Q

the history of the global warming debate - 1957

A
  • this view changed dramatically = Hans Suess and Roger Revelle
  • discovered a complex chemical process which limited the capacity of oceans to absorb CO2
  • this mean that the residence time of CO2 in the atmosphere was much longer than previously thought

Q

what 5 pieces of evidence are in favour of the idea of humans warming our climate (warmists)?

A
  1. the 2010 Anderegg study found that 98% of climate researchers publishing most actively in their field agree that human activity is primarily responsible for global climate change
  2. dramatic changes in precipitation, such as heavier storms and less snow, are another sign that humans are causing climate change
  3. rising levels of human produced gases released into the atmosphere create a greenhouse effect that traps heat and causes global warming
  4. avg temperatures on earth have increased at a rate far faster than can be explained by the models of natural climatic factors alone
  5. about a quarter of the globe’s glacial loss from 1851-2010, and approximately 2/3 of glacial loss between 1991-2010 is attributable directl yto global warming caused by human-produced GHGs.

Q

what 5 pieces of evidence are against the idea of humans warming our climate?

A
  1. in 2010 Cliamte Depot released a report featuring more than 1000 scientists, several of them former UN IPCC scientists, who disagreed that humans are primarily responsible for global climate change. changes in solar and volcanic activity are often cited as being contributors
  2. earth’s climate has always warmed and cooled, and the 20th century rise in global temperature is w/in the bounds of natural temp fluctuations over the past 3000 yrs
  3. CO2 is already saturated in earth’s atmosphere, and more CO2, manamde or natural, will have little impact on climate
  4. the IPCC predicted that Himalayan glaciers would likely melt away by 2035, a prediction they disavowed in 2010. in 2014 a study of 2181 himalayan glaciers from 2000-2011 showed that 86.6% of the glaciers were not receeding
  5. increased hurrican activity and other extreme weather events are a result of natural weather patterns, not human caused climate change.

Q

what did the Kyoto protocol involve?

A
  • during Kyoto protocol legally binding targets were set for 37 industrialised countries and the EU member states to reduce emissions of GHG by an average of 5% below their 1990 levels by 2012
  • this first phase entered into force (after much discussion) in 2005
  • during a second commitment period (2013-2020), parties committed to reduce GHG emissions by at least 18% below 1990 levels in the 8yr period
  • however the composition of parties in the second committment period is different from the first, with Canada, Japan and Russia pulling out

Q

what was actually agreed at COP26 - kyoto protocol

A
  • the legally binding protocol demands an avgd 5% cut in GHG emissions from the industrialised world as a whole by 2012
  • each country has been set its own individual targets based on its pollution levels
  • growing/developing countries are outside the framework
  • even for countries that agreed to sign up, meeting the goals could be difficult
  • canada has no clear plan for reaching targets (its emissions have increased by 20% since 1990)

Q

why was it so crucial for Russia to join the Kyoto protocol?

A
  • russia ratified the treaty in 2004
  • its entry was vital because the protocol had to be ratified by countries accounting for at least 55% of global GHG emissions to be valid.
  • the target was only met after russia joined
28
Q

how is the EU a part of the climate change debate?

A
  • the EU is leading the way in tackling climate change and has put together a comprehensive package of measures to reduce GHG emissions
  • the most well known/successful is the Emissions Trading System (ETS)
29
Q

what is the ETS?

A
  • the Emissions Trading System (ETS) is a cap and trade scheme limiting emissions from 11,000 high polluting industries across 27 EU countries
  • which works by giving incentives for a reduction in carbon emissions and penalising heavy polluting industries and sectors
  • it covers 45% of total EU emissions including power stations and industries such as steel works
  • it is targeting a 21% reduction in emissions
  • member states also have targets for expanding the contribution of reneweables to national energy production and for improvements in energy efficiency
30
Q

what do National Emissions Reduction targets cover?

A
  • National Emissions Reduction targets cover the remaining 55% of GHG emissions after the ETS, mainly from agriculture, housing, waste and transport
31
Q

what are the 4 aspects of the UK govt climate change strategy?

A
  • set carbon budgets
  • low carbon technologies
  • carbon taxes
  • reduced demand for energy
32
Q

how are SETTING CARBON BUDGETS a part of the UK climate change strategy?

A
  • five year periods
  • as stepping stones towards the 2050 target
  • for ex, the reduction targets for the period 2013-2017 and 2018-22 are 29% and 35% respectively
33
Q

how are LOW CARBON TECHNOLOGIES a part of the UK climate change strategy?

A
  • investing in LCT such as carbon capture and storage
  • and encouraging the growth of renewables (e.g. wind, solar, biomass) by offering subsidies and reducing GHG emissions from power stations
34
Q

how are CARBON TAXES a part of the UK climate change strategy?

