Devastating Climate Chaos: Pakistan Endures Successive Disasters Despite Less Than 1% Global Emissions

Pakistan climate disasters are becoming a terrifying norm. Despite contributing less than 1% of global carbon emissions, Pakistan is enduring successive climate catastrophes that have left the nation reeling — from flash floods and heatwaves to glacier melt and drought.

These devastating climate disasters reveal how developing nations are facing the harshest effects of a crisis they did little to cause. Climate experts warn that Pakistan’s geographic diversity — from towering mountains to low coastal plains — makes it uniquely vulnerable to both compound and sequential climate impacts.

Compound and Sequential Climate Effects: A Deadly Chain Reaction

Scientists describe compound climate effects as multiple hazards—heatwaves, floods, droughts—occurring simultaneously or in close succession. Sequential effects occur when one disaster triggers another, amplifying destruction.

A 2024 Frontiers in Climate study confirmed that Pakistan’s 2022 floods were driven by both compounding and sequential phenomena. According to Fahad Saeed, a senior climate scientist at Climate Analytics, “Pakistan’s vulnerability lies in its geography. With just 1,600 kilometers of latitudinal range, we have the second-highest peak in the world and vast lowlands — any global temperature rise directly impacts us.”

Flash Floods in Buner: A Grim Reminder

On August 15, 2025, a cloudburst dumped over 150 millimeters of rain in one hour in Buner, Khyber Pakhtunkhwa, triggering a devastating flash flood. More than 300 people were killed as torrents of mud and rock swept away homes, hotels, and shops.

“In my whole life, I never saw anything like this,” said Tariq Zaman, a local resident. “My friend lost 18 members of his family in a single day.”

This heartbreaking incident underscores how mountainous regions — long considered climate buffers — are now becoming disaster hotspots due to unpredictable weather extremes.

Scientific Evidence: Geography and Vulnerability

Pakistan’s climate vulnerability is driven by its unique geography. The Hindu Kush-Himalaya-Karakoram (HKHK) region holds the world’s largest non-polar glaciers, often called the “Water Towers of Asia.”

According to Waqar Ahmed, an environmental scientist at the University of Karachi, “It’s not necessary that the carbon-emitting countries face the same impacts. Pakistan is an unfortunate example of global inequality in climate suffering.”

Meteorologist Anjum Zaigham from the Pakistan Meteorological Department notes that emissions from India and China are contributing to local warming. Northern Pakistan has already witnessed a 2°C temperature increase, leading to frequent Glacial Lake Outburst Floods (GLOFs).

Northern Melting, Southern Drowning: A Dual Crisis

While the north melts, the south drowns. A 2024 Nature India report found that the Arabian Sea — bordering Sindh and Balochistan — is warming faster than global averages. This change drives erratic monsoons, coastal flooding, and severe drought cycles.

These contrasting climate events reveal Pakistan’s dual crisis — from glacier melt in the north to rising sea levels in the south, a reality mirrored by no other country at such scale.

The Karachi Heat Wave: When Cities Became Ovens

In June 2015, Pakistan experienced its deadliest heatwave, killing over 2,000 people — 1,200 of them in Karachi alone.

“People fainted in front of me,” recalls Rizwan Khan, a Karachi resident. “It felt like breathing fire.”

Climate activist Yasir Darya of the Climate Action Centre Pakistan says, “Before 2015, peak temperatures occurred for a few days. Now, heatwaves last for weeks.”

Then came the 2020 urban floods, when 230 mm of rain in 12 hours submerged Karachi. With climate change accelerating, urban infrastructure is now on the frontline of Pakistan’s crisis.

The 2022 Mega Floods: A National Catastrophe

The 2022 monsoon floods were Pakistan’s worst climate disaster in history. Over 33 million people were affected, 1,700 died, and the economic loss exceeded $40 billion.

In Balochistan, rainfall increased by 500% over the previous decade. Scientists from npj Climate and Atmospheric Science later confirmed links between European and Chinese heatwaves and Pakistan’s floods, highlighting the global chain reaction of climate systems.

The Thar Desert’s Changing Climate

The Thar Desert, once synonymous with drought, is now witnessing unexpected rainfall and deadly lightning storms. Between 2016 and 2024, over 350 people died due to lightning — a sign of changing atmospheric dynamics.

“The warmer atmosphere holds more water vapor, leading to more rainfall and lightning,” said Fahad Saeed. “This is the Clausius-Clapeyron effect in action.”

Locals blame industrial projects like the Thar Coal Project for increasing storm intensity, though scientific studies remain limited.

Rising Seas and Vanishing Deltas

The Sindh delta, once a fertile region, is vanishing into the Arabian Sea. Sea intrusion has already swallowed 15 of 17 creeks, displacing thousands. Experts predict that 2.3 million people could become climate migrants by 2050.

“Sea-level rise may be slow, but it’s a permanent disaster,” warns Saeed. “It’s reshaping Pakistan’s geography forever.”

Climate Policy and the Road Ahead

Pakistan’s National Climate Change Policy (2012) was a critical step, but implementation remains weak. A 2024 Transparency International report cited “lack of political will, poor coordination, and minimal public participation.”

Senator Musadik Malik, Pakistan’s Climate Minister, said:

“Our adaptation and mitigation plans need multilateral funding. Since COP28’s creation of the Loss and Damage Fund, Pakistan has not received a single dollar.”

Experts agree that without urgent global financing, Pakistan’s recovery and resilience will remain limited.

Conclusion: A Call for Global Climate Justice

The story of Pakistan climate disasters is one of injustice and urgency. A nation contributing almost nothing to the climate crisis is paying its heaviest price.

“We need to move toward zero carbon immediately,” stresses Waqar Ahmed.

If compound and sequential climate effects continue unchecked, Pakistan could face irreversible collapse — a warning for the world to act, not just sympathize.

The time for climate justice is now.
