Reason for increase in CO2 concentration.
The global human population is growing and becoming more socially complex.
41
Example of intentionally confusing the public.
Confusion between weather and climate by Donald Trump in tweets about a cold spell in America to deny global warming.
42
How do humans effect CO2 levels?
Fires, deforestation, agriculture and burning fossil fuels. These things majoring increased during the industrial revolution.
43
The Anthropocene is what?
A name for a possible new geological era, marked by human activity.
44
Three sceptic arguments are?
The industrial revolution is only 0.000004% of the Earths 4.6 billion years. CO2 concentrations have been higher in the past, this is true but they haven't beem higher in the last 400,000 years. The earth has been warmer in the past, this is also true however we were in a Cenozoic cooling period until now.

4 main ones, all showing different outcomes.
50
What is computational climate modelling and how can it improve?
This modelling works with complex mathematical equations based on well established physical laws defining the behavior of weather and climate. If this physical laws are better understood and computer power increases then modelling accuracy will increase.
51
What is Hindcasting?
This is predicting the climate of recent years to test the accuracy of modelling.
52
Testing climate models by?
Hindcasting, short term predictions and running multiple models.
53
Where will warm fastest?
The poles.
54
Maslin predicts a warming of what?
1.1-6.4 degrees.
55
Maslin predicts a sea level rise of what?

``` Queensland floods (Jan 2011) Cylclone Yasi (Jan 2011) Wildfires (Feb 2009) ```
63
Africa is vulnerable to climate change, why?
It is underdeveloped, high population density, a change in rainfall levels would have a dramatic effect.
64
Canada has positive and negative effects to its above average warming rate, what are they?
Negative: A reduction in snow/ice has implications for ecosystems, e.g. polar bears and whales. The Tundra melting is releasing large amounts of methane. Positive: Longer growing season and increased tourism. They are a developed country so may be able to cope better than others.
65
Climate change effects on the UK.
The winters will be wetter, so flooding will increase, summers will be dryer and warmer, heatwaves can be difficult to manage and deadly for the elderly and infants.

72
How will we know a countries coping range?
By analysing their response to climatic stresses.
73
What is the IPCC a partnership between?
The scientific community and the worlds governments.
74
What does the IPCC do?
Assesses the evidence on climate change and it impacts, gives adaptation/mitigation options. Brings together peer review literature.
75
Is there a measure to the terminology used by the IPCC
Yes, e.g. High confidence = at least a 9 out of 10 chance of being correct.
76
Warming will increase extreme weather events, does the IPCC agree with this statement?
Yes. Climate change is loading the dice for negative events to happen.
77
Crisicisms of the IPCC are?
Some believe it is too conservative and the effects will be worse than they say, others pick out any small error and use it to dismiss the arguments made by the IPCC. Some question the relevance of the reports compared to other pressing issues in the world.
78
Is climate change sceptisim going away?
No, it is on the rise - this could be due to blogs and twitter becoming more popular so inaccurate facts can be spread more easily.
79
Drivers of climate sceptisim are?
Sceptics like Nigal Lawson spreading his opinion although it differs from the assessment of experts. Argues that phasing out fossil fuels is morally unfair to developing countries. Climategate increased sceptisims even though there was no dishonesty found. Many sceptic groups out there funded by fossil fuel companies.
80
How are scientists fighting climate change sceptisim?
Releasing official statements on their views of climate change. Interacting with the public more.
81
What is industry?

21%
83
There is a debate on where the responsibility lies within industry, who is this between?
Production (direct) or consumption (indirect)
84
How has industries perspective on climate change changed over time?
Originally most industry was united against climate change. $2 billion spent 2000 - 2016 against climate change legislation. Companies and NGOs now have partnerships. ENGOs put pressure on companies to be more climate friendly. Climate change seen less of a threat but more of an opportunity.
85
What does BINGO stand for?
Business and Industry Non-Governmental Organisation.
86
How long have BINGOs been included offically in climate conferences?
Since 2000
87

88
Reactionary BINGOs are?
