Sir David Attenborough has mastered the craft of storytelling. He has undoubtedly inspired generations of people around the globe to love and care for the natural world. And in doing so, he’s become one of the most recognisable – and most trusted – faces on our screens.

Now, he’s celebrating his 100th birthday and a lifetime of wildlife filmmaking. As part of The Conversation UK’s climate storytelling strand, four experts critique how he has influenced everything from conservation and documentary production to the communication of the biggest story of all – climate change.

Ben Garrod, science broadcaster and Professor of Evolutionary Biology and Science Engagement at the University of East Anglia, has presented alongside Attenborough in several landmark documentaries. Here he reflects on Attenborough’s passion for furthering our scientific understanding of the natural world.

I once sat on a remote beach with Attenborough, near the very tip of South America. I can still clearly remember the warmth of the rounded, flat stones beneath me. We sat only a metre or so apart. We’d just spent the morning filming the excavation of the largest dinosaur ever discovered.

Over lunch, Attenborough had recalled we were close to a beach he’d filmed at years before, where grey whale mothers drew in close to shore with their calves to rub against the stone in the shallows to exfoliate their skin. As luck would have it, it was the perfect time of year and before long, there we were watching a mother and calf just a few metres offshore.

Facts and figures bubbled out of Attenborough excitedly, not at all like the calm and more measured way we’re all so used to. For those few minutes, he was childlike in his wonder and excitement at the scene in front of us and I marvelled at how he has not only maintained that love for the natural world for so long but how he has always so passionately shared it with the rest of us.

For a century now, Attenborough’s life has been intimately interwoven not only with humanity’s growing scientific understanding of the natural world but also its accelerating loss. Spanning over 70 years, Attenborough has been our most trusted and prolific mediator between scientific knowledge and the public.

His early landmark BBC series Life on Earth: A Natural History (1979) did something few academic texts ever could. It made the complexity of evolutionary biology accessible. Across his work, natural selection, adaptation, ecology and behaviour are not presented as intangible concepts but as organic processes shaping form, function and ultimately survival across the natural world.

In doing so, Attenborough helped normalise evolutionary thinking for hundreds of millions of viewers worldwide, embedding complex scientific principles into popular culture, right in our living rooms.

Central to his work has been a commitment to scientific accuracy. Attenborough’s programmes have been developed in close collaboration with academics and field researchers, ensuring narratives about animal behaviour, ecosystems and biodiversity reflect current evidence.

This relationship between science and storytelling has been crucial because rather than dumbing down complexity, Attenborough’s “everyday” approach demonstrates audiences can engage with content that could all too easily be written off as belonging to more academic and scientifically literate viewers.

The Insights section is committed to high-quality longform journalism. Our editors work with academics from many different backgrounds who are tackling a wide range of societal and scientific challenges.

Yet the tone of his work has changed. His early documentaries were characterised by a sense of abundance and discovery. Over time, as scientific evidence for biodiversity loss and climate change mounted, his work shifted accordingly. More recently, his documentaries increasingly shine a light on human impact, habitat destruction and extinction risk. This evolution of change in his own tone mirrors the science itself, highlighting Attenborough’s credibility as a communicator willing to adjust his message as the evidence........
