The Himalayan Thaw and Pakistan’s Looming Instability

The melting glaciers are an unmitigated disaster

As the world echoes with voices about climate change in global conference halls, a quiet catastrophe is unfolding in the north of Pakistan and it is beginning to roar.

The glaciers of the Himalayas, often dubbed the Third Pole, are melting and with them, Pakistan’s water, food, environmental, and hydro-power security, among others, are increasingly under threat.The sky-piercing Hindu Kush–Himalaya–Karakoram (HKH) mountain range provides essential ecological services to over 240 million people directly and supports the livelihoods of 1.9 billion across downstream river basins. It acts as a primary source for 10 rivers in South Asia including the Indus River which is the lifeline of Pakistan’s water, food, and energy security. Any thaw in these frozen reserves translates into a national emergency for Pakistan. A 2025 study on Chitral’s glaciers reports a 31 percent retreat over the past 30 years, alongside a 1.6°C rise in temperature, a clear warning of the looming instability confronting Pakistan.

Unfortunately, this rising temperature is turning these snow-capped mountain peaks into ticking time bombs with consequences cascading into multiple overlapping crises for Pakistan. Ninety percent of Pakistan’s agriculture gets its water from the Indus River system, that is glacier-fed. However, due to the disturbance in the ecology of the Himalayas glacial melt and cryospheric changes, Pakistan’s agricultural production is already decreased by 20 percent in the year 2022 according to the Food and Agriculture Organization.

At the regional level, the establishment of a Joint Himalayan Cooperation Authority involving Pakistan, India, and China is the need of the hour. However, India’s growing weaponization of water resources, as reflected in its recent unilateral suspension of the Indus Waters Treaty, signals a troubling trend. In this context, Pakistan must be proactive, vigilant, and swift in both its policies and responses. We must learn from the disasters of our past and act with foresight, otherwise, we will not just suffer setbacks, and we will slowly fade into destruction, consumed by the very climate crisis we failed to confront.

Agriculture is the lifeline of Pakistan’s economy. It contributes 18 percent% of the country’s GDP and absorbs 18percent of its labour force. With glacier-fed flows becoming erratic, the crop calendar is collapsing. Which is already leading to acute unemployment and  food insecurity, along with weakening of the economy.

Another critical consequence of the Himalayan meltdown is the increasing formation of glacial lakes, and then of Glacial Lake Outburst Floods (GLOFs) and their associated devastation. According to UNDP’s GLOF II Project, Pakistan harbours over 3,000 glacier-formed lakes, at least 33 of which are classified as hazardous. These lakes form when glaciers retreat, and leaved behind unstable water bodies that are dammed by fragile ice or loose debris. These are literal time bombs, capable of blowing at any moment, with extreme unpredictability and destructive power. The collapse of the Hassanabad Bridge in Hunza in 2022 is a chilling example of how sudden and severe these floods can be. As global and regional temperatures continue to rise, the frequency and scale of GLOFs is expected to increase further heightening the risk of widespread flooding, infrastructural damage, and community displacement in Pakistan’s northern regions.

Beyond floods and infrastructure collapse, the melting glaciers are also threatening Pakistan’s energy security. Major dams in Pakistan including Tarbela, Mangla, and Neelum–Jhelum are heavily dependent on glacial flows from the Indus River system. These dams form the backbone of Pakistan’s energy infrastructure, as a significant portion of the country’s electricity comes from hydropower. However, the melting of Himalayan glaciers threatens this energy source in both the short and long term. In the short run, excessive glacial melt and flood-induced overflows can damage dam infrastructure and force emergency spillway releases. This uncontrolled release of water can endanger downstream communities, especially during heavy monsoon rains. Conversely, during dry seasons, reduced snow-pack means insufficient reservoir inflow, causing a sharp decline in hydro-power generation, just when energy demand spikes due to heatwaves.

In the long run, the situation is even more alarming. According to WAPDA’s own Climate Risk Assessment, Pakistan’s hydro  power output could decline by 15–20% by 2040 due to reduced glacial input. It poses a serious risk to a country already strangled by energy shortages, circular debt, and economic instability. A decline in hydro power would force Pakistan to increase LNG and fossil fuel imports, placing further pressure on its fragile economy and increasing carbon emissions, creating a vicious climate-energy-economic cycle.

The crisis doesn’t end at Pakistan’s borders. The regional implications are equally alarming. The glacier melt poses a grave threat to the already fragile regional peace. In the absence of any Joint Glaciers Monitoring mechanism, countries like Pakistan, India, and China can slide into diplomatic and military standoff over the construction of upstream dams like the Kishanganga dam between Pakistan and India, unregulated water diversion, and worsening water insecurity.

In order to address this grave issue, a multi-pronged approach rooted in climate diplomacy, early warning systems, disaster preparedness, and regional cooperation is required. Pakistan must urgently invest in glacier monitoring mechanisms, robust early warning systems for GLOFs, and climate-resilient infrastructure capable of absorbing environmental shocks.

At the regional level, the establishment of a Joint Himalayan Cooperation Authority involving Pakistan, India, and China is the need of the hour. However, India’s growing weaponization of water resources, as reflected in its recent unilateral suspension of the Indus Waters Treaty, signals a troubling trend. In this context, Pakistan must be proactive, vigilant, and swift in both its policies and responses. We must learn from the disasters of our past and act with foresight, otherwise, we will not just suffer setbacks, but we will slowly fade into destruction, consumed by the very climate crisis we failed to confront.
