and effects • Connections Page 6- Basic info • Green house effect data sheets • Effects of global warming data sheets • The internet • Using the library in your own time.

What is Global warming? In section 1, describe and explain what global warming is and how it works. Gases in the atmosphere such as carbon dioxide, methane, nitrous oxides and CFC’s (Greenhouse gases) trap the radiation from the sun that is reflected back from the Earth. Source: Solcomhouse.com Greenhouse Effect • The gases in the atmosphere act like a blanket around our planet which traps in heat, making the temperature rise. • This is called the Greenhouse Effect and is a natural process that keeps the planet warm and sustains life. • If the greenhouse effect didn’t exist, the average temperature on earth would be around -18ºC. solcomhouse.com Is global warming really happening? • What evidence is there that global warming is happening? • We can look at changes in temperature, Sea levels, large pieces of Ice, known as Glaciers and Ice caps • You will need to draw out the grid like the next slide and then watch the next 3 video clips – make notes on each section. • Temperatures Sea Levels Evidence of climate change Glaciers Ice Caps Figure 1: Photographs taken from the same point of a South American glacier Figure 2: Photographs taken from the same point of a glacier in the USA What Is The Evidence Of Global Warming? Polar Ice Caps Glacial Retreat Rising Sea Levels 2. How are humans responsible for producing more Carbon Dioxide? • • • • • What are the major sources of carbon dioxide production? Burning fossil fuels Factories Having lots of cars on the road Cutting down trees For this question, you need to make the points, give examples to support your points and then explain with as much detail as possible Are Humans to blame? In this question you are answering yes – You must now use PEEEL to explain, give reasons and explore why this is the case TO answer this question think and consider the following things for your response – How has life for Humans changed in the last 100 years? What influence and impact have Humans had on the amount of Carbon Dioxide being produced and why is this important? • • • • • • • • • • • • How and why has this change happened – Increased standard of living and how. Increased demand and use for natural resources Increased electricity use Increased heating Changes in Food around the world Use of transport Increased holidaying Development and changes in industry Use and demand of fossil fuels Destruction of the rainforest / Deforestation World population change • • • • How do these things influence and change carbon dioxide Explain, Explore, give examples and evidence and evaluate Are these changes equal across the world? Are some countries / people more responsible than others. Q3. Is it just nature? In this question, you are required to give evidence and explanation showing that the warming of the Earth is due natural reasons and not humans. • 4 clear reasons why the Earth is warming due to natural causes • 1. The output of the sun’s energy changes • 2. The orbit of the Earth around the sun changes • 3. The tilt of the Earth alters making it closer and further away from the sun • 4. The natural wobble of the Earth causes it to become closer to the Sun. • Evidence to support this – • Historically how has climate changed with no input from humans? TO support with this question we will watch the clip about natural causes again and then short clip from the global warming DVD Influences on causes of climate change • The key areas are – • The Sun: Variations in Solar Output • Variations in the Earth’s orbit • Variations in the Earth’s tilt Some scientists believe that the global warming we are seeing has natural causes… • The Sun: Variations in Solar Output • Variations in the Earth’s orbit • Variations in the Earth’s tilt The history of climate change.
