When the greenhouse gases
trap more heat in the Earth’s atmosphere, it causes average temperatures to
rise all over the world. For the last 30 years, temperatures have risen and it
was recorded that 2001 to 2010 was the warmest decade ever. As the Earth warms
up, heat waves occur causing more common region to experience very high
temperatures for several days and nights, including the Malaysia. Higher temperatures
mean that heat waves will happen more often and last longer and cause climate
change all over the world. This situation can be very dangerous, causing agriculture-
crop losses, the rise of energy consumption, affecting water resources, human health
and ecosystem.

Global climate change can
make it hard to grow certain crops due to the high temperature. In addition, droughts
caused by climate change could reduce the amount of water available for
irrigation. Climate change is can also cause extreme storms or floods, which
can damage the crops. Moreover, it also could change the rainfall patterns which
help some kinds of weeds and pests to spread to new areas.

Next, climate change literally
will affect how much we need energy and when we need it. As temperature rises, the
use of air conditioning will increase, which lead to a lot of electricity
consumption. Nevertheless, in colder places, they need less energy to heat
buildings because it may not get as cold as it used to be. Meanwhile, climate
change could also make it harder to produce hydropower as a source of
electricity.

Climate change also
affecting water supplies. Unfortunately, some parts of the world already have
very little water, and this climate change could make this problem worse. Rising
temperatures, changing raindrop patterns, and increasing droughts will affect
the amount of water in rivers, lakes, streams, and the amount of water that
seeps into the ground to replenish ground water.

Prolonged exposure to strong
heat wave can lead to heat exhaustion, heat cramp, heat stroke, and fatality as
well as any other chronic conditions or diseases. These serious health
consequences mostly affect the elderly, children, and those who have
cardiovascular and respiratory diseases. In socioeconomic point of view, people
with economically disadvantaged and socially isolated are also at risk to face
heat-related burdens. As global temperatures increasing and extreme heat phenomenon
increase in frequency due to climate change, we could expect more heat-related
illnesses and mortality in future.

Most plants and animals
live in areas with very specific temperature and rainfall patterns that enable
them to survive. This situation could affect the living plants and animals, as
well as the entire ecosystem survival. In order to survive, some species move
to the cooler locations which have higher elevations to find suitable places to
survive for example, in North America, animals and plants are moving farther
north. Moreover, as temperatures rise, many plants starting to grow and bloom sooner
in the spring and survive longer in the fall. This situation goes same for some
animals. They wake up from hibernation earlier or migrating at different times
too. This shows that climate change also affects the life cycles of plants and
animals all over the world.

Heat Transfer Application: Capturing Carbon Dioxide

 

The aim of carbon isolation is to collect
accumulated carbon dioxide in the atmosphere and keep it in a secured storage. Usually,
capturing carbon dioxide focus in concentrated sources like power plants. It is
because this is the most realistic method for large sources which initially
offers the most cost-effective avenue to isolation. In order to stabilize
atmospheric levels of carbon dioxide, every emission will need to be reduced
such as carbon dioxide release by vehicles and domestic.

 

            Without making the existing energy
or transportation infrastructure out dated, carbon dioxide extraction can decrease
the atmospheric carbon dioxide levels. Furthermore, pipelines network is not
needed to move the carbon dioxide from its source to its disposal site because
we only need the atmosphere which will be a temporary storage and transport
system.

           

The choice of sorbent must be carefully examined.
A good sorbent should not escape in large quantities from the capturing system,
and it should be environmentally benign. Moreover, a good sorbent needs to be extremely
cheap, or can withstand many recycle loop.

 

A major advantage of carbon capture from
the air is that it does not need abandonment of existing infrastructure.
Extraction of carbon dioxide from the atmosphere would allow the removal of carbon
dioxide virtually, instantly and it could be rapidly grown over the next few decades.
Moreover, the process cost is independent of the amount of consumption. We
could actually focus to reduce carbon dioxide in the atmosphere by capturing exceeding
the emissions. For example, Climeworks, a
company near Zurich, Switzerland, begin operations at a facility plans to
compress the carbon dioxide it extract and use it as fertilizer to grow crops
in greenhouses.

 

In conclusion, along with
cutting fossil fuel use to zero, removing carbon dioxide from the air is highly
seen as one way to stop the long-term buildup of greenhouse gases in the
atmosphere. Implementing the technology to extract carbon dioxide from the
atmosphere, such as planting new forests and building facilities can directly
remove and capture climate pollution from the atmosphere. This method has never
been tried at a large scale, but who knows if it can be used worldwide to
remove enough carbon dioxide to slow down the global warming.
