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
Arman Alluwie TP2 SHSS
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
Arman Alluwie TP2 SHSS
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?
Arman Alluwie TP2 SHSS
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 …

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
Arman Alluwie TP2 SHSS
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