Claim global warming is over exaggerated, offered $10,000 to any article that emphasized short comings of the IPCC. Favour taxing consumers over industry. E.g. American Enterprise Institute.

Difference between reactive and proactive responses to climate change.
Reactive - Trying to slow change and seeing it only as a negative. Proactive - Exploiting the opportunities and supporting the environmental regulation.
94
Origin of ENGOs

95
What does ENGO stand for?
Environmental Non-Governmental Organisation.
96
Shells plans to dispose of an oil platform at sea.
Greenpeace led a successful boycott against this, this method of naming and shaming is used often and works well.

114
The first IPCC report suggested that what would be effected by climate change?
Socio-economic effects.

1-1.5% of GDP for developed countries on damage. 2-9% of GDP for developing countries. 1.5-2% of world GDP.
116
Why is it hard to put a price on climate change?
It is hard to combine different models, social costs and economic concepts.
117
Why can pricing climate change be seen as offensive?
Pricing up the damage and cost often put poorer countries as worth less per life lost.

140
What are the three main models used by the IPCC?
PAGE (1195), DICE (1991) and FUND (2001). All give a good starting point for pricing carbon.

An international treaty. Annex 1 parties that are legally bound met a 5% reduction target. China and the USA drove the continued rise.
144
How are there differentiated responsibilities for making a change?
Some countries emmited more GHGs, are wealthier and have better capacity to make the reductions.
145
Kyoto protocol criticisms
Allowed countries to develop carbon markets, weak, minor impacts,limited financial support, opposition.
146
The Paris agreement replaced the Kyoto protocol, what is this?
A clear goal not to let global temperature rise above 2 degrees, countries determine their own targets, legally binds participants to track progress. Aim for a global market for carbon pricing.

It is expensive to monitor and enforce. Lots of unknowns.
150
What does ETS stand for?
Emissions Trading System.
151
What was the first large scale tradable quota system in the world?
The EU emissions trading system. A trading system. 28 countries. Covers CO2, N2o and PFCs (Perflurocarbons)
152
EU ETS phase 1
Phase 1: 2005-2007, 43% of EUs emissions, only cover CO2, the allowances were free, government awarded permits.
153
Pigouvian tax is what?
A tax to correct the costs not included in the price of a good, externalities.
154
An emissions tax can be upstream or downstream, what does this mean?
Either at the production/extraction or downstream to the consumer. Rising the cost of something to discourage it.
155
What is personal carbon allowances?
PCA is a per capita idea, everyone can only use so much carbon, people less likely to spend on CO2 intensive products.
156
There are differential preceptions of climate change, what does this mean?
The concern for climate change is different in different regions. What the concern is about also varies.
157
Do countries that are wealthy and rely on fossil fuels the most concerned?
No, their concern for climate change tends to be lower.
158
What is the information deficit hypothesis?
Gap between scientific community understanding of climate change and public – simply requires more communication.
159
Peoples concern about climate change was growing till the 2000s, then what grew with it?
Scepticism. There was then a decline in the perceived seriousness of the matter.
160
Is the precieved risk of climate change and political polarisation linked?
Yes. American Democrats have more climate change concern than Republicans.
161
How is climate change different to previous environmental challenges?
The complexity kills policy making, unsure origins and causes and impacts.
162
The effects of climategate caused what % of respondants to say they were less convinced of the risks of climate change?
11%
163
What issues were there in 2009/2010 that damaged peoples perceptions of climate change?
Temperature anomaly, not new climate treaty in Copenhagen summit, financial crash.
164
How did the snow and rain in 2010 have more effect than climategate at changing preception of climate change?
Because personal experience has more of an effect.
165
Surveys are useful but weaknesses are?
They lack detail and meaning, better to speak to people.
166
Is climate change also a humanitarian and social justice issue?
Yes.
167
What is a false balance?
Many countries had two people with opposing views presenting their case, this allows false representation of science.
168
Climate change is seen as invisible and distant to most, this makes it hard to what?
Care about, and campaign about.
169
Two UK government campaigns are?
