Attenborough to G7: We need the will to tackle climate change

''We know in detail what is happening to our planet, and we know many of the things we need to do during this decade," he said in a recorded video address.

"Tackling climate change is now as much a political and communications challenge as it is a scientific or technological one. We have the skills to address it in time, all we need is the global will to do so."

G7 leaders agreed on Sunday to raise their contributions to meet an overdue spending pledge of $100 billion a year to help poorer countries cut carbon emissions and cope with global warming, but campaigners said firm cash promises were missing.
