Glacial Outflow event (GLOF) above Juneau, Alaska. Spot called "Suicide Basin". (do I have to CW poorly named geological features? ))

Great summarization of where #Pakistan 's changing climate currently stands, by Ali Tauqeer, a #ClimateAction stalwart in the region.

"intensity of rainfall has increased exponentially, the number of rainy days during the monsoons has decreased"

"with temperatures up to 8°C above normal .. dramatically increased moisture capacity, setting the stage for devastating downpours. "

Ein #Gletscherseebruch in #Tibet hat im nepalesischen Rasuwa-Tal eine tödliche #Sturzflut ausgelöst.

Neun Menschen starben, über 20 werden vermisst. Zerstört wurden u. a. drei #Wasserkraftwerke und die wichtige Freundschaftsbrücke.

Ursache war ein sogenannter #GLOF (Glacial Lake Outburst Flood), verstärkt durch den #Klimawandel.

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.

Der #Klimawandel erhöht das #Risiko von Seetsunamis. Durch den #Temperaturanstieg schmelzen #Gletscher, was die Stabilität von #Bergwänden schwächt und zu #Erdrutschen führt. Diese können in Seen große Wellen auslösen. Forscher warnen vor der wachsenden Gefahr in Regionen wie #Alaska, wo solche Ereignisse zunehmend auftreten.

(nicht zu verwechseln mit #GLOF)