A
  • to switch electricity generation from coal to greener fuels
  • in 2014, there were just 10 coal fired power stations in the UK but they were responsible for 1/5 of UK carbon emissions
  • introduced in 2013, taxed carbon emissions started at £16/tonne, with a planned rise to £70/t in 2030
  • in 2015 the tax was frozen at £18/t amind concers about electricity cost to consumers
  • 3 of the UK’s remaining coal fired stations closed 2015/16 due in part to carbon tax and low global energy prices
  • carbon taxes have been levied on vehicle CO2 emissions since 2002
35
Q

how is REDUCING DEMAND FOR ENERGY a part of the UK climate change strategy?

A
  • using domestic smart meters
  • promoting energy efficiency (e.g. insulation in buildings) and decreasing GHG emissions from transport to agriculutre
36
Q

why didn’t india ratify the Kyoto protocol?

A
  • like other EDCs/LIDCs, the indian govt argued that rich countries should shoulder the costs of decreasing carbon emissions
  • they said its per capita energy consumption (1.7tonnes) was well below global avg of 5 tonnes
  • prioritising alleviating poverty and expanding electricity access
  • current high concs. of CO2 in atmosphere were largely the result of economic growth and industrialisation in ACs over last 150yrs
37
Q

how did India not ratifying the Kyoto protocol impact on the success of it?

A
  • this view prevented the USA ( the world’s biggest emitter at the time) from supporting Kyoto
  • the US govt believed that w/o the participation of India and China the Kyoto protocol would be meaningless
38
Q

whilst india will not consider reducing its emissions for at least 30yrs, what are they doing to combat climate change?

A
  • has its own national action plan on climate change (NAPCC)
  • so far its only decided to decrease its GHG emissions as a ration of its GDP
  • using this measure it targets a 20-25% decrease in emissions (based on 2005 levels) by 2020
  • voluntary commitment. will do little to stem the country’s huge absolute rise in GHGs
  • aims to improve energy efficiency and develop renewables, esp solar.
39
Q

by how much are India’s GHG emissions predicted to rise from 2010-2030?

A
  • given its current policies GHG emissions are expected to be in the range 4.0-7.3 bill tonnes by 2030
  • this compares w/ 2.43bill tonnes in 2010
40
Q

how would left leaning newspapers report on climate change?

A
  • e.g. the guardian. political parties Labour/Green Party
  • usually more progressive in nature - look to the future and aim to support those who can’t support themselves
  • agenda to inform public of danger of human activity in regards to climate change
  • cares about society
41
Q

how would right leaning newspapers report on climate change?

A
  • e.g. the Times/Sunday Telegraph. Political parties Conservative/UKIP
  • value tradition and believe in economic freedom
  • right leaning newspapers are more likely to report sceptical opinions of climate change
  • this makes the climate change issue appear more open to question than it really is
42
Q

what is false balance?

A
  • by giving disproportionate coverage to contrarians and sceptics, they suggest that climate change is far more controversial than experts believe
  • instead of balance, climate experts argue that reporting should reflect the huge weight of scientific research in favour of climate change.
  • all of this has tended to confuse the public and add doubt to the credibility of climate change and its causes.
43
Q

who are pressure groups and what do they do?

A
  • groups that seek to influence govt. legislation and policies.
  • they don’t have candidates for elections, nor are they seeking to gain power for themselves; they merely seek to influence those in power
  • they challenge leaders and people to consider the problems they are addressing through protests, interviews, social media etc.
  • often emotive in language, as they are urging people to join
  • they are mainly run off donations, which limits them
  • they can be local, national, international and permanent/temporary
44
Q

what are the agenda’s of pressure groups?

A
  • seek to influence or change government legislation and policies
  • practical achievability, resources, relation to govt and public receptivity are factors in the success of a pressure group
  • utilise lobbying, influencing political parties, endorsement, electioneering to achieve their aims
45
Q

how are pressure groups involved in the climate change debate?

A
  • pressure groups in the climate change debate are environmentalist meaning that they are a person who is concerned about or advocates protecting the environment
  • they want attention to be able to spread their message and in doing so they can challenge media, TNCs and govts.
  • their agenda is about gaining power to push their ideas, they focus on the long-term problems
46
Q

what is an example of a pressure group?

A

GREENPEACE
- one of the more successful pressure groups, they are more peaceful with their demonstrations and challenge perspectives, they are able to gather followers to further aid their cause
JUST STOP OIL
- more extremist, often using irritation techniques to become noticed by media and public figures, they have been ineffective and people are unwilling to back them due to their often illegal but also invasive style of pressure. it seems more about attention
- incredibly vague, scare tactics.

47
Q

what are some examples of Greenpeace’s agendas?

A
  • spearheading a global campaign to make polluting fossil fuel companies pay for the damage they cause
  • championing big climate solutions from home insulation to offshore wind, so the UK becomes a model for climate action globally
  • demanding governments protect 30% of our oceans by 2030 safeguarding wildlife, coastal communities and our climate
48
Q

how are pressure groups usually recieved?

