Answer 10

A severe reduction in quality of soils, including soil erosion, salinization, and soil exhaustion.

Answer 11

Radiative forcings caused by changes in incoming solar radiation.

Answer 12

Agricultural systems emphasizing biological relationships and natural processes, which maintain soil fertility.

Answer 13

Climate-Resistant Crops – Scientists and farmers are developing flood-, drought-, and salt-tolerant rice varieties, such as "BRRI Dhan 67," which survives underwater for longer periods. Improved Farming Techniques – Farmers are using raised-bed farming and floating gardens to cope with unpredictable weather. NGO Support – Organizations like BRAC and the International Rice Research Institute (IRRI) provide training, seeds, and technology to help farmers adapt. Early Warning Systems – Weather forecasts, and mobile alerts help farmers prepare for floods and cyclones. Diversification – Encouraging fish farming and livestock alongside crops reduces the risk of food shortages.

Answer 14

Cyclone Shelters – Thousands of strong shelters have been built along the coast. NGOs like BRAC ensure they are accessible to women, children, and people with disabilities. Some shelters now have separate spaces for women’s privacy and safety. Early Warning Systems – The government, with help from groups like the World Meteorological Organization, sends cyclone alerts via loudspeakers, mobile phones, and radios. Community Volunteers – The Cyclone Preparedness Programme (CPP), supported by the Red Crescent, trains thousands of volunteers to warn and evacuate people before a storm. Stronger Homes and Infrastructure – NGOs and aid agencies help build storm-resistant homes. Roads and embankments are improved to prevent flooding in villages.

Answer 15

Goalbari is an agricultural village which have a local women’s cooperative has successfully created strategies to adapt to the floods: - Houses were raised 1.2 m above the floodwaters - Floating beds of hyacinths are used as a base on which to grow vegetables as the beds rise and fall with the floodwaters. Avoiding damage from floods

Answer 16

- Bangladesh suffered economic losses worth $3.72 billion and witnessed 185 extreme weather events due to climate change - 90 million Bangladeshis (56 percent of the population) live in “high climate exposure areas,”, with a high population density, ranked 12 leading to people living in flood prone areas with 1 million deaths in the last 200 years. - 2/3 are 4.5m above sea level and 1/3 by the coast of Bangladesh

Answer 17

- By 2050, one in every seven people in Bangladesh will be displaced by climate change. Bangladesh may lose approximately 11% of its land by then, and up to 18 million people may have to migrate because of sea-level rise alone. - When the flood water subsided, fields were too salty for shrimp, village buildings were flattened and there was no fresh water to drink. - In 2020, Cyclone Amphan took the lives of 10 people in Bangladesh (and 70 others in India), left thousands homeless, and destroyed at least 176,007 hectares of agricultural land in 17 coastal districts. It was the strongest cyclone ever recorded in the country’s history.

Answer 18

Closely related due to high primary sector employment such as farming and fishing near river/ coasts which are affected by floods and storms, plus due to the fact that it is commonly subsistence farming when crops are destroyed so does food Women and disadvantaged groups are suffering more during disasters as they don’t receive warning in time and women have to take care of their children, elderly and disabled.

Answer 19

- In the pre-disaster stage of a flood, residents can try to prepare by increasing their savings, raising their house on stilts and moving important items to safer places. In the post-disaster period, it will sell assets to buy food and equipment. - Developed its flood action plan: sluice gates built on rivers, built 5700km of embankments, dug 5000km draining channels to divert water from building. - 200 flood shelters, residents can prepare by saving or raising house on stilts

Answer 20

Food insecurity. due to storms and salination of soil Water scarcity: reduced rainfall, longer droughts and contamination of water with sea Land degradation: River bank/ coastal erosion and sea level rise consuming 10.9% of Bangladesh. Greater loss of livelihoods and displacement rely on infrastructure

Answer 21

- Changing weather patterns will result in: Drought and heatwaves in the south-east of England will become more common Flooding in the north-west will become more common (due to an increase in winter precipitation) - The total rise in sea levels off the coasts of the UK may exceed 1 metre and a rise of 2 metres cannot be excluded. - The frequency of storm events is expected to increase in combination with the rise in sea level, is expected to lead to an increase in flooding. - Land is sinking in the south and east of England (due to the sheer weight of urban areas), whereas in the north land is rising (due to the slow rebound of the land following the last ice age). Therefore, the risk posed by rising sea levels will be more severe in the east due to these localized isostatic changes.

