Global warming is the rise in the average temperature of Earth's atmosphere and
oceans since the late 19th century and its projected continuation. Since the early
20th century, Earth's mean surface temperature has increased by about 0.8 °C
(1.4 °F), with about two-thirds of the increase occurring since 1980.[2] Warming
of the climate system is unequivocal, and scientists are more than 90% certain
that it is primarily caused by increasing concentrations of greenhouse gases
produced by human activities such as the burning of fossil fuels and
deforestation.[3][4][5][6] These findings are recognized by the national science
academies of all major industrialized nations.[7][A]
Climate model projections were summarized in the 2007 Fourth Assessment
Report (AR4) by the Int
ergovernmental Panel on Climate Change (IPCC). They indicated that during the
21st century the global surface temperature is likely to rise a further 1.1 to 2.9 °C
(2 to 5.2 °F) for their lowest emissions scenario and 2.4 to 6.4 °C (4.3 to 11.5 °F)
for their highest.[8] The ranges of these estimates arise from the use of models
with differing sensitivity to greenhouse gas concentrations.[9][10]
According to AR4, warming and related changes will vary from region to region
around the globe.[11] The effects of an increase in global temperature include a
rise in sea levels and a change in the amount and pattern of precipitation, as well
a probable expansion of subtropical deserts.[12] Warming is expected to be
strongest in the Arctic and would be associated with the continuing retreat of
glaciers, permafrost and sea ice. Other likely effects of the warming include a
more frequent occurrence of extreme-weather events including heat waves,
droughts and heavy rainfall, ocean acidification and species extinctions due to
shifting temperature regimes. Effects significant to humans include the threat to
food security from decreasing crop yields and the loss of habitat from
inundation.[13][14]
Proposed policy responses to global warming include mitigation by emissions
reduction, adaptation to its effects, and possible future geoengineering. Most
countries are parties to the United Nations Framework Convention on Climate
Change (UNFCCC),[15] whose ultimate objective is to prevent dangerous
anthropogenic (i.e., human-induced) climate change.[16] Parties to the UNFCCC
have adopted a range of policies designed to reduce greenhouse gas
emissions[17]:10[18][19][20]:9 and to assist in adaptation to global
warming.[17]:13[20]:10[21][22] Parties to the UNFCCC have agreed that deep
cuts in emissions are required,[23] and that future global warming should be
limited to below 2.0 °C (3.6 °F) relative to the pre-industrial level.[23][B]
Reports published in 2011 by the United Nations Environment Programme[24]
and the International Energy Agency[25] suggest that efforts as of the early 21st
century to reduce emissions may be inadequate to meet the UNFCCC's 2 °C
target.

Global warming causes too many problems. A lot of people may have no place to live,
because of the raising of the sea level. Polar bears will be extinct in 45 years, because
of the melting of an ice layer. Even more and more people will die, because of the
lack of food. We have to keep our bad habits away like wasting water, electricity, and
any energy we don’t have to use. Then we can be heroes who safe the earth.

Global warming is surely a serious problem that we have to solve. But there's no any
effective solution to the problem and thus the problem is still keep worsening. But if
we escaped from facing the problem , we will never have a good environment again!

There is no doubt that global warming really bring a big trouble to us. Kenting
National Park is in south of Taiwan. With the problem getting worse and worse, there
aresome coral bleaching. Because of this, we can't see the awesome sceneries as
previously in Kenting anymore. So, we have to do something to improve the situation.
For instance, we can use public transportations instead of driving our cars. Moreover,
we have to turn off household appliance. However, we have only an earth, so we
have to be responsible for the problem.

Goobal warming is a big problem .If we ignore it, many countries will extinct and so
do many creatures,unsual weather happen.....I think the solution is use the public
transportations,eat less meat,recycle.We just have one earth, if we lost it ,it will never
come back. WE really have to protect our home!!

It's really terrible to hear the influences of global warming. For example, because the
heat of global warming will melt the icebergs, which lead to the rise of sea level, it may
let the beautiful coral reef island, Maldives, lose its territory. If we don't take actions,
the situation will become worse, not only Maldives but also Taiwan, our homeland, will
become the victim of this horrible calamity. To save people on Earth, it's about time for
us to do something.
