Evidence of Global
Warming

friend wether he likes it or not (; . <3
Global Warming And Climate Change


Burning coal, oil and natural gas
releases carbon dioxide gas into the
atmosphere. On average, this may
warm the earth and change the
climate in other ways. For example, it
might change the severity and
duration of storms or droughts.
Other human activities, such as
cutting down forests, and growing
rice, and raising cattle, may have the
same effect, but are less important
Greenhouse Gases
atmosphere that absorbs and emits
radiation within the thermal infrared
range.This process is the fundamental cause
of the greenhouse effect.The primary
greenhouse gases in the Earth's atmosphere
are water vapor, carbon dioxide, methane,
nitrous oxide, and ozone.
The atmosphere has a natural
supply of "greenhouse gases." They
capture heat and keep the surface
of the Earth warm enough for us to
live on. Without the greenhouse
effect, the planet would be an
uninhabitable, frozen wasteland.
Greenhouse Effect





Energy from the sun drives the
earth’s weather and climate, and
heats the earth’s surface;
In turn, the earth radiates energy
back into space;
Some atmospheric gases (water
vapor, carbon dioxide, and other
gases) trap some of the outgoing
energy, retaining heat somewhat
like the glass panels of a
greenhouse;
These gases are therefore known
as greenhouse gases;
The greenhouse effect is the rise in
temperature on Earth as certain
gases in the atmosphere trap
energy.
World Climate History

There are so many
different climates in
different time zones ,
different centuries .
That’s what’s so
amazing about the
world we live in , it
would only be WEIRD
if the climate was the
same all day
everyday. I listed so
you can see the
different times
scientist noted down
the weird drastic
climate changes for
the past hundreds
maybe even
thousands of years

World Carbon Dioxide History (chart)

The concentration of carbon dioxide in Earth's atmosphere is approximately
390parts per million by volume as of 2010 and rose by 1.9 during 20002009.Carbon dioxide is "essential to photosynthesis" in plants and other
pictures, and is also the same as greenhouse gas
Projected Climate Change due to
Global Warming


The climate is changing. The earth is
warming up, and there is now
overwhelming scientific consensus
that it is happening, and humaninduced. With global warming on the
increase and species and their
habitats on the decrease, chances for
ecosystems to adapt naturally are
diminishing.
Many are agreed that climate change
may be one of the greatest threats
facing the planet. Recent years show
increasing temperatures in various
regions, and/or increasing extremities
in weather patterns.
Melting of glaciers
Most of the mountain glaciers on
our planet that have been
monitored for the past 150 years
are reportedly shrinking. The
glaciers most affected by global
warming those located in the
lower latitudes and many of them
are disappearing. If glaciers
continue to shrink, it could affect
water supply in areas that depend
heavily upon mountain
watersheds
North Pole Changes


When the temapture or climate changes the ice for the polar bears go under water :o
The North Pole is located in the middle of the Arctic Ocean which constantly covered with
shifting sea ice. The North Pole latitude is 90° North. At the North Pole all lines of
longitude converge there, so North Pole longitude can be defined as any degree value.
Greenland is the closest land to geographic north pole
Glaciers of the World

All Glaciers Are Beautiful Sights , Even though you've
probably never seen a glacier, they are a big item when we
talk about the world's water supply. Almost 10 percent of the
world's land mass is currently covered with glaciers, mostly
in places like Greenland and Antarctica. Glaciers are
important features in the hydrologic cycle and affect the
volume, variability, and water quality of runoff in areas
where they occur. Example of a before and after glacier.
Greenland Changes

Climate change and global warming are hot topics of discussion all
over the world, and these discussions are particularly relevant in
relation to Greenland as the ice sheet is often mentioned in
connection with the debates on increases in global temperature.
Frozen fresh water is bound in the form of millions of cubic metres of
ice in Greenland, and overall the country contains 10%of the world's
total reserves of fresh water.
Ocean Level Changes
Pollution
As the number of active landfills dwindles and
coastal populations grow, offshore waste dumping
and coastal pollution increase. This additional
dumping increases the possibility of improper
waste disposal polluting the coastal environment.


Animals facing extinction due to
Climate Change
Because of humans, an alarming rate of animals are becoming extinct
every day. At this rate, more than half of the world's species will be
extinct in 100 years. The colour of the environment is changing – becoming bluer
– apparently due to climate change, says a new study that finds that environment
and animal populations are fluctuating more rapidly over time. Polo bears are
loosing there ice so thats whats affecting them. So is nemo ;O
Can we stop global warming?

OFCOURSE ! there's
many ways of stopping global
warming just that most humans don’t
do ish about it . There electrical cars ,
stop using hairspray outside an open
air environment.




Avoid high gas prices and carbon
emissions
Eat fresh, local foods for a healthy
environment and you
Learn how to reduce your home’s carbon
footprint
Keep money in your pocket and carbon out
of the air