Answer 22

- By 2050 more than 180,000 homes will be at risk of flooding - The cost of flooding in the UK is currently estimated at £340 million per year, this is predicted to rise to £430 million if temperatures rise by 2 degrees. - There will be a northward shift in farming zones which will improve pastoral farming in the northwest. Timber yields may also increase in the northwest but decrease in the south There may also be further expansion of viticulture (wine growing) in England. - Higher temperatures and reduced precipitation in the summer, especially in the south of England, could lead to enhanced potential for tourism.

Answer 23

- In the UK, people’s lives are not closely linked to the extreme environment as many more people work in tertiary jobs rather than in the primary sector e.g. farming and fishing which may be more affected by rising sea levels and changing temperatures. - However, there are many densely populated areas of the east coast that are at risk from coastal flooding e.g. Kent, Essex and London.

Answer 24

- The UK is a high-income country meaning that people are less vulnerable as they have resources to help them if they suffer from the impacts of climate change e.g., flood insurance, savings, credit cards. - However, there are many disadvantaged coastal communities, at risk of the physical impacts of climate change and which already suffer from high levels of deprivation or geographic isolation. - The UK has an ageing population and almost all the local authorities with the largest percentage of over-65s are located on the coast. Older people may be more vulnerable to climate change as their bodies may be too frail to cope with increased heat waves.

Answer 25

- The UK has a high capacity to cope as they have an awareness of the risks posed and have the resources to address the potential impacts. - There are already management strategies in place to protect settlements e.g., coastal defenses and the Thames Barrier, which protects London from coastal surges. - There are also plans to upgrade coastal defenses as needed (although this will be very expensive).

Answer 26

- According to the CCVI the UK has low vulnerability to climate change as they have a score of 9.96/10 - The UK has low overall vulnerability as they have a resilient population and a high capacity to cope with the changes brought about by climate change. - However, the impacts of climate change will not be uniform for the UK and its ageing population and disadvantaged coastal communities will present challenges. Another challenge will be the huge costs that will be associated with upgrading the UK’s coastal defenses.

Answer 27

To limit the temperature increase to 1.5 celsius above pre-industrial levels Climate change agreements and finance - help developing countries Global peaking and 'climate neutrality' (Art. 4) Parties aim for global peaking of greenhouse gas emissions, recognizing longer peaking for developing countries, to balance emissions and removals in the second half of the century. Mitigation (Art. 4) - The Paris Agreement mandates all Parties to prepare, communicate, and maintain a nationally determined contribution (NDC) and pursue domestic measures. Parties must communicate their NDCs every 5 years, with each successive NDC representing the highest possible ambition. Developed countries lead by setting absolute reduction targets. Sinks and reservoirs (Art.5) - The Paris Agreement also encourages Parties to conserve and enhance, as appropriate, sinks and reservoirs of GHGs as referred to in Article 4, paragraph 1(d) of the Convention, including forests. Voluntary cooperation/Market- and non-market-based approaches (Art. 6) - The Paris Agreement requires all Parties to set a nationally determined contribution (NDC) and implement domestic measures, with developed countries setting absolute reduction targets every 5 years. Adaptation (Art. 7) - The Paris Agreement aims to enhance adaptive capacity, strengthen resilience, and reduce climate change vulnerability globally. It encourages national adaptation efforts through international cooperation and acknowledges the global challenge of adaptation. Parties should develop National Adaptation Plans. Loss and damage (Art. 8) - The Paris Agreement emphasizes preventing and minimizing climate change-related loss and damage, emphasizing sustainable development's role in reducing such risks. Parties are encouraged to cooperate and support this through the Warsaw International Mechanism. Finance, technology and capacity-building support (Art. 9, 10 and 11) - The Paris Agreement emphasizes the responsibility of developed countries to support developing countries in building clean, climate-resilient futures, encouraging voluntary contributions and balancing adaptation and mitigation. It strengthens international cooperation on technology development, capacity-building, and climate change education. Climate change education, training, public awareness, public participation and public access to information (Art 12) Transparency (Art. 13) The Paris Agreement promotes transparency, implementation, and compliance through a robust accounting system, international technical expert review, and a mechanism for non-adversarial compliance. It requires annual reporting to the CMA and ensures flexibility for Parties' capabilities. Global Stocktake (Art. 14) A global stocktake in 2023 and every 5 years will assess progress towards the Agreement's long-term goal, enhancing actions and international cooperation on climate action based on available science. Decision 1/CP.21 aims to improve action before 2020 by strengthening technical examination processes, providing urgent finance, technology, and support, and fostering high-level engagement. It also encourages non-Party stakeholders to scale up efforts and recognizes the importance of strengthening local communities and indigenous peoples' knowledge, technologies, practices, and incentives through domestic policies and carbon pricing.

