Nepal Tragedy Raises Fears of Massive Glacier Melt in Pakistani Mountains

Image
Northern Pakistan is home to over 13,000 glaciers which pose a risk of catastrophic flash floods similar to the recent flash floods in Nepal. Pakistani officials have warned that shifts in glacier behavior are increasing the risk of glacial lake outburst floods (GLOF), particularly in Gilgit-Baltistan and Khyber Pakhtunkhwa, where communities face growing exposure to sudden flooding and landslides.  Glacial Lake in Pakistan's Gilgit-Baltistan Region. Source: AIGEO360 Pakistan is actively monitoring its glaciers using real-time weather tracking and roughly 350 sensor devices installed by the National Disaster Management Authority (NDMA) and the Pakistan Meteorological Department (PMD) to mitigate glacial flash flood risks.  This year, the PMD reported record-breaking summer heat across northern valleys (such as Chilas reaching 48.5°C and Bunji hitting 46.1°C), accelerating ice melt in Gilgit-Baltistan region and Khyber Pakhtunkhwa province. The heat triggered two major GLOF eve...

Bridge Collapse Amid Heat Wave in Pakistan Raises Fears of Massive Glacier Melt Flooding

Image
Record-high temperatures in Pakistan caused Shisper glacier to melt rapidly, triggering the collapse of the Hassanabad Bridge along the Karakoram Highway last week.  With 7,253 known glaciers, Pakistan is home to more glacial ice than any other country on earth outside the polar regions. If these start melting in increasingly severe heat waves, there could be massive flooding in the country. Pakistan is among the most vulnerable to climate change.  Hasanabad Bridge Collapse in Pakistan India and Pakistan have been hit by a severe heat wave very early this summer.  Jacobabad, a city in Sindh province, hit 122ºF (50ºC) in April, one of the highest April temperatures recorded in the world. Dadu, another city in Sindh, recorded 117ºF (47ºC). "This is the first time in decades that Pakistan is experiencing what many call a 'spring-less year," Pakistan's Minister of Climate Change, Sherry Rehman said in a statement. The consequences of rising temperatures in South Asia coul...

Are Pakistan's Glaciers Melting Away?

Image
A recent headline in Pakistan's Express Tribune newspaper declared:  "Pakistan's glaciers melting faster than rest of the world" . A few days later, I heard an ex-Met Department officer in Pakistan repeat the same alarm on a Geo TV show "Capital Talk" anchored by Hamid Mir. Are these people right? Recognizing it's too important an issue to let go, I decided to look into the facts and data as reported in science journals. Quickly, I came upon "Karakoram Anomaly". I learned that it's a term used to describe the fact that, unlike other mountainous regions, the Karakoram glaciers which supply most of Pakistan's river water are growing rather than shrinking. Baltoro Glacier in Karakoram National Park in Pakistan Pakistan is home to the most heavily glaciated area outside the polar regions of the Arctic and Antarctica. The massive glaciers of Baltoro and Biafo stretch for over 60 kilometers each in the  Karakoram Mountains , accor...
