EFFECT OF GLOBAL WARMING
INCREASE IN TEMRATURE
INCREASE SEA LEVEL
It is a gradual increase in the
overall temperature of the earth’s
atmosphere generally attributed to
the greenhouse effect caused by
increased level of carbon dioxide ,
CFCs, and other pollution.
HERE ARE SOME NATURAL
CAUSES OF GLOBAL WARMING
CAUSES
NATURAL CALAMITIES
OZONE DEPLETION
GREEN HOUSEEFFECT
DEFORESTATION
The greenhouse effect is a natural process that
warms the Earth’s surface. When the Sun’s energy
reached the Earth’s atmosphere, some of it is
reflected back to
space and the
rest is
absorbed and
re-radiated.
 CARBON DIOXIDE
 METHANE
 OZONE
 WATER VAPOUR
 CFC’s
Deforestation ,clearance or clearing is the
removal of the forest or stand of trees where
the land is thereafter converted to a non-
forest use. Deforestation occurs for multiple
reasons: trees are cut down to be used for
building or sold as fuel [sometimes in the
form of charcoal or timber],while cleared
land is used as pasture for livestock and
plantation.
Ozone is constantly created and
destroyed, in the past 50 years, the rate
of destruction has far exceeded its rate of
creation. As a result a hole has appeared
over Antarctica in the ozone layer of that
atmosphere. The main destroyers of
ozone are cfc’s [chlorofluorocarbons].
Natural calamities
A natural disaster is a major adverse3 event
resulting from natural processes of the earth;
example include floods, hurricanes, tornadoes
volcanic eruptions, earthquake, tsunamis and
other geologic processes. A natural disaster can
cause loss of life or property damage, and
typically leaves some economic damage in its
wake, the severity of while.
Here are some anthropogenic
causes of global warming
RAPID POPULATION GROETH
MINING ACTIVITIES
INDUTRIALIZATION
Industrialization is the period of social and
economic change that transform a human
group from an agrarian society into an
industrial society , involving the extensive
re-organisation of an economic for the
purpose of manufacturing.
MINING EFFECT
The effect of mining includes
erosion formation of sinkholes, loss
of biodiversity, and surface water by
chemicals from mining processes.
POPULATION GROWTH
POPULATION GROWTH IS THE INCREASE IN THE NUMBER OF INDIVIDUALS IN A
POPULATION . GLOBAL HUMAN POPULATION. GROWTH AMOUNT TO AROUND 75
MILLION ANNUALLY , OR 1.1% PER YEAR . THE GLOBAL POPULATION HAS GROWTH
FROM 1 BILLION IN 1800 TO 7 BILLION IN 2012 . IT IS EXPECTED TO KEEP GROWING ,
AND ESTIMATES HAVE PUT THE TOTAL POPULATION AT 8.4 BILLION BY MID -2030,AND
9.6BILLION BY MID -2050 . MANY NATION WITH RAPID POPULATION GROWTH HAVE
LOW STANDARDS OF LIVING , WHEREAS MANY NATIONS WITH LOW RATES OF
POPULATION GROWTH HAVE HIGH STANDARDS OF LIVING.
Climate change will bring about
sustainable changes in cereal production
specially in the tropics . In the tropics ,
cereals dominate the food sources and
are the mainstay of agriculture . There
will be more shortages of cereals.
