The official height of Mount Everest has been the subject of intense negotiations between Nepal and China. The revised number both countries have agreed upon: 8,849 meters, or about 29,032 feet.

A Nepal government committee formed after a bad mountaineering season on Mount Everest has recommended new rules that would require climbers to have scaled tall peaks, undergone proper training, and possess certificates of good health and insurance that would cover rescue costs if required. A report by the committee released Wednesday, Aug. 15, says people must have successfully climbed a peak higher than 6,500 meters (21,320 feet) before they can apply for a permit to scale Mount Everest. Each climber would also be required to have a highly experienced guide. (AP Photo/Niranjan Shrestha, File)
