thuyết trình Global warming

Global warming is the rise in the average temperature of the earth due to the increase of greenhouse gases like carbon dioxide, carbon monoxide, methane and others in the atmosphere.More extreme heat waves during the summer; Less extreme cold spells during the winterMany country like India or parts of Africa are very hot because of the heat from Greenhouse effect

Our Planet is having a serious problem !

Global warming has become perhaps the most complicated issue facing world

nowaday

the earth due to the increase

of greenhouse gases like

carbon dioxide, carbon

monoxide, methane and

others in the atmosphere.

2 What causes Global Warming?

INCREASE IN USAGE OF

CHEMICAL FERTILIZERS

ON CROP LANDS

DEFORESTATION FOR FARMLAND, WOOD, PAPER

3 Effect of global warming

More extreme heat

waves during the

summer; Less

extreme cold spells

during the winter

Many country like India or parts of Africa are

very hot because of the heat from

Greenhouse effect

*Ice Melting

A huge iceberg breaks off the Antarctic peninsula The Antarctic ice sheet holds 70 per cent of the

world's fresh water

1 - 2 mm/year over the past 100 years

Many Species Die due to the changing of sea level…

*Extreme weather

4 SOLUTIONS • Government

• Citizens

* Reduce the use of plastic bags → as burning plastic emit CH4

* Reduce the use of use of air-conditioner,

which will emit CFCs

* Use public transportation instead of private cars → reduce the pollutants emitted by cars

Our thoughts

Global Warming is a serious problem facing us; we need to help, decrease the pollution and improve the environment after all We do it not only to save

ourselves, but also to save the Earth, the humanity…
