HOW could we talk about David Attenborough’s best documentaries without featuring the photo perhaps most associated with the broadcaster, whose 100th birthday is on 8 May?

Life on Earth, the groundbreaking 1979 series containing that iconic gorilla sequence, pictured above, introduced a wider audience to the calm narration and stunning nature shots for which Attenborough is known today. His many documentaries would go on to move from the ocean depths to the lives of plants, and from the distant past to the fight against climate change.

Read on to discover which made the biggest impact on our staff, and which they deem worth watching today.

Life on Earth is special to me for so many reasons. There is that famous encounter with gorillas. It was also the first ambitious nature series of its kind – without its success, we might never have had the many great series that followed it. Then there’s the brilliant way Attenborough tells the story of deep time as he descends the Grand Canyon, and then back up again. There’s probably as much science here as in the rest of his programmes put together – I don’t think I’ve seen a better TV series on the evolution of life. OK, from today’s perspective it is a bit lectury at times, but who would you rather be lectured by?

Last but not least, for me, it has personal meaning, as I’m sure it does for many other people who saw it in their youth and were influenced by it. That wonky opening music by Edward Williams is just so evocative.

Plants live on another plane of existence. Every morning, drooping wood anemones lift their heads and nod at the sun, while brambles grapple across the forest floor with slow aggression. Exploding pods launch seeds in a millisecond; on mountain tops, bristlecone pines gnarl into stumps over thousands of years.

Time-lapse and high-speed photography weren’t new when The Private Life of Plants was filmed, but this was the first series to use them at scale. They allowed Attenborough to explore the agency and the intelligence of flora like never before.

When I rewatch the series today, the lurid colour grade, bespoke plant-themed typeface and rudimentary CGI bring me as much joy as the plants’ private lives. I would also recommend the behind-the-scenes for the plants of Life, which lays bare the painstaking ingenuity of the film-makers who capture these other worlds.

The Pacific Ocean, seen from the International Space Station
NASA

As the first in-depth look at what is happening beneath the rarely explored waves, The Blue Planet astounded me when I first watched it. New species were discovered and extraordinary footage showed blue whales from the air, alien-looking creatures in the ocean depths and, most surprisingly, herring sperm as far as the eye could see.

I am still haunted 25 years later by watching a pod of orcas spend 6 hours hunting a grey whale calf to eat only its lower jaw and tongue. Attenborough’s narration is calm, clear and concise, unafraid to let the images and music hold our attention.

It may not have the glossy HD footage or drone shots of more recent series, but it changed the shape of nature documentaries.

It also blew my mind and sparked a life-long interest in the oceans. Without it, I wouldn’t have ended up at żìĂš¶ÌÊÓÆ”!

Those nighttime images of a massive pride of lions swarming over a fleeing young elephant have stayed with me ever since the first series was shown in 2006. The film-makers set out to create a spectacular, high-definition series, and boy did they achieve it.

The many notable moments in Planet Earth include a starving polar bear trying to catch walruses, eagles preying on cranes as they fly over the Himalayas, dolphins beaching themselves to hunt fish and bears climbing mountains to feast on moths. This is simply incredible television. Watch it now if you haven’t seen it. Watch it again if you have.

The second series, first shown in 2016, also made a notable departure. While Attenborough’s previous series all showed wildlife in pristine wildernesses, the last episode here, and in the third series (2023), is about animals living alongside people, from leopards and monkeys to falcons and otters.

I do think Attenborough has been right to aim to evoke wonder rather than despair in most of his programmes, but now there’s no denying we live on a much-changed planet.

Polar bears in Frozen Planet
BBC

Wondrous and strange is the life that thrives at the very ends of Earth. Frozen Planet cast a loving eye over the inhabitants of the Arctic and Antarctica, hostile lands whose charms are apparent from the earliest moments of this excellent series. The narrative bounces back and forth from one pole to the other, treating us to scheming penguins, swimming snails, polar bears and a bison charging down wolves.

Among it all, the then 84-year-old David Attenborough, bundled up in a fetching array of parkas, makes the odd appearance as our all-terrain guide to these alien environments.

Casting a pall over proceedings, of course, were the advancing effects of climate change. The series’ seventh episode, “On Thin Ice”, was an explicit call for the world to do more to protect these magnificent ecosystems and those living in them, including humans.

The magic of Frozen Planet wasn’t just that it told us how global warming imperils the poles, it’s that it made us truly care about what we might be losing.

A turtle swims over a coral reef in A Life on Our Planet
Netflix / David Attenborough: A Life On Our Planet

Like an ice core or tree ring, David Attenborough’s long and extraordinary life has come to be used as a yardstick for change. Socially, technologically and environmentally, the world of his youth was a far cry from the one we see today – and in this powerful film, Attenborough charts how we have degraded Earth’s ecosystems over his lifetime.

