Climatic Phenomena
That Occur On a
Global Level
QUARTER 3 – WEEK 5
Earth is a dynamic planet that has
constantly been changing. Weather events
and climate are a remarkable part of that
change. These changes are necessary for
our world to sustain life but sometimes,
these changes can also cause significant
harm and may cost a substantial amount in
restoration and recovery.
There are a lot of factors that contribute
to Earth’s climate however; recently
scientists have observed uncommon
changes in Earth’s climate. Scientists
agree that the Earth’s average
temperature has been increasing much
more rapidly in the past 50 to 100 years
due to human activities.
Difference between Climate Change and Global Warming
Greenhouse effect - one of the
major
causes
of
climate
change,
it
is
.
a process that occurs when gases in
Earth’s atmosphere trap the sun’s
heat.
Some of the Greenhouse gases
that
served
as
contributing
.
factors to climate change
1. Carbon dioxide (CO2):
This is the most recognizable culprit. It's a
.
gas
released through natural occurrences
— like volcanic activity — but also human
activities including deforestation and
burning fossil fuels. Significant carbon is
released through these actions. NASA
refers to CO2 as the most important longlived "forcing" of climate change.
2. Methane:
This is a hydrocarbon gas, less abundant
in the atmosphere than CO2. Methane is
produced through landfill
decomposition, agriculture, livestock,
and more.
3. Water vapor:
it’s the most abundant
greenhouse gas. And
keeps increasing as the
atmosphere warms.
With water vapor come
more clouds and
precipitation.
4.Chlorofluorocarbon
s (CFCS)
5. Nitrous oxide
Causes of Climate Change
Impacts of Climate Change
• Extreme Changes in Weather.
The sudden change in the climate
causes the weather to become extreme.
Droughts, heavy rain or violent storms are
some of the common results of extreme
weather.
• Threats to Flora and Fauna and Their
Habitat.
The plants and animals in the warmer
areas are on the edge of extinction
because of the changes in
temperature and climate.
• Ocean Acidification
Oceans become more
acidic because of the
excess carbon dioxide in
the atmosphere. The
Acidic Ocean makes it
hard for marine creatures
to survive.
• Declining of Ice
Sheets
The Antarctic and
Greenland ice
sheets are
decreasing in mass
at a very fast rate.
• Rising Sea Level
The water that comes from
the melting ice goes into the
oceans. The rising water
levels caused flooding.
Scientists warn that if global
warming continues
relentlessly, many low-lying
areas could sink.
To lessen the effect of climate change,
we have to reduce global warming.
This means we have to reduce the
production of carbon dioxide emission
and to use energy more efficiently.
.
These are some ways you can do to stop
and ease the effect of global warming:
• Use energy saving lights.
• Turn off electrical equipment when not
in use.
• Plant trees. Trees absorb carbon dioxide
and produce oxygen.
• Use public transport when going to
school, market or church or you can
walk to nearby places.
• Reduce, reuse and recycle. These
will help reduce the greenhouse gases
and save the natural resources.
