what is climate change and is it really a hoax bbc bitesize

World Environment Day encourages collective action to tackle the challenges that are facing the planet - with the focus in 2025 on plastic pollution. Another of those big challenges is climate change, which you have probably read about in stories ranging from reports of extreme weather to news about sea temperatures heating up. But as well as hearing the facts on this issue, you may have also come across some fake news about the topic. In fact, some people even call climate change itself ‘fake news’, even when it’s been proven to be real. Why does this happen? Watch this TikTok from the BBC Verify team, who explain why climate change is real and define what global warming is.

Is climate change real? Maybe you think climate change is a hoax. But the science couldn't be clearer. Global warming is happening and the way we live is making things worse. Human activities are causing world temperatures to rise, posing serious threats to people and nature. Things are likely to worsen in the coming decades, but scientists argue urgent action can still limit the worst effects of climate change.

Climate change is the long-term shift in the Earth's average temperatures and weather conditions. The world has been warming up quickly over the past 100 years or so. As a result, weather patterns are changing. Since the 1980s, each decade has been warmer than the previous one, the UK Met Office says. It starts with a whisper—rising seas nibbling away at coastlines, warmer winters replacing the cold snaps of old, forests catching fire in places that once stood serene and damp. Somewhere, a polar bear drifts on a dwindling ice floe.

Elsewhere, a farmer stares at the cracked, parched earth that once yielded life. And everywhere, people are asking: Is this real? Is it natural? Is it too late? Global warming. For decades, those two words have hovered in the background of public discourse, growing louder with each passing year.

Yet for every scientist shouting the alarm, there’s a social media post casting doubt. Climate change is real, they say. No, it’s a hoax. It’s human-caused. No, it’s natural. The confusion is not surprising.

When fear, politics, and profit collide, the truth often gets buried. But today, we dig it out. Not with shouting, but with clarity. Not with fear, but with facts. This is a journey through science and storytelling, separating myth from reality, to help you understand what global warming really is—and why the truth matters now more than ever. The story of global warming is ancient, stretching back far before the Industrial Revolution.

Our planet’s climate has never been static. It has swung from ice ages to tropical epochs over millions of years, driven by natural factors like volcanic activity, solar radiation, and changes in Earth’s orbit. But something different began in the late 18th century. Humanity discovered coal, then oil, then gas. We built engines, powered factories, lit up cities, and transformed the world. And in doing so, we began to alter the chemistry of our atmosphere in ways nature never had.

Climate change is not a hoax. The overwhelming consensus among climate scientists, supported by decades of empirical data and rigorous research, confirms that Earth’s climate is changing at an unprecedented rate, primarily due to human activities, particularly the burning of... While contrarian voices and isolated studies may suggest otherwise, these claims are often based on misinterpretations of data, flawed methodologies, or outright disinformation campaigns designed to undermine public understanding and delay action on climate... This article will address common misconceptions surrounding climate change, examine the overwhelming scientific evidence, and answer frequently asked questions to clarify why the assertion of climate change being a hoax is demonstrably false. The scientific evidence supporting climate change is vast and multifaceted. It includes observations of rising global temperatures, melting glaciers and ice sheets, rising sea levels, changes in precipitation patterns, and increased frequency and intensity of extreme weather events.

These observations align with climate models that accurately predict the impacts of increased greenhouse gas concentrations in the atmosphere. The greenhouse effect is a natural process that warms the Earth’s surface. Certain gases in the atmosphere, such as carbon dioxide, methane, and nitrous oxide, trap heat radiated from the Earth, preventing it from escaping into space. This process is essential for maintaining a habitable temperature on Earth. However, human activities have significantly increased the concentration of these greenhouse gases in the atmosphere, leading to an enhanced greenhouse effect and a warming planet. Numerous independent datasets, including those compiled by NASA, NOAA, and the UK Met Office, show a consistent trend of rising global temperatures over the past century.

The last decade has been the warmest on record, and 2023 is on track to be the hottest year ever recorded. This warming is not uniform across the globe, with some regions experiencing more significant temperature increases than others. As our planet confronts the repercussions of environmental degradation, the debate surrounding climate change rages on. Is climate change truly a hoax, as some skeptics assert? In this exploration, we will scrutinize the assertions of those who contend that climate change is a hoax, carefully examining the evidence to reveal the truth behind this pivotal global concern. Some people strongly believe that climate change is just a made-up story.

Skeptics say that the Earth’s natural ups and downs, not human actions, are causing the changes we see. They point to times in history when the Earth’s temperature went up and down, suggesting today’s climate change is just part of a natural cycle. It’s good to listen to these different viewpoints because they add variety to the conversation. But, it’s also important to dig a bit deeper. Some skeptics focus on the Earth’s past climate changes, saying they’re normal. But recognizing these opinions isn’t just about acknowledging different views, it’s a chance to learn more together.

While thinking about these skeptical ideas, we see that lots of things play a part in the climate change talk. But, looking into these views doesn’t mean we should ignore what most scientists agree on. Actually, understanding how nature and human actions connect helps us have a more detailed and full picture of what’s happening with climate change. It’s by looking closely at these details that we can understand the various sides of the climate change discussion with a smart eye and a well-informed view. Contrary to claims of a hoax, the overwhelming majority of climate scientists agree that climate change is real and primarily driven by human activities. Rigorous research and peer-reviewed studies consistently support the conclusion that rising greenhouse gas emissions, such as carbon dioxide and methane, contribute to the warming of our planet.

Climate change refers to the shift in the Earth’s usual weather conditions over many years. Our world has been getting hotter due to things humans are doing, like burning huge amounts of fossil fuels, cutting down too many trees and over-farming crops and animals. Climate change is the result of these actions and it's already putting humans, wildlife and the planet at risk. But it's not too late. By working together, everyone can help. Our planet needs us.

It's Fatima calling… from the future! She has climate change on her mind and an important message to share with you. Human activities are causing world temperatures to rise, posing serious threats to people and nature. Things are likely to worsen in the coming decades, but scientists argue urgent action can still limit the worst effects of climate change. Climate change is the long-term shift in the Earth's average temperatures and weather conditions. The world has been warming up quickly over the past 100 years or so.

As a result, weather patterns are changing. Since the 1980s, each decade has been warmer than the previous one, the UK Met Office says. Global warming is often referred to in the news or in conversations about the weather. Environmental scientist Laura Young explains how human activity is causing changes in the Earth’s atmosphere and what impact this has on the climate and living things. Global warming is the unusually fast increase in the Earth’s average surface temperature and is caused by greenhouse gases like carbon dioxide and methane being released into the atmosphere. When sent out into the air, these potentially harmful gases are known as emissions.

Throughout history, the Earth has warmed and cooled over long periods of time. But in the past 100 years, human activity has caused the Earth’s atmosphere and our climate to change more quickly. When fossil fuels, like oil, gas and coal, are burned, lots of greenhouse gases are released into our atmosphere changing the way it’s made up. Weather and climate are not the same thing. Weather can change suddenly, while the climate is the type of weather an area has over a long period of time. Different places across the world will experience different climates – some parts of our planet will see snowy and cold weather, some will be warm and dry, while others will enjoy a little bit...

The climate doesn’t always stay the same. It usually changes naturally and slowly but recently it has been changing very quickly. Gases that we release into the atmosphere can cause the climate to change. Carbon dioxide - also known as CO₂ - is produced when we burn fossil fuels like coal, oil and gas. Fossil fuels are used to power cars and aeroplanes, and to produce electricity for homes and the factories that make our toys, clothes and electronic gadgets. When carbon dioxide enters the atmosphere it causes the greenhouse effect.
