Glossary
- Abiotic: Physical rather than biological - relating to non-living things.
- Active citizenship: Bringing about change through active participation in society, for example, voting, campaigning, or volunteering for a charity.
- Adaptation: Actions taken to help cope with the effects of climate change, for example, building flood defences, or planting new crops that will thrive under new conditions. Not to be confused with the biological definition ie a characteristic of an organism that improves the likelihood of it surviving and/or reproducing.
- ALAN: An acronym for Artificial Lighting At Night.
- Alternative energy: Sources of energy that are produced without burning fossil fuels, such as solar and wind power.
- Anthropocene: An unofficial term for the current geological age; the period during which human activity started to have a notable impact on the climate and environment.
- Anthropogenic: Man-made climate change, as opposed to natural climate changes caused by things like climate change sunspots, tectonic events, or changes in Earth’s orbit around the sun.
- Atmosphere: The complex layer/s of gases that envelop the Earth.
- Biodiversity: The variety of living organisms, such as animals and plants, in an ecosystem. Ecosystems are dependent on biodiversity to persist and to work properly, and we are dependent on ecosystems to function.
- Biofuel: Fuel derived directly from biological sources, for example plants and some types of waste.
- Biomass: A collective term for organic matter derived from plants, animals, and microorganisms
- Biotic: Biological rather than physical - relating to living things.
- Campaigning: Actions or events organised by an individual or a group to achieve a specific aim.
- Carbon budget: The cumulative amount of greenhouse gas emissions permitted over a set period to keep within an agreed temperature threshold. Carbon budgets can be agreed on different scales: individually, on an organisational scale, nationally, and globally.
- Carbon capture and storage: A process that prevents carbon dioxide (CO2) from entering the atmosphere when it is emitted from sources such as coal-fired power plants. It is used in areas where reducing emissions is particularly difficult, for example in some types of heavy industry. CO2 is compressed, transported, and then injected underground into deep geological reservoirs.
- Carbon dioxide (CO2): A gas in the Earth’s atmosphere. CO2 comes from both natural sources (including volcanoes, the breath of animals and plant decay) and human sources (primarily the burning of fossil fuels like coal, oil, and natural gas to generate energy).
- Carbon dioxide equivalent (CO2-eq): A measure used to compare emissions from greenhouse gases according to their global warming potential (GWP). This is done by converting amounts of other gases to the equivalent amount of carbon dioxide with the same global warming potential.
- Carbon footprint: The amount of carbon released into the atmosphere by a group or an individual, as a result of everyday activities or the manufacture of a specific product. Carbon emissions – in the form of carbon dioxide and methane - are what cause global warming and climate change. Carbon footprints do not only apply to people - they can be calculated for companies, events, places, and products.
- Carbon-neutral: A person, company or country that balances the carbon dioxide they release into the atmosphere through their everyday activities with the amount they absorb or remove from the atmosphere. This is also called net zero carbon emissions or net zero carbon, because overall no carbon dioxide is added to the atmosphere.
- Carbon offsetting: A way to compensate for greenhouse gas emissions, by funding or playing a part in attempts to remove CO2 from the atmosphere. Sometimes this can mean investing in global environmental projects, such as land restoration or tree planting.
- Carbon sinks: Any mechanism that removes CO2 from the atmosphere. The major natural carbon sinks are plants, oceans, and soil.
- Carbon sources: Any mechanism that releases more CO2 into the atmosphere than it absorbs, for example,
- burning fossil fuels or volcanic eruptions.
- CFCs: The short name for chlorofluorocarbons – a group of greenhouse gases that are harmful to the ozone layer.
- Climate: The average weather patterns over a long-term period (over 30 years at least).
- Climate change: The most commonly used term to describe long-term change in global or regional climate patterns, as a result of increasing levels of CO2 and other greenhouse gases in the atmosphere.
- Climate finance: Funding on a local, national, or international level that is invested in climate change related activities, to support adaptation.
- Climate justice: A concept that acknowledges the inequitable outcomes of the climate crisis - that climate change will not affect everyone in the same way, and that this will lead to inequalities between places, people and even generations.
- Climate refugee: Someone who has been forced to leave their home as a consequence of the climate crisis and sudden or long-term changes to their environment.
- Citizen science/Community science: Scientific work undertaken by members of the general public, often in collaboration with or under the direction of professional scientists and scientific institutions.
- COP26: COP is an abbreviation of Conference of the Parties. COP meetings happen annually and provide an organised environment for international governments, organisations, and individuals to gather and discuss how best to tackle climate change together. The 26th UN Climate Change Conference took place in Glasgow in November 2021.
- Deforestation: The removal of trees to clear an area of forest to make space for growing crops, animal grazing, construction, manufacturing, or to procure timber. This can lead to significant carbon dioxide emissions.

- Emissions: An amount of material produced and released into the air, that causes harm to the environment; in particular, carbon dioxide and other greenhouse gases.
- Enhanced greenhouse: The increased concentration of greenhouse gases, thought to be the cause of recent effect global warming.
- Energy conservation: An effort to reduce energy consumption, by using energy more efficiently or using less energy altogether.