Answer 28

195 members signed the treaty and around 132 of them ratified it (sign or give formal consent to (a treaty, contract, or agreement), making it officially valid.) As of 2025, all 197 UN countries have endorsed the Paris Agreement, with 195 formally approving it. The only countries that have yet to formally join the agreement are Iran, Libya, and Yemen.

Answer 29

Successes - Global participation (all but 4 countries are involved in the agreement: the USA, Yemen, Iran and Libya) - Growth of renewable energy, more countries are investing in renewable energy sources and reducing their reliance on fossil fuels - Net zero emission pledges - Climate finance commitment- developed nations pledged to provide 100 billion USD a year to developing countries in order to support them in climate action Failures - Weak enforcement, it relies on voluntary commitments and has no legal consequences for those who don’t join - Trump’s withdrawal from the agreement during both his terms - Emissions still haven’t been cut as much, with the world still on track for rising temperatures of 2.5-3 degrees C - Developed nations have failed to meet their pledge of donating 100 billion per year - Countries such as China and India are still dependent on fossil fuels for their energy.

Answer 30

Adaptation and Mitigation Climate change conferences are annual conferences that allow countries to come together to discuss climate change issues and create legislation to manage climate change. Pros: - In 2015 195 countries signed the Paris Agreement - it is the first climate change treaty to apply to all countries. This gives us hope for the future that all countries are committed to avoiding dangerous climate change. - Some important agreements were made at COP29 in 2024, that saw wealthy nations pledge $300 billion in climate finance for developing countries Cons: - It has been said that the pledges made through NDCs are not challenging enough. For example, based on the promises made by individual countries we are on track for 2.4 degrees temperature rise - this is catastrophic climate change and means the Paris Agreement is currently on track to fail. - $300 billion in climate finance was pledged at COP29, however, this fell short of the trillion dollar figure demanded by developing countries.

Answer 31

Mitigation Carbon offset: Activities or projects that aim to reduce or offset carbon emissions by funding activities/projects that reduce emissions elsewhere e.g. investing in tree planting or renewable energy projects. Pros: Reduces Overall Emissions Supports Green Initiatives Easy for Individuals & Businesses Cons: Not a True Solution Difficult to Measure Impact Potential for Greenwashing Long-Term Effectiveness Varies Carbon trading: Attempts to create a market in which emission permits issued by governments can be traded. Companies that exceed their targets have to buy emission permits from those who do not - this market system helps to limit emissions. Pros: Encourages Emission Reductions Promotes Green Innovation Flexible for Companies Funds Climate Projects Cons: Can Be Exploited Unequal Impact Difficult to Regulate May Delay Real Change

