Climate Change in Pakistan, The Rising Threat and Urgent Call for Action
Pakistan stands at the frontline of the global climate crisis. Despite contributing less than 1% of total global greenhouse gas emissions, the country is among the top 10 most climate-vulnerable nations. Over the past decade, the impacts of extreme weather events, glacial melt, prolonged droughts and unprecedented floods have intensified, placing millions of lives and livelihoods at risk.
Extreme Heat and Heatwaves
In 2025, Pakistan experienced one of the most prolonged and intense heatwaves in its history, lasting from April to July. This Pakistan heatwave 2025 saw temperatures soar well above seasonal norms, affecting urban centers and rural communities alike.
Such heatwaves are no longer rare occurrences between 1997 and 2015, Pakistan faced an average of seven heatwaves per year, and the trend is rising sharply. These events strain public health systems, reduce labor productivity and damage crops, creating a chain reaction of economic and social stress.
Flooding, Monsoons and Glacial Lake Outburst Floods
Pakistan’s diverse geography from the Himalayan glaciers to the Indus plains makes it highly sensitive to climate disruptions. In 2022, record-breaking monsoon rains submerged nearly one-third of the country, killing almost 1,760 people and causing $40 billion in damage.
More recently in July 2025, accelerated glacial melt combined with heavy monsoon rains triggered catastrophic floods in Gilgit-Baltistan, claiming over 70 lives. These events also increase the risk of Glacial Lake Outburst Floods (GLOFs) sudden, destructive surges of water from melting glaciers a direct consequence of rising global temperatures.
Water Scarcity and Agriculture
Once a water-abundant country, Pakistan is now on the verge of absolute water scarcity, with per capita availability dropping from 5,600 m³ in 1947 to just over 1,000 m³ today.
The agriculture sector, which employs around 40% of the workforce, faces growing threats from erratic rainfall, flooding and prolonged droughts. This not only impacts food security but also undermines rural economies and increases migration pressures.
Environmental Degradation and Reforestation Efforts
Deforestation and land degradation amplify the effects of climate change. Pakistan’s forest cover has dropped to between 2% and 5% of total land area, far below the UN-recommended 12–25%.
To combat this, initiatives like the Billion Tree Tsunami and Ten Billion Tree Tsunami have restored vast areas of degraded land, protected mangroves and enhanced biodiversity. While these programs are commendable, they require sustained funding, community participation, and strict monitoring to achieve long term success.
Human and Economic Impact
Climate-related disasters cost Pakistan billions of dollars annually. Beyond the financial losses, the human toll is devastating:
Children face malnutrition and disrupted education due to displacement.
Vulnerable groups including the elderly, women, and low-income communities are disproportionately affected.
Urban infrastructure struggles to cope with extreme weather, leading to housing instability and public health risks.
Why This Matters Globally
Pakistan’s struggle is not an isolated story; it is a warning for the world. As climate change accelerates, countries with limited resources will continue to bear the brunt of disasters they did not cause. This imbalance demands international cooperation, climate financing and technology transfer to help vulnerable nations adapt and build resilience.
