Scientists have been uncertain about whether Tibet has been rising over the last tens of millions of years or so.

(61:1.11) 40,000,000 years ago the land areas of the Northern Hemisphere began to elevate, and this was followed by new extensive land deposits and other terrestrial activities, including lava flows, warping, lake formation, and erosion. …
(61:1.13) Considerable foraminiferal limestone was deposited in European waters. Today this same stone is elevated to a height of 10,000 feet in the Alps, 16,000 feet in the Himalayas, and 20,000 feet in Tibet. The chalk deposits of this period are found along the coasts of Africa and Australia, on the west coast of South America, and about the West Indies.
(64:1.1) Primitive man made his evolutionary appearance on earth a little less than one million years ago, and he had a vigorous experience. He instinctively sought to escape the danger of mingling with the inferior simian tribes. But he could not migrate eastward because of the arid Tibetan land elevations, 30,000 feet above sea level; neither could he go south nor west because of the expanded Mediterranean Sea, which then extended eastward to the Indian Ocean; and as he went north, he encountered the advancing ice. But even when further migration was blocked by the ice, and though the dispersing tribes became increasingly hostile, the more intelligent groups never entertained the idea of going southward to live among their hairy tree-dwelling cousins of inferior intellect.
A May 2021 report out of the University of Copenhagen states:
There has long been controversy about whether the world’s highest region, Tibet, has grown taller during the recent geological past. New results from the University of Copenhagen indicate that the ‘Roof of the World’ appears to have risen by up to 600 meters and the answer was found in underwater lava. The knowledge sheds new light on Earth’s evolution.
Tibet is referred to as the Roof of the World for good reason. With an average altitude of 4,500 meters above sea level and the world’s two highest peaks, Mount Everest and K2, the vast Himalayan mountain range towers higher than anywhere else on Earth.
But the Tibetan plateau’s height has been the subject of academic controversy for many years. Some researchers believe that the area has been as high as it is today for most of its existence, while others believe that the area has increased in height over the past 20 — 30 million years. It is a riddle that until recently has stood and flickered unanswered in the wind. …
