Television shows should have more plot lines and references to climate change to help tackle the issue, according to Bafta.

The British Academy of Film and Television Arts says TV can help change people's attitudes towards the planet.

It cites successes from previous initiatives based around health and social issues.

The call to action comes after Bafta analysed a year's worth of subtitles from 40 TV channels.

It found that references to climate change lagged far behind such terms as "beer" or "sex".

What has Bafta found?

In its "Subtitles to Save the World" report, the academy analysed 128,719 non-news programmes from across the BBC, ITV, Channel 4 and Sky between September 2017 and September 2018.

In total, 25 words related to the environment were tracked including "food waste", "electric car" and "green energy".

The document found that "climate change" had 3,125 mentions - far behind such terms as "beer" (21,648), "dog" (105,245), "tea" (60,060) and "sex" (56,307).

"Climate change" references came up more or less as often as "zombie", "urine" or "rhubarb".

The report also found that the possible solutions to reducing individuals' carbon footprints which were mentioned the most in programmes were not the ones that have the biggest impact.

Words like "vegan" and "vegetarian" were used more often than words like "green energy" and "hybrid cars". However, food is responsible for 12% of a person's carbon footprint, and experts say we will need to eat less meat if we want to meet climate targets.

The report was prepared by Bafta and was also supported by analysis from Deloitte.

Reacting to the document's findings, Bafta's chairwoman Dame Pippa Harris said: "The TV industry's call to address climate change is clear.

"It's time to write a different script," she said, urging the industry to "use powerful human stories to connect audiences with the world around them".

Meanwhile, the academy's head of industry sustainability, Aaron Matthews, told the BBC that TV programmes did talk about the environment "in some way, but at quite a low level at the moment".

"So, obviously, no zombie apocalypse on the horizon, but a climate change one," he said.

How much of an influence is television?

Television is still seen as a very powerful medium which can change the public's opinion of health and social issues.

Blue Planet II opened people's eyes to the problem of plastic pollution.

And when soap operas such as EastEnders tackle health and social issues, charities often receive surges in calls for help.

Research by the charity Mind found that one in four people who saw a mental health storyline in a soap, contacted a friend, colleague or loved one. In addition, 16% sought professional help themselves.

But when it comes to issues such as sustainability and climate change, some will question whether this can be done without putting off viewers.

Satirist and writer Charlie Brooker has explored climate change in his show Black Mirror, but admits including the subject in plotlines "is a very, very tough nut to crack".

He says: "It is a difficult thing to see a simple story.

"You tend to get things like Game of Thrones where the dead at the wall and 'winter is coming' was kinda playing out like a metaphor for climate change with everybody warring and getting caught up with their own political squabbles while facing annihilation.

"I never know quite how much drama can change people's opinions and behaviour."

But screenwriter Lisa Holdsworth says little references - like showing people recycling and talking about environmental issues - can make a difference.

"We're beginning to see the real-life effects of climate change on people who've no choice but to bear the brunt of it and, I think, if television and drama are not reflecting that, we're not doing our job properly."

In a statement, the BBC said it was "helping to arm audiences with the facts on climate change and sustainability".

It added: "We will be commissioning more programmes which challenge and inform audiences, while building up our collection of online resources and archive about our planet and the environment in which we live."

Sky said it supports the new research and says its "channels regularly show content that illustrates the breadth of the challenge we face in order to help protect our planet."

"Broadcasters have an incredible opportunity to highlight environmental issues and inspire public change."

Chief of Staff at Channel Four, Lynette Huntley, said "this fascinating piece of research will help us identify what more we can do to challenge perception and inspire change around sustainability."

BBC News has contacted ITV for a comment and is still waiting to hear back.

What do all the terms mean?

Skip to main story
  • 1.5 degrees

    Keeping the rise in global average temperature below 1.5 degrees Celsius will avoid the worst impacts of climate change, scientists say. That’s compared with ‘pre-industrial’ times. The world has already warmed about 1C since then.

  • 2 degrees

    The original target for limiting the rise in global average temperature. Recent research points to 1.5 degrees being a far safer limit.

  • 3 degrees

    The current likely rise in average global temperature by the year 2100 if countries keep their promises to cut emissions of greenhouse gases, which are driving climate change.

  • 4 degrees

    A prediction of the likely rise in average temperature by 2100 if no further action is taken. This would see major sea-level rise, with many coastal areas becoming uninhabitable, as well as regular severe heatwaves and massive disruption to agriculture.

  • Adaptation

    An action that helps cope with the effects of climate change - for example building houses on stilts to protect from flooding, constructing barriers to hold back rising sea levels or growing crops which can survive high temperatures and drought.

