The world's highest peak just grew a couple of feet overnight — on paper, at least.
On Tuesday, after years of fraught discussion and surveying work, China and Nepal announced a revision to the elevation of Mount Everest: Officials say the summit now stands precisely at 8,848.86 meters, or 29,031.69 feet above sea level.
That makes the official measurement more than 2 feet taller than the consensus had it on Monday.
