Global warming scepticism is rising, a major poll shows.
It found that 78 per cent of Britons believed the world's climate was changing, compared to 91 per cent five years ago.
The Ipsos Mori survey of 1,822 people for Cardiff University found 40 per cent believed the seriousness of global warming was exaggerated.
But the vast majority believed in climate change and that human activity was to blame.
Only 18 per cent thought it was mainly or entirely caused by natural processes.
