The Greenhouse Effect and Global Warming Climate Change Facts, Opinions, Debate and Action

Objectives MUST: recall some of the key facts of The Greenhouse Effect and Global warming SHOULD: be able to describe a number of ways of dealing with CO2 emissions COULD: be able to explain the challenges for society in tackling the issue of global warming and it’s potential effects

Facts

CO 2 is a greenhouse gas (the more there is, the more it traps Solar Energy)

Facts CO 2 is a greenhouse gas (the more there is, the more it traps Solar Energy) Human Activities, mostly involving fuel use, add large quantities of CO 2 to the atmosphere

What can be done? Should something be done?

What can Scientists do? Debate and Discuss Use Arguments from Authority Find ways to reduce CO 2 : Emissions - Energy Use Containing and Reducing Atmospheric CO 2

How to Reduce CO2 Cut Emissions - Energy Efficiency, Restrictions on Energy use (Taxes on Cars?) Carbon Neutral – Plants trees, plants, to remove CO 2

Arguments Deductive Arguments = reasoning from the general to the specific Inductive Arguments = reasoning from specific observations to a broader generalisation Arguments from Authority = Opinion offered by an expert on the basis of their knowledge... Arguments from Analogy = Reasoning based on percived similarities.... Casual Arguments = These claim that something has happened as a direct result of something else occurring previously....

Climate Change – What can be done?

Tackling Climate Change Carbon Footprint Carbon Neutral Energy Efficiency

Tackling Climate Change Reduce Fuel Use Increase Energy Efficiency Reducing Deforestation / Planting more Trees Carbon Capture and Storage

Problems Associated with Tackling Climate Change Costly – Economic Slowdown Personal Demands and Comforts Demands for raw materials and expanding population
