Few people on Earth have reached closer to its center than Buzz Speyrer, a drilling engineer with a long career in oil and gas. It’s about 1,800 miles down to the core, smoldering from celestial impacts that date back billions of years and stoked to this day by friction and radioactivity. That heat percolating upwards turns the rock above into a viscous liquid and beyond that into a gelatinous state that geologists call plastic. It’s only within about 100 miles of the surface that rock becomes familiar and hard and…

Popocatepetl volcano spews incandescent material as seen from Paso de Cortés on May 23, 2023 in Amecameca, Mexico. Photo: Cristopher Rogel Blanquet (Getty Images)After a week of rumbling eruptions, Popocatépetl volcano is finally slowing down. The central Mexican volcano has been showing signs of activity, releasing smoke and a lot more since May 15. But the eruptions are finally stopping, and the volcano is emitting less ash this week, President Andrés Manuel López Obrador said during a Tuesday press conference,…

Add up the million or so buildings in New York City, and you get something on the order of 1.7 trillion pounds of weight pressing on the earth—and that’s not even counting all the other infrastructure, like roads and sidewalks. All that weight is deforming the ground, like bowling balls on a memory foam mattress, and causing a type of sinking known as subsidence, when land slowly compresses. New research finds that, on average, subsidence rates in NYC are between 1 and 2 millimeters per year, but in some places that’s up…

In the blink of an eye—at least in geological terms—life transformed from simple, soft-bodied creatures to complex multicellular organisms with shells and skeletons. …

because of the promising conditions in Starr and Hidalgo Counties, Jamie had been helping a handful of people there. The Sage team, of course. The public utility manager for the city of McAllen, who desperately wants to build a geothermal plant for his city. She’d been talking to Dario Guerra, a local water engineer who had been preaching the gospel of geothermal for years. One person she hadn’t met, though, was James McAllen.So, late in the afternoon, Jamie and I headed about an hour northwest from the city of McAllen to…

Climate scientists already know that the East Coast of the United States could see around a foot of sea-level rise by 2050, which will be catastrophic on its own. But they are just beginning to thoroughly measure a “hidden vulnerability” that will make matters far worse: The coastline is also sinking. It’s a phenomenon known as subsidence, and it’s poised to make the rising ocean all the more dangerous, both for people and coastal ecosystems.New research published in the journal Nature Communications finds that the…

Leaving the cultivated hillsides of the village, we crossed the park border and soon entered tropical forest, where jewel-like flowers peered out from under giant ferns and monkeys materialized and vanished as mist sieved through buttressed hardwoods. We trekked through bamboo forest, climbing to 12,800 feet (3,900 meters), where we entered the otherworldly Afro-Alpine moorlands, which contain endemic, endangered, and rare species.For two days we leapt from grassy tussocks to slippery tree roots, through bogs of spongy…
