Mount Everest glaciers shrink 28% in 40 years

New Delhi: As a result of climate change, the glaciers on Mount Everest, which are the birthplace of major Asian rivers such as the Ganga, Brahmaputra and Indus, have shrunk by 28 per cent in the past 40 years, according to a report.

The report released by Hunan University of Science and Technology, the Chinese Academy of Sciences (CAS), and Mount Qomolangma Snow Leopard Conservation Centre, made comparisons according to measurements taken in the 1970s.

The glacier area in the southern slope of Everest in Nepal has reduced by 26 per cent since 1980s, the report said.

Known as Mount Qomolangma in Tibet, Mt Everest has also been getting warmer for the past 50 years, added the report.

A researcher from the State Key Laboratory of Cryospheric Sciences under the CAS, Kang Shichang, informed that the report was compiled based on information collected by on-site monitoring and long-term remote sensing.

Covering 2,030 square kilometres, the national nature reserve of China’s Mt Qomolangma at present consists of 1,476 glaciers, as reported by the state-run Xinhua news agency.

Glacial lakes have been swelling, and river levels have been rising downstream, said Kang, who has led several teams for glacier inspection.

Kang added that a glacial lake in the Mt Everest nature reserve which earlier in 1990, covered an area of 100 square kilometres, swelled to occupy 114 square kilometres in 2013. This information was gathered via remote sensing data.

Earlier in May, a group of international researchers had warned that the in the– site of many of the world’s tallest peaks including Mount Everest – could reduce their volume by 70-99 per cent by 2100, with dire consequences for farming and hydropower generation downstream.

By 2100, the Hindu Kush –Himalayan (HKH) region—would possibly face a 70-99 per cent reduction in its estimated 5,500 glaciers, a group of international researchers warned in May. This will create disastrous effects in farming and hydropower generation in downstream areas.

Worsening extreme weather linked to climate change is creating hardships for many, from immediate deaths and injuries to increases in asthma and heat stroke. But the psychological trauma that often accompanies such losses is barely on the map.

Depression, anxiety, suicide and post-traumatic stress disorder tend to increase after floods, storms, wildfires and heat waves, according to the American Psychological Association (APA), which represents psychologists in the United States.

“The problem with that link is it’s not like so obvious. It’s not like I stick a needle in you, you feel pain right away,” said Anthony Ng, former head of the APA’s caucus on climate change and mental health.

“Some of this is so insidious and gradual that people won’t realize it until it’s too late. That’s why it’s hard for a lot of people to appreciate it.”

Panic

The debate over how to safeguard residents of picturesque Ellicott City, a tourist draw an hour’s drive north of Washington, D.C., illustrates the challenges many towns are facing as the world becomes warmer and wetter.

The town was devastated in 2016 by a so-called 1,000-year flood — meaning a magnitude with a one-in-1,000 chance of occurring in any year. The Patapsco River, which runs through the town, rose more than 13 feet in less than two hours.

Less than two years later, a 1,000-year storm struck again, overwhelming the tributaries that converge under the old mill town’s buildings and feed into the Patapsco.

Warmer temperatures are increasing heavy downpours, and rainfall has been growing in intensity in the Northeast, according to the government’s 2018 National Climate Assessment, risking power outages and the viability of roads and bridges.

As Ellicott City has become more built up, floodwater flows across paved roads and rooftops, instead of percolating down through the soil as it used to — a phenomenon known as urban runoff, which is worsening globally as cities grow.

In the wake of the 2018 floods, the county launched the Ellicott City Safe and Sound plan, which involves demolishing some old buildings, making tunnels to carry water under roads and clearing waterways more regularly.

Officials are also testing a flood warning system, with emergency sirens telling people to move to higher ground. It has caused some alarm among residents, said Amy Miller, a social worker at the Grassroots Crisis Intervention Center.

“You almost have a panic response,” said Miller, whose non-profit organization, based in Columbia, some 8 miles (13 km) south, has provided food, shelter and support to flood survivors.

“We’re basically exposing ourselves to the perceived threat of a traumatic event.”

Suicides

Grassroots provides 24-hour counseling to people in Ellicott City and the surrounding rolling hills of Howard County who might be feeling suicidal.

Miller has trained farmers to watch out for each other and spot signs of danger, particularly suicide risks.

Farmers are a high risk group. They tend to live solitary lives, have access to lethal means and face financial stress when hit by poor weather and low prices — factors they cannot control, according to anti-suicide campaigners.

“When your livelihood is impacted, that causes hopelessness,” Miller said. “The hard part for farmers is they work almost 24-7, and it’s really hard for them to seek treatment.”

Stanford University predicted last year that a hotter planet could lead to a surge in suicides by 2050. Its data analysis found suicides had risen 0.7% in the United States and 2.1% in Mexico with a 1°C increase in monthly average temperatures.

The researchers also found — by analyzing the language used in more than a half billion Twitter posts — depressive language increased during hot weather, suggesting worse mental health.

Keith Ohlinger, one of the Howard County farmers trained to keep an eye out, said he was driven to the work by the suicide of a young friend who grew up on a nearby farm, planned a career in agriculture and took her own life last year at age 21.

He struggled this spring with heavy rains washing away seeds and soil and leaving hay too wet to be dried and stored for winter feeding.

“Things are changing,” he said. “The Earth is changing, patterns are changing. Things are melting.”

Ohlinger uses his position on the Maryland Agricultural Commission, which advises the government on farming, and at monthly farmers club meetings to bring up mental health, often taboo in the conservative agricultural community.

He said climate change was just one more stress for farmers already worried about commodity prices, credit, bank loans, the price of equipment and old family-run farms being squeezed out by more and more giant residential homes known as McMansions.

“I can’t fix pricing. I can’t fix what the Chinese president or Donald Trump does, but I can surely try and keep someone from killing themselves,” Ohlinger said.

Not everyone in the region is willing to make the link between mental health problems and climate change.

Global warming as a manmade phenomenon is a politically divisive topic in the United States, where President Donald Trump announced plans to withdraw from the Paris agreement, a global pact to fight climate change.

“You talk about global warming, but we deal with this stuff all the time,” said another Howard County farmer, Howie Feago.

“Most farmers believe it’s more of an ebb and flow. We know that the weather is going to be up and down. If you’re going to worry about global warming, you probably ought to get some other kind of job because it will drive you nuts.” (VOA)
