A major part of the world cannot understand why there are still peoples who deny the climate change when science has already proven that climate change is happening. All scientists agree that climate change is happening, and the effect is obvious: more frequent cyclones, huge fires and droughts, devastating floods, and other extreme events. So, what are the reasons that makes many people around the world to be blind for a problem?


This skepticism consists of 6 different elements that are covering each other, and their common union only reinforces the beliefs of such people. This list includes bias when looking for and relying on information that confirms our beliefs and choices. However, such information is false and not based on any scientific facts. In other words, if I believe that climate change is not happening, I will find a plethora of unapproved articles and shady YouTube videos made by the fake scientific community that will confirm the beliefs that I have already formed. Such people are not able to think critically and they are afraid of a different opinion. Other reasons include the elements such as the sense of the mass, ideologies, the Dunning–Kruger effect, the theories of conspiracy, and disinformation campaigns made by the fossil fuel industry.


The main researchers working in this field are Stephan Lewandowsky, Professor of Psychology; his colleague Dana Nuticelli; as well as Katherine Hayhoe, Professor of Atmospheric Phenomena; John Cook, a professor of cognitive sciences who set up the Skeptical Science website, which provides objective information to refute the arguments of climate change deniers; and professors of public psychology David Dunning and Justin Kruger who identified the well-known Dunning-Kruger effect. There are also organizations such as the Pew Research Center that regularly conducts worldwide research on climate change, covering demographic, political, and religious reasons.


Some people do not like government regulations, although many of them are necessary to combat climate change. Such people tend to be more suspicious of global warming because they just don’t like the decisions that need to be made. In this way, they fight against any political ideology.

A large proportion of the people are affected by the sense of the mass. Global warming, especially in the US, has become a key issue for Democrats who strongly support science and the evidence it provides. Meanwhile, the Republicans tend to vehemently reject scientific evidence. People blindly believe what they say, objective thinking does not remain here. The Dunning-Krueger effect is very important factor. The competence of many skeptics is very low, and they blindly believe in all the false information from shady sources, incompetent institutions, globally unrecognized scientists.

And the last crucial thing that characterizes people who deny climate change is conspiracy theories. Lewandowsky and Cook were the main authors of a study of various types of conspiracy who found a strong connection between belief in any one conspiracy theory and the fact that the science of climate change is merely a conspiracy deception. In other words, if you believe that the Earth is flat, then you will also believe that global warming is just a lie.
