Seismic surveys and sediment cores suggest that dozens of deep pockmarks on the sea floor were created when Arctic methane stores were disrupted by climate change after the last glacial maximum – and scientists warn it could happen again

A carbon removal trial that deposited olivine sand on a beach on Long Island did not find any heavy metal accumulation in marine life. But some scientists say absence of evidence may have been confused for evidence of absence. www.newscientist.com/article/2526...

<99% of trees' carbon can remain after they're killed by wildfire. But because these "widowmakers" can fall on people or livestock, landowners pile & burn them. Could burying them instead lock millions of tonnes of carbon away? www.newscientist.com/article/2526...

Record drought in US & England, drought & wildfires in south Europe, drought & conspiracies in Iran.. In response, governments are seeding clouds to make rain. But does it actually work? @newscientist.com deep-dive into history & future of this controversial tech www.newscientist.com/article/2524...

There are more and bigger wildfires in the Arctic as it warms - and these fires are not just burning the surface vegetation, but also carbon stores that built up in the soils over hundreds or thousands of years 🧪 #EGU26 www.newscientist.com/article/2526...

We knew methane hydrates can explode out of thawing permafrost. Turns out they can also be flushed out of grounding wedges by glacier melt. And USGS estimates methane hydrates hold 2x more carbon than all oil, gas & coal on Earth 😬 www.newscientist.com/article/2526...

A technique inspired by the film Interstellar suggests a new way of communicating backwards in time, but it could help improve conventional communication systems as well

Conservation projects issued 11x too many carbon credits for avoided deforestation. Conservation projects avoided deforestation. Both things can be true at the same time. www.newscientist.com/article/2525...

Psyched for the launch of the CNN Weather App, which I've been working on with a dream team of colleagues for months. It connects you with the experts & gives you a daily source of wonder. Here's the philosophy behind it: www.cnn.com/2026/05/12/w...

this graduation speech moment is notable, and her amazed shock at having failed to read the room feels instructive. when you're inside the bubble, you think everybody else is. but everybody isn't.

A bridge across the Bering Strait could stop the AMOC from collapsing. Minor caveat: "Because we don’t fully understand the AMOC, we can’t be sure of the consequences of such an intervention." www.newscientist.com/article/2525...

Where gas sets prices, prices are higher. r = 0.91 across European electricity markets in 2025. Italy & UK: gas sets prices 75-80% of hours, avg €90-115/MWh. Finland: 15% of hours, €42/MWh. More in my next Substack newsletter on whether renewables mean lower prices: janrosenow.substack.com

The UK has parachuted medics & oxygen into the world’s most remote island for a man who got hantavirus on the Hondius cruise ship. Not sure if I should feel reassured or more worried at the drastic measures being taken… www.theguardian.com/world/2026/m...

El Niño means “Emergency” for the Galápagos Islands! See that dark shade? That’s 20+ weeks of marine heat stress which NOAA says means “Near Complete Mortality” of shallow water coral, and threatens all the life associated, inc a life-threatening event for the Endangered Galapagos Penguins 1/

Terrifying, sickening and rage-inducing in equal measure. The Amazon could cross a tipping point as soon as 2031. Report by @alecluhn.com www.newscientist.com/article/2525...

We've lost 15% of the Amazon rainforest. If we lose >7% more, it could suffer mass dieback at >1.5°C warming, which we'll likely reach by 2030 www.newscientist.com/article/2525...

2026 is going to be the hottest year on record, exceeding 1.5C, James Hansen says. Not 2027. If he’s right, we’ll have to ask if global warming is accelerating even more than expected. www.newscientist.com/article/2525...

“The Turkish Mediterranean coast is the most polluted coast in the whole Mediterranean because of...plastic waste from the recycling factories. There’s huge amounts of microplastics–sometimes people can’t even get into the sea because of all the waste” ~ Prof Sedat Gündoğdu Photos, Verdat Örüç

While many think 2027 will be the hottest year ever, James Hansen says 2026 will be the hottest. That’s based on sea surface temperatures, which are even higher than a few years ago www.newscientist.com/article/2525...

With progress at COP climate meetings stalling, 57 countries took part in the first of a new series of conferences aiming to develop roadmaps away from fossil fuels, but big emitters like China and the US were absent

Europe, the fastest-warming continent, saw unprecedented wildfires and heatwaves in 2025, including a three-week hot spell that hit 30°C inside the Arctic circle

If vehicle-to-grid (V2G) charging was available in the US, an EV could make you <$3,359/yr selling energy to the grid when parked, a pilot project found. Nissan, VW, Tesla, BYD, Ford, etc are starting to offer V2G, but govs/utilities need to make buyback tariffs www.newscientist.com/article/2523...

So much for being politically homeless.

A planet-warming El Niño climate phase is now developing, and some models predict it could turn out to be the strongest on record

Measurements by buoys at four latitudes in the western Atlantic provide the strongest evidence yet that the Atlantic Meridional Overturning Circulation is weakening

Besides deep-freezing Europe & disrupting Asian & African monsoons, AMOC collapse due to global warming would also release hundreds of billions of tonnes of CO2, warming the globe even more www.newscientist.com/article/2522...

Peter Magyar has offered a template which can be used, without too much alteration, in defeating populists worldwide open.substack.com/pub/iandunt/...

Regret to inform everyone that Peter Magyar beat the world’s smartest illiberal populist in large measure by working incredibly hard for 2 straight years, meaning the rest of us are just going to have to get off our asses and do shit rather than just complaining.

This is a great read to start to put the puzzle pieces for building a new geopolitics. "The new world order will be defined by connectivity without hegemony. More possibility and more peril. This is the paradox that defines the new world order." 🎁🔗 www.bloomberg.com/news/article...

Even though we are left unscathed, the things that drivers do to cyclists are really unpleasant.

Models show the AMOC is weakening, but we didn't have long enough direct observations to be confident. Now moorings at four different latitudes in the western Atlantic have given the strongest evidence yet that the AMOC is slowing down www.newscientist.com/article/2522...

California is offering hundreds of millions in grants & credits to dairies that install digesters to capture biogas from manure. This reduces methane emissions. But it also makes cow shit as valuable as cow milk, which could have unintended consequences ... www.newscientist.com/article/2522...
