2. According to PAGASA's climatological data, the hottest
weather in the Philippines, is experienced every April and May.
The hottest day in the history of Metro Manila was on May
14, 1987, when the temperature reached 38.5°C, while the
hottest day in the Philippines was recorded on April 22, 1912
and May 11, 1969 in Tuguegarao, Cagayan Valley. On both of
these dates, the temperature in Tuguegarao reached 42.2°C.
The hottest day in the world was reported on July 10, 1913 in
Death Valley in California, USA, where the temperature shot
to 56.7°C.
Direct Impacts on Temperature

3. During normal conditions, trade winds (easterly
winds), generally blow equatorial waters
westward from the eastern Pacific to the
western Pacific or toward the coast of
equatorial Asia and Australia. These warm up
because of the waters' exposure to the sun.
Extreme Weather
Extreme episodes of El Niño and La Niña are two
effects of climate change. Both phenomena are
influenced by the surface temperature in the
equatorial Pacific Ocean.

4. Extreme Weather
El Niño
During El Niño, winds weaken, causing sea
surface temperatures to rise. The warm waters
are pushed eastward. El Niño can cause drought
in the western Pacific but trigger wet winters in
the eastern Pacific.
For our country, El Niño causes drier than
normal weather conditions. It can last for
one or more seasons.

5. Extreme Weather
During La Niña, the opposite of El Niño, cooler-
than-normal subsurface where accumulates in
the central equatorial Pacific. Strong winds
moving toward the west push the cool ocean
waters toward South America. La Niña brings
more rains in western Pacific and reduces rainfall
in eastern Pacific. The cold temperature in the
eastern Pacific makes it difficult for rain clouds
to form.
La Niña
La Niña can bring above normal rainfall
over some parts of the country.

6. Earth's waters, which teem with life, are at risk of
pollution because of flood runoffs. Flood water
deposits wastes, silt, chemicals from agricultural
pesticides and fertilizers, and other pollutants into
the bodies of water. These pollutants can
adversely affect the aquatic food chain.
Furthermore, ice in polar regions can also melt,
resulting in the desalination of the oceans, which
has an effect on the patterns of ocean currents as
well as on different forms of marine life.
POOR WATER QUALITY AND
SCARCITY OF WATER

7. POOR WATER QUALITY AND
SCARCITY OF WATER
Increased temperatures can also lead to the excessive
evaporation of water. This can trigger extremely dry
weather in some areas and heavy precipitation in others.
The water supply in dry regions is not enough to support
economic activities such as farming, raising livestock, and
generating electricity among others. Excessive
precipitation, on the other hand, facilitates the transport
of sediments, animal wastes, and other pollutants into
water supplies requiring more intensive and mechanical
treatment in sewer systems bcomes necessary.

8. Low Soil Productivity
Drought and excessive precipitation can
reduce soil productivity. A lack of water
stunts the growth of crops. When
floodwaters erode soil, they can strip away
minerals vital to food crops.

9. Emergence of Climate-Sensitive
Diseases and Illnesses
The emergence of climate-sensitive
diseases and illnesses is a growing global
concern as climate change alters
environmental conditions, affecting
human health.
Climate-sensitive diseases are those
influenced by temperature, humidity,
extreme weather events, and ecosystem
disruptions.
The relationship between climate
change and the emergence of new
diseases is a complex and growing
concern.
As global temperatures rise, weather
patterns shift, and ecosystems change,
the conditions for infectious diseases to
spread are increasingly favorable.

10. When the body is exposed to extremely high temperatures and does
not get enough water for a prolonged period, it fails to regulate its
temperature and suffers heatstroke.
Heatstroke needs emergency care. If it's not
treated, heatstroke can quickly damage the brain,
heart, kidneys and muscles. This damage gets
worse the longer treatment is delayed, which
increases the risk of serious complications or death.
Heatstroke

11. The condition may begin as simple heat cramps that can progress to fainting
and exhaustion. People over age 50 are vulnerable as are athletes training
under the heat of the sun.
First aid for heatstroke involves keeping the patient in a cool
place, removing unnecessary clothing, and applying ice packs
to the neck, underarms, and groin bring body temperature
down. Do these while waiting for medical help.
Heatstroke

12. Dengue
Dengue virus-bearing mosquitos favor areas
with warmer climates and more rainfall.
As the illness progresses, body temperature
may drop and tiny red spots may appear on
the skin.

