Attenborough said the climate emergency “comes down to a single number: the concentration of carbon in our atmosphere.” Accompanied by footage showing the atmospheric concentration of carbon dioxide at its current level of 414 parts per million, Attenborough pointed out that of CO2 “greatly determines global temperature … and the changes in that one number is the clearest way to chart our own story.”Declaring that humanity was in “trouble” and the story was not merely one of instability, it was also about inequality, he pointed out “Those who’ve done the least to cause this problem are being the hardest hit,” he said. Attenborough, who wrote and presented the award-winning Life series of nature documentaries, is one of the most respected voices in the environmental movement. He began work with the BBC in 1952 and continues to produce films, including A Life On Our Planet on Netflix, which focused on the environmental destruction he witnessed over the course of his life. Making a passionate plea for world leaders to “rewrite our story,” he warned that those who could be impacted by catastrophic climate change were not “some imagined generation” but “young people alive today.” “There was still time to turn “tragedy into triumph…We are, after all, the greatest problem-solvers to have ever existed on Earth. We now understand this problem, We know how to stop the number rising, and put it in reverse. We must halve carbon emissions this decade. We must recapture billions of tonnes of carbon from the air. We must fix our sights on keeping 1.5 degrees within reach”, he said.The famous environmental activist and broadcaster said that if working apart we are a force powerful enough to destabilise our planet, working together, we are powerful enough to save it.“In my lifetime, I’ve witnessed a terrible decline,” said the 95-year-old documentary maker, peering out at the crowd. “In yours, you could, and should, witness a wonderful recovery. That desperate hope — ladies and gentlemen, delegates, excellencies — is why the world is looking to you and why you are here.”
