Public support for a strong global deal on climate change has declined, according to a poll carried out in 20 countries.
Only four now have majorities in favour of their governments setting ambitious targets at a global conference in Paris.
In a similar poll before the Copenhagen meeting in 2009, eight countries had majorities favouring tough action.
The poll has been provided to the BBC by research group GlobeScan.
Just under half of all those surveyed viewed climate change as a “very serious” problem this year, compared with 63% in 2009.
