The BBC re-edited an episode of Sir David Attenborough's Africa series to remove a disputed claim over climate change.
In the episode, broadcast on Wednesday, Sir David told viewers: "Some parts of the continent have become 3.5C hotter in the past 20 years", but the BBC has since admitted that is "disputable".
The line was removed from the repeat episode and the re-edited version has replaced the original show on the iPlayer.