  • AGW

    Stands for 'Anthropogenic Global Warming', which means the rise in temperatures caused by human activity like the burning of fossil fuels such as coal and oil. This produces carbon dioxide and other so-called greenhouse gases, which trap heat in the atmosphere and cause the planet to become warmer. This is in addition to changes in the climate which happen because of natural processes.

  • Arctic ice

    The Arctic Ocean freezes in winter and much of it then thaws in summer, and the area thawing has increased by 40% over the past few decades. The Arctic region is warming twice as fast as the rest of the planet.

  • Attribution

    Attribution is the process by which scientists try to explain whether climate change has made a particular weather event - like a heatwave - more likely.

  • Average temperature

    The average temperature of the world is calculated with the help of temperature readings taken from weather stations, satellites and ships and buoys at sea. Currently it stands at 14.9C.

  • BECCS

    Stands for 'Bio Energy with Carbon Capture and Storage'. It's the name for a system in which crops are grown (which draws in carbon dioxide from the air) and when they are burned to make electricity, carbon emissions are captured and then stored. Scientists see this is a key way to keep the lights on while not adding to global warming, but the technology is in its infancy.

  • Biofuel

    A fuel derived from renewable, biological sources, including crops such as maize, palm oil and sugar cane, and some forms of agricultural waste.

  • Biomass

    Biomass is plant or animal material used to produce energy or as raw materials for other products. The simplest example is cow dung; another is compressed wood pellets, which are now used in some power stations.

  • Carbon

    Carbon is a chemical element which is sometimes described as a building block for all life on Earth because it is found in most plant and animal life. It is also found in fuels like petrol, coal and natural gas, and when burned, is emitted as a gas called carbon dioxide.

  • Carbon capture

    The trapping and removal of carbon dioxide gas from the air. The gas can then be reused, or injected into deep underground reservoirs. Carbon capture is sometimes referred to as geological sequestration. The technology is currently in its infancy.

  • Carbon dioxide

    Carbon dioxide is a gas in the Earth's atmosphere. It occurs naturally and is also a by-product of human activities such as burning fossil fuels. It is the principal greenhouse gas produced by human activity.

  • Carbon footprint

    The amount of carbon emitted by an individual or organisation in a given period of time, or the amount of carbon emitted during the manufacture of a product.

  • Carbon neutral

    A process where there is no net release of carbon dioxide (CO2). For example, growing biomass takes CO2 out of the atmosphere, while burning it releases the gas again. The process would be carbon neutral if the amount taken out and the amount released were identical. A company or country can also achieve carbon neutrality by means of carbon offsetting. The phrase 'net zero' has the same meaning.

  • Carbon offsetting

    Carbon offsetting is most commonly used in relation to air travel. It allows passengers to pay extra to help compensate for the carbon emissions produced from their flight. The money is then invested in environmental projects - like planting trees or installing solar panels - which reduce the carbon dioxide in the air by the same amount. Some activists have criticised carbon offsetting as an excuse to continue polluting, arguing that it does little to change behaviour.

  • Carbon sink

    Anything which absorbs more carbon dioxide than it emits. In nature, the main carbon sinks are rainforests, oceans and soil.

  • CCU

    Stands for ‘Carbon Capture and Utilisation’. This consists of using technology to draw carbon dioxide from the atmosphere and turn it into products like biofuels and plastics.

  • Climate change

    A pattern of change affecting global or regional climate, as measured by average temperature and rainfall, and how often extreme weather events like heatwaves or heavy rains happen. This variation may be caused by both natural processes and by humans. Global warming is an informal term used to describe climate change caused by humans.

  • Climate model

    Climate models are computer simulations of how the atmosphere, oceans, land, plants and ice behave under various levels of greenhouse gases. This helps scientists come up with projections for what Earth will be like as global warming continues. The models do not produce exact predictions, but instead suggest ranges of possible outcomes.

  • Climate negotiations

    Climate negotiations take place every year as the United Nations brings governments together to discuss action to stop climate change. The goal is usually a collective agreement to reduce carbon emissions by certain dates. The latest of these is the Paris Agreement of 2015 which set the targets of limiting warming to 2C or 1.5C if possible. Negotiations are always difficult because many countries are heavily dependent on fossil fuels and worry about the effects of any change on their economies.

  • CO2

    Means carbon dioxide, a naturally occurring gas which is also a major product of human activity such as burning fossil fuels. Increasing levels of carbon dioxide in the atmosphere means more heat is retained, causing the planet to warm up.

  • COP

    Stands for 'Conference of the Parties'. It is the name for the annual UN negotiations on climate change under what is called the United Nations Framework Convention on Climate Change (see UNFCCC). The aim is to prevent dangerous human interference with the climate.

