Pakistan and
Climate Changes

2. Weather:
• A short period(24 hours) of temperature and humidity
and air pressure in specific area.
Climate:
• For long period of time (3 to 6 months),temperature
and humidity and air pressure in specific area.
Season:
• When we divide year into different parts according to
temperature .then each part is called season .
• In Pakistan shamse year are classified into 4 season
• Winter (nov,dec,jan,feb).
• Summer (may,june,july,aug).
• Autumn (sep, oct).
• Spring (march,april).

3. Pakistan and Climate Change
o Various studies place Pakistan among
the highly vulnerable countries due to
climate change.
o During last three years country has
witnessed rapid weather shift in various
provinces.
o Monsoon has become highly
unpredictable.
o Country witnessing floods in one
province and drought in other.
o Indus River—lifeline of Pakistani
economy-is becoming highly erratic .

4. Causes of climate changes
• Enhanced concentration of Green House Gases
(GHGs), especially the carbon-dioxide, in the
atmosphere is causing the global warming.
• Impact of climatic changes encompass varied
areas such biodiversity, agriculture, fisheries,
forests, water, energy, food, natural disasters,
etc.
• This could directly impact country’s national,
food, water and energy.

5. Impacts of Climate Change
• More floods and droughts.
• Late monsoon rains.
• Temperature increased.
• Winter shortened.
• More variability in rainfall.
• Shorter snowfall season.
• Early spring snowmelt .
• Accelerated glacial melting.
• May affect water availability, water
quality, ecosystems, etc.
• Decrease forest productivity.

6. Climate Impacts to Health from Increased
Temperatures
• The human body maintains body temperature in ambient temperatures not
exceeding 32 degrees C .
• Above this temperature, heat lost through the skin and sweating .
• Direct impacts to health:
a) Heat cramps – muscular pains and spasms .
b) Heat exhaustion – body fluids are lost through heavy sweating.
c) Heat stroke – is life threatening.
• Indirect impacts:
a) Range of areas that can potentially be affected with gradual and extreme
temperature increases.
b) Includes impacts on ecosystems, water, food, disease-carrying vectors, lifestyle,
community resilience.

8. Storms/Flooding
• Monsoon floods in Pakistan during September, killed
more than 400 people and affected more than 4.5
million others:
• The worst floods were in 2010, when almost 1,800
people were killed and 21 million were affected.

9. Drinking Water Supply
Drying climate causes:
• Changes to land cover and run-off patterns (erosion)
• Increased bushfire risk
• Increased sediment, nutrient and debris.
Flooding can also affect drinking water supplies:
• Coastal intrusion
• Contamination

10. Air Quality
• Weather has a major role in the
development, transport,
dispersion and deposition of air
pollutants.
• Air pollution episodes are often
associated with stationary or
slowly moving air masses.
• Air pollutants and fine particulate
matter may change in response to
climate change.

11. Air Quality

12. Economic Impacts
Economic impacts may be as
follows:
• Loss of income and/or assets.
• Reduction of goods and services.
• Higher costs of insurance, food,
water and energy.
• Financial strain for Governments
and others.
• Impacts on provision of health
services.

13. Social Impacts
Lifestyle and behaviour are likely to be affected in the
following ways:
o Increased temperatures:
o Increases in crime - particularly involving
aggression.
o Accidents - workplace and traffic .
o Decline in physical health .
o Hot nights may cause sleep deprivation.
o Lack of cold water- reduced ability to cool
down.

15. Solution
• Domestic water saving & sea water utilization.
• Strengthening river flow monitoring network &
flood warning system.
• Encourage agriculture-drought management
practices.
• Reduce our consumption of fossil fuels.
• Replacing just 1 incandescent light bulb with 1
compact florescent bulb saves about 150 pounds
of carbon dioxide per year!
