Eleven people have died so far in 2019 while climbing Mount Everest, a behemoth of a mountain that towers 29, 029 feet above sea level. This is more than twice the number of people who died climbing Everest in 2018, which saw only five deaths that season.But it's not the number of deaths that some may find shocking — it's the reasons behind them. Only two of this season's Mount Everest deaths can be attributed to falls.So what's killing climbers ascending the mountain? It's primarily exhaustion and altitude sickness, and something called "the death zone."Seasoned climbers call any part of the mountain above 26,000 feet "the death zone" because there is only so long a human can survive at that elevation due to lack of oxygen. "Even when using bottled oxygen, supplemental oxygen, there's only a very few number of hours that we can actually survive up there before our bodies start to shut down," mountain guide Adrian Ballinger told CNN. And, unfortunately, the wait at the summit of Mount Everest plays a role in these deaths because the longer someone is at that altitude, the more severe they feel the effects from lack of oxygen and exhaustion. During the week beginning May 20, crowds of climbers became stuck in a queue to the summit. When this happens, climbers aren't eating, drinking or sleeping and continue to use up vital oxygen, which can lead to death.British climber Robin Haynes Fisher was one of those who had warned of the dangers of overcrowding."With a single route to the summit, delays caused by overcrowding could prove fatal so I am hopeful my decision to go for the 25th will mean fewer people. Unless of course everyone else plays the same waiting game," he wrote in a captioned Instagram post on May 19.He died after suffering from what appeared to be altitude sickness at 28,215 feet, while returning from the summit on Saturday.Altitude sickness occurs when people are at high elevations for an extended period of time. It can happen anywhere that's 8,000 feet above sea level or more. There are three types of altitude sickness. From least to most severe, they are: acute mountain sickness, high-altitude pulmonary edema (HAPE) and high-altitude cerebral edema (HACE). The symptoms for all three types are similar (headache, fatigue, dizziness, nausea, vomiting, shortness of breath), but HAPE is accompanied by a buildup of fluid in the lungs and HACE, the most severe type of altitude sickness, occurs when there's a buildup of fluid in the brain.So how can climbers avoid the same deadly fate as the 11 who died? Simply put — be careful. Acclimate as slowly as you can to increased elevations, drinks tons of water, rest and immediately start descending if you feel symptoms of altitude sickness.CNN contributed to this story. 2782

David Koch, a billionaire businessman and philanthropist who gained fame as an influential donor to conservative and Republican causes, is dead at 79.Koch Industries sent out a statement early Friday morning confirming his death.David Koch's brother, Charles Koch, who is chairman and CEO for Koch Industries, said the following:"It is with a heavy heart that I announce the passing of my brother David. Anyone who worked with David surely experienced his giant personality and passion for life. Twenty-seven years ago, David was diagnosed with advanced prostate cancer and given a grim prognosis of a few years to live. David liked to say that a combination of brilliant doctors, state-of-the-art medications and his own stubbornness kept the cancer at bay. We can all be grateful that it did, because he was able to touch so many more lives as a result."David Koch retired from the company and the Koch political operations in 2018, citing health reasons. The Koch brothers were best known -- and vilified by Democrats -- for their role in politics, and they used their vast wealth to build a sprawling array of think tanks, foundations and political groups to spread their small-government, free-market message. In some elections, the Koch network rivaled the spending and scope of the national Republican Party, and analysts view their activism as helping to have fueled the Tea Party movement.David Koch was most active in Americans for Prosperity, the grassroots arm of the Koch's sprawling network, which built a coalition of more than 3 million activists to push the agenda of the Kochs and the roughly 700 like-minded donors to help fund their public policy work.Their mission expanded to include large donations to colleges and universities as well as advocating for criminal justice reform. They also dedicated funds toward medical research and the arts.David Koch himself entered politics decades ago, waging an unsuccessful bid as the Libertarian Party's vice presidential nominee in 1980 with Ed Clark. They won just 1% of the vote.The Koch company is an industrial conglomerate that is one of the world's largest private companies, engaging in everything from oil refining to making consumer products such as Brawny paper towels. Forbes pegged David Koch's net worth at more than billion.Koch Industries has an estimated annual revenue of 0 billion and 120,000 employees. While primarily known as an oil company, it makes a wide variety of other products including Stainmaster carpet, Dixie paper cups and plates, Brawny paper towels and AngelSoft toilet paper, as well as fertilizer, asphalt and window glass.CNN Newsource contributed to this report. 2685

CINCINNATI — The Scripps National Spelling Bee is suspending the 2020 national finals in National Harbor, Maryland. The Bee recognizes the important responsibility to take action that protects the health and well-being of its participants including the spellers, their families, the local sponsors, employees of The E.W. Scripps Company and others who support the event known as Bee Week. The executive order from Maryland Governor Larry Hogan prohibiting gatherings of more than 50 people until the termination of the state of emergency in Maryland as well as recommendations from the Centers for Disease Control and Prevention underscore the decision to suspend the national finals.The suspension includes all in-person events and the live national broadcast the week of May 24. If possible, the Bee will work with local sponsors, spellers, convention partners and ESPN to reschedule the 93rd Scripps National Spelling Bee for later this year. The world is navigating through uncertainty, and while the timing of the national finals is just outside the eight-week window recommended by the CDC, this is the safest and most responsible action. This was a difficult decision that unfortunately will disappoint students who have spent a great deal of time studying and preparing, along with their parents and teachers who have supported them. The focus now shifts to exploring all options to possibly reimagine a competition for later this year.The Bee will keep local sponsors, spellers, parents and teachers informed in the coming days and weeks through direct emails, 1582
