Climbing Mount Everest is one of the difficult athletic feats a person can do . But new enquiry out this week intimate that it has gotten sluttish to pull off in recent years . The study found the success charge per unit of climbing the highest mountain on Earth has doubled in the last decade relative to age past , while the likelihood of demise has delay about the same , even as more people have attempt the journeying .
Lead author Raymond Huey , an evolutionary biologist and prof emeritus at the University of Washington , is no alpinist himself . But after hearing a speech from Reinhold Messner , a renowned social climber who in 1978 became one of the first to climb Mount Everest without supplementary O , Huey felt compelled to see if his own expertise could be applied to the account of mountaineer on Everest .
“ I wonder whether it was potential to apply analytical technique we practice in evolutionary biology and epidemiology to evaluate what was secure or bad on Himalayan peaks , ” Huey read .

For their subject area , Huey worked with statisticians Cody Carroll and Jane - Ling Wang as well as Richard Sainsbury , a Himalayan climber and sack out computing machine analyst . Sainsbury is one of the conscientious objector - laminitis of The Himalayan Database , an archival record of effort to mount Mount Everest and the hundreds of other Himalayan passel in or bordering the res publica of Nepal . Much of this history , dating from 1905 through Spring 2020 , was amass by Elizabeth Hawley , a diarist who died in 2018 at age 94 . Though Hawley ’s records were occasionally disputed , the mountaineering residential district at expectant had peachy admiration for her , and Nepal evennameda peck point after her in 2014 .
With these record , Huey and his squad analyzed the succeeder and death rate of first - time attempts up Everest during the years 2006 to 2019 , then equate it to a previous analysis cover the age 1990 to 2005 .
Over 2,200 mass attempt for the first time to make the superlative during the earlier time period , while more than 3,600 masses did the same between 2006 and 2019 . Between those two time periods , there was a decipherable improvement in how potential the great unwashed were to make it to the summit ( the degree of a good deal where there is nothing immediately higher than it in elevation ) .
“ The probability of reaching the summit and surviving has shoot up in recent decades : about 2/3 of crampon during 2006 to 2019 accomplish the summit and survived . But the probability of dying has remain fundamentally constant , about 1 % , ” said Huey . From 1990 to 2005 , the rate of success was around one - third .
The findings werepublishedin PLOS - ONE .
While most of the climber were man , the pct of women climbers has increased over time , with about 15 % of climber being women during 2006 to 2019 ; cleaning woman and military personnel had similar achiever rates . The per centum of older climbers also increase , with more than half being over 40 during late year . That said , erstwhile climbers did have a more or less high risk of dying than younger ace .
Though climb Everest remain a niche and severe hobby , the study ’s finding might provide some clarity on how to make the journey safer once climbing is allow again ( covid-19 led to the cancellation of the 2020 season ) .
For one , the study found no evidence that the crowding of climbers going up the mountain in a long line seen in recent years was associated with any heightened hazard of death or lower chance of succeeder , as some experts haveworried . But Huey mention that an untimely avalanche or snowstorm could still prove peculiarly life-threatening for climbers , and crowding does retard down climbing . As with other inquiry , they also find out no link between relative rawness on other Nepalese mountain and the success or death rates , maybe because climbers nowadays are taking advantage of commercial-grade expeditions more , which are ordinarily managed by experient mountaineers . Other factors for success belike include safe weather forecasting and the greater use of fixed ropes along the mountain that allow citizenry to stick attached and diminish their risk of falling .
For those uncoerced to make the arduous journeying , though , Huey still recommends that the great unwashed cut their teeth on something a little easier to start with .
“ If the destination is to increase one ’s chances of reaching the summit and also nonplus home live , then first testing oneself on a dispirited but still high peak will inform mortal how they respond physically and mentally to high elevation , ” he said . “ Also , being relatively young , perhaps 20 to 45 , help , although one 80 - year - old social climber did summit and outlast . ultimately , they must also be willing to climb in a farsighted railway line . ”
