Climate change denial disorder is when someone is unwilling to accept that the climate is changing. This is usually because they don't believe in the scientific facts which show that the Earth is getting warmer due to human activities like burning fossil fuels and deforestation. People with this disorder don't understand the facts and continue to deny that the climate is changing and may even think it's impossible for it to happen. To help people with this disorder, it is important to provide them with facts, evidence, and explanations to make them understand why the climate is changing and what we can do to help.
