3+Geography Class Test: CA2

11th of April 2012 Wednesday, Double Period

Topics Tested Chapter 6 Elements of Weather (page 87- 108) part of Chapter 7 Types of Climate (page 117)


4+Lesson Objectives

By the end of the week, we would have discussed the climate changes in the last 200 years


5+An Inconvenient Truth: Trailer


6+Climate Change:What do we know?

7+Climate Change:What do we know?



8+Climate Change:A Quick Disclaimer Climate change is an undergoing study

facts and figures are highly debated amongst scientists and interest groups

no common consensus on a governing authority on climate change

Intergovernmental Panel on Climate Change requires the benefit of time


9+Climate Change

is a shift in the average weather conditions that a region experiences over a long period of time cold stages (glacial periods) warm stages (interglacial periods)

So what’s the concern? speed of temperature change has increased coincides with dramatic increase in carbon dioxide

levels

natural process whereby greenhouse gases absorb heat from the Sun’s rays and trap it in the atmosphere “transparent blanket”: allowing light to pass through

but trapping heat

greenhouse gases carbon dioxide, water vapour, nitrous oxides and

methane

average temperature of 15°C

Enhanced Greenhouse Effect:Revising the Greenhouse Effect

13+Enhanced Greenhouse Effect

More greenhouse gases released and trapped

Global Warming Rise in Earth’s average global temperature


Industrial Revolution

CO2 by 30%Nitrous Oxides

by 15%

CH4 by 150%


14+Enhanced Greenhouse Effect:Causes

1. Industrial Activities

2. Large Scale Deforestation

3. Agricultural Activities

Enhanced Greenhouse Effect:Industrial Activities


17+Enhanced Greenhouse Effect:Industrial Activities advancements in technology has increased the

scale of human activities in the use of fossil fuels in vehicles, factories and

power plants

interconnectedness has increase the spatial impact of human activities how do you get your Norwegian Salmon?


18+Enhanced Greenhouse Effect:Large Scale Deforestation reduced the amount of vegetation cover

less carbon dioxide is absorbed from the atmosphere

cleared for timber and mining, to create land for other activities such as agriculture and urban development

19+Enhanced Greenhouse Effect:Agricultural Activities Not something new however the food industry

brings some concerns …

21+Enhanced Greenhouse Effect:Causes

1. Industrial Activities

2. Large Scale Deforestation

3. Agricultural Activities


22+Enhanced Greenhouse Effect:Can we stop?


23+Effects of Climate Change

1. Melting Ice and Rising Sea Levels

2. Extreme Weather Conditions1. Severe Storms

2. Heat Waves and Droughts

3. Impact on Plants and Animals

26+Melting Ice and Rising Sea Levels glaciers are retreating and the amount of ice cover

has decreased in the polar regions

melting of this frozen stores of water has caused sea levels to rise

low-lying coastal countries are especially vulnerable to rising sea levels


27+Extreme Weather Conditions

higher global temperatures increase evaporation rates resulting in higher relative humidity

in rainfall

warmer ocean temperatures cause more intense (both frequency and strength) tropical storms September- October 2005: 3 Major Hurricanes
