Throughout history, humanity has fought against preconceived ideas that resisted scientific evidence. We remember the resistance to accept that the Earth revolves around the Sun, or the controversy generated by Darwin's theory of evolution.
Today, however, we are faced with a paradox: in the information age, where scientific knowledge is more accessible than ever, we are witnessing a resurgence of denialist theories that reject proven facts, especially regarding Climate Change. And the most worrying thing is that this denial, often driven by political and economic interests, endangers the future of our planet.
Climate Change is an undeniable reality. The year 2024 has seen record temperatures, confirming the trend towards global warming accelerated by human activity, mainly due to the use of fossil fuels for more than a century. The scientific community, through the Intergovernmental Panel on Climate Change (IPCC), has provided overwhelming evidence demonstrating the cause-effect relationship between greenhouse gas emissions and the increase in global temperature.
The effects of this change are already visible: melting of glaciers, rising sea levels, more frequent and intense extreme weather events (heat waves, droughts, floods, forest fires), alterations in ecosystems, and a long etcetera that threatens the stability of our planet and life as we know it.

However, despite the overwhelming scientific evidence, denialist voices persist that question the anthropogenic origin of climate change. Their arguments, often fallacious and unscientific, are based on distrust of science, conspiracy theories, and data manipulation. Some argue that the climate has always changed, which is true, but they ignore the unprecedented speed at which current change is occurring, driven by human activity.
Others point to dissident scientists, often without the necessary expertise in climatology, to sow doubt and confusion. Ultimately, these denialist strategies seek to maintain the status quo, protect economic interests linked to fossil fuels, and delay the adoption of urgent measures to mitigate Climate Change.
Disinformation runs rampant on social media, amplified by algorithms that prioritize virality over veracity. Pressure groups with strong financial resources finance disinformation campaigns to sow doubt and confusion in public opinion, presenting Climate Change as a controversial theory rather than a proven scientific fact.
This strategy, reminiscent of the tactics used by the tobacco industry to deny the harmful effects of tobacco, seeks to lull the population, demobilize climate action, and delay the transition to a sustainable energy model.
It is true that steps are being taken towards sustainability. Investment in renewable energy is growing, and more and more countries are committing to reducing their emissions. However, the speed of these changes is insufficient in the face of the urgency of the problem. We need a radical transformation of our energy system, a decisive commitment to energy efficiency, and a profound change in our consumption patterns. And to achieve this change, it is crucial that society relies on science, on proven knowledge, and not on the self-interested opinions of pressure groups seeking to perpetuate an unsustainable model.
Will we succeed? The answer, unfortunately, is uncertain. Time is running out, and the window of opportunity to avoid the worst scenarios of climate change is closing rapidly. The fight against climate denialism is a crucial battle that we must fight.
Education, scientific outreach, and critical thinking are our best weapons. The future of our planet depends on our ability to distinguish truth from lies, and to act with the urgency that the situation demands. We cannot afford to play with matches while the Earth burns.
