Climate Change and The Energy Crisis
Climate Change and The Energy Crisis
“There is no question that climate change is happening;
the only arguable point is what part humans are playing
in it.”

Climate Change and The Energy Crisis
EMISSION OF GREENHOUSE GASES
Climate Change and The Energy Crisis
CLIMATE CHANGE is the global phenomenon of climate
transformation characterized by the changes in the
usual climate of the planet that are especially caused by
human activities.
- is the range of global phenomena caused by burning
fossil fuels that add heat-trapping gases to the Earth’s
atmosphere.
Climate Change and The Energy Crisis
CLIMATE CHANGE is both natural and anthropogenic.
The rising temperature is only caused by human
activities.
Climate Change and The Energy Crisis
GLOBAL WARMING it is generally defined as the general
warming effect caused by greenhouse gases in the
atmosphere.
Climate Change and The Energy Crisis
The greenhouse gases absorb infrared radiation that
enters the atmosphere and radiate it to the Earth’s
surface as heat, thereby warming the Earth.
Climate Change and The Energy Crisis
Some common greenhouse gases that contribute to
global warming include naturally occurring gases such
as carbon dioxide (CO2), methane (CH4), and nitrous
oxides (NOx), and man-made gases such as
chlorofluorocarbons (CFCs), hydrofluorocarbons, (HFCs),
perfluorocarbons (PFCs), and sulfur hexafluoride (SF6).
Climate Change and The Energy Crisis
GLOBAL WARMING
Keeps the planet warm and prevents warm air from
leaving the planet.
Climate Change and The Energy Crisis
DEFORESTATION is also pointed at as a culprit to this
adverse phenomenon. When forest land is destroyed, CO2
is released into the air, thus increasing the levels of long-
wave radiation and trapped heat. Deforestation also
affects biodiversity because damage in the rainforest
results in the destruction of wildlife habitats.
Climate Change and The Energy Crisis
Deforestation is one of the main causes of excessive CO₂
that is released in the atmosphere. It also affects the
biodiversity of rainforests.
Climate Change and The Energy Crisis
EFFECTS OF CLIMATE CHANGE
Melting of ice caps in the polar regions of the Earth that
causes dilution of salt in the ocean and disruption of
natural ocean currents.
Chapter 12 - climate change and the energy crisis
Climate Change and The Energy Crisis
Climate Change and The Energy Crisis
EFFECTS OF CLIMATE CHANGE
Polar bears are also decreasing in number because the
melting of the polar ice caps has caused them to starve
and lose habitats.
Climate Change and The Energy Crisis
EFFECTS OF CLIMATE CHANGE
Melting ice caps can also cause sea levels to rise which
may greatly affect low-lying coastal areas where large
populations dwell.
Climate Change and The Energy Crisis
Acid Deposition
When SO2 and NO2 react with particulate matters (dry) or
with water vapor (wet), acid deposition occurs which
causes surface water acidification and affects soil
chemistry.
Climate Change and The Energy Crisis
Acid Deposition
At pH levels lower than 5, acid deposition may affect the
fertilization of fish eggs, and can kill adult fishes. As
lakes and rivers become highly acidic, biodiversity is
reduced.
Climate Change and The Energy Crisis
Thermal Inversion
The major component of photochemical smog,
peroxylacetyl nitrate (PAN), is a combination of different
criteria pollutants, PAN is a transporter of NOx intro rural
regions and causes ozone formation in the global
troposphere, which can decrease visibility especially in
elevated places.
Climate Change and The Energy Crisis
Thermal Inversion
The pollutants that come from sources (i.e., industrial
chimney or stack) mix with air. The mixed air normally
rises to the atmosphere. In a normal cycle of thermal
inversion, an unstable air mass and air constantly flow
between warm and cool areas.
Climate Change and The Energy Crisis
Thermal Inversion
Thermal inversion is also affected by weather conditions,
or it may also occur in some coastal areas because of the
upwelling of cold water that lowers surface air
temperature.
Climate Change and The Energy Crisis
Thermal Inversion
Topography or man-made barriers like high-rise
buildings can also create a temperature inversion. The
cold air may be blocked by these barriers and then
pushed under the warmer air rising from the source,
thus creating the inversion.
Climate Change and The Energy Crisis
Thermal Inversion
Freezing rain or ice storms develop in some areas with a
temperature inversion in a cold area because snow melts
as it moves through the warm inversion layer.
Climate Change and The Energy Crisis
Thermal Inversion
El Niño is a normal climate pattern that describes the
unusual warming of surface waters in the eastern
tropical Pacific Ocean also known as the “warm phase”.
La Niña the “cool phase” which is a pattern that
describes the unusual cooling of the surface waters of the
region.
Climate Change and The Energy Crisis
Aside from the physical damages caused by disasters,
they also come with mental and emotional damage.
Victims of disasters may suffer from trauma, depression,
or anxiety because of experiencing loss caused by
disasters. This is why climate change should not be
perceived as an isolated issue—it affects may aspects of
human life.
