2. Global warming is the process when the Earth heats up, and the
temperature rises. This happens when there is an increase in the production
of gases like carbon dioxide, water vapour, nitrous oxide and methane,
which are known as greenhouse gases.
•These greenhouse gases trap heat and light from the Sun in the earth’s
atmosphere and this is turn increases the temperature and causes global
warming.
•Basic principles of global warming first noted in 1827 by the French scientist
Jean Baptiste Fourier.

Drastic increase in earth’s surface atmospheric temperature.
Rise in sea levels
Melting of glaciers
Intensive hurricanes at coastal areas
Frequent rain falls/floods in some areas
Draughts in some areas due to high temperature
Decline in crop productivity leads to food shortage
Heat waves becomes common and causes further decline of
endangered species

Arctic sea ice melting at the rate of 9 % per decade.
Loss of mammoths on earth, which are the animals seen in the ice
ages.
Loss of coral reefs, sea flora and fauna leads to decline endangered
species.
Frequent natural calamities like draughts, hurricanes, tsunamis,
earth quakes, storms, typhoons etc., in some parts of the world.
Drastic temperature rise during 21st century over other centuries.
Increase of allergies due to increase content of dust, pollen in the air.
Increase in spread of mosquito borne diseases like malaria, dengue,
chikungunya in tropic regions.
Disappearance of islands due to rising sea levels (Indonesia has lost
24 of its islands)
Depletion of ozone layer in stratosphere in arctic region.
Disappearance of lakes (Over 125 lakes were lost in arctic area in last
few decades), 13 % decrease glaciers in Himalayas.

Increasing earth’s green sheet by social forestry.
Rationale use of natural resources.
Improving strategies of renewable energy sources.
Decreasing population density on earth.
Declining pollutants content in the environment.
Did you know?
Only 3 molecules of ozone/ 10 millions of air molecules
My Conclusion:
Global warming is a global warning for us.
