Mountain regions cover about a quarter of the Earth’s land surface and are home to around 1.1 billion people.
Many rivers start in the mountains and supply freshwater to over half the world’s population.
The glaciers in the Hindu Kush Himalaya and Tibetan Plateau region are known as the Third Pole.
They are melting at an increasing rate according to delegates at the recent summit run by the World Meteorological Organisation.
We have reported on the issue in the past on PlanetSKI:
Presentations from around the globe highlighted that glacier and snow melt means a long-term threat to the security of water supplies for billions of people.
Swiss glaciers have lost 10% of their volume in the past five years.
We reportered earlier on the claim:
500 smaller glaciers have disappeared, and by the end of the century,90% of the remaining 4,000 glaciers may melt.
During the summer of 2019 the equivalent of Switzerland’s annual national drinking water consumption melted from its glaciers in just 15 days, according to MeteoSwiss.
“Climate change and development are creating an unprecedented crisis in our high mountain earth system that threatens the sustainability of the planet.,” said a call for action at the summit.
“There is great urgency to take global action now to build capacity, invest in infrastructure, and make mountain and downstream communities safer and more sustainable. ”
“This action must be informed by science, local knowledge, and based on trans-disciplinary approaches to integrated observations and predictions,” it says.