  • Copenhagen

    A UN climate summit was held in Copenhagen in 2009 which descended into acrimony and ended with countries only agreeing a non-binding accord that climate change was "one of the greatest challenges of the present day". The event is widely regarded as one of the least productive since climate negotiations began.

  • Coral bleaching

    Coral bleaching refers the change in colour of coral reefs when the ocean temperature rises above a certain level, forcing the corals to eject the algae they normally co-exist with - this turns them white. Coral can recover if the water cools, but lasting damage can be done if it remains too hot.

  • Deforestation

    The clearing of forests to make way for farming such as soy crops to feed livestock or palm oil for consumer products. This releases significant levels of carbon dioxide as trees are burned.

  • Deniers

    Climate deniers believe that climate change is only taking place because of natural processes and that human activity has no role. They dispute the work of many thousands of experts around the world, whose research has been peer-reviewed and published and is based on research stretching back more than a century.

  • Emissions

    Emissions are any release of gases such as carbon dioxide which cause global warming, a major cause of climate change. They can be small scale in the form of exhaust from a car or methane from a cow, or larger-scale such as those from coal-burning power stations and heavy industries.

  • Extreme weather

    Extreme weather is any type of unusual, severe or unseasonal weather. Examples could be major heat waves, with temperature records broken, extended droughts as well as cold spells and heavier than usual rainfall. Scientists predict that extreme weather will become more common as the world becomes warmer.

  • Feedback loop

    In a feedback loop, rising temperatures change the environment in ways that affect the rate of warming. Feedback loops can add to the rate of warming or reduce it. As the Arctic sea-ice melts, the surface changes from being a bright reflective white to a darker blue or green, which allows more of the Sun’s rays to be absorbed. So less ice means more warming and more melting.

  • Fossil fuels

    Fuels such as coal, oil and natural gas were formed when tiny plants and animals flourished in the ancient past, absorbing carbon from the atmosphere, before dying and being crushed over millions of years. When burned, they release carbon dioxide.

  • Geo-engineering

    Geo-engineering is any technology which could be used to halt or even reverse climate change. Examples range from extracting carbon dioxide from the atmosphere and storing it underground, to more far-fetched ideas such as deploying vast mirrors in space to deflect the Sun's rays. Some scientists say geo-engineering may prove essential because not enough is being done to reduce emissions of greenhouse gases. Others warn that the technologies are unproven and could have unforeseen consequences.

  • Global temperature

    Usually a reference to temperature averaged across the entire planet.

  • Global warming

    The steady rise in global average temperature in recent decades, which experts say is mostly caused by human-produced greenhouse gas emissions. The long-term trend continues upwards with 2015, 2016, 2017 and 2018 being the warmest years on record.

  • Green energy

    Green energy, sometimes called renewable energy, is generated from natural, replenishable sources. Examples are wind and solar power as well as biomass, made from compressed wood pellets.

  • Greenhouse gases

    Natural and human-produced gases that trap heat in the atmosphere and warm the surface. The Kyoto Protocol restricts emissions of six greenhouse gases: carbon dioxide, nitrous oxide, methane, perfluorocarbons, hydrofluorocarbons, and sulphur hexafluoride.

  • Gulf Stream

    The Gulf Stream is a warm ocean current which originates in the Gulf of Mexico and flows up the east coast of the United States and across the Atlantic Ocean. Scientists believe Europe would be significantly cooler without it. There is a fear that the stream could be disrupted if rising temperatures melt more polar ice, bringing an influx of freshwater.

  • Hydrocarbon

    A hydrocarbon is a substance consisting entirely of hydrogen and carbon. The major fossil fuels - coal, oil and gas - are hydrocarbons and as such, are the main source of emissions linked to climate change.

  • IPCC

    The Intergovernmental Panel on Climate Change is a scientific body established by the United Nations and the World Meteorological Organization. Its role is to examine and assess the latest scientific research into climate change. Its report in 2018 warned that the rise in global temperatures should be limited to 1.5C to avoid dangerous impacts.

  • Jetstream

    A jetstream is a narrow band of fast-flowing air at high altitude which acts as major influence on the weather. Jetstreams could be disrupted by warming in polar regions, and this may make extreme weather like Europe’s hot summer of 2018 more common.

  • Kyoto Protocol

    A set of rules agreed at Kyoto in Japan in 1997, in which 84 developed countries agreed to reduce their combined emissions by 5.2% of their level in 1990.

  • Lukewarmers

    A term used to describe people who believe that climate change is real, and being driven by human activity, but that its effects will not be as bad as predicted by scientists.

  • Methane

    Methane is a gas which traps about 30 times more heat than carbon dioxide. It is produced by human activity from agriculture – cows emit large amounts – as well as waste dumps and leaks from coal mining. Methane is also emitted naturally from wetlands, termites and wildfires. One big concern is that carbon held in frozen ground in arctic regions will be released as methane as temperatures rise and the ground thaws. This could cause extra, unpredictable global warming.

