The five corrupt pillars of climate change denial
Source: The Conversation, Mark Maslin

The fossil fuel industry, political lobbyists, media moguls and individuals have spent the past 30 years sowing doubt about the reality of climate change - where none exists. The latest estimate is that the world's five largest publicly-owned oil and gas companies spend about US$200 million a year on lobbying to control, delay or block binding climate policy.

Their hold on the public seems to be waning. Two recent polls suggested over 75% of Americans think humans are causing climate change. School climate strikes, Extinction Rebellion protests, national governments declaring a climate emergency, improved media coverage of climate change and an increasing number of extreme weather events have all contributed to this shift. There also seems to be a renewed optimism that we can deal with the crisis.

But this means lobbying has changed, now employing more subtle and more vicious approaches – what has been termed as "climate sadism". It is used to mock young people going on climate protests and to ridicule Greta Thunberg, a 16-year-old young woman with Asperger's, who is simply telling the scientific truth.

At such a crossroads, it is important to be able to identify the different types of denial. The below taxonomy will help you spot the different ways that are being used to convince you to delay action on climate change.


1) Science Denial

This is the type of denial we are all familiar with: that the science of climate change is not settled. Deniers suggest climate change is just part of the natural cycle. Or that climate models are unreliable and too sensitive to carbon dioxide.

Some even suggest that CO₂ is such a small part of the atmosphere it cannot have a large heating affect. Or that climate scientists are fixing the data to show the climate is changing (a global conspiracy that would take thousands of scientists in more than a 100 countries to pull off).

All these arguments are false and there is a clear consensus among scientists about the causes of climate change. The climate models that predict global temperature rises have remained very similar over the last 30 years despite the huge increase in complexity, showing it is a robust outcome of the science

2) Economic Denial 

The idea that climate change is too expensive to fix is a more subtle form of climate denial. Economists, however, suggest we could fix climate change now by spending 1% of world GDP. Perhaps even less if the cost savings from improved human health and expansion of the global green economy are taken into account. But if we don't act now, by 2050 it could cost over 20% of world GDP.

We should also remember that in 2018 the world generated US$86,000,000,000,000 and every year this World GDP grows by 3.5%. So setting aside just 1% to deal with climate change would make little overall difference and would save the world a huge amount of money. What the climate change deniers also forget to tell you is that they are protecting a fossil fuel industry that receives US$5.2 trillion in annual subsidies – which includes subsidised supply costs, tax breaks and environmental costs. This amounts to 6% of world GDP.

3) Humanitarian Denial 

Climate change deniers also argue that climate change is good for us. They suggest longer, warmer summers in the temperate zone will make farming more productive. These gains, however, are often offset by the drier summers and increased frequency of heatwaves in those same areas. For example, the 2010 "Moscow" heatwave killed 11,000 people, devastated the Russian wheat harvest and increased global food prices.

4) Political Denial

5) Crisis Denial

The final piece of climate change denial is the argument that we should not rush into changing things, especially given the uncertainty raised by the other four areas of denial above. Deniers argue that climate change is not as bad as scientists make out. We will be much richer in the future and better able to fix climate change. They also play on our emotions as many of us don't like change and can feel we are living in the best of times – especially if we are richer or in power.

But similarly hollow arguments were used in the past to delay ending slavery, granting the vote to women, ending colonial rule, ending segregation, decriminalising homosexuality, bolstering worker's rights and environmental regulations, allowing same sex marriages and banning smoking.