A
  • pressure groups are often not recieved well because of their techniques, grassroots activies causing annoyances in order to get attention for their cause - probably hurts their effectiveness.
49
Q

how do pressure groups shape the argument?

A
  • by influencing people, they are able to present arguments and therefore challenge media, TNCs and govts
  • their power comes with the number of people they have to be able to create petitions, or boycotting which has become a popular technique recently.
  • they present arguments and demands to those in power, so do have in a sense some power BUT it is limited as its reliant on the media, TNC’s and govts listening and following through on promises.
50
Q

what is the significance of pressure groups?

A
  • they have the potential to spark change at every level of the debate
  • however, they are reliant on donations, followers and being listened to in the first place
  • their demands often cause issues for TNCs and govt
  • they often provide demands but not solutions and so its more difficult for change to happen, esp since TNCs and govts are mainly focused on economic health
51
Q

who are governments?

A
  • a government is the system or group of people governing an organized community, generally a state.
  • governments usually consist of legislature, executive and judiciary
52
Q

who makes up the UK govt?

A
  • in the UK, the prime minister leads the govt with the support of the cabinet and ministers
  • 1 prime minister, 23 cabinet ministers, 101 other ministers
  • departments and their agencies are responsible for putting government policy into practice
53
Q

who makes up the US government?

A
  • the president is both the head of state and head of government of the United States of America, and commander-in-chief of the armed forces. The president is responsible for the execution and enforcement of the laws created by congress
  • currently Joe Biden is president
54
Q

what is the difference between the democratic party and the republican party?

A
  • the modern democratic party emphasises social equality and equal opportunity
  • democrats support voting rights and minority rights, including LGBTQ+ rights
  • the republicans advocate reduced taxes as a means of stimulating the economy and advancing individual economic freedom
55
Q

what is the agenda of governments?

A
  • the stance of global climate change will differ between governments/countires
  • for example, the UK stance on reducing global climate change emissions will differ to that of CHina.
  • emergence of the secondary industry in China = driving the economy. China has pulled out of certain climate agreements e.g. Kyoto so they can maximise their industry w/o the need to keep under emission caps
56
Q

what is the climate change act?

A
  • the climate change act of 2008 commits the UK govt BY LAW to reducing GHG emissions by at least 100% of 1990 levels by 2050
  • the UK was the first country in the world to create a legally binding national commitment to cut GHG emissions
  • the act created a climate change committee which is responsible for putting forward carbon emissions budgets to the government
57
Q

how does the UK government shape the debate?

A
  • funding, regulating and directly providing public services
  • committed to reaching net zero by 2050.
  • this means that the total GHG emissions would be equal to the emissions removed from the atmosphere, with the aim of limiting global warming and resultant climate change
58
Q

how does the US government shape the debate?

A
  • after rejoining the Paris agreement, president biden created the national climate task force working on
  • reducing US GHG emissions by 50% below 2005 levels in 2030
  • reaching 100% carbon pollution free electricity by 2035
  • achieving a net-zero emissions economy by 2050
  • delivering 40% of the benefits from federal investments in climate and clean energy to disadvantaged communities
59
Q

evaluation of governments in shaping the climate change debate

A
  • the UK’s climate change act 2008 is legally binding, so its a good example of a country actually doing something
  • trump, OTOH, didnt sign the Paris agreement because he wanted to prioritise america’s economy.
  • SHORT TERMIST
  • goal of re-election. can divide the country based on their political opinions.
60
Q

what are supranational institutions?

A
  • multinational unions
  • where member states share in decision making on matters that will affect each country’s citizens
61
Q

what was the kyoto protocol?

A
  • the main goal was to control emissions of the main human emitted GHGs
  • the protocol was adopted in Kyoto, Japan in 1997, when GHGs rapidly threatened the climate/planet.
  • it was replaced by the paris agreements which came into effect in 2016
  • countires that agreed to Kyoto were assigned max carbon emission levels for specific periods and participated in carbon credit trading.
62
Q

what is the significance of supranational institutions in the climate change debate?

A
  • strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries
  • integrate climate change measures into national policies, strategies and planning
  • improve education and awareness raising.
  • promote mechanisms for raising capacity for effective climate change planning and management in least developed countries and SIDS, including focusing on women, youth and marginalized communities
63
Q

what is media?

A
  • social media
  • newspapers - the guardian, sun, BBC
  • TV news
64
Q

what is the media’s agenda?

A
  • to get people to buy their newspapers
  • different news platforms have different agendas
  • the guardian = left wing, so cares about society and aims to inform public of danger of human activity
  • GB News = right wing - might prioritise economic factors.
65
Q

how significant is media in shaping the debate?

A
  • prime source of info for general public
  • public more inclined to listen to media rather than politicians (esp young gen)
  • influence public opinions, highlights diff perspectives
  • choice of language uses, and emphasis of certain aspects can impact how people percieve and understand climate change issues.
  • social media/short form content oversimplifies the sheer scale of it
