306_21_Tan Nichelle Climate Change
What is
climate change?
refers to changes in weather in a long period of time
increase in temperature
caused by
burning of fossil fuels which results in greenhouse gases
clearing of forests for buildings and agriculture releases huge amounts of greenhouse gases
impacts
of climate change
rise in sea level
as a
low lying country
,rise in sea levels is a threat towards singapore as about
30%
of our island is below 5 metres
water resources
if there is an
increase in intensity of weather
, periods of drought can affect the reliability of Singapore's water supply while sudden intense rainfall overwhelm drainage systems and thus leads to
flash flood
s.
biodiversity and greenery
could affect the
natural diversity of plants and animals
due to
the alteration of the ecosystems natural process such as soil formation, nutrient storage and pollution absorption
effect on public health
Singapore is situated where vector borne diseases like dengue are endemic. these diseases are observed during the
warmer periods of the year
. the sudden increase in temperature may also lead to more occurrences of heat stress and discomfort around sick and elderly
urban heat island effect
urban areas tend to be warmer thus leads to
heat stress
as well as greater use of air conditioning, increasing Singapore's energy demands and thus results in
higher domestic carbon emission
food security
a small increase in temperature could affect crops growing in other countries and ours eventually as we import more than
90%
of our food
what can we do about climate change
individuals role
use a
fan
to keep cool instead of air conditioners, also allowing you to
save $555
a year.
when using air conditioner, keep it at
25 degrees and above
. for every degree increased, you can save $20 a year
switch off appliances when
not in use
. switching it off can save you an
additional $45
a year
change to
energy efficient light bulbs
purchase energy efficient appliances such as those with
4 ticks
.
take
public transport
or
carpool
to reduce carbon footprint or switch to a
electric
or
hybrid
vehicle to
reduce carbon dioxide emissions
look for
water efficiency labels
when buying water devices. the more ticks, the more water and energy you can
you can also spread the word to
friends and relatives
and
encourage
them to be environmentally friendly and do the right thing.
governments role
build buildings with
environmentally friendly features
so it is cooler and more energy efficient.
the
national biodiversity strategy action plan
was launched by Nparks to promote its n
ature conservation
efforts. they safeguard Singapore's biodiversity and conserve Singapore's habitats and these actions can help absorb and store carbon dioxide.
local water catchments will expand and singapore will further develop alternative sources such as
seawater desalination
and
NEWater
. Others also include
variable salinity plant technology
. This will thus ensure a sustainable water supply for population and industry.
the
NEA
has implemented an integrated, evidence based dengue control program consisting of a
mosquito surveillance
and control
,
enforcement,**research,
community outreach
and
public education
to reduce dengue transmission in Singapore.
measures such as energy pricing based on
market principles
,
information on energy use and costs
through schemes and
mandatory labeling
, habit of energy efficient practices, promoting energy efficient designs and encouraging the use of
public transport
will be implemented to improve Singapore energy intensity by
35%
from 2005 to 2030
