Fire suppression in Europe has led to an overall decline in wildfire since the 80s, despite a global warming-fueled rise in risky fire weather. That can't last. "This is the kind of trend that is unstoppable." New in @nature.com:🧪 www.nature.com/articles/d41...

Fires in Europe are breaking records: here’s what the future holdsCountries such as Spain and France can expect fire regimes more like those of California as climate change favours hot, dry conditions, scientists suggest.www.nature.com

Quanta hitting it out of the park with this here cow

Quanta Magazine

Cows can eat up to 100lbs daily, thanks to the bustling microbiome in their gut pouch. All that digestion results in a whole lot of cow burps. And all those cow burps are warming our planet. Scientists are exploring new ways to squelch the belch. www.quantamagazine.org/a-new-way-th...

Latest inventory of pyrocumulonimbus events suggests that the past three years (2023-25) saw more fire clouds than any year back to 2013. But researchers told me record is still to short and sketchy to detect any trend, climate-related or otherwise.

But data on this pyroCb smoke remains sparse. With only a single sample of fresh smoke collected from the upper air. That leaves wider consequences of these clouds (which are likely to get more common with climate change) uncertain...

Enter INSPYRE. This massive NASA-led campaign is gearing up to fly through pyroCb exhaust to study the global consequences of these fire storms. @nature.com got an inside look at this mission taking off tomorrow in Colorado...🧪🌍 www.nature.com/articles/d41...

Firefighters in Oregon, Spain, and now France (?!) are battling wildfires big enough to generate pyrocumulonimbus clouds. These fire storms are treacherous on the ground. But scientists are concerned about the *planetary* consequences of injecting so much smoke into the upper atmosphere...🌍🔥🧵

It's not quite "gobsmackingly bananas" but monster forecasts for the record El Nino brewing the Pacific Ocean get pretty close. Here's what to make of it in my first for @nature.com: 🧪 www.nature.com/articles/d41...

This El Niño is set to be the largest on record by a ‘mind-blowing margin’Forecasters predict that the monster climate pattern will combine with global warming to push global temperatures in 2027 to new heights.www.nature.com

There's gold in them thar......subducted seamounts?? This is cool from @gernon.bsky.social etal. www.science.org/doi/full/10....

Hello friends. I'm starting a new job today reporting for @nature.com on all things climate and Earth science, energy, and beyond.🌍Please get in touch if you're a researcher/gov staffer/startup with results/projects that deserve attention--or are facing problems we should know about.

New type of intraplate volcano discovered on Atlantic seafloor? I took a look for @science.org at #goldschmidt 🧪⚒️ www.science.org/content/arti...

Thanks to the New York Public Library for the chance to talk about my research on the history of deep Earth geoscience. The library has been such a fantastic place to work. Can't beat the feeling of opening books that seem as though they haven't been read for a century. www.nypl.org/blog/2026/06...

Forty years ago this month the ecologist George Woodwell told the US Senate that warming feedbacks due to ecosystems emitting more GHGs were "at the edge of what science knows." For @yalee360.bsky.social I wrote about the climate scientists scrambling to catch up: e360.yale.edu/features/war...

Not that I would want to live on Mars, but I hear the aeolian geology is unparalleled.

The martian atmosphere is currently 200 times thinner than that of Earth. A 3 billion-year-old sandstorm recorded in the rocks could be the first direct evidence that wasn't always so. My latest for @science.org.🧪⚒️ 🚀🪐