Answer 32

Mitigation Geoengineering artificially manipulates Earth's environmental systems to reduce climate change effects, while not addressing its causes, but could aid in combating greenhouse gas emissions. E.g Carbon captures, aerosols, space mirrors. Carbon capture and storage Pros: Reduces CO₂ Emissions Works with Existing Industries Helps Fight Climate Change Can Be Used for Other Purpose Cons: Expensive Not 100% Effective Energy-Intensive Storage Risks Doesn’t Solve the Root Problem Aerosols Pros: Reduces amount of solar radiation that comes to earth Shows to work by mother nature Just enough to change global temperatures Space mirrors Pros: Reduces Global Warming No Impact on Daily Life Buys time Cons: Expensive Difficult to Build Unpredictable Effects Doesn’t Fix Root Cause

Answer 33

Mitigation - Replacing fossil fuels with reneable energy - Reduce nitrogen-containing fertilizers in agriculture and livestock by changing feedstock and selective breeding to minimize methane emissions. - The government is promoting energy conservation through education, investment in electric car charging stations, congestion charges, and tolls in cities like Stockholm. Pros: - Reduces greenhouse gas emissions - Job creation - more employees will be needed for the renewable energy sector - Addresses the issue at the source and prevents future growth of emissions, unlike adaptation strategies Cons: - Governments have lots of restrictions and decision making can be a long process, so they can’t respond to changes and make fast decisions - Renewable energy and electric cars are in early stages of implementation and development, so they are more expensive and less likely to be used. Because of this, developing countries will be less likely to adopt these things.

Answer 34

Adaptation The Netherlands has implemented flood management strategies, such as building dikes, dams, and floodgates, to prevent flooding from rising sea levels. The Afsluitdijk, built between 1920-1925, withheld a 1953 flood, and governments enforce sustainable practices through laws and regulations. Pros: Flood management strategies can be effective, especially when hard engineering strategies are used. This gives the public confidence and protects them from economic losses. Cons: - Expensive leading to inadequate funds and finance. This also means all countries aren’t able to implement these sorts of projects. - Information and knowledge gaps in developing countries hinder effective planning and investment decisions.

Answer 35

The energy balance is the balance between incoming energy from the sun and outgoing energy from the atmosphere. Energy released from the sun is in the form of shortwave light and ultraviolet energy. The earth releases long wave infrared energy. The functioning of the atmospheric system: - The atmosphere is an open system, receiving radiation from both the sun and the earth itself. - The energy of the earth is very small, but it does have an effect. - Incoming solar radiation is referred to as insolation. - The main energy that drives all of our weather systems and our climate comes from the sun. - The vast majority of this energy is absorbed at the equator whereas energy is generally lost in the polar regions. - However, this energy is redistributed to higher latitudes by wind and air circulations.

Answer 36

Sunspots are dark spots on the sun’s surface. Times of maximum sunspot activity are associated with a very slight increase in the energy output from the sun. Ultraviolet radiation increases dramatically during high sunspot activity, which can have a large effect on the Earth's atmosphere.

Answer 37

Explosive volcanic eruptions have been shown to have a short-term cooling effect on the atmosphere if they eject large quantities of Sulphur Dioxide into the stratosphere. This can have an effect on climate because of ash and SO2 reducing the reception of solar radiation on the Earth's surface. This is referred to as global dimming.

Answer 38

Over time these three cyclic events vary the amount of solar radiation that is received on the Earth's surface. The cycles involved are eccentricity/elliptical (100,000 years), obliquity (41,000 years), and precession (26,000 years).

Answer 39

- Dimming is caused by an increase in particulates and sulfate aerosols, which reflect sunlight back out to space. - The particles also change the characteristics of clouds as they act as seeds for water droplets. Water coalesces around the particles and form larger droplets with a higher albedo, which reflect more solar radiation back to space. - The source of such particles may be natural (e.g. volcanic eruptions) or anthropogenic (caused by humans), generally through the combustion of fossil fuels (coal and oil) and wood. - Major volcanic eruptions generally produce carbon dioxide (a greenhouse gas, GHG), ash particles and sulfur-rich gases. Such eruptions can have a significant impact on incoming solar radiation (among other things).

