Air pressure makes Mount Everest ‘shrink’ by thousands of feet, new study finds

Mount Everest is the tallest mountain in the world — but sometimes, it feels like the second-tallest, according to a story reported in the American Geophysical Union’s news blog Eos. That’s because the mountain’s air pressure fluctuates significantly throughout the year, a recent study found, causing the summit’s “perceived elevation” to occasionally dip below that […]

Mount Everest Can Sometimes Feel Lower Than K2

Like astronauts and master sommeliers, mountaineers who have summited Mount Everest eschewing supplemental oxygen are a rarefied group. Now, inspired by these individuals who push human physiology to its limits, researchers have analyzed the availability of oxygen on the world’s highest peak (8,848 meters). Weather-induced changes in air pressure alter the abundance of […]

Cold War-era satellites bring bad news about melting glaciers around Everest

At almost 29,000 feet, Mount Everest is the highest mountain in the World. The melting of its glaciers threatens the water availability for millions of people.

There are microplastics near the top of Mount Everest too — ScienceDaily

Researchers analyzing snow and stream samples from the National Geographic and Rolex Perpetual Planet Everest Expedition have found evidence of microplastic pollution on Mount Everest. While the highest concentrations of microplastics were around Base Camp where hikers and trekkers spend the most time, the team also found microplastics as high up as 8,440 meters above […]

Microplastics are showing up in places as remote as Mount Everest

Minuscule shreds and threads of plastic are turning up all over, including in the snow on Mount Everest. “We’ve known that plastic is in the deep sea, and now it’s on the tallest mountain on Earth,” says Imogen Napper, a marine scientist at the University of Plymouth in England and a National Geographic Explorer. “It’s […]
