Climate Change and Pakistan’s Monsoon Crisis: A Dangerous Convergence

A Warming Climate, A Swelling Monsoon

Climate change is reshaping South Asia’s monsoon dynamics, making rains more erratic and intense. Warmer air holds more moisture, leading to sudden extreme downpours rather than sustained precipitation. These destabilized patterns raise flood risks across vulnerable regions — and Pakistan is no exception.

A detailed climate study found that recent warming (of about 1.2 °C) has increased extremely heavy 5‑day rainfall events by roughly 75% in provinces like Sindh and Balochistan, while extended 60-day rainfall has intensified by nearly 50%. Historical monsoon disruptions, like those in 2010 and 2022, offer critical clues that these shifts are becoming more frequent and dangerous.

The 2025 Flood Season: Facts and Figures

Between June and July 2025, Pakistan endured heavy pre‑monsoon and monsoon rains across multiple provinces — including Punjab, Khyber Pakhtunkhwa, Sindh, Balochistan, Azad Kashmir, and Gilgit‑Baltistan. At least 200 people lost their lives and over 500 were injured, with many others missing or displaced. Punjab saw particularly catastrophic impacts: in a single 24-hour period, 54 people perished, and overall fatalities across the country since late June neared 180. Chakwal reported the highest localized downpour—423 mm, double the typical rainfall for July.

Northern Pakistan’s mountainous regions suffered further crises. A cloudburst in Gilgit-Baltistan triggered flash floods and landslides, killing at least three tourists, stranding dozens more, and prompting joint rescue operations using military helicopters and heavy machinery. A tragic incident in Swat Valley involved tourists swept away by sudden river surges—over 18 fatalities reported and widespread outrage at response delays.

Several intensifying factors converged to worsen humanitarian and infrastructural impacts:

• Geophysical vulnerabilities: Rapid glacier melt and steep terrain amplify runoff and river swelling.

• Urban planning gaps: Inadequate drainage, illegal encroachments along riverbanks, and insufficient floodplain management weakened municipal resilience.

• Governance and disaster response issues: Authorities, especially in Khyber Pakhtunkhwa, were criticized for delayed rescue operations, leading to suspensions of top officials

Flood aftermaths often bring serious health crises. Past experiences show a surge in waterborne diseases—diarrhea, dengue, malaria—and increased malnutrition and respiratory illness risks among displaced populations. Economically, even moderate-scale disasters erode livelihoods, burden health systems, and strain national resources. Similar events in 2022 pushed millions into poverty and destroyed agricultural outputs, housing, and schools.

The monsoon floods striking Pakistan in June–July 2025 underscore a troubling pattern: climate change is transforming monsoon rains into immediate threats rather than seasonal nourishment.

• Intensified rainfall events have increased in frequency and scale.

• Mountain meltwater combined with torrential downpours triggers flash floods.

• Poor planning, inadequate infrastructure, and delayed responses compound devastation.

While mitigation and climate justice remain vital, Pakistan must also invest in climate-resilient infrastructure, robust governance, and early-warning systems to safeguard citizens. Without urgent action, these cycles of disaster may no longer remain exceptional—they could become the norm.
