Deadly Monsoon Rains in Pakistan: Human Actions Drive Climate Crisis, Say Scientists
Human-induced climate change made Pakistan’s monsoon 15% heavier in 2025, causing deadly floods and exposing its climate vulnerability. Urgent resilience and finance needed.
The deadly monsoon rains in Pakistan this year have brought catastrophic consequences, with 15% more rainfall than the national average. While monsoons are a seasonal lifeline for agriculture and water reservoirs, 2025 has seen them transform into a climate-induced calamity.
According to a recent scientific study by the World Weather Attribution (WWA) group, the intensification of rainfall and resulting floods were directly amplified by human actions, particularly fossil fuel emissions that warm the planet and supercharge weather systems.
Heavier Rains, Higher Death Toll
From June 26 to August 3, relentless monsoon rains lashed northern Pakistan, triggering flash floods, infrastructure collapse, and widespread displacement. At least 300 people lost their lives, with 242 deaths recorded in the northern regions alone.
Despite the downpours not being record-breaking by historical standards, they still led to an unusually high death toll. According to Dr. Mariam Zachariah from Imperial College London, this underscores a worsening climate vulnerability, where even moderate rainfall now results in disproportionate human and economic losses.

What the Science Says
The WWA report, which involved 18 experts from Pakistan, the UK, France, and the Netherlands, revealed that the 30-day monsoon period in 2025 was 15% more intense due to climate change.
The study used historical weather data and advanced climate modeling to demonstrate how the warming of 1.3°C above pre-industrial levels has altered Pakistan’s monsoon dynamics. In fact, such heavy rainfall events are now expected once every five years, instead of once a decade.
If climate change were not accelerating due to human activity, the rains would have been significantly less intense.
Pakistan’s Readiness: A Global Wake-Up Call
Despite contributing just 0.5% to historical global carbon emissions, Pakistan ranks 152nd in the Global Climate Adaptation Readiness Index, highlighting a troubling mismatch between risk and preparedness.
As monsoon seasons grow more violent, Pakistan’s lack of resilience — in terms of infrastructure, planning, and disaster response — exposes millions to threats that are no longer “natural disasters” but human-amplified tragedies.

Fossil Fuels and the Climate Clock
The report delivers a clear warning: monsoon rains will keep intensifying until the world abandons fossil fuels and embraces renewable energy. Dr. Zachariah emphasized:
“Every tenth of a degree of warming will lead to heavier monsoon rainfall.”
This underscores why climate action is time-sensitive. The longer the transition to clean energy is delayed, the more frequent and intense such deadly monsoons will become.
Pakistan’s energy mix still relies heavily on coal, oil, and natural gas, leaving it doubly exposed — both as a victim and as a contributor to emissions growth.
Adaptation Finance: A Missing Piece
While Pakistan acknowledges the growing climate risks, the lack of adaptation finance is a major hurdle. According to the report:
-
Pakistan needs $40–50 billion annually for climate resilience.
-
Without adaptation, climate damage could cost Pakistan $1.2 trillion by 2050.
The UN Environment Programme echoes this concern, estimating that global adaptation finance needs to hit $300 billion by 2035. Currently, only $28 billion is being disbursed, leaving a massive shortfall.

Policy, Planning, and the Path Ahead
Despite awareness, Pakistan’s long-term planning remains fragmented. Following the 2022 floods, which killed over 1,700 people, there were promises of national adaptation frameworks and disaster-resilient infrastructure.
But as the 2025 floods show, execution is still lacking. Emergency declarations, relief operations, and infrastructure repairs remain reactive, not preventive.
Meanwhile, record-breaking temperatures — like the 48.5°C spike in July 2025 — paired with torrential rains illustrate how compound climate threats are becoming the new normal.

Conclusion
The deadly monsoon rains in Pakistan are not merely weather events — they are the consequences of global inaction and domestic under-preparedness. The 15% increase in rainfall may seem small, but the devastation it caused is immense and preventable.
To avoid future tragedies, Pakistan must:
-
Urgently invest in flood-resilient infrastructure.
-
Strengthen early warning systems.
-
Transition away from fossil fuels.
-
Secure climate finance from global partners.
The world, especially high-emission countries, must acknowledge their role in amplifying climate disasters in vulnerable nations like Pakistan — and take responsibility through urgent financial and technological support.
