A 5 year long research report shows that before the advent of the next century, Himalaya and the Hindu Kush region (HKH) of the ice melt will be 1/3.
Has been hailed as the world's "third pole", the HKH area encompasses the towering Mount Qomolangma and K2, is the third-largest freezer on earth is located, 10 is also a source of important rivers, around the formation of a strong global ecological buffer area.
The International Centre for Integrated Mountain Development (ICIMOD) forecast report released, even in the most optimistic scenario, that global warming was successfully put forward at the Paris climate agreement within 1.5 degrees, three of the melting of the ice can not be avoided.
The more extreme weather conditions, the glaciers in 2/3 may disappear, overall ice loss will be as high as 90%.
ICIMOD deputy director general Eklabya Sharma told the Reuters, HKH ice if all melted, it would cause sea levels to rise 1.5 meters.
Because of the influence of sea level rise is more intuitive, the islands in the discussions on climate change in polar or high frequency is often mentioned, in fact covers more of the population, Himalaya stretches 3500 kilometers of mountain area is less attention by the outside world.
"This is the people do not have to understand the climate crisis." Project leader Philippus Wester said.
Formed about 70 million years ago the Himalaya glacier is very sensitive to temperature changes, since 1970s, they have become thin, shrinks, snow and snow covered areas have reduced.

Glacial thaw will disrupt the Mekong River, including the Yangtze River, India River and the Yellow River River, Pakistan, India, Chinese effect of about 1 billion 900 million people, drinking water, irrigation and energy demand. A large number of melting glaciers will bring floods, landslides and deadly pandemic threat.
The most direct impact is living in mountainous area population of 240 million, of which 70% are farmers, their way of life to be substituted, so deeply troubled by climate change.
"For Apple or grain on the steep slopes of farmers, which means they must promote the orchard to higher the uphill, chasing the cool climate required plants; in others, changing weather patterns make once reliable streams and springs due to the catastrophic flood threat." "National Geographic" analysis.
Himalaya mountain area itself has long suffered from poverty, relocation, child malnutrition, social discrimination and other structural problems, 1/3 of people living on less than $1.9 per day, the unstable factors of climate change will make the current plight worse.
At the same time, ICIMOD said, "third pole" area of warming rate was significantly higher than the global average, and in the high altitude area warming rate higher. Climate change projections indicate that by the end of this century, all of South Asia are likely to rise at least 1 degrees C, and in some areas, even the temperature could be as high as 3.5 to 4 DEG C.
More than 200 scientists will report, and 125 expert peer review. This report is not only the hope severity alert countries on climate change, trying to make more significant changes to the inevitable area, prepared to deal with and prevent the preparation, while encouraging cross-border cooperation between the leaders of the region, to find a way to stop the potential damage to climate change.
"Big tank glaciers and snow like water." Michele Koppes, a climate scientist at the University of British Columbia, said. The water for decades or even hundreds of years of slow release, but climate change forced melting occurs faster than ever, this is "draining their piggy bank", have a long-term effect on the entire ecological system.
