3.  Global Warming is the increase of
Earth's average surface temperature
due to effect of greenhouse gases,
such as carbon dioxide emissions from
burning fossil fuels or from
deforestation, which trap heat that
would otherwise escape from Earth.

4.  Most climate scientists agree the
main cause of the current global
warming trend is human
expansion of the "greenhouse
effect“ warming that results
when the atmosphere traps heat
radiating from Earth toward
space.

5.  The greenhouse effect is the process by which
radiation from a planet's atmosphere warms
the planet's surface to a temperature above
what it would be in the absence of its
atmosphere.

7.  Ice is melting worldwide, especially at the Earth’s poles.
 Sea level rise became faster over the last century.
 Some butterflies, foxes, and alpine plants have moved farther
north or to higher, cooler areas.
 Precipitation (rain and snowfall) has increased across the globe,
on average
Some impacts from increasing temperatures are already
happening:

9. Other effects could happen later this century, if warming
continues:
 Sea levels are expected to rise between 7 and 23 inches (18 and 59
centimeters) by the end of the century.
 Hurricanes and other storms are likely to become stronger.
 Floods and droughts will become more common.
 Less fresh water will be available.
 Some diseases will spread, such as malaria carried by mosquitoes.
 Ecosystems will change, some species will move farther north or
become more successful; others won’t be able to move and could
become extinct.

11. Global warming impacts on species in a number of ways. Animals and
plants that are suited to cooler climates will need to move polewards or
uphill when the climate becomes even just that little bit warmer. The
impacts on species are becoming so significant that their
movements can be used as on indicator of a warming world.
They are the silent witnesses of the rapid changes being inflicted
on the Earth.

12. The polar bear could
disappear in the wild
unless the pace of
global warming
slows.

13. Sea turtles lay their eggs on Brazilian
beaches, many of which are threatened
by rising sea levels.

14. The North Atlantic whale is one of
the most endangered of all large
whales, with a long history of
human exploitation.

15. The giant
panda's future
remains
uncertain due
to a number of
threats.

16. Asia’s only ape – the orangutan – is in deep trouble.
Its last remaining strongholds in the rainforests of
Indonesia are being threatened by a range of
pressures, including climate change, putting the
animal at risk of extinction within a few decades.

17. In Africa, elephants face a range of threats
including shrinking living space, which brings
them more frequently into conflict with people.

18. Climate change is affecting home range,
abundance and breeding cycles of many of
Australia’s frog species.

19. Experts estimate
there are as few as
3,200 tigers left in
the wild, due to
poaching, the loss
of their habitat
and depletion of
the tiger’s natural
prey.

21.  The problem of global warming must be solved as soon
as possible because it is affecting the life of every
creature on earth, and if the earth keeps warming at
this rate, there will be no more life on our planet.
