#ClimateChange and anthropogenic nature destruction in the name of "development" continue to wreck havoc across the most vulnerable areas first.

And by that I mean mountainous communities in the vicinity of melting #Glaciers. If you live in the Alps or any area classed as a mountain range, I'd be packing up to move to flatter terrain outside flood zones at the foothills.

GILGIT: Landslides continued to affect many areas of Gilgit-Baltistan on Tuesday, even as the weather improved after four days of intermittent rain and snowfall. With climate change making weather patterns erratic, the mountainous region received heavy rainfall and snowfall during months when the weather is relatively better. On Tuesday, landslides occurred in Chichala village in Deral valley of Diamer, according to police. The falling rocks damaged a home, livestock shelters, trees and other properties. Landslides also damaged many connecting roads in the region.

The Chipurson Road in upper Hunza was blocked due to landslides, cutting off locals’ access to other parts of the region. Police said the Karakoram Highway, Baltistan Road and other major roads have been opened for traffic on Tuesday after landslides blocked the roads. Internet and mobile services and electricity supply also remained suspended in many areas, particularly in Ghizer and Ghanche. Locals have urged the immediate restoration of electricity and communication services. In Astore, landslides damaged electricity transmission lines. Adqil Hussain Bagiri, a local resident told Dawn that residents in upper areas of Astore were facing difficultes after snowfall and rain. He said families in Daskhrim village were living under the open sky as several houses were partially damaged after snowfall and rain. Locals have urged the government to provide shelter and rehabilitation to the affected ‘people of Daskhrim.

Earlier on Monday, a foreign tourist was killed another injured as falling rocks during a landslide hit their vehicle in Ghanche.

In Skardu, a mother and her two daughters were seriously injured when a landslide hit their home.

Minister’s visit

Federal Minister for Climate Change Senator Mosaddiq Malik and other offifieals of the Ministry of Climate Change visited Shigar with a UNDP delegation to review the newly installed early warning system.

According to a statement, the minister reviewed losses caused to the local population due to the melting of glaciers and the bursting of glacial lakes.

Baltistan Division Commissioner Kamal Khan, Shigar Deputy Commissioner Waliullah Falahi and Gilgit-Baltistan Disaster Management Authority Director General Zakir Hussain briefed the delegation on various projects.

Durch das #Schmelzen der #Gletscher entstehen weltweit neue Seen.

Eine Studie der Universität #Potsdam zeigt jedoch, dass sich vor allem kleinere #Gletscherseen entleeren und nicht zwangsläufig größere #Fluten drohen.

Besonders in den #Alpen, #Peru und #Norwegen wurden Seen künstlich stabilisiert, während in Regionen wie dem #Himalaya oder #Alaska das #Gefahrenpotenzial wächst.

‘Catastrophic’ 2023 lake outburst in India driven by glacial melt and permafrost thaw

#ClimateChange played a key role in the “catastrophic” 2023 floods in the Himalayan state of Sikkim in #India, a new study says.
The breach of one of the “largest, fastest-growing and most hazardous” glacial lakes in Sikkim, the South #Lhonak lake, led to cascading floods that killed 55 people and washed away a 1,200 megawatt (MW) #hydropower dam.
The event was identified as a glacial lake outburst flood (#GLOF), which is a sudden release of water from a lake fed by glacial melt.
#Sikkim is a small Himalayan state in north-east India, bordering #China in the north, #Bhutan in the east, #Nepal in the west and the state of West #Bengal in the south.
Part of the eastern #Himalaya, Sikkim is host to more than 90 #glaciers and #Kanchenjunga, the world’s third-highest peak. Sikkim serves as the origin and upper river basin for the #Teesta river, one of the largest tributaries of the #Brahmaputra river system.

Der #Klimawandel zerstört #Wohnungen und #Infrastruktur:

Schonmal was von #GLOF gehört?

Ein #Gletscherseeausbruch hat in #Juneau, #Alaska, zu beispiellosen #Überschwemmungen geführt, bei denen mehr als 100 Häuser beschädigt wurden. Der Ausbruch ereignete sich, als der See am Suicide Basin durch den #Gletscherrückgang überlief, ausgelöst durch hohe #Niederschläge im Juli und den durch den #Klimawandel bedingten #Gletscherschwund.

I often remark to friends about #Pakistan 's mountainous north being unsuitable for life now thanks to #ClimateChange induced melting, flooding, and landslides.

The #Karakorum #Highway the world's highest such motorway connecting Pak to #China should be thought of a "seasonal" road now, gets washed away on an annual basis, sometimes more frequently.

We cannot afford to rebuild every year!

‘Unprecedented’ Flooding Hits Juneau, Alaska, After Glacier Outburst

“A rush of water unleashed by an ailing glacier swelled an Alaska river to record levels Tuesday and caused destructive flooding in Juneau nearly a year to the date of a similar significant event.
More than 100 homes have been damaged or impacted by the so-called glacial lake outburst flooding along the Mendenhall River in the Mendenhall Valley, according to city officials, who characterized the flood severity as “unprecedented.”
Glacial lake outbursts happen when a lake of melting snow and ice and rain “drains rapidly…”

Further north, in #Pakistan 's mountainous province of #GilgitBaltistan, a #heatwave the past week has cause #FlashFlood and #GLOF or a Glacial Lake Outburst Flow, a wall of water that floods down mountains once it's ice wall melts and breaks like a dam.

GLOFs have become "common" in Northern Pakistan in the past decade, washing away infrastructure, towns and farms almost annually.
