Overview
• Main conflict over project statement• Global warming’s relationship to climate change• Ways of answering our project statement– Agreement– Disagreement
• Mitigation versus Adaption– Strategies– Consequences
• Conclusion
![Page 3: ‘Global warming is inevitable; we should therefore concentrate our efforts on accommodating its effects’. Comment. Ryan Jarriel, Juan Mattioli, Tom Fryer.](https://reader035.fdocuments.net/reader035/viewer/2022062422/56649f0c5503460f94c205cc/html5/thumbnails/3.jpg)
Central Conflict
• Different viewpoints of agreement– We are already too late to prevent climate change– A moral rather than an economic issue
• The potential benefits outweigh the known costs• Monetization problem: a lot of costs of continuing current trends don’t
have a monetary value
• Different viewpoints of disagreement– Doesn’t believe in global warming– Doesn’t believe immediate response is necessary– Believes the planet can handle our global warming– NIMBY

Global Warming
• The Greenhouse Effect– Greenhouse Gases• Water vapor, ,
• Defining Climate Change
CO2
NH4,NOX ,O3,&CFCs
“A change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to
natural climate variability observed over comparable time periods.”
- UN Framework Convention on Climate Change

Scientific Fact vs. Uncertainty
Known
• Greenhouse effect governs global temperature
• The risks of consequences
Unknown
• How much warming?
• Timescale of effects

Agrees with the statement
• Indicators of climate change(a) 10 hottest years on record
![Page 8: ‘Global warming is inevitable; we should therefore concentrate our efforts on accommodating its effects’. Comment. Ryan Jarriel, Juan Mattioli, Tom Fryer.](https://reader035.fdocuments.net/reader035/viewer/2022062422/56649f0c5503460f94c205cc/html5/thumbnails/8.jpg)
Agrees with Statement
(b) Ice Core Drilling• concentration relation to temperature
CO2
![Page 9: ‘Global warming is inevitable; we should therefore concentrate our efforts on accommodating its effects’. Comment. Ryan Jarriel, Juan Mattioli, Tom Fryer.](https://reader035.fdocuments.net/reader035/viewer/2022062422/56649f0c5503460f94c205cc/html5/thumbnails/9.jpg)
Agrees with Statement
Hurricane Katrina failure• Evacuation delay• The poor suffer first• Twisted values
– Costs• $105 billion for repairs and reconstruction• $41.1 billion for the insurance industry• Oil production loss• 1,836 deaths
![Page 10: ‘Global warming is inevitable; we should therefore concentrate our efforts on accommodating its effects’. Comment. Ryan Jarriel, Juan Mattioli, Tom Fryer.](https://reader035.fdocuments.net/reader035/viewer/2022062422/56649f0c5503460f94c205cc/html5/thumbnails/10.jpg)
Agrees with the statement
• Problems with a passive approach– Population Redistribution: Marshall Islands– Nonmonetary: Loss of biodiversity
![Page 11: ‘Global warming is inevitable; we should therefore concentrate our efforts on accommodating its effects’. Comment. Ryan Jarriel, Juan Mattioli, Tom Fryer.](https://reader035.fdocuments.net/reader035/viewer/2022062422/56649f0c5503460f94c205cc/html5/thumbnails/11.jpg)
Opposes the statement
• Global cooling is too expensive• Unfair distribution of cost– China & India problem
• Scaremongering on the effects– Hurricane Katrina– Exaggerated consequences
![Page 12: ‘Global warming is inevitable; we should therefore concentrate our efforts on accommodating its effects’. Comment. Ryan Jarriel, Juan Mattioli, Tom Fryer.](https://reader035.fdocuments.net/reader035/viewer/2022062422/56649f0c5503460f94c205cc/html5/thumbnails/12.jpg)
Mitigation
• Definition: The attempt to reduce the potential effects of global warming by altering mankind’s behaviour in such a way that reduces our contribution to rising global temperatures.
• Risk-minimization approach– Underlying concern: do we have the resources?
![Page 13: ‘Global warming is inevitable; we should therefore concentrate our efforts on accommodating its effects’. Comment. Ryan Jarriel, Juan Mattioli, Tom Fryer.](https://reader035.fdocuments.net/reader035/viewer/2022062422/56649f0c5503460f94c205cc/html5/thumbnails/13.jpg)
Mitigation
• Risk-Minimization– Justifying expenditures as insurance
Low or certain probability (x) Catastrophic consequences (=) Major risk to society
![Page 14: ‘Global warming is inevitable; we should therefore concentrate our efforts on accommodating its effects’. Comment. Ryan Jarriel, Juan Mattioli, Tom Fryer.](https://reader035.fdocuments.net/reader035/viewer/2022062422/56649f0c5503460f94c205cc/html5/thumbnails/14.jpg)
Mitigation
• A shift in the status quo– Incentive policies– Cost of sustainability
• Side Benefits– Economic: Energy services– Environmental: Urban air pollution, acid rain– Social: Land reform, reforestation

Mitigation
– Overlapping cost– “Luxury fever”– Scarcity of rare earth
metals
• Un-sustainability & Global Warming

Adaption
• Definition: Reducing the vulnerability of natural and human systems in order to reduce the potential impact that climate change has on us
• Wait-and-see approach– Underlying concern: the cost of preventing what?
• Global temperatures & world wealth
![Page 17: ‘Global warming is inevitable; we should therefore concentrate our efforts on accommodating its effects’. Comment. Ryan Jarriel, Juan Mattioli, Tom Fryer.](https://reader035.fdocuments.net/reader035/viewer/2022062422/56649f0c5503460f94c205cc/html5/thumbnails/17.jpg)
Adaption
• Can potentially take extreme forms• Stern Report (2006) - £3,680,000,000,000

Adaption
• Runaway Greenhouse Effect
![Page 19: ‘Global warming is inevitable; we should therefore concentrate our efforts on accommodating its effects’. Comment. Ryan Jarriel, Juan Mattioli, Tom Fryer.](https://reader035.fdocuments.net/reader035/viewer/2022062422/56649f0c5503460f94c205cc/html5/thumbnails/19.jpg)
Adaption/Mitigation
• Costs of mitigation = immediate• Costs of adaptation = long term• Costs of mitigation = calculated• Costs of adaptation = speculative
Developing economies see it differently
![Page 20: ‘Global warming is inevitable; we should therefore concentrate our efforts on accommodating its effects’. Comment. Ryan Jarriel, Juan Mattioli, Tom Fryer.](https://reader035.fdocuments.net/reader035/viewer/2022062422/56649f0c5503460f94c205cc/html5/thumbnails/20.jpg)
Conclusions
• Mitigation > Adaption• Gradual changes to industry– Policy changes & consumer preference• Agriculture• Automotive• Water systems
– Brownfield land example• Previously used derelict or contaminated land• 60% of new developments on brownfield by 2008

Conclusions
“The era of procrastination, of half-measures, of soothing and baffling expedients, of delays, is coming to its close. In its place we are entering a period of consequences.”
– Sir Winston ChurchillNov 12, 1936