Helping the Earth begins at home - launched 1991. Explains how families can use energy more wisely, multimedia aimed at children, low success rate and lack of appeal. Act on CO2 - launched 2007. Aims to make climate change more clear and have consistanty from the government and media, also aimed at businesses, had nursery ryhme adverts banned for overstating risks, no clear aim.
170
How does the media represent climate change?
Language and images are important. Science can be translated and shape peoples understanding. Newspapers use fear to sell papers, this can inspire feelings of paralysis. Influencers, trusted names greatly effect peoples opinions.
171
How does science fiction represent climate change?
Examples, the day after tomorrow and cowspiracy, the dramatic context conveys the scientific message. More science AND fiction. The day after tomorrow changed peoples concerns about climate change, same with documentary 'age of stuoid'
172
Climate visuals are for communicating climate change, what are they?
Being honest about the impacts and risks without provoking fear, honest about adaptation and mitigation, emotional responses, consistent language.
173
What is adaptation?
Living with climate change by altering practices.
174
What is mitigation?
Trying to prevent or limit additional climate change by altering practices.
175
Bjorn Lomborg wrote what book making what point?
The skeptical Environmentalist book, says money can be better spent on developing poorer parts of the world.
176
IPCCs 6 reasons for adapting to climate change are?
``` It can not be avoided, less costly than last minute fixes, it may be more rapid than we expect, immediate benefits from extreme events, it can bring opportunities as well as threats. ```
177
Issues with working out carbon footprint are?
Do they mean carbon or carbon dioxide, there's often confusion, where does the change of responsibility start, upstream at production? How is CO2 measured, and what about other GHGs.
178
What is carbon dioxide?
A chemical compound composed of two oxygen covalently bonded to a single carbon atom. A trace gas comprising of 0.04% of the atmosphere.
179
What is CO2e?
CO2 equivalent.
180
Early criticisms of carbon footprinting are?
Many companies hid their carbon footprints and its relevance was questioned.
181
What is the carbon trust?
A not for profit company providing support to businesses boost their returns by cutting carbon emissions and saving energy.
182
Other kinds of footprinting are?
Water, land and social foot printing.
183
What is carbon offsetting?
Compensating for GHG emissions, investing in projects elsewhere that are absorbing or preventing the release of CO2. Can be undertaken by individuals, companies or governments.
184
Drawbacks of carbon offsetting are?
It is complex. Lack of regulation, would the project have happened regardless. Lack of consistency in calculating carbon emissions, and how much should be payed. Uncertainties in how long the offsetting takes to work, may take 100 for trees to remove the carbon, the trees will eventually decay. Also distracts from transition to using less carbon.
185
Two main types of carbon offsetting are?
Official - Mandatory market, the largest, generate credits for carbon caps. Unofficial - voluntary market, smaller, companies and individuals seek to offset their carbon emissions.
186
Future forests, now rebranded as the carbon neutral company is what?
It had lots of celebrity endorsements, e.g, rolling stones wanted people to pay to offset their UK tour. More than 2000 fans payed to offset carbon and not one additional tree was planted, the money was used to refurbish a path in the forest.
187
Examples of some offsetting methods are?
Forest planting, investing in renewable energy, capturing methane release from landfills.
188
Offsetting scheme examples are?
ClimateCore, Carbon Footprint, Carbon Positive.
189
At present, global anthropogenic emissions are what for C and for CO2?
7 Gt/yr C | 26 Gt/yr CO2
190
Food miles have increased by what % in the last 20 years?
50%
191
Transatlantic flight = what % of the average persons CO2 for the whole year?
Almost 50%
192
Does breathing negatively effect CO2 levels?
The carbon came from plants that we ate, which absorbed this from the atmosphere.

208
What are socolow wedges?
The same or similar to stabilization wedges, 8 of them needed 15 options.
209
Carbon mitigation initiative options are?
Improving power efficiency, switching fuel, scale up bio-fuels, natural sinks (plant or preserve trees the size on USA) or use conservation tillage on all cropland.
