Global warming cynicism rises in face of stronger evidence

A significant proportion of the population have become more sceptical about climate change and the link with man-made emissions of greenhouse gases despite the fact that the scientific evidence has become stronger.

A survey of public opinion has found that 29 per cent of people believe claims that human activities are changing the climate are exaggerated compared with 15 per cent of respondents to a similar survey carried out in 2003.

About one in five people are uncertain about whether climate change is really happening, about the same proportion who had the same view in 2003, according to the survey carried out by Cardiff University researchers.
