Glacial Lake Outburst Flood
A glacial lake outburst flood (GLOF) is a type of outburst flood caused by the failure of a dam containing a glacial lake. An event similar to a GLOF, where a body of water contained by a glacier melts or overflows the glacier, is called a jökulhlaup. The dam can consist of glacier ice or a terminal moraine. Failure can happen due to erosion, a buildup of water pressure, an avalanche of rock or heavy snow, an earthquake or cryoseism, volcanic eruptions under the ice, or massive displacement of water in a glacial lake when a large portion of an adjacent glacier collapses into it. Increasing glacial melting because of climate change, alongside other environmental effects of climate change (i.e. permafrost melting) mean that regions with glaciers are likely to see increased flooding risks from GLOFs. This is especially true in the Himalayas where geologies are more active. A 2023 study found 15 million people at risk from this hazard, mostly in China, India, Nepal, Pakistan, ...

Sub-glacial Lake
A subglacial lake is a lake that is found under a glacier, typically beneath an ice cap or ice sheet. Subglacial lakes form at the boundary between ice and the underlying bedrock, where liquid water can exist above the lower melting point of ice under high pressure. Over time, the overlying ice gradually melts at a rate of a few millimeters per year. Meltwater flows from regions of high to low hydraulic pressure under the ice and pools, creating a body of liquid water that can be isolated from the external environment for millions of years. Since the first discoveries of subglacial lakes under the Antarctic Ice Sheet, more than 400 subglacial lakes have been discovered in Antarctica, beneath the Greenland Ice Sheet, and under Iceland's Vatnajökull ice cap. Subglacial lakes contain a substantial proportion of Earth's liquid freshwater, with the volume of Antarctic subglacial lakes alone estimated to be about 10,000 km3, or about 15% of all liquid freshwater on Earth.

Gilgit-Baltistan (; ), formerly known as the Northern Areas, is a region administered by Pakistan as an administrative units of Pakistan, administrative territory and consists of the northern portion of the larger Kashmir region, which has been the subject of a Kashmir#Kashmir dispute, dispute between India and Pakistan since 1947 and between India and China since 1959.The application of the term "administered" to the various regions of Kashmir and a mention of the Kashmir dispute is supported by the WP:TERTIARY, tertiary sources (a) through (e), reflecting WP:DUE, due weight in the coverage. Although "controlled" and "held" are also applied neutrally to the names of the disputants or to the regions administered by them, as evidenced in sources (h) through (i) below, "held" is also considered politicised usage, as is the term "occupied," (see (j) below).

Kathmandu, Nepal
Kathmandu () is the capital and largest city of Nepal, situated in the central part of the country within the Kathmandu Valley. As per the 2021 Nepal census, it has a population of 845,767 residing in 105,649 households, with approximately 4 million people in the surrounding metropolitan area. The city stands at an elevation of 4,344 feet (1,324 metres) above sea level. Recognized as one of the oldest continuously inhabited places in the world, Kathmandu's history dates back to the 2nd century AD. Historically known as the '' Nepal Mandala'', the valley has been the cultural and political hub for the Newar people, a significant urban civilization in the Himalayan region. Kathmandu served as the royal capital of the Kingdom of Nepal and is home to numerous palaces, temples, and gardens reflecting its rich heritage. Since 1985, it has hosted the headquarters of the South Asian Association for Regional Cooperation (SAARC). Today, Kathmandu remains the epicenter of Nepal's hi ...

Alps
The Alps () are some of the highest and most extensive mountain ranges in Europe, stretching approximately across eight Alpine countries (from west to east): Monaco, France, Switzerland, Italy, Liechtenstein, Germany, Austria and Slovenia. The Alpine arch extends from Nice on the western Mediterranean Sea, Mediterranean to Trieste on the Adriatic Sea, Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrust fault, thrusting and Fold (geology), folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French–Italian border, and at is the highest mountain in the Alps. The Alpine region area contains 82 peaks higher than List of Alpine four-thousanders, .

Retreat Of Glaciers Since 1850
The retreat of glaciers since 1850 is a well-documented effects of climate change, effect of climate change. The retreat of Mountain glacier, mountain glaciers provides evidence for the Instrumental temperature record, rise in global temperatures since the late 19th century. Examples include mountain glaciers in western North America, Asia, Alps, the Alps in central Europe, and tropical and subtropical regions of South America and Africa. Since glacial mass is affected by long-term climatic changes, e.g. Precipitation (meteorology), precipitation, Temperature, mean temperature, and cloud cover, glacial mass changes are one of the most sensitive indicators of climate change. The retreat of glaciers is also a major reason for sea level rise. Excluding peripheral glaciers of Ice sheet, ice sheets, the total cumulated global glacial losses over the 26 years from 1993 to 2018 were likely 5500 gigatons, or 210 gigatons per year.Fox-Kemper, B., H.T.