210
Why is agriculture a huge challenge?
2-3 billion more people by 2050, demand for meat and dairy grow. To change this, is to change an economic system.
211
What % of the habitable earth is used for agriculture? How is this split from humans to animals?
50% is agriculture, 23% of this is to feed humans directly. 77% of this is used for livestock.
212
If everyone had the diet of an average American how much would be needed for agriculture?
138% of the earths habitable land.
213
If everyone had the diet of an average Indian how much would be needed for agriculture?
22% of the earths habitable land.
214
Solutions to food security are?
Increase land used (would mean cutting down forests), improve productivity (negative costs and environmental issues), changing diets, develop new sources of calories, vertical farming.
215
Agriculture, forestry and land use accounted for what % of GHG emissions in 2014.
24%.
216
How can GHGs be managed from agriculture?
Different land management, less food waste, sequestration and nutrient management.
217
What is sequestration?
Soil health and afforestation. Soils store twice the amount of carbon than the atmosphere does. Looking after these soils can mitigate climate change.
218
Climate change damages food production in what way?
Shorter growing seasons, extreme weather effecting maize, soy, wheat and rice most.
219
Climate resilient agriculture is good because?
Improves food security, adaptability, increases productivity.
220
Going vegan reduces GHGs by what %, and how does it reduce landuse?
43% GHG reduction, 70% less land use.
221
In 2016 what % of the worlds population lived in urban areas? What is it estimated to be in 2050?
54.5% in 2016, 66% 2050.
222
What is a mega city?
10 million people or more.
223
What % of the worlds resources are consumed by cities?
70%.
224
How are cities vulnerable to climate change?
Many near water, drainage systems can't cope with increased rainfall, electricity infrastructure vulnerable, bridges and railroads at risk, water and food security.
225
How can cities solve climate issues?
They are highly adaptable, planned well, good engineering, dense living makes it more efficient, a hub for the rest of the country.
226
What is Masdar?
A planned city, started in 2006, aims to be worlds first zero carbon city, first occupied in 2010, powered by solar energy, electric vehicles and high density.
227
Structural factors that effect people choices are?
If there's not railway somewhere you'll have to fly, or you don't have money to be green.
228
Socio-cultural factors that effect peoples choices are?
customs, beliefs, behaviors learn from society.
229
Biological factors that effect peoples choices are?
The brain is a filter and prioritizes immediate needs.
230
What % is food and drink in the average persons carbon footprint in the UK?
25%.
231
Value-action gap is?
People are learning action should be taken but things like fast fashion grow by 5% a year.
232
How did recycling rates improve?
Introduction of landfill tax forced local councils to make structural changes.
233
Dual-system theory is?
Kahneman 2001 - Fast think which is unconscious and slow thinking which is conscious. Behavior is a combination of the two often. They come from different parts of the brain.
234
How does the dual-system theory apply to climate change?
People when asked about their thoughts on taking action use their slow brain, but when actually taking actions throughout the day it is fast thinking.
235
What are the two major models used to try and change peoples behaviors?
Models that try to change cognition's (such as belief and attitudes) Models that change the context/environment where the person acts and make decisions.
236
What is choice architecture?
Physical and social environments where decision making is frame. A nudge. It is aimed at changing peoples behaviors and not educating.
237
Examples of choice architecture are?
Reducing choices, reduce and target information, order of presentation of choice (like vegetarian first), change the default, change the way something is measured e.g. comparing you to your neighbor. Used in advertising, branding something as popular to boost sales, up-selling.
238

Phase 2: 2008-2012, centralized allocations, 60% of allocations auctions, less allowances, aviation brought into it.
240
EU ETS phase 3 is?
Phase 3: 2013-2020, EU wide cap on emissions to be reduced by 1.74% each year, more auctioning, fines introduced.
241
EU ETS is now doing what? When will phase 4 be?
Now: Australia's system linked to it, 20% reduction in emissions expected. Phase 4 will be 2021-2028. Good because it bring certainty on emissions, but the prices fluctuate, potential for too much allocation, the cap is not hard to change.
