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
• CO2 is a greenhouse gas (the more there is, the more it traps Solar Energy)
• Human Activities, mostly involving fuel use, add large quantities of CO2 to the atmosphere
Facts
• CO2 is a greenhouse gas (the more there is, the more it traps Solar Energy)
• Human Activities, mostly involving fuel use, add large quantities of CO2 to the atmosphere
• CO2 levels are increasing
Facts
• CO2 is a greenhouse gas (the more there is, the more it traps Solar Energy)
• Human Activities, mostly involving fuel use, add large quantities of CO2 to the atmosphere
• CO2 levels are increasing
• Average Global Temperatures are increasing
Opinions or Arguments from Authority?
• The Rise in CO2 levels is causing Global Warming
• Global Warming is responsible for Climate Change
Opinions or Arguments from Authority?
• The Rise in CO2 levels is causing Global Warming
• Global Warming is responsible for Climate Change
• Climate Change is responsible for the extreme weather in recent years
Opinions or Arguments from Authority?

• Climate Change will.....
What can Scientists do?
• Debate and Discuss• Use Arguments from Authority
• Find ways to reduce CO2:• Emissions - Energy Use• Containing and Reducing Atmospheric CO2
How to Reduce CO2
• Cut Emissions - Energy Efficiency, Restrictions on Energy use (Taxes on Cars?)
• Carbon Neutral – Plants trees, plants, to remove CO2
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....
Tackling Climate Change
• Reduce Fuel Use
• Increase Energy Efficiency
• Reducing Deforestation / Planting more Trees
• Carbon Capture and Storage
