4000 islands in Indonesia will drown in the upcoming years due to rising sea levels caused by global warming. Global warming refers to the increasing temperature of the earth's surface due to excess heat trapped in the atmosphere by greenhouse gases like carbon dioxide and methane produced by human activities. This enhanced greenhouse effect makes the earth's atmosphere thicker and prevents sun rays from escaping, causing the earth to get too hot.

3. What is Global Warming?
Global Warming refers to the increasing temperature of
earth's surface due to the excess heat trapped into our
atmosphere. This takes place due to enhanced green house
effect.

4. What is Greenhouse effect?
The phenomenon whereby the earth's atmosphere traps
solar radiation, caused by the presence in the atmosphere
of gases such as carbon dioxide and methane that allow
incoming sunlight to pass through but absorb heat radiated
back from the earth's surface. This keeps the Earth warm
and a nice place to live in, keeping us all happy.

5. “Enhanced” greenhouse effect
These days, human activities produce too much greenhouse gases
that makes the earth’s atmosphere thicker, making it impossible for
the Sun rays to reflect back into the atmosphere. Hence, the Sun rays
get stuck into the earth's atmosphere, making it too hot to live in. This
is called Enhanced Greenhouse Effect and is what's
causing Global Warming.

6. Greenhouse Gases
- Carbon-dioxide
- Methane
- Nitrous Oxide
- Chlorofluorocarbons
- Surface Ozone

7. Carbon Dioxide
- Produced by burning fossil fuels such as
gas, petrol, aviation petrol, diesel and oil#MesueseAurela

8. Methane
- Produced when you burp.
- Twenty –one times more effective
than carbon dioxide in blocking the
escape of radiant heat.

9. Nitrous Oxide
- Produced from burning forests, car
exhaust, jet fuel and artificial fertilizers.

10. Chlorofluorocarbons (CFCs)
- Invented in 1920s.
- Were found in aerosol spray cans and as coolant gases on refrigerators.
- Non-poisonous.
- Odourless.
- Were once called ‘wonder chemicals’.
- Stable and cheap to produce.

11. Surface Ozone
- Generated as a part of photochemical smog.
- Produced by the action of sunlight on motor vehicle and industrial pollution.

14. Evidence of global warming
#2- Icebergs are breaking off.

15. Evidence of global warming
#3- Ice sheet in Greenland is getting thinner.

16. Evidence of global warming
#4- Coral reefs in the Caribbean are now permanently bleached.

17. Evidence of global warming
#5- Alpine plant species has fallen.

18. Evidence of global warming
#6- Snowgums in Australia have shifted 40 meters up the mountain.

19. El Niño effect
El Niño effect occurs in which trade winds weaken or
reverse, allowing warmer water to move towards the
west coast of South America around Christmas time.
The result is that Australia experiences drought, and
South America experiences increased rainfall.
