Pakistan’s Changing Climate: What Is Happening and What the Future Could Look Like

Climate change is no longer only a discussion about the distant future.

Across Pakistan, people are experiencing changes in temperature, rainfall, heatwaves, floods, water availability and seasonal patterns. The country’s geography makes it particularly exposed to climate-related risks, from the glaciers and mountains of the north to the Indus Basin, agricultural plains, major cities and the Arabian Sea coastline.

Pakistan contributes only a small share of global greenhouse-gas emissions but remains highly vulnerable to the effects of a changing climate. The World Bank describes Pakistan as highly vulnerable to natural disasters and climate change.

So what exactly is changing?

And what could Pakistan’s climate look like in the coming decades?

What Is Climate Change?

Climate change refers to long-term changes in temperatures, rainfall patterns and other characteristics of the Earth's climate.

The climate has naturally changed throughout Earth's history. However, the current period of warming is primarily driven by human activities that increase greenhouse gases in the atmosphere.

The burning of coal, oil and gas, deforestation, industrial activity, transportation and other activities increase concentrations of gases such as carbon dioxide and methane.

These gases trap additional heat in the atmosphere, causing the planet to warm.

As global temperatures rise, the effects do not appear only as higher average temperatures. Climate change can also influence rainfall, drought, extreme heat, floods, glaciers, sea levels and other parts of the climate system.

Why Is Pakistan Getting Hotter?

Pakistan is experiencing a clear long-term warming trend.

According to the World Bank, Pakistan faces warming rates considerably above the global average. Earlier climate projections estimated potential warming of approximately 1.3°C to 4.9°C by the 2090s compared with the 1986–2005 baseline, depending on future emissions.

More recent World Bank analysis also reports that warming in Pakistan is accelerating, particularly during winter and post-monsoon periods.

The increase is not identical everywhere.

Pakistan contains mountains, plains, deserts, coastal areas and large urban centres. These different environments respond differently to changes in temperature and rainfall.

Heatwaves Are Becoming a Bigger Concern

One of the most visible consequences of warming is extreme heat.

Pakistan has already experienced severe heatwaves. The World Bank notes that the country has gained roughly another month of heatwave days compared with earlier conditions, while the 2015 Karachi heatwave resulted in more than 1,200 deaths.

Future warming is expected to increase extreme heat exposure.

This matters particularly in large cities.

Urban areas can become even hotter because concrete, asphalt and buildings absorb and retain heat. Limited vegetation, high population density and energy demand can further increase heat stress.

The result could be longer and more intense periods of dangerous heat, particularly for outdoor workers, older people and vulnerable communities.

Rainfall Is Changing — But Not Simply Becoming “More” or “Less”

One of the most complicated parts of climate change is rainfall.

It would be misleading to say simply that Pakistan will become wetter or drier everywhere.

Different regions can experience different changes.

World Bank analysis indicates that Pakistan's average annual rainfall has increased over the past half century, but with important regional differences. Future precipitation projections also contain considerable uncertainty.

What is becoming particularly important is extreme rainfall.

A warmer atmosphere can hold more moisture, which can contribute to heavier rainfall events under suitable conditions.

This can create a difficult combination:

Longer dry periods + intense rainfall events

Instead of rainfall being evenly distributed throughout a season, communities can experience periods of limited rain followed by very heavy rainfall.

That creates challenges for agriculture, water management, cities and infrastructure.

Why Are Floods Becoming Such an Important Risk?

Pakistan has always experienced floods, particularly during the monsoon season.

Climate change can increase the intensity of some rainfall events while other factors can increase vulnerability.

These factors include:

• Heavy monsoon rainfall
• Rapid runoff
• River flooding
• Urban drainage limitations
• Development in exposed areas
• Glacial and snowmelt-related hazards
• Changing precipitation patterns

The 2022 floods demonstrated the scale of Pakistan's vulnerability. The World Bank estimated more than $30 billion in damages and economic losses, while approximately 33 million people were affected.

More recently, the 2025 flash floods in Khyber Pakhtunkhwa again demonstrated how quickly extreme rainfall can turn into a major disaster. A World Bank review found that 85% of surveyed households in three severely affected districts received no warning before floodwaters arrived.

Climate change is therefore not simply about whether floods happen.

It is also about how intense, sudden and damaging extreme events can become.

What About Drought?

At the same time, Pakistan faces drought risk.

A warmer climate increases evaporation and can place additional pressure on water resources.

Future projections indicate that drought conditions could become more significant. A recent World Bank assessment projects an increase in severe drought occurrence of around 17% by the 2030s and around 66% by the end of the century under the assessed scenario.

This creates an important paradox:

Pakistan can face both greater flood risk and greater drought risk.

Heavy rainfall does not automatically solve water shortages.

If large amounts of water arrive rapidly, they can cause flooding and then flow away rather than being stored for use during dry periods.

Pakistan’s Glaciers Are Also Changing

Pakistan contains some of the world's most important mountain and glacier systems.

The northern regions are particularly important for the country's water resources.

As temperatures rise, glaciers and snow systems can change.

This creates several concerns.

In the short term, increased melting can contribute to higher flows and hazards such as glacial lake outburst floods.

Over the longer term, changes in glacier mass and snowpack can alter the timing and availability of water.

The World Bank identifies glacier behaviour as an important uncertainty for Pakistan's future water resources, while recent climate assessments also highlight increasing risks from glacier-related hazards.

What Could Happen to Pakistan’s Water?

Water could become one of Pakistan's most important climate challenges.

Pakistan depends heavily on the Indus River system, agriculture and seasonal water flows.

Climate change can affect this system through:

• Changing rainfall
• Higher temperatures
• Glacier and snowmelt changes
• Increased evaporation
• Drought
• Extreme rainfall
• Population growth
• Increasing urban demand

This means the future challenge may not simply be “less water.”

