Climate Change:- Climate change is a long term alteration in.

Global weather patterns, Australian temperatures have, on average, risen byabout 1C with an increase in the frequency of heat waves and a decreasein the numbers of frosts and cold days.

Rainfall patterns have also changed Northwest has seen an increase inrainfall while much of eastern Australia and the far southwest have

experienced a decline

Why is climate changehappening?Gases in the earths atmosphere act like a blanket

surrounding.

earth or like a greenhouse trapp the suns heat and stoppingit from escaping.

Gases are called greenhouse gases and keep the earth at a

nice temperature.

Global Warming and GreenhouseEffect:-

: -ause 1 arbon dioxide emissions inillion tons per year over the last 200years .:-ause 2 oncentration of carbonioxide has dramatically increased

n the . ast 50 years


6/13

:-ffects of global warming:There are two major effects of global warming

-1 ( . ) .Increase of temperature on the earth by about 3 to 5 C 5 4 to 9 Fahrenheit by the year 2100-2 ( ) .Rise of sea levels by at least 25 meters 82 feet by the year 2100

Global Warming and GreenhouseEffect:-


7/13

Did you know?1. Did you know that without a natural greenhouse effect, the temperature of

the Earth would be about 0F (-18C).

1. Human activity has increased the concentration of greenhouse gases in the atmosphere

contributing to global warming.

Main greenhouse gases responsible for this are carbon dioxide (CO2), methane andnitrous oxide and the CO2,

UK in particular, is emitted by everyday activities like driving your car, heating yourhome and even switching on a light

2. Did you know that over 7 billion tones of CO2 is released in to the earths

atmosphere every year through using fossil fuels like oil, coal and gas. All gases stay in the atmosphere for a certain length of time, for CO2 this is between 50

- 200 years.

This means that CO2 will be present in the atmosphere for at least 50 years before it isabsorbed.

It also means that CO2 emitted into the atmosphere today could cause global warmingfor up to two centuries to come.

Carbon Footprint:-

:A carbon footprint is defined asThe total amount of greenhouse gases produced to

,directly and indirectly support human activities

usually expressed in equivalent tons of carbon(dioxide C )o2 .

Carbon Footprint:-