- Fast fashion: A collection of design, manufacturing and marketing methods that aim to produce fashionable clothes as quickly and as cheaply as possible. These clothes often sample designs from the catwalk or celebrity culture and are, in many cases, only worn a handful of times before being thrown out.
- Finite resources: Non-renewable resources that cannot be replaced and will one day run out.
- Fossil fuels: Natural fuels, such as natural gas, coal, and oil, formed in the geological past from the remains of living organisms. Most greenhouse gases are produced when fossil fuels are burnt for energy. They are a finite resource.

- Interest group: An organisation formed to try and persuade the government to adopt specific policies on a particular issue.
- Light pollution: Light which escapes from artificial lights (See ALAN). Often referred to as ‘unseen pollution,’ it can cause harm to wildlife and humans by changing sleep and feeding patterns. It can also create exposure to predators and affect avoidance behaviour and animals’ ability to breed.
- Lobbying: A group or individual trying to persuade a politician to take up their cause - for instance, by starting a petition, writing a letter, or organising a demonstration.
- Methane: A powerful greenhouse gas produced both naturally and through human activity. Whilst methane does not stay in the atmosphere for as long as carbon dioxide, it has a greater heat trapping ability making it very harmful to the environment.
- Mineral extraction: The removal of solid mineral resources from the earth, such as precious stones, ores, stones used for building and solid fossil fuels like coal.
- Mitigation: Actions taken to limit the long-term risk to human life and property from natural hazards, such as introducing targets to limit emissions or building earthquake-proof buildings.
- Natural greenhouse effect: The level of greenhouse gases in the atmosphere that occurs naturally. Without this, Earth’s average temperature would be well below freezing, and life as we know it would cease to exist.
- Natural hazard: An event that occurs naturally and has the potential to cause death and destruction. Examples of natural hazards are floods, volcanic eruptions, and earthquakes.
- Natural history: The study of the natural world (including wildlife, geology, and palaeontology) and its interactions, through observation, research, and communication.
- NDCs: An acronym for Nationally Determined Contributions - climate action plans for each of the countries that signed the Paris Agreement. They include policies and courses of action to reduce climate change.
- Net zero: A person, company or country is carbon-neutral if they balance the carbon dioxide they release into the atmosphere through their everyday activities with the amount they absorb or remove from the atmosphere. This is also called net zero carbon emissions, or net zero carbon, because overall no carbon dioxide is added to the atmosphere.
- Nomenclature: A formal system of names used to label taxonomic groups (see Taxonomy).
- Ocean acidification: A change in the pH of seawater, which is normally around neutral. Carbon dioxide that is present in the atmosphere dissolves into the ocean. This lowers the pH, making it more acidic.
- Ozone layer: A layer of ozone gas within the stratosphere - the second layer of the Earth’s atmosphere. It absorbs 98% of the Sun’s most harmful UV rays that cause sunburn and to human skin (and skin cancer) and damage to plants. CFCs have been identified as the main cause of damage to the ozone layer.
- Paris agreement: An international treaty on climate change, adopted in 2015 at COP21 in Paris and signed by 196 Parties. The agreement aims to limit global warming to well below 2 degrees Celsius (ideally 1.5 degrees Celsius) and encompasses climate change mitigation, adaptation, and finance.

- Recycling: The process of converting waste into reusable material.
- Renewable energy: Energy created from sources that can be naturally replenished, such as biomass, wind, and sunlight.
- Sea-level rise: An increase in the level of oceans, caused by the effects of global warming. Glaciers and ice sheets are melting and adding water to the ocean. The volume of the ocean is also expanding as the water warms.
- Secondary effects: The after-effects or indirect impacts of a natural hazard or event on people and property, for example the contamination of water supplies after an earthquake.
- Sky glow: The glow in the night sky caused by artificial lighting (see ALAN and light pollution). It is a form of pollution which can impact sleep patterns in humans and wildlife and affect the navigational ability of some species. It is also what prevents us from seeing the stars at night in built-up areas.
- Smog: A synonym for air pollution, combining the words ‘smoke’ and ‘fog.’
- Sustainability:Actions that meet the needs of the present without reducing opportunities for future generations.
- Taxonomy: The process and method of naming (see Nomenclature), describing, and classifying plants, animals, and microorganisms.
- Urbanisation: The process through which cities grow, and an increasing percentage of the population comes to live in towns and cities. The increased rate of urbanisation in the world today is driving an increase in emissions.
- Weather: Atmospheric conditions, such as rain or snow, happening in a place at a specific moment in time, as opposed to climate, which is how much, on average, a type of weather will occur over a longer period.
Suggestion for use in class
Poster
Print out a copy of the glossary to display in class, for students to refer to as and when they need it.
Match up activity
Use the glossary to play a matching game. Print out a set of the words and a separate set of the definitions, all on individual cards. You could focus on a specific topic (eg greenhouse gases) or look at all the definitions at once.
Challenge the students to work together in small teams to match up the words with the correct definitions. You could set a time limit for some added competition.
Mystery Word
Give the class a series of clues that relate to one of the definitions in the glossary. As they hear the clues, students can make guesses as to which definition it refers to. Encourage students to explain their reasoning.
As an extension task, students might like to work in small teams and come up with their own clues for each other.
