China's Melting Glacier Brings Visitors, Adds to Climate Concerns

 

Each year, millions of people visit the 4,570-meter-high Baishui Glacier¹ in southern China. Scientists say it is one of the world’s fastest-melting glaciers².

The huge body of ice is in the southeastern edge of a Central Asian region called the Third Pole. It is about 4.5 million square kilometers in area and holds the world’s third largest collection of ice after Antarctica and Greenland.

Third Pole glaciers are critical to billions of people from Vietnam to Afghanistan. Seasonal³ glacier melts feed Asia’s 10 largest rivers, including the Yangtze, Yellow, Mekong, and Ganges.

Ashley Johnson is an energy, trade and economics⁴ expert at the National Bureau of Asian Research, based in the United States. She says the Third Pole is one of the world’s largest sources of fresh drinking water. She says an increase in melting from climate change may put that at risk.

Johnson said, “Depending on how it melts, a lot of the freshwater will be leaving the region for the ocean, which will have severe impacts on water and food security."

Earth is one degree Centigrade hotter than in pre-industrial times. The United Nations Intergovernmental Panel⁵ on Climate Change recently reported that that rise is enough to melt 28 to 44 percent of glaciers worldwide. And temperatures are expected to keep rising.

Baishui is about as close to the equator⁶ as Tampa, Florida. And the effects from climate change are already extreme.

A report this year in the Journal of Geophysical Research showed that the glacier has lost 60 percent of its mass. Since 1982, it has shrunk by 250 meters.

In 2015, scientists found that 82 percent of glaciers studied in China had decreased in size. They warned that the effects of glacier melting on water resources are becoming “increasingly serious” for China.

Jonna Nyman is an energy security expert at the University of Sheffield in England. She said, “China has always had a freshwater supply problem with 20 percent of the world’s population but only 7 percent of its freshwater.

“That’s heightened⁷ by the impact of climate change,” she added.

For years, scientists have observed global warming change Jade⁸ Dragon Snow Mountain in the Chinese province of Yunnan.

One research team has recorded Baishui’s decrease at about 27 meters per year over the last 10 years. Wang Shijin is a glacier expert and director of the Yulong Snow Mountain Glacial and Environmental Observation Research Station. The station is part of a group of stations run by the Chinese Academy of Sciences.

Wang notes that flowers have rooted and grow in the area once covered with ice.

The research station that houses Wang and his team is outside Lijiang, a city of about 1.2 million people. The team uses special equipment to collect data on temperature, wind speed and rainfall. Other devices measure water flow in streams fed by melted ice. Cold temperatures, heavy rain, falling rocks, strong winds and glacier movement can damage the equipment. One recent morning the team had to replace a broken weather research station.

However, the difficult weather conditions will ensure Yunnan has plenty of freshwater. In other areas, glacier loss creates serious risk of a dry period across the Third Pole, Wang said.

The next day, the team had to wear special ice climbing footwear while repairing other research devices on the glacier.

Wang spoke⁹ of how the area had changed.

He said, “Where we’re at right now was back in 2008 all covered with ice. From here to there at the side, the glacier shrank about 20 to 30 meters.”

The team crossed streams and jumped across deep, narrow divides in the glacier. They were looking for some measuring equipment they had placed in the ice earlier. The equipment shows how much the glacier has moved and the amount it dropped in height over the summer.

One team member launched a camera drone over the Third Pole. The images it captured help tell a story of extreme loss: 25 percent of its ice and four of its 19 glaciers have disappeared since 1957.

Wang said such changes to the Baishui glacier provide the chance to educate visitors about global warming.

Last year, Yulong Snow Mountain park officials reported that 2.6 million visitors came to the mountain.

On a recent windy day, hundreds of visitors climbed wooden stairs to take pictures in front of the glacier.

One visitor named Hou Yugang said he was not too concerned about climate change and Baishui’s melting.

“I don’t think about it now because it still has a long way to go,” he said.

To protect the glacier, officials have limited the number of visitors to 10,000 a day and have banned hiking on the ice. China plans to create snow there and block streams to increase the amount of water in the air, which slows melting.

Security guard Yang Shaofeng is a member of the local Naxi minority community. It considers Jade Dragon Snow Mountain to be sacred. Yang says he remembers being able to see the glacier’s lowest edge from his home village. But that time has passed.

“Only when we climb up can we see it,” he said sadly.
