Experts warn that climate change is speeding up melting on Earth’s frozen peaks, threatening the planet’s long-term water supply.

The more than 150 global mountain experts attending the first High Mountain Summit warn time is running out for the world’s glaciers. They say climate change is causing temperatures to rise in Earth’s frozen zones, leading to a rapid melting on vital peaks.


For example, scientists say Swiss glaciers have lost 10 percent of their volume in the past five years. The disappearance of hundreds of small glaciers in the Alps was dramatized when hundreds of mourners recently attended what was dubbed a “funeral” to mark the loss of Switzerland’s Pizol glacier.

The World Meteorological Organization reports international observers show an acceleration in the retreat of 31 major glaciers in the past two decades. They include mountains in the Himalaya and Hindu Kush regions and Tibetan Plateau in Asia.

Summit co-chair, Canadian John Pomeroy, a water resources and climate change expert, said the loss of water resources in mountain ranges around the world is devastating the communities in those areas. He said it also is destabilizing vast populations downstream.

“Around half of humanity relies upon water and rivers that originate in the high mountains. And, so this is used for irrigation. It is used for power production, hydroelectricity. It is used for our urban and community water supplies and it provides essential water for ecosystems from the mountaintop down to the sea.”

Pomeroy added the rapidly melting mountain glaciers are contributing to rising sea levels. He notes cities along the ocean such as Miami, Venice and Jakarta already are in big trouble.


After Climate Change, This combination of Sept. 14, 1986, left, and Aug. 1, 2019 photos provided by NASA shows the shrinking of the Okjokull glacier on the Ok volcano in west-central Iceland. A geological map from 1901 estimated Okjökull spanned an area of about 38 square kilometers (15 square miles). In 1978, aerial photography showed the glacier was 3 square kilometers. in 2019, less than 1 square kilometer remains. VOA

“For the high mountain communities or valleys in north India, Pakistan, central Asia, their irrigation is the only source of water for agriculture that is currently provided by ice melt from glaciers,” Pomeroy said. “And the glaciers are retreating … In the Western U.S., 90 percent of the water supplies are from the high mountains and they drive the economy.”

The Intergovernmental Panel on Climate Change, which measures the impact of global warming, predicts snow cover, glaciers and permafrost will continue to decline in almost all regions throughout this century.

The summit is calling for urgent action to support more sustainable development in both high-mountain areas and downstream. That will involve disaster risk reduction measures, better early warning systems, climate change adaptation and investment in infrastructure to make communities safer. (VOA)

Eating fruits is one of the most satisfying ways to tackle sweet-tooth cravings while meeting your nutritional needs. Despite many studies and research on fruit consumption in diabetes, there are a lot of speculations on the right kind of fruit consumption and its relation to blood sugar levels.

Eating seasonal and locally available fruit has many health benefits ranging from reducing sugar and inflammation levels to fighting high blood pressure -- thanks to their abundant vitamins and mineral presence! They are a powerhouse of antioxidants like vitamins A, B, C, E, and minerals like iron, calcium, magnesium, and fiber.

The fruits listed below are not just diabetic-friendly but are loaded with fiber and water content which can slow down the sugar spikes and sugar absorption rate. Apples are not just nutritious and filling; According to a study, they are significantly associated with a lower risk of type 2 diabetes if consumed in moderation.

Actress Kangana Ranaut has talked about how her weight adjustments for her latest 'Thalaivii' that "messed up many things" in her body

Actress Kangana Ranaut has talked about how her weight adjustments for her latest 'Thalaivii' that "messed up many things" in her body and left her with "permanent stretch marks". For her role in the film, based on the life of late Tamil Nadu Chief Minister and former actress J. Jayalalithaa, Kangana had to gain 20kg and undergo major physical transformation several times.

She took to Instagram to share her experience, detailing that doing all that over the six months period left her with "permanent stretch marks". "Gaining 20 kgs in 6 months and loosing it all within 6 months that too in my thirties messed up many things in my bodya I also have permanent stretch marks as well but art comes to life with a price and more often than not price is the artist him/herself," she wrote.

"Thalaivii" showcases the varied aspects of Jayalalithaa's life, tracing her journey as an actress at a young age to becoming the face of Tamil cinema, as well as the rise of the revolutionary leader who changed the course of the state's politics. Talking about her upcoming works, Kangana currently has 'Dhaakad'.

She is also shooting for her next 'Tejas', where she plays a fighter pilot. The Indian Air Force was the first of the country's defence forces to induct women into combat roles in 2016. The film takes inspiration from the landmark event. 'Tejas' is directed by debutant Sarvesh Mewara. The film will be RSVP's second film which pays a tribute to the Indian military after the immensely successful film "Uri: The Surgical Strike" which was released in January 2019. (IANS/ MBI)
