Bjørn Lomborg:

Exaggeration also wears out the public’s willingness to tackle global warming. If the planet is doomed, people wonder, why do anything? A record 54% of American voters now believe the news media make global warming appear worse than it really is. A majority of people now believe — incorrectly — that global warming is not even caused by humans. In the United Kingdom, 40% believe that global warming is exaggerated and 60% doubt that it is man-made.
But the worst cost of exaggeration, I believe, is the unnecessary alarm that it causes — particularly among children. Recently, I discussed climate change with a group of Danish teenagers. One of them worried that global warming would cause the planet to “explode” — and all the others had similar fears.
In the US, the ABC television network recently reported that psychologists are starting to see more neuroses in people anxious about climate change. An article in the Washington Post cited nine-year-old Alyssa, who cries about the possibility of mass animal extinctions from global warming. In her words: “I don’t like global warming because it kills animals, and I like animals.” From a child who is yet to lose all her baby teeth: “I worry about [global warming] because I don’t want to die.”
