David Attenborough: 'We must act now on climate change'

Speaking on Tuesday (October 25) ahead of the United Nations climate change summit in Scotland, Attenborough also said richer nations had a moral responsibility to act.

Britain has cast the COP26 climate conference, which begins in Glasgow on October 31, as the last big chance to slow rising temperatures, and hopes to persuade leaders to adopt tougher climate targets.

Attenborough, 95, told the BBC it would be "really catastrophic" if richer nations failed to support poorer ones, and time was running out.

British Prime Minister Boris Johnson said it was "touch and go" as to whether COP26 would succeed in securing the requirements needed to limit the rise in the average global temperature to 1.5 degree Celsius above pre-industrial levels and to achieve net-zero carbon emissions by 2050.
