A new study by scientists at Loughborough University predicts a gradual decrease in the highest point on our planet. Due to climatic changes, Mount Everest is gradually shrinking and getting smaller. The scientists link the impact of air pressure on the mountain. Everest, or Chomolungma, is the highest mountain on our planet. But soon it risks losing this status.
The mountain is shrinking due to the fact that the air pressure in the rock is in a state of fluctuations, and it changes throughout the year. Because of that, the height of the mountain becomes less, and there are fixed rates when it is lower than its taller rival K2.
Climatologist Tom Matthews confirmed that sometimes K2 is higher than Chomolungma. It is confirmed by data from meteorological stations installed at the top of the mountain, as well as information received from the Copernicus satellite of the European Space Agency. Pressure is inextricably linked to the availability of oxygen at the highest point on the planet. According to the scientists, when the pressure drops, there is less oxygen.
People notice this by the difficulty in breathing. This is one of the reasons tourists who climb Mount Everest take oxygen cylinders with them. The higher up the mountain - the lower the pressure becomes, and it is also a confirmed fact, which, as it turned out, depends on weather phenomena.
Between 1979 and 2019, there was constant atmospheric pressure near the summit of Everest. It fluctuated between 309-343 hectopascals, which is about one third of the sea level pressure depending on the season.
Compared to the average air pressure that was measured on Everest, this gap is equal to 737 meters of difference in altitude according to the feeling of lack of oxygen. The most constant air pressure on Everest is considered in the summer. It is the best time to climb the summit.
But since the climate of our planet continues to change, and the air temperature is constantly increasing, this impact will affect Everest as well, it will shrink and become lower.
