Third Of UK Teenagers Believe Climate Change Exaggerated, Report Shows The Center for Countering Digital Hate (CCDH) has found that most climate denial videos on YouTube push the idea that climate solutions do not work, climate science and the climate movement are unreliable, or that the effects of global heating are beneficial or harmless.  The report also included the results of a nationally representative survey conducted by polling company Survation which found 31% of UK respondents aged 13 to 17 agreed with the statement “Climate change and its effects are being purposefully overexaggerated”. This rose to 37% of teenagers categorised as heavy users of social media, meaning they reported using any one platform for more than four hours a day.
