Global warming is caused by greenhouse gases like carbon dioxide trapping heat in the atmosphere. This is leading to more extreme weather like stronger hurricanes, heavier rainfall, and longer/hotter heat waves. Other effects include melting glaciers and rising sea levels, which threaten cities like Miami. Studies also show that climate change has increased the risk of Australian bushfires and warming is happening twice as fast in Canada as the rest of the world, especially in Arctic regions, with many changes now considered irreversible.

2. • How is global warming linked to extreme weather ?
• Global warming occurs when carbon dioxide (CO2) and other air
and greenhouse gases collect in the atmosphere and absorb sunlight
solar radiation that have bounced off the earth’s surface .
• How is global warming linked to extreme weather ?
• Scientists agree that the earth’s rising temperatures are fueling longer
hotter heat waves , more frequent droughts, heavier rainfall, and
powerful hurricanes .
• What are the other effects of global warming ?
• - Melting glaciers
• - Rising sea levels
• - Forests , farms , and cities will face troublesome new pests , heat
heavy downpours , and increased flooding . All those factors will
or destroy agriculture and fisheries .
• - Disruption of habitats

3. • Over the past 50 years, the
average global temperature
has increased at the fastest
rate in recorded history . And
experts see the trend is
accelerating . As a result of
this the sea level rises because
of the ice melting in the north
/ south pole .
Some cities like
Miami are just
above the sea level
and will be greatly
effected in the
near future . Miami
has parts that sit

5. HOW CLIMATE CHANGE
HAS EFFECTED
AUSTRALIA
Global warming has also inflicted climate
change . Global warming boosted the risk of
the hot, dry weather that's likely to cause
bushfires by at least 30%, they say.
But the study suggests the figure is likely to
be much greater.
It says that if global temperatures rise by 2C ,
as seems likely, such conditions would occur
at least four times more
often .We are all aware of the Australian bush
fires and how brutal they are , and by these
studies they will be more frequent if the
temperature increases . At least 33 people
were killed and more than 11 million hectares
(110,000 sq km or 27.2 million acres) of bush,
forest and parks across Australia burned .

6. HOW GLOBAL WAMING
EFFECTS CANADA
Canada is warming on average at a rate
twice as fast as the rest of the world, a
new scientific report indicates.
The federal government climate report
also warns that changes are already
in many parts of the country and are
projected to intensify.
Canada's Arctic has seen the deepest
and will continue to warm at more than
double the global rate.
The report suggests that many of the
already seen are probably irreversible.
Canada's annual average temperature has
warmed by an estimated 1.7C (3F) since
1948, when nationwide temperatures
first recorded.
The largest temperature increases have
seen in the North, the Prairies, and in
northern British Columbia.
