3.  Signs of global warming
 Causes of global warming
 Green house effect
 Human activities
 Effect of climate change
 Effects on bio life
 Effect on ozone layer
 Controls of global warming

4.  Arctic sea ice extent is diminishing.
 Ocean heat content is increasing.
 Air temperature over ocean is increasing.
 Sea surface temperature is increasing.
 Global sea level is rising.
 Humidity is increasing.
 Temperature of the lower atmosphere is increasing.
 Air temperature over land is increasing.

5.  Green house effect
 Human activities

6.  The greenhouse effect is the process through which heat
is trapped near Earth's surface by substances known
as 'greenhouse gases
 Some of the Green house gases are:
1. Carbon dioxide (CO2)
2. Methane (CH4)
3. Nitrous oxide (N2O)
4. Hydro fluorocarbons (HFCs)
5. Per fluoro carbons (PFCs)
6. Sulphur hexafluoride (SF6)
7. Nitrogen tri fluoride (NF3)

7.  Deforestation
 Burning fossil fuels
such as
1. Coal
2. petroleum
3. Gasoline
4. Natural oils
5. Tar sands
 Industrial
resolution

8.  Power building
 Generating power using fossil fuels
 consuming too much
 Mining activities

9.  Droughts
 Wild life
 Floods
 Storms
 Hurricanes
 Heat weaves

10.  Heavy precipitation
 Disappearing of glaciers
 Rise in sea level
 Disruption in habitats
 Increase in ocean temperature

12.  Air pollution and water pollutions causing
1. Allergies
2. Asthmas
3. Infections
 Increase in death toll of humans
 Water shortage
 Poverty

13.  Extinction of plant
 Extinction of marine species
 Loss to coastal eco system
 No enough food for consumption

14.  Depletion of ozone layer leads to radiation reach to
earth
1. skin cancer,
2. cataracts
3. impaired immune systems

15.  Large scale government action
 Conserving energy
 Buying electrical appliances with star label
 Purchasing cars having high mileage with less
emissions
 Using public transport
 Aim is to limit global warming to 1.5degree celcius by
2040
