Mount Everest was once a pristine environment. However, due to increased tourism, waste is accumulating on the mountain, with large proportion being made of plastic. This research aimed identify and characterize microplastic (MP) pollution near top highest mountain Earth could illustrate implications for environment people living below. Stream water snow were collected from multiple locations leading up to, including, Balcony (8,440 m.a.s.l). MPs detected at an ~30 MP L−1 in ~1 stream water,...
Abstract As the highest mountain on Earth, Mount Everest is an iconic peak that offers unrivalled natural platform for measuring ongoing climate change across full elevation range of Asia’s water towers. However, Everest’s extreme environment challenges data collection, particularly mountain’s upper slopes, where glaciers accumulate mass and mountaineers are most exposed. Weather stations have operated before, including world’s previous highest, but coverage has been sparse in space time....
Records from new high altitude weather stations reveal the meteorological conditions on Mt Everest during 2019 monsoon. Using data June–October, we show that temperature, humidity and winds announce arrival of monsoon, with changes amplify elevation. The largest change is therefore at summit, where estimate monthly mean air temperature increased by 5.5°C between June July to average −19.1°C over Such warming takes temperatures into realm winter much lower mountains mid-latitudes, illustrated...
Cumulative environmental effects from the offshore oil and gas industry in Canada are inadequately addressed Environmental Assessment process due to complexity of analysis required overcome unknowns with respect environments. Limited Assessments can lead deleterious consequences for wildlife populations their habitats dependent on marine ecosystems, particularly as adverse become additive synergistic. A Strategic generates guiding policies programmes future industrial activities, while...
This case study provides a framework for future monitoring and evidence human source pollution in the Khumbu region, Nepal. We analyzed chemical composition (major ions, major/trace elements, black carbon, stable water isotopes) of pre-monsoon stream (4300–5250 m) snow (5200–6665 samples collected from Mt. Everest, Lobuche, Imja Valley during 2019 season, addition to shallow ice core recovered Glacier (5300 m). In agreement with previous work, aerosol deposition is dominated by dust...
Species composition in high-alpine ecosystems is a useful indicator for monitoring climatic and environmental changes at the upper limits of habitable environments. We used DNA (eDNA) analysis to document breadth biodiversity present on Earth's highest mountain, Mt. Everest (8,849 m a.s.l.) Nepal's Khumbu region. In April-May 2019, we collected eDNA from ten ponds streams between 4,500 5,500 m. Using multiple sequencing bioinformatic approaches, identified taxa 36 phyla 187 potential orders...
The Everest region is characterized by its alpine glacial environment. In an effort to understand environmental change and tectonic activity, our team cored Taboche Lake, situated at 4,712 m along the western margin of Ngozumpa Glacier. This research catalogs past earthquakes using geological records lake core that are important for assessment future earthquake hazards in provides information risk floods. Core grain size characteristics internal sedimentary structures from computed...

In April and May 2019, National Geographic Rolex's Perpetual Planet Expedition to Mt Everest (hereafter 2019 Expedition) undertook most comprehensive science expedition (Mt Everest) included teams of scientists investigating a range topics, including glacier change, upward shifts ecosystems, black carbon deposition on surfaces snow/ice/water chemistry (Mayewski et al.,...
The Mount Everest region is characterized by its alpine glacial environment. In an effort to understand environmental change in the area, our team cored Taboche Lake, situated at 4,712 m along western margin of lateral moraine Ngozumpa Glacier. This research catalogues past earthquakes using geological records lake core that are important for assessment future earthquake hazards region. To achieve aims study, grain size characteristics and internal sedimentary structures from CT scan...
