Monsoon Catastrophe: How Climate Change is Drowning Pakistan

Monsoon flooding in Pakistan has once again unleashed devastation. Since July 2025, torrential rains and flash floods have killed more than 700 people, displaced thousands, and inundated Karachi, a port city of nearly 20 million people.

The scenes recall the 2022 disaster, when floods submerged one-third of the country and displaced over 8 million people. What was once a life-giving monsoon season for farmers has now turned into a recurring nightmare.

Pakistan’s struggle with climate extremes—from lethal heat waves to flash floods—highlights the urgent need for resilience and climate adaptation.

Why Pakistan Gets Extreme Floods

The causes of monsoon flooding in Pakistan are rooted in both global warming and local vulnerabilities. Rising global temperatures intensify the water cycle—causing more evaporation, greater atmospheric moisture, and heavier downpours.

Meanwhile, the Himalayas, often called the “Third Pole,” are heating at alarming rates. Accelerated glacier melting feeds Pakistan’s river systems, compounding flood risks.

Glacial Lake Outburst Floods (GLOFs) are particularly dangerous. On August 22, 2025, a GLOF in Gilgit-Baltistan destroyed dozens of homes, blocked a river, and forced the evacuation of schools. Earlier torrential rains in the region triggered deadly landslides, stranding nearly 200 people.

Glacial Melting and Climate Risks

Earth’s cryosphere—its glaciers, ice sheets, and snowpack—acts as a global thermostat by reflecting up to 90% of sunlight. But as this reflective shield disappears, warming accelerates.

• In the early 20th century, Himalayan warming averaged 0.10°C per decade.
• By the 21st century, it accelerated to 0.32°C per decade.

This rapid warming increases flood risks downstream, particularly in Pakistan’s Indus River Basin, which sustains over 220 million people.

Heat Waves and the Indus Basin

The July 2025 heat wave intensified Pakistan’s flood crisis. Temperatures in Chilas soared to 48.5°C (119°F), melting glaciers faster than usual.

Such extreme heat events accelerate glacier retreat and increase flash flood risks. The Indus Basin, home to Pakistan’s breadbasket, becomes doubly vulnerable—farmers face drought when rains fail and catastrophic flooding when they arrive.

Deforestation and Population Growth

Pakistan’s population has tripled since 1980, reaching 250 million. About 96 million people live along rivers and floodplains—areas highly vulnerable to flooding.

Urban expansion, poor planning, and deforestation worsen the crisis. Between 2001 and 2024, Pakistan lost nearly 8% of its tree cover. Forests that once absorbed rain and slowed runoff are gone, replaced by concrete sprawl and unsafe housing.

Deforestation not only accelerates mudslides but also removes natural barriers against flash floods.

Disaster Preparedness and Gaps

Despite its repeated disasters, Pakistan ranks 150th out of 192 countries in disaster readiness (Notre Dame Global Adaptation Initiative).

The National Disaster Risk Reduction Strategy (2025–2030) outlines plans for resilience, but progress remains limited. Key challenges include:

• Weak institutional coordination
• Insufficient early warning systems
• Poor drainage and outdated infrastructure
• Lack of financial resources
• Political instability hindering rapid response

While urban areas like Karachi suffer from poor drainage, rural areas face collapsing embankments and unsafe housing.

Nature-Based Solutions and Global Responsibility

Experts argue that nature-based solutions can reduce flood risks:

• Reforestation to stabilize soil and reduce erosion.
• Wetlands restoration to absorb excess rainwater.
• Land-use planning to avoid risky floodplain construction.

Pakistan also needs climate-smart infrastructure, expanded early warning systems, and education programs that embed disaster awareness.

But local action isn’t enough. The international community must recognize that Pakistan emits less than 1% of global greenhouse gases, yet faces disproportionate impacts.

The Loss and Damage Fund, agreed upon at COP27, must prioritize vulnerable nations like Pakistan to strengthen resilience and adaptation.

Conclusion: From Crisis to Resilience

The deadly monsoon flooding in Pakistan is not just a seasonal tragedy—it’s a climate emergency. With over 700 lives lost in 2025 and millions facing recurring displacement, Pakistan stands at the frontline of the global climate crisis.

What was once a blessing—the summer rains—is fast becoming a curse. But with resilient planning, nature-based solutions, international cooperation, and bold governance, Pakistan can turn the tide.

The future depends on whether policymakers treat these disasters as warnings—or allow them to become an endless cycle of tragedy.
