Bono and Al Gore in climate warning

Former US Vice President Al Gore and U2 frontman Bono have offered measured praise for efforts in tackling climate change and global poverty, but warned that conditions are not improving as much as they could.

At a session of the World Economic Forum in Davos, Switzerland, Mr Gore warned that the climate crisis was worsening.

"We could take the whole session talking just about the new scientific evidence of the last few weeks and months," said Mr Gore, who shared last year's Nobel Peace Prize for his efforts to fight climate change.
