There has been an increase in the number of British people who are sceptical about climate change, a poll commissioned by BBC News has suggested.

It showed that 25% of those questioned did not think global warming was happening, an increase of 10% since a similar poll was conducted in November.  The percentage of respondents who said climate change was a reality had fallen from 83% in November to 75%.

The findings show that only 26% of people think “climate change is happening and is now established as largely man-made”, only 1% more than those who think there is no global warming.
