Dogs — an adored invasive species wreaking ecological havoc.
This story for New Scientist just kept unfolding. Dogs — feral, pet and all the shades in between — are hunting, terrifying, chasing, infecting and pooping their way round all but one continent. But we have a special bond with them — the answers are not simple.
This piece is not about the carbon footprints of pets — I deliberately leave that out. This is about biodiversity and ecosystems and what happens when you unleash a species into them that has an unfair advantage through continued human support. Read it here
This is such a great story which I barely scratched for this Nature piece. The multibillion dollar, almost-success story that is going wrong. A disease that has almost been wiped out but is now undermined by the very vaccine that brought success so close. The vaccine’s Achilles heel is that it mutates back to a virulent form and seeds polio outbreaks wherever there’s a weak spot — such as kids missed in a vaccination campaign or poor sanitation.
Then a new idea comes along and, with it, a race to “lock” the virus vaccine so it won’t transgress again. Several groups of scientists get together, each with a brilliant idea — and each idea was included in the final product. All done at warp speed (by pre-COVID standards). Read it here:
When pet cats roam free they kill a heartbreaking amount of wildlife — yet owners letting them out are just doing the best for the creatures they love. To find a way forward in the cat wars, I was really taken by the words of Wayne Linklater: “The solutions lie with the people who care most about cats, not with the people who don’t care about them.”
My New Scientist piece starts with lawyer Arie Trouwborst, who received death threats for his academic paper on the feasibility of prosecuting owners for allowing their felines to kill wildlife. More here:
Laudable goals to restore forests and other ecosystems are being twisted into a licence to plant trees anywhere — regardless of the damage this can cause to the environment and to livelihoods. In this long-read for SciDev.Net I look at the plight of grasslands, seen as “damaged” and therefore ripe for planting. The story begins in Madagascar.
Most surprising for me was that grasslands may actually be better than forests in some places at sequestering carbon, once you factor everything in. Second surprise was that trees planted in the wrong place can suck the water out of rivers with disastrous consequences for human communities. My third take-home was that the wrong trees can spread invasively and can be too flammable for the local climate. The resulting fires can kill (and they have done so). More here:
WEAVING through the sweaty tangles of a Panamanian forest, Steve Yanoviak is hunting a killer. Its prey isn’t the monkeys, bats or multicoloured birds that cram the branches, but the foundations of the forest itself – its trees. Each day, this killer strikes thousands of times around the world, but leaves no evidence behind. “Tropical trees die standing. They bear no scars,” says Yanoviak.
Catching it in the act takes monumental effort. That’s because the likely culprit isn’t a living organism, but instead a familiar force of nature: lightning. Read more:
I wrote a feature for Nature last year about the controversial scientist behind ambitious claims that planting a trillion more trees could help us out of the climate crisis. It’s been shortlisted as best specialist feature in the 2020 Association of British Science Writers awards. Results to be announced in October. Meanwhile you can find more on the article here
Firms are racing to create a real-time database of every object on Earth larger than a car. It would help investors and conservationists, but could it be abused? My piece for New Scientist is about Planet, which plans to create an interface through which users can ask questions about the entire planet. They call it “queryable Earth”. Think of it like a search engine not for the internet, but for the surface of our world.

“Thomas Crowther bursts barefoot from his office into the corridor, sweating through his faded T-shirt and grinning with exhilaration. It’s a warm July day and he has just finished telling NBC News that Earth could sustain another 1.2 trillion trees, which would absorb 200 gigatonnes of carbon, and that the next thing to do is to “stop talking and start planting” His claim comes from the latest in a string of high-profile ecology papers that have drawn the attention of the world’s media — and Crowther is loving it. Publicity, he believes, will get him closer to his goal, and his goal is nothing less than restoring the planet… more here