It could be less predictable water.

There may be periods of extreme water availability followed by periods of severe shortage.

What About Pakistan’s Coast?

Climate change is also affecting Pakistan's coastline.

Sea-level rise can increase risks for low-lying coastal areas.

The World Bank reports that Pakistan's sea level has already been rising and identifies the Indus Delta and low-lying coastal areas south of Karachi toward Keti Bander as particularly exposed to future sea-level risks.

Coastal communities can face several connected problems:

• Coastal flooding
• Erosion
• Saltwater intrusion
• Damage to infrastructure
• Changes to groundwater
• Pressure on agriculture and livelihoods

The Indus Delta is particularly important because it connects climate change with water management, ecosystems, agriculture and coastal communities.

Will Pakistan Have More Extreme Weather?

Climate projections suggest that Pakistan will face increasing exposure to climate extremes.

These can include:

• Extreme heat
• Heavy rainfall
• Flooding
• Drought
• Landslides
• Glacier-related hazards
• Coastal flooding

The World Bank projects an increase in extreme climate events and flood exposure, while its recent Pakistan climate analysis identifies increasing extreme heat and precipitation-related flood risks through the coming decades.

However, climate projections are not predictions of exactly what will happen in a particular city on a particular day.

They describe long-term trends and risks.

What Could Pakistan Look Like by 2050?

By the middle of the century, Pakistan is expected to be warmer.

The exact amount of warming will depend partly on future global greenhouse-gas emissions.

The consequences could include:

Hotter summers

Extreme heat could become more common, with higher nighttime temperatures making it harder for people and buildings to cool down.

Greater pressure on water

Higher temperatures and changing rainfall can increase competition for water between agriculture, households, industry and ecosystems.

More pressure from extreme rainfall

Heavy rainfall events could create greater flood risks, particularly where drainage and flood-management systems are inadequate.

Greater pressure on cities

Pakistan's growing urban population means more people and infrastructure may be exposed to heat and flooding.

Changing agricultural conditions

Higher temperatures, changing rainfall and water availability can affect crop productivity.

These changes will not necessarily occur equally across the entire country.

What Could Happen by 2100?

The longer-term picture becomes more dependent on global emissions.

Under higher-emissions scenarios, Pakistan and the wider South Asian region could experience substantially greater warming.

IPCC projections indicate that South Asia could experience much higher temperatures by the end of the century under high-emissions scenarios, while summer monsoon precipitation is also projected to increase.

For Pakistan, the long-term consequences could include:

• Much more frequent extreme heat
• Greater water stress
• Stronger pressure from extreme rainfall
• Greater flood exposure
• Increasing coastal risks
• Changes in glacier and snow systems
• Higher pressure on agriculture
• Increasing challenges for cities and infrastructure

The scale of these impacts will depend significantly on future global emissions and Pakistan's ability to adapt.

Why Is Pakistan Particularly Vulnerable?

Climate risk is not determined only by temperature or rainfall.

Risk also depends on exposure and vulnerability.

For example, two cities can experience the same rainfall event but suffer very different consequences if one has better drainage, stronger infrastructure and more effective emergency systems.

Pakistan's vulnerability is influenced by factors such as:

• Rapid population growth
• Urban expansion
• Infrastructure gaps
• Water stress
• Dependence on agriculture
• Poverty and inequality
• Exposure to floods and heat
• Limited disaster preparedness in some areas

This is why climate change is both an environmental issue and a development issue.

Can Pakistan Reduce the Impact?

Yes — although adaptation cannot eliminate every climate risk.

Pakistan can reduce vulnerability through better planning and investment.

Important areas include:

Better Urban Planning

Cities can incorporate drainage, green spaces, heat management and flood-risk considerations into future development.

Climate-Resilient Infrastructure

Roads, bridges, buildings, drainage systems and utilities can be designed to withstand changing climate conditions.

Better Water Management

Improving water storage, irrigation efficiency, groundwater management and conservation can help Pakistan cope with increasing variability.

Early Warning Systems

Better forecasting and communication can give communities more time to respond to floods, heatwaves and other hazards.

Climate-Resilient Agriculture

Farmers can adapt through improved irrigation, crop choices, water management and agricultural practices.

Protecting Natural Systems

Forests, wetlands, river systems and coastal ecosystems can provide natural protection while supporting biodiversity and livelihoods.

What Does Climate Change Mean for Future Generations?

The biggest question is not whether Pakistan's climate will change.

It already is.

The bigger question is how quickly it changes and how prepared Pakistan is for those changes.

Climate projections show a future with higher temperatures and increasing pressure from extreme weather. But the severity of future impacts depends on both global emissions and the choices made today.

The difference between a highly vulnerable future and a more resilient future will depend on planning, investment, adaptation and international efforts to reduce greenhouse-gas emissions.

Final Thoughts

Pakistan's climate is changing across multiple dimensions.

The country is becoming warmer. Extreme heat is becoming a greater concern. Rainfall patterns are changing, while intense rainfall can create serious flood risks. At the same time, drought, water stress, glacier changes and sea-level rise create additional long-term challenges.

These changes are not isolated environmental problems.

They can influence agriculture, health, water, infrastructure, cities, livelihoods and Pakistan's broader economy.

The future is not completely predetermined.

Global emissions will influence the level of future warming, while Pakistan's investments in resilience, infrastructure, water management, urban planning and disaster preparedness can influence how severely communities experience climate impacts.

Understanding these changes is therefore the first step toward preparing for them.

Deal One Real Estate believes that understanding Pakistan's changing environment is also important for understanding the future of its cities, communities and infrastructure.
