The case against data centres is growing
The energy Gods giveth: the world (excluding China) added 124 gigawatts (GW) of solar power to global capacity in 2025. And the energy Gods taketh away: 100GW of new data centres are planned between 2026 and 2030...
Return of the beaver
As I glance down, the water is perilously close to spilling over the top of my wellies. But, despite it being late January and the water freezing cold, I push on. This is something I’ve waited a long time to see...
Forget heat pumps—this is how to heat our homes
I write from a garden office looking back at my Victorian mid-terrace house. At this time of year, that means I’m often cold—in fact I am currently looking through glass cross-hatched by ice crystals. I’m often struck by the fact that my home would have been warmer for the Victorians...
It’s time for COP’s next chapter
It didn’t bode well for Belém. Bill Gates undermined the UN climate conference, held in a city that is the gateway to the lower Amazon, with a Trump-appeasing essay before it had even begun. Swedish scientist Johan Rockström suggested delegates be “honest with the world and… declare failure” on Paris...
Scientists want to block out the sun. How worried should we be?
Ricken Patel comes to geoengineering with a heavy heart. The former president and CEO of global activism network Avaaz was recently praised for his “enormous contribution to the Paris Agreement” by Christiana Figueres, who led the Paris negotiations. Neither the Patel nor Figueres of 2015 would have contemplated geoengineering...
The great 2025 solar boom
In 1978 President Jimmy Carter gave a speech praising a new National Solar Energy Research Institute, and extolling the sun’s “inexhaustible sources of energy. No cartel controls the sun.” He even installed 32 solar panels on the White House roof...
Why the ‘Paris Agreement’ of plastics ended in failure
I was on a beach when the latest global plastics treaty came and went in ignominy. At a remote spot on the South American Pacific coast, where all supplies and materials must come by small boat, and the locals make use of everything...
‘This feels like time travel’: has the ‘regen’ revolution begun?
When Andy Cato first got the call from Jeremy Clarkson, he thought he was just going to Diddly Squat for a cup of tea. As he arrived, the cameras for Clarkson’s Farm series 3 were rolling...
On climate, perfect is the enemy of good
The phrase “perfect is the enemy of good” (from Voltaire’s 1770 Questions sur l'Encyclopédie, in case you wondered) is a truism in climate action, if not in everything. We are fast approaching this year’s Earth Overshoot Day...
Economic growth and the search for abundance
A moment halfway through Ezra Klein’s and Derek Thompson’s recent book Abundance reveals something of their approach to building a net zero world. In 2023 a gasoline lorry exploded, causing Philadelphia’s I-95 bridge to collapse; Governor Josh Shapiro waived all the usual rules and regulations for public works so it could be rebuilt in record time. The project was of great benefit to the community. But during the works, the state secretary of transportation recalls encountering two workers using...
Don’t drain the swamp—refill it
As I walk across the newly pedestrianised Hammersmith bridge, London is as it should be—grey and rainy. Ordinarily, getting drenched on the way to an interview might be annoying. But today it couldn’t be more apt...
Why isn’t it raining?
When I was first asked to write this column, among the editor’s requests were that I serve as “a guide through the climate crisis”. To do so, I tend to look for solutions, be they nature-based or policy, seek out experts or dig through scientific reports. But sometimes you only need to look out the window...
The Benefits of Letting your Lawn Go Wild
I’ve always liked mowing the lawn. Perhaps it’s a childhood nostalgia thing, having watched my dad do it seemingly every weekend in summer. The smell, the neat intermittent stripes, the angry roar as the mower...
In Britain, we burn precious peatland for sport
“To keep this moor viable we have to raise 6,000 grouse a season, which we do by killing everything else that moves,” says Viscount Deveroux, the alter-ego of comedian Henry Morris. Walking a moor, dressed in tweed and with 12-gauge shotgun...
Copenhagen’s disastrous ski slope-incinerator
Just beyond the end of Nyhavn, Copenhagen’s colourful canal district, an ominously smoking chimney punctures the horizon between sailboat masts and a cyclists’ bridge. Most tourists in town for one day wouldn’t go much further...
To fight flooding, bring back the beaver—for good, this time
I thought I might cry. But the emotions that threatened to overwhelm turned more euphoric—a silly, wide smile, plastered across my face for hours. As the first beaver padded tentatively but fixedly out of its cage towards the water, I was witnessing history. The first of its kind to return to this part of central England for over 400 years...
The best science books of 2024
Books contemplating the human experience and some of humankind’s greatest challenges were among the Science News staff’s favorite reads this year.
We Need To Talk About Degrowth: Part II
“It seems to be easier for us today to imagine the deterioration of the earth and of nature than the breakdown of late capitalism; perhaps that is due to some weakness in our imagination.” ― Fredric Jameson, The Seeds of Time (1994)
We Need To Talk About Degrowth: Part I
“Is the Earth’s balance, for which no-growth — or even degrowth — of material production is a necessary condition, compatible with the survival of the capitalist system?” — André Gorz, social philosopher, 1972
Exposing the Waste-To-Energy Lie
Waste-to-energy incinerators are touted as ‘renewable’, attracting private investors and public subsidies. But is it all smoke and mirrors?
Book review: The Times Literary Supplement
Today’s water scarcity is only partly due to climate change, the journalist Tim Smedley explains in The Last Drop. The major culprits are humans, who, the
Water companies make us look like April fools
I’m writing this on 1st April. My eldest daughter has taped over the light switch in the kitchen. My youngest put pepper in my tea. One of them has drawn on the toilet roll. And my water bill went up by 31 per cent overnight...
Climate activism after Just Stop Oil
Rupert Read, who helped launch Extinction Rebellion (XR), has long had doubts about the tactics of climate activists. He pauses halfway through our Zoom call with Caroline Lucas, former Green MP, to reminisce about the early days of XR...
