The Chinese today admit that the warming on the Tibetan plateau will have consequences for the entire Asian continent. A question could be asked: who is responsible for this change of climate in the first place?
Who cut millions of hectares of forest for decades on the Roof of the World?
Where did the wood goes?
The answers are obvious, but it is now too late and the climate becomes warmer and nothing can stop the glaciers melting. Asia will pay for the greediness of the People's Republic of China. I presume it is the fate of the colonies to be looted, but in this case, China will also have a price to pay (at least environmentally and probably karmically).
Warming of plateau is 'threatening all Asia'

Due to global warming, glaciers on the Qinghai-Tibet Plateau are retreating extensively at a speed faster than in any other part of the world.
The Qinghai-Tibet Plateau, one of the most susceptible areas on the planet to global warming, is heating up at such an alarming rate that experts fear it will suffer environmental deterioration and water shortages that may threaten the entire continent.
"The Qinghai-Tibet Plateau is among the regions worst hit by global warming," said Qin Dahe, of the Chinese Academy of Sciences (CAS). "In turn, this will have a deleterious effect on the global climate and also the livelihood of Asian people."
Qin, who is the former head of the China Meteorological Administration (CMA), was the first Chinese person to cross the South Pole.
He pointed out that the temperature in the Tibet autonomous
Tibet's average temperature in July was the highest since 1951, according to CMA data.
And, during the same month, there was between 30 and 80 percent less rain in western and southern Tibet than in the same month in previous years.
"Due to global warming, glaciers on the Qinghai-Tibet Plateau are retreating extensively at a speed faster than in any other part of the world," Qin said. "In the short term, this will cause lakes to expand and bring floods and mudflows."
He said the climate changes will cause widespread problems across the
"In the long run, glaciers are vital lifelines for Asian rivers, including the Indus and the Ganges. Once they vanish, water supplies in those regions will be in peril."
Yao Tandong, one of China's leading glacier experts and director of the Qinghai-Tibet Plateau Research Institute of CAS, echoed Qin's view, adding that glaciers were accurate archives of climate changes.
"Glaciers on the plateau show warming has been abrupt and exceptional. It is warmer now than at any time during the past 2,000 years," Yao said.
The plateau is the world's third-largest store of ice. So far, 82 percent of glacier surfaces on the plateau have retreated and the glacier area itself has decreased by 4.5 percent during the past 20 years.
The Intergovernmental Panel on Climate Change (IPCC), a United Nations body studying global warming, predicted in May that Himalayan glaciers (including the Qinghai-Tibet Plateau) could vanish within three decades at the present rate of warming.
Another huge threat from warming is the degradation of the permafrost - the perennially frozen ground, Qin said.
"Permafrost plays a vital role in protecting the ecological environment and hydrological cycles. But it has been breaking down during the past 50 years," Qin said.
He pointed out that if vegetation on the plateau decreases, "consequent absorption of solar radiation will change the intensity of summer monsoons in Asia. This will bring drought to north India and intensify floods in southern China and droughts in the north".
He said construction in the area will also suffer.
"The Qinghai-Tibet railway and highway surfaces may possibly become deformed in the future," Qin warned.
But Cheng Guodong, a CAS researcher and member of the Qinghai-Tibet railway project team, was more optimistic.
"After we took measures to cool the permafrost under the railway, it hasn't melted during the past three years. I believe the railway will be safe over the next 50 years," he said.
And Qin pointed out there were also positives associated with warming on the plateau.
"Warming is good for agriculture and tourism. It has increased the growing season of crops," Qin said.
Scientists agree that the Himalayan
"The region is like an antenna and reacts quickly to global warming," said Andreas Schild, director general of the International Center for Integrated Mountain Development in Nepal, when speaking at the 5th International Symposium on the Qinghai-Tibet Plateau in Beijing last week.
"Warming will also evaporate more water into the stratosphere and thus accelerate warming, which will influence or even alter global climate," said Schild.
As the world's highest and most complex mountain range, the Himalayas stretch across six countries, including China, India and Nepal. Several major rivers in Asia, including the Yangtze, begin there, and their combined drainage basin is home to more than 2.7 billion people, Qin said.
Schild said Asian nations should make systematic efforts and boost regional cooperation and look for ways to slow warming, as well as find ways to adapt to it.
Warming has become "a cruel reality that many countries and regions in the world have to face, but it is not a problem that can be handled by one region or country alone", Qin said.
