The greenhouse effect occurs when greenhouse gases like carbon dioxide, methane, nitrous oxide and water vapor in the atmosphere trap heat radiated from the Earth's surface, causing the average surface temperature to be warmer than it would be otherwise. The natural greenhouse effect helps maintain a temperature suitable for life on Earth, but human activities like burning fossil fuels have increased greenhouse gas levels and strengthened the effect, leading to global warming and climate change risks like rising sea levels and intensifying weather events. Reducing greenhouse gas emissions through choices in energy use, transportation, reducing waste and other individual actions can help mitigate the impacts.

2.  The greenhouse effect is a process by
which thermal radiation from a planetary
surface is absorbed by
atmospheric greenhouse gases, and is re-
radiated in all directions. Since part of
this re-radiation is back towards the
surface and the lower atmosphere, it
results in an elevation of the average
surface temperature above what it would
be in the absence of the gases.

3.  Nitrous Oxide. (N2O)
 Water Vapor. (H2O)
 Carbon Dioxide. (CO2)
 Methane. (CH4)

5.  Natural Green House Effect
is made from the heat
energy radiated from the
sun.
 Sunlight passes through the
atmosphere forming a cycle.
 The cycle continues as some
of the heat Green House
gases are naturally present.
 Sunlight passes through the
atmosphere gets trapped
and the leftover spreads in

6.  Activities done by man such as
deforestation, etc. result in increment of
Green House Effect.
 Greenhouse Effect also increases by burning
fuels in open.

7.  The greenhouse effect works like an
actual greenhouse, a place to keep
growing plants nice and warm.
 This is the same process that keeps
the Earth and the life on Earth nice
and warm.
 Visible light enters the top of the
Earths atmosphere, some of it is
scattered by air molecules and most
of it is reflected back into space.

8.  When the sun’s rays hit the Earth, 70
% of the energy stays on the planet,
absorbed by land, oceans, plants and
other things and the other 30%
reflects back into outer space by
clouds.
 But the 70% doesn’t stay on the
Earth forever, the things around the
planet that absorb the sun's heat
eventually radiate a portion of that
heat back out at a different
wavelength.

9.  This process keeps the Earth in radiative
equilibrium; the suns rays continuously
hitting the Earth warming it, and then
the warm Earth sends back the radiation
back into space cooling itself.
 Some of that released radiation makes it
into space, and the rest of it ends up
getting reflected back down to Earth
when it hits certain things in the
atmosphere, such as carbon dioxide,
methane gas and water vapor -- the car
windows. The heat that doesn't make it
out through Earth's atmosphere keeps
the planet warmer than it is in outer
space, because more energy is coming in
through the atmosphere than is going
out. This is the greenhouse effect that

10.  Rising temperatures cause water of the
oceans along with the sea to increase
 Increasing temperatures melt ice as it
starts to flow into the seas of Antarctica
and Greenland.
 Sea levels rise by 20-40 cm causing
tsunamis and floods in areas with low coast
areas e.g. Bangladesh and Netherland
 Flood in many areas cause danger for
living things

11.  Changes in the weather affect the growing crops around
the world.
 Crops of wheat and rice grow well in high temperatures.
 Sugarcane and maize don’t survive in high temperature
and end up dying.
 Furthermore change in the amount of rainfall affect the
growth leading to scarcity of food.
 South-Eastern part of the world will be

12.  Changes make it hard for humans to adjust
 and adapt to climate.
 Avoiding all the disasters moving from one
place to another will be hard.
 While weather and temperature changes,
the homes of plants and animals will be
affected .
 New homes for animals may not be safe

13.  Countries all over the world will be
affected
 Britain and Southeast will have a risk
of droughts
 Africa won’t have
enough water.

14.  Wasteful buying
- If you don't need or truly want
- something, don't buy it. It's going to end
up in the garbage.
 Turn off the lights when you leave the
room.
- Don't leave your television on while you go
to sleep. Only turn on the water tap when
you need it. For example, turn it off while
you
- are putting toothpaste on the toothbrush.

15.  Increasing in Greenhouse gases will change
weather around the world.
 North-western countries have an increase
of temperature .
 Summers will be hotter and winters would
be cooler
 Some places will become hotter and wetter
while some will be dry and cooler.
 The world will change with droughts,
 storms, floods, etc.

16.  Reduce, reuse and recycle.
- Reduce the things that your needs.
- Reuse items that you, have until they
are good for nothing. Recycle all that is
possible.
 Choose natural gas over coal and oil
every chance you get.
- For example ; when barbecuing.
 Get a hybrid or an electric car when
shopping for that new car.
- If this isn't possible, choose a small car
that gets good gas mileage.

17.  Form an environmental club in your high
school , college or community.
 Walk to places or get there by bike.
- It will improve your health and the health
of your planet.
 Get involved in tree planting projects.