Answer 40

- Waterlogged conditions in the world’s wetlands and rice fields encourage anaerobic decomposition of organic matter, which releases methane. - Methane is a byproduct of the digestive processes of herbivores such as cows, sheep and termites. It is also a minor byproduct of our own digestive processes. - The oceans produce methane through microbial activity and mud volcanoes on the seafloor. - Fossil fuel production, distribution and use are the largest anthropogenic contributors of methane to the atmosphere. The extraction and combustion of all fossil fuels releases methane into the atmosphere. - Landfill and waste disposal sites are sources of methane through the decomposition of organic matter in solid domestic waste. - Burning biomass and using biofuels releases methane. This can be through burning off crop waste, land clearance, forest fires, cooking and heating, among other things.

Answer 41

- There has been an increase in the amount of fossil fuels being burned. - Changing diet has meant an increase in the amount of meat and rice that is consumed globally. This has increased the number of herbivores (cows and sheep) that are kept and the number of rice paddies, both of which produce large amounts of methane. - A steadily increasing population is generating ever-increasing amounts of waste, the decomposition of which generates methane. - Rising temperatures increase methane emissions from fresh water. - Rising temperatures are also exposing permafrost, which is thawing and releasing additional methane.

Answer 42

The two major causes of global sea level rise are thermal expansion caused by warming of the ocean (since water expands as it warms) and increased melting of land-based ice, such as glaciers and ice sheets.

Answer 43

Poorer people Less able to afford rising food prices Forced to live in marginal areas due to cheaper housing More susceptible to diseases Women Less likely to have received education over men in developing countries. This means they get less access to information and services that might help them understand and cope with the impact of climate change. Traditional clothing impedes the ability to run or swim if they have to escape a climate change caused disaster. May not be able to migrate because in some societies they must require permission from male relatives. Old people Less actively involved in the workforce meaning they lack financial resources needed to adapt to for example rising food prices. At risk to the spread of vector-borne diseases like malaria which are expanding due to climate change. Children At risk to the spread of vector-borne diseases like malaria which are expanding due to climate change.

Answer 44

Heat waves - increased heat causes cardiovascular and respiratory problems - elderly people are vulnerable - can cause heat syncope (fainting) Extreme weather events such as storms and floods can cause injuries or deaths. Anthrax outbreaks - As permafrost melts anthrax spores are released which causes rare diseases in animals. Over 2,300 reindeer have died in northern russia, and humans are contracting the same disease.

Answer 45

Water and food security - Climate change can affect access to clean water and food supplies due to drought or flooding. This leads to malnutrition and dehydration

Answer 46

Increased burden on health systems - climate change leads to extreme weather events and a rise in illness linked to these changes, healthcare systems can become overwhelmed, making it harder to provide care to those in need Air quality - air pollution worsens due to climate change; which leads to respiratory issues (asthma & lung diseases)

Answer 47

Act to reduce the severity or intensity of climate change by reducing the output of greenhouse gases and/or increasing greenhouse stores

Answer 48

Adjust to changes in the environment, for example by building coastal defences, rather than trying to stop climate change from happening

Answer 49

Society considered as a community of citizens linked by common interests and collective activity. Civil society is the “third sector” of society, along with government and business. It comprises civil society organizations and non-governmental organizations.

Answer 50

Raising awareness: such as by simplifying climate research and communicating it to the general public e.g. 350.org. Advocacy: an individual or group that aims to influence decision making e.g. through petitions. Lobbying: explicit attempts by activists to persuade politicians, journalists or development organisations e.g. the World Bank etc toward a particular viewpoint. Campaigns: If awareness raising and advocacy continues for a period of time it can be considered a campaign. Civil Society groups that engage in campaigns relating to climate change include Greenpeace, WWF, 350.org etc Protests and demonstrations: Protests may be related to a single climate change issue, such as the Keystone XL Pipeline, or they may be more general in nature, such as street protests by organised groups. Corporate boycotts: To boycott means to refuse to have dealings with (a person, a store, an organization, etc.) usually to express disapproval or to force acceptance of certain conditions. Such strategies are used by civil society to place pressure on companies that are acting unethically or are fueling climate change. Direct action: The work done by NGOs or other civil societies for people who do not have the financial means to do it themselves e.g. water wells provided to villages in the Sahel by charities to counter the impacts of droughts.