Released during the first year of the covid-19 pandemic, A Life on Our Planet was a timely warning from a man who has seen more of Earth’s wonders – like this turtle, pictured swimming over a coral reef – than perhaps anyone else alive. Its marriage of the personal and the political makes it a different beast from most Attenborough films. Climate change, biodiversity loss and rampant pollution all feature, as Attenborough sets out what a child born in 2020 may witness over their lifetime. It makes for bleak viewing, but, as is a hallmark of more recent Attenborough works, it also supplies plenty of solutions to the environmental crises we’re living through – if we’d only apply them.

Rapetosaurus, a long-necked sauropod from Madagascar, in Prehistoric Planet
Apple TV

Prehistoric Planet is far from the first programme to try to bring long-extinct animals back to life on the small screen, but it is the best so far. Of course, the programme-makers had to use their imagination to some extent, but the series has been praised by palaeontologists for its accuracy and naturalism.

The three series feature many of the most iconic animals of the past, but shows them in new ways – we see Tyrannosaurus rex swimming and mating, for instance. There are lots of smaller, lesser-known animals, too. For me, the real stars are not the dinosaurs but the pterosaurs, brought back to life in stunning detail.

The third series jumps forward in time to the recent glacial periods, featuring animals such as mammoths, sabre-toothed cats and many more. The content is just as brilliant, but Tom Hiddleston replaces David Attenborough as the narrator. It’s just not the same without him.

This very late entry to the David Attenborough canon became an instant classic in my household, since it was shown on New Year’s Day. We’ve rewatched the extraordinary exploits of London’s wildlife many times.

Yes, this one-off urban showcase has the foxes and pigeons you would expect, but not as you would expect to see them: vixens viciously squaring off on the streets of Tottenham and pigeons intelligently commuting on the tube from Hammersmith are standout moments.

But the bigger surprises come from how much the city’s nature has changed in recent decades. Peregrine falcons now soar over the centre, ring-necked parakeets have conquered the parks, Aesculapian snakes dangle from the trees along the Regent’s Canal and, since covid lockdowns, large numbers of fallow deer have taken to roaming parts of Romford.

The programme tours a London that is familiar to locals but rarely seen on screen: the community gardens, cemeteries and suburban parks that make the city an outstanding place to live, even for the nature-lovers who sometimes wonder if a megacity is the right place for them.

Perhaps their lingering doubt will be extinguished by Attenborough’s own assertion that he wouldn’t want to live anywhere else.

Alkaline sodium hydroxide was dumped into the Gulf of Maine to test its effect on carbon uptake and marine life

Can we safely remove carbon dioxide from the atmosphere by counteracting ocean acidification? Maybe, suggests a trial in which ships poured 65,000 litres of alkaline sodium hydroxide into the Gulf of Maine off the East Coast of the US in August 2025. “We’re the first group to do a ship-based alkalinity enhancement experiment,” says at the Woods Hole Oceanographic Institution in Massachusetts, whose team announced their initial findings at the in Glasgow, UK, on 25 February. “We can definitely say that there was additional CO2 uptake as a result of this experiment.” Between 2 and 10 tonnes of CO2 was removed from the atmosphere in the following four days, Subhas says, and the team estimates that up to 50 tonnes could be removed altogether. What’s more, no significant effect on marine life was seen. However, when asked by żìĂš¶ÌÊÓÆ”, Subhas acknowledged that the team has yet to estimate the emissions required to manufacture the sodium hydroxide and transport it to the trial site. This means it is unclear whether the trial resulted in a net removal of CO2. “It’s a really good question,” said Subhas. “That’s going to be a really critical area of research moving forward.” The oceans store 40 times as much carbon as the atmosphere and have soaked up more than a quarter of the excess CO2 we have been pumping into the atmosphere. This extra CO2 reacts with water to form carbonic acid, meaning that the oceans are becoming more acidic.
Ocean acidification could have a major impact on many marine organisms, for instance, by dissolving their carbonate shells. It also reduces the ability of the seas to take up more CO2. Researchers are exploring a number of methods to counteract ocean acidification, including adding magnesium hydroxide to wastewater that goes into the ocean, adding ground-up olivine to coasts and pumping seawater through land-based treatment plants. Some companies are already selling carbon credits based on alkalinity enhancement. “This is something that the private sector is moving forward with right now,” says Subhas, which is why there is a need for non-commercial trials like the one his team did. Because of the controversial nature of these kinds of trials, the team started by engaging with local people, particularly in the fishing community, says team member of the Environmental Defense Fund, a non-profit organisation based in New York. “Two-way dialogue is really critical,” she says. The trial itself involved three ships and was monitored in several different ways, ranging from satellites to floating sensors to ocean gliders that zigzag up and down. The sodium hydroxide was mixed with trace quantities of a dye called rhodamine, to help accurately track its dispersal. The team measured the concentrations of microbes, plankton, fish larvae and lobster larvae, and also the level of photosynthetic activity, says at Rutgers University in New Jersey. “There was no significant impact of our field trial on the biological community,” she says. The extra carbon taken up by the ocean as a result of the increased alkalinity is turned into bicarbonate ions, or dissolved baking soda, Subhas says. “We expect that this carbon is locked away for tens of thousands of years. It’s one of the most durable forms of carbon removal.” The nature of the process means that CO2 is removed and stored in a single step, Subhas says. This is an advantage over some other approaches, where CO2 is first removed from the atmosphere and then has to be permanently stored in some form.]]>

