(Source: Scripps Institution of Oceanography) Scientists the world over agree that climate change is real, it’s happening now, and it’s caused by the burning of fossil fuels. Still, there are a lot of myths being repeated about climate change, and even journalists can get taken in.

Most climate change myths have been perpetuated by fossil fuel companies, their political allies, and others with vested interests in the status quo. For decades, they’ve spent millions of dollars on advertising, think tank “studies,” and lobbying to confuse the public, policymakers, and the press and thereby forestall climate action. This has led some journalists to soften their coverage — for example, by not connecting climate change to extreme weather — leaving the public misinformed. This guide equips journalists to recognize and refute these myths and report the truth. The world is warming at a record pace, with unseasonable heat baking nearly every continent on Earth. April, the last month for which statistics are available, marked the 11th consecutive month the planet has set a new temperature high.

Experts say that is a clear sign the Earth’s climate is rapidly changing. But many believe – or at least say they believe – that climate change is not real, relying on a series of well-trodden myths to make their point. “Most of the world rightly acknowledges that climate change is real,” says Dechen Tsering, Acting Director of the Climate Change Division at the United Nations Environment Programme (UNEP). “But in many places, misinformation is delaying the action that is so vital to countering what is one of the greatest challenges facing humanity.” This month, delegates will be meeting in Bonn, Germany for a key conference on climate change. Ahead of that gathering, here is a closer look at eight common climate-related myths and why they are simply not true.

Myth #1: Climate change has always happened, so we should not worry about it. Many still believe that Earth’s climate is simply following a natural rhythm, dismissing the alarming changes we see as part of an ancient pattern. Yet, the 2023 Intergovernmental Panel on Climate Change (IPCC) report has delivered a startling truth: the current rate of warming is unmatched in at least 65,000 years. Human activities, mainly fossil fuel use and large-scale deforestation, are responsible for over 90% of global temperature increases since the 1950s. NASA’s latest data confirms that the past decade has shattered previous heat records, with average global temperatures rising faster than any other time in recorded history. While natural cycles like El Niño do affect weather, they cannot explain the persistent and accelerating warming we see today.

The fingerprints of human influence are visible in atmospheric CO₂ levels, which now exceed 420 ppm—a height not seen for millions of years. This evidence makes it clear: the dramatic shifts happening now are not just a blip in Earth’s history, but a direct consequence of human choices. It is a common refrain among skeptics that scientists are divided about the causes and reality of climate change. However, a groundbreaking 2024 survey in the journal Environmental Research Letters revealed that 97% of climate scientists worldwide agree: climate change is primarily driven by human activities. This consensus extends across major organizations such as NASA, the American Geophysical Union, and the World Meteorological Organization. A meta-analysis of 11,602 peer-reviewed studies published between 2012 and 2023 showed that fewer than 1% disputed human-driven climate change.

The persistent myth of disagreement often stems from misrepresentation in the media and deliberate campaigns to sow doubt. In reality, the scientific community has never been more united on this issue, and the evidence supporting their position is stronger than ever. The false notion of widespread division only serves to stall critical action and confuse the public. There are still claims, especially on some social media platforms, that climate change is a manufactured story or even a hoax. The Oxford Internet Institute’s 2023 study found that climate misinformation is widespread online and can heavily influence public perception. Yet, the evidence of climate change is impossible to ignore.

The World Meteorological Organization reported record-breaking numbers of heatwaves, wildfires, and hurricanes over the past two years, directly linked to shifting climate patterns. Entire communities have been displaced by rising sea levels and extreme flooding, such as those in Bangladesh and parts of California in 2024. Global biodiversity is in steep decline, with thousands of species threatened by habitat loss and changing environments. The overwhelming volume of peer-reviewed research and real-world disasters make the claim of a hoax not only false but dangerous, as it undermines efforts to address an urgent global crisis. Skeptics argue that wind, solar, and other renewables are too unreliable or insufficient to power modern society. However, the International Renewable Energy Agency (IRENA) reported in 2024 that global renewable energy generation grew by a staggering 10% over the previous year.

Solar power alone accounted for more than 30% of all new electricity generation worldwide. Countries like Denmark and Germany have surpassed 50% renewables in their energy mix, proving that large-scale transition is possible. Innovations in energy storage, such as next-generation lithium and solid-state batteries, have addressed the problem of intermittency. Smart grid technologies now allow for real-time balancing of supply and demand. The myth that renewables are inadequate is contradicted by data showing renewables are not just viable—they are central to the world’s fastest-growing energy markets. Some people believe that climate change is a challenge for future generations, not something that matters today.

This belief is contradicted by the United Nations Environment Programme (UNEP) 2024 report, which highlights that millions are already suffering from more intense droughts, floods, and deadly heatwaves. In 2023, Southern Europe experienced a devastating heatwave that sparked wildfires across Greece, Italy, and Spain, destroying entire communities and forcing mass evacuations. The World Health Organization estimated in 2024 that climate change contributes to over 250,000 additional deaths each year, largely from malnutrition, infectious diseases, and heat stress. Entire island nations like Tuvalu and the Maldives are threatened by rising sea levels, with some communities already planning to relocate. Food and water shortages are becoming more frequent, turning climate change into an immediate crisis rather than a remote threat. 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. The Earth is warming at a record pace. April marked the 11th consecutive month of new temperature highs. Global temperatures are the highest since records began, with the last 10 years being the warmest—clear evidence of climate change myths debunked by real data. The quick warming we see can’t be due to natural cycles. Changes that should take hundreds of thousands of years are happening in decades.

Human activity is responsible for almost all global warming over the past 200 years. This is mainly because of burning fossil fuels and releasing greenhouse gases. Earth’s climate has changed many times over 4.5 billion years. But today’s warming is unlike anything before. The planet’s temperature has risen by 1.1°C since the late 19th century. Most of this warming happened in the last 40 years.

This fast warming is due to greenhouse gas impacts from human actions. Especially from fossil fuel emissions from industrialization and modern life. The Earth has seen many climate changes, like ice ages and warmer periods. These changes were caused by things like the planet’s orbit and solar activity. But today’s climate crisis reality is different. It’s happening fast and is mainly caused by humans.