  • Mitigation

    Action that will reduce human-driven climate change. This includes reducing greenhouse gas emissions by switching to renewable power, or capturing greenhouse gases from the atmosphere by planting forests.

  • Net zero

    A term used to describe any process where there is no net release of carbon dioxide (CO2). For example, growing biomass takes CO2 out of the atmosphere, while burning it releases the gas again. The process would be net zero if the amount taken out and the amount released were identical. A company or country can also achieve net zero by means of carbon offsetting. Net zero processes or manufactured items are sometimes also describbed as being 'carbon neutral'.

  • Ocean acidification

    The ocean absorbs approximately a quarter of human produced carbon dioxide (CO2) from the atmosphere, which helps to reduce the effect of climate change. However, when the CO2 dissolves in seawater, carbonic acid is formed. Carbon emissions from industry in the last 200 years have already begun to alter the chemistry of the world’s oceans. If this trend continues, marine creatures will find it harder to build their shells and skeletal structures, and coral reefs will be killed off. This would have serious consequences for people who rely on them as fishing grounds.

  • Ozone layer

    The ozone layer is part of Earth's high atmosphere which contains a large concentration of gas molecules comprising three oxygen atoms called ozone. Ozone helps filter out harmful ultraviolet light from the Sun, which can increase the risk of skin cancer. In the 1980s and 1990s, industrial gases called chlorofluorocarbons (or CFCs) were banned because they damaged the ozone layer. These gases are also potent greenhouse gases, contributing to global warming.

  • PPM / ppm

    An abbreviation for 'parts per million', used to describe the concentration of a gas such as carbon dioxide in the atmosphere. The Intergovernmental Panel on Climate Change (IPCC) suggested in 2007 that the world should aim to stabilise greenhouse gas levels at 450 ppm CO2 equivalent in order to avert dangerous climate change. Some scientists, and many of the countries most vulnerable to climate change, argue that the safe upper limit is 350ppm. Modern levels of CO2 broke through 400ppm (at the Mauna Loa Laboratory in Hawaii) in 2013, and continue to climb at about 2-3ppm per year.

  • Pre-industrial

    Scientists use a baseline with which to compare the modern rise in temperatures on Earth. The baseline often quoted is 1850-1900, and global temperatures have risen by about 1C since then. The reality, of course, is that industry actually got going much earlier, but there is nonetheless a perceptible uptick in the levels of CO2 and other greenhouse gases in the atmosphere by 1850-1900 and the period is deemed therefore to be a useful marker.

  • Renewable energy

    Normally refers to energy sources such as biomass (such as wood and biogas), the flow of water, geothermal (heat from within the earth), wind, and solar.

  • Runaway climate change

    Describes how the climate change may suddenly change after passing a 'tipping point', making it even harder to stop or reverse. In 2018, the IPCC said that global emissions must be reduced by 45% by 2030, and to net zero by 2050 to have 50% chance of limiting temperature rises to 1.5C this century.

  • Sea ice

    Sea-ice is found in polar regions. It grows in extent and thickness in autumn and winter, and melts in spring and summer. The amount of sea-ice in the Arctic is seen as a key indicator of climate trends because the region is warming faster than most other locations on Earth. The smallest ever extent (in the satellite era) of Arctic sea-ice was recorded in September 2012. The 3.41 million square kilometers was 44% below the 1981-2010 average.

  • Sea level rises

    Rising sea levels are predicted to be one of the most drastic impacts of climate change. In this context, there are two main causes for sea-level rise: (1) the expansion of seawater as the oceans warm; and (2) the run-off into the ocean of water from melting ice sheet and glaciers. Current sea levels are about 20cm higher on average than they were in 1900. Year on year, sea levels are presently going up by just over 3mm.

  • Sustainability

    Sustainability means consuming the planet's resources at a rate at which they can be replenished. It's sometimes known as 'sustainable development'. Types of renewable energy such as solar or wind power are described as sustainable, while using wood from managed forests where trees are replanted according to how many are cut down is another example.

  • Tipping point

    Describes how the climate may suddenly change after passing a ‘tipping point’, making it even harder to stop or reverse. Scientists say it is urgent that policy-makers halve global carbon dioxide emissions by 2030 or risk triggering changes that could be irreversible.

  • UNFCCC

    Stands for the United Nations Framework Convention on Climate Change. This is an international treaty, signed at the Earth Summit in Rio de Janeiro in 1992, which stated that countries should work to stabilise greenhouse gas concentrations in the atmosphere to avoid dangerous climate change.