An experiment on oxygen production by deep-sea nodules
The Nippon Foundation

żìĂš¶ÌÊÓÆ”s will lower instruments to the seafloor to figure out how metallic nodules are generating oxygen in the depths of the Pacific Ocean, an unexpected phenomenon that has fuelled controversy over deep-sea mining.

Researchers, to their surprise, found in 2024 that the potato-sized nodules in the darkness of the Pacific and Indian oceans, including the Pacific’s Clarion-Clipperton Zone, were a source of oxygen, even though it was thought that sunlight and photosynthesis were needed to produce this element on a large scale.

This so-called dark oxygen could be supporting life in the darkness at depths of thousands of metres, including microbes, sea cucumbers and carnivorous anemones. Its discovery raised questions about proposals by deep-sea mining companies to vacuum up the nodules from the seafloor and smelt them for cobalt, nickel and manganese. The finding has been by deep-sea mining companies, and other scientists have also called for more evidence.

Now the researchers who discovered dark oxygen are going back to the Clarion-Clipperton Zone, the most promising area for deep-sea mining, to try to confirm the existence of this dark oxygen and understand how it is being produced.

“Where’s the oxygen coming from for these diverse animal communities to thrive?” at the Scottish Association for Marine Science, who is leading the expedition, said at a press briefing. “This may be a pretty significant process, and that’s what we’re trying to figure out.”

The team has hypothesised that the layers of metals in the nodules are generating an electric current that can break down seawater into hydrogen and oxygen. They have measured up to 0.95 volts of electricity on the surface of nodules, slightly less than an AA battery.

That’s less than the 1.23 volts that would typically be required for this electrolysis, but the researchers think some individual nodules or several nodules grouped together could generate higher voltages.

The team will deploy landers – essentially metal frames with instruments inside – to depths of up to 10,000 metres to measure oxygen fluxes as well as pH, since electrolysis would cast out protons that increase the acidity of the water.

The landers will also obtain sediment cores and nodules to analyse later in the lab, since microscopic organisms may also play a role. Each nodule contains up to 100 million microbes, and the researchers will try to identify microbes through DNA and RNA sequencing and fluorescence microscopy.

“The vast diversity of the microbes remains a moving target. We’re always discovering new species,” said team member at Boston University. “Are they active? Are they shaping their environment in interesting and important ways?”

They will also recreate the conditions of the deep sea in a high-pressure reactor and run the electrolysis reaction in it, since electrolysis hasn’t typically been seen at the intense pressures found on the seafloor.

“Four hundred atmospheres of pressure, that is the pressure at which the Titan submersible imploded,” said at Northwestern University in Illinois, another team member. “We’re interested to see how water splitting may or may not be effective at high pressure.”

The ultimate goal is to try to run the electrochemical reaction under an electron microscope with microbes and bacteria present, all without killing the microscopic organisms, he added.

While the United Nations’ International Seabed Authority hasn’t made a decision on whether deep-sea mining should be allowed in international waters, US President Donald Trump has pushed for extraction to start. The Canadian firm The Metals Company has applied to the US government for a permit to begin deep-sea mining.

A published by scientists from The Metals Company argued that Sweetman and his colleagues did not find enough energy to power seawater electrolysis in 2024 and that the oxygen they observed was likely carried from the surface by the landers they deployed.

Sweetman says any bubbles of surface air are washed out as the landers descend, and they haven’t measured oxygen when deployed in other areas of the ocean, such as the seabed in the Arctic, at 4000 metres. Of 65 experiments done in the Clarion-Clipperton Zone, 10 per cent have found oxygen consumption and the rest have found oxygen production, according to Sweetman.

He and his colleagues have also found that the water oxidation part of the electrolysis process can take place at the lower voltage found on the nodules. A rebuttal including this data has been submitted to Nature Geosciences and is currently going through peer review.

“In terms of the commercial interest, there’s definitely an interest to try to silence this area of work,” Sweetman said of The Metals Company’s objections to his findings.

“Regardless of the source and motivation of the comments, they need to be addressed,” said Marlow. “That’s what we’re in [the] process of doing.”