13. Dengue Symptoms/Prevention
High fever that lasts for a week
Aching muscles and joints
General weakness
Pain in the eyes
As first aid, the Department of Health
recommends the DENGUE strategy:
Daily monitoring of the patient
Encourage intake of oral fluids
Note any dengue warning signs
Give paracetamol and not aspirin
Early consultation
Use mosquito nets
STOP
LOOK
LISTEN

14. To prevent dengue the DOH espouses the four o'clock
"STOP, LOOK, LISTEN" habit. Communities are encouraged
to stop whatever they are doing at 4 o'clock in the afternoon,
look for breeding sites of dengue-carrying mosquitos to
eliminate them, and listen to instructions from the authorities.
The patient should also avoid eating brown, red, or dark-
colored foods or drinks, which can turn the stool dark. Dark
stools can be mistaken from bloody stools, which is a sign of
abdominal bleeding, a common symptom among patients with
severe dengue.
Dengue Prevention

15. DIARRHEA refers to loose and frequent
bowel movement can lead to dehydration
if not addressed properly and inmediately.
This condition is caused by bacteria in
contaminated food or water. To treat
diarrhea, one can take antidiarrheal drugs
such as loperamide. The patient should
also drink plenty of fluids to prevent
dehydration.
WATERBORNE DISEASES
FLOODS can carry waterborne
diseases such as leptospiroses from
the urine of rats and various skin
diseases. Flood water can also
contaminate the municipal water
supply. Using and drinking
contaminated water can cause
diseases such as diarrhea.
LEPTOSPIROSIS is caused by the bacterium
Leptospira and affects both humans and animals. If
untreated, it can lead to kidney damage, meningitis,
and death. To avoid contracting the disease, people
must avoid walking in flood water. If walking in
flood water cannot be avoided, they should wear
boots and other protective gear, if possible. They
should also wash their feet and legs with soap and
water. Leptospirosis is treated with antibiotics sach
as doxycycline or penicillin.

16. Foodborne Disease
(foodborne illnesses or food poisoning)
are infections or intoxications caused by
consuming contaminated food or beverages.
They can result from bacteria, viruses,
parasites, or chemical substances.
• Viruses – Norovirus, Hepatitis A virus, Rotavirus
• Bacteria – Salmonella, Escherichia coli (E. coli), Listeria,
Clostridium botulinum, Campylobacter
• Parasites – Giardia, Toxoplasma gondii, Cryptosporidium
• Toxins & Chemicals – Mycotoxins from fungi, pesticides,
heavy metals (e.g., lead, mercury), natural toxins (e.g.,
in poisonous mushrooms, pufferfish)
Causes of Foodborne Diseases:
Symptoms of Foodborne Diseases
• Nausea and vomiting
• Diarrhea
• Abdominal pain and cramping
• Fever
• Weakness and fatigue
• Dehydration (severe cases)
Common Food Sources
• Raw or undercooked meat,
poultry, seafood, and eggs
• Unpasteurized dairy products
• Contaminated water
• Unwashed fruits and vegetables
• Improperly canned or preserved foods

17. When their habitat is at risk, organisms move out
a safer territory.
Because of flood, people in low-lying areas
are forced to evacuate.
Displacement of
Populations Due to Floods
and Natural Disasters

18. Climate Change
Addressing

19. Addressing Climate Change
Climate change is both an individual and a global responsibility.
Ironically, the countries that are most at risk of
the impacts of climate change are those that
produce the least amount of greenhouse gases. Why?
Because greenhouse
gases are keeping our
planet at a suitable
temperature for life. They
trap some of Earth's heat
energy so that it doesn't all
escape into space.
An environmental law called "polluter pays" aims to
ensure that the biggest polluters, such as countries that
produce large amounts of greenhouse gases, will bear
the cost of reducing and controlling greenhouse gas
emissions.

20. Addressing Climate Change
How can we
address climate
change to the
society?

21. Weather is the day-to-
day changes in the
atmosphere in a particular
place. It is the current
conditions in a specific
place and time.
Climate is the cumulative
pattern of weather in a
particular place over time.
It is the average
conditions in a specific
place over a long period
of time.
Carbon dioxide, one of
the major greenhouse
gases, traps the heat
from the sun in Earth's
atmosphere.
Global warming refers
to an increase in the
Earth's temperature,
which causes climate
change.
Ecological footprint
measures humanity's
use of resources against
Earth's capacity to
regenerate.
Climate change can lead to
the Emergence of
diseases, the displacement
of populations, extreme
weather, and low soil
productivity.
