What is the difference between weather and climate?

Weather refers to short term atmospheric conditions
while climate is the weather of a specific region
averaged over a long period of time. Climate change
refers to long-term changes.

Climate

Climate is the long-term pattern of weather in a

particular area.

Weather can change from hour-to-hour, day-to-day,

month-to-month or even year-to-year. A region's

weather patterns, usually tracked for at least 30 years,

are considered its climate

Objectives:
Clarify the factors that affect climate and cause it to change.

Climate Change

Climate change refers to seasonal changes over a long period
of time.
• Worldwide, people are paying serious attention to climate
change.
• Because so many systems are tied to climate, such as,
people, plants and animals live, such as food production,
availability and use of water, and health risks.

Objectives:
Clarify the factors that affect climate and cause it to change.

When a volcano erupts it

throws out large volumes of
Sulphur dioxide (SO2), water
vapor, dust, and ash into the

atmosphere

Ocean current

The oceans are a major

component of the

climate system. Ocean

currents move vast

amounts of heat across the

planet.

Natural Factors

Earth orbital changes

The earth makes one full orbit around the

sun each year. It is tilted at an angle of
23.5 to the perpendicular plane of its

orbital path. Changes in the tilt of the earth

can lead to small but climatically

important changes in the strength of the

seasons.

reflection of radiant energy back

toward the earth.

Effects of Climate change
Melting Of Glacier

Nearly 97% of Greenland's

surface ice sheet thawed during
a four day period in July - more
than it ever has in the last 30

years, NASA satellite data

shows.

Effects of Climate change
Melting Of Glacier

The disappearance of glaciers means less water

for consumption by the population, a lower

hydroelectric energy generation capacity, and less

water available for irrigation.

Effects of Climate change
Acid Rain

Acid rain is a rain or any other form of
precipitation that is unusually acidic.
Acid rain is caused by emissions of
sulfur dioxide and nitrogen oxides,
which react with the water molecules
in the atmosphere to produce acids.

Objectives:
Discuss the effects of climate changes on Earth..

/LISUAE

From your knowledge of the

composition of the acid rain, predict
how it may affects the living things.

Objectives:
Discuss the effects of climate changes on Earth..

TOGETHER FOR A BETTER FUTURE FOR OUR CHILDREN

/LISUAE

Acid rain makes water more acidic,

which results in more aluminum

absorption from soil, which is carried

into lakes and streams. That

combination makes waters toxic to

crayfish, clams, fish, and other aquatic

animals

Discuss the effects of climate changes on Earth..

Effects of CFC on the environment

Gaseous CFCs can deplete the ozone
layer when they slowly rise into the

stratosphere, are broken down by strong

ultraviolet radiation, release chlorine atoms,

and then react with ozone molecules.

Objectives:
Suggest ways to reduce the effects of climate change on
Earth.

Reduce deforestation

Deforestation

is when

forests are converted for
other purposes by cutting

down the trees to clear
the land for other use.
