Public conviction about the threat of climate change has declined sharply after months of questions over the science and growing disillusionment with government action, a leading British poll has found.
The proportion of adults who believe climate change is “definitely” a reality dropped by 30% over the last year, from 44% to 31%, in the latest survey by Ipsos Mori.
Overall around nine out of 10 people questioned still appear to accept some degree of global warming. But the steep drop in those without doubts will raise fears that it will be harder to persuade the public to support actions to curb the problem, particularly higher prices for energy and other goods.
The true level of doubt is also probably underestimated because the poll only questioned 16 to 64-year-olds. People over 65 are more likely to be sceptical, the researchers said.
