Climate Change Flashcards
Climate change is
a long-term change in the
average weather patterns that have come to
define Earth’s local, regional and global
climates.
Climate change is a long-term shift in global or
regional climate patterns. Often climate change refers
specifically to from
the mid-20th century to present.
the rise in global temperatures
Climate change refers to long-term shifts in temperatures and weather patterns. Such shifts can be natural, due to ?. But since the
1800s, ? have been the main driver of climate
change.

Evidences (5)
Changing temperature and
precipitation patterns.
Increases in ocean temperatures,
sea level, and acidity.
Melting of glaciers and sea ice.
Changes in the frequency,
intensity, and
duration of extreme weather
events.
Shifts in ecosystem characteristics,
like the length of the growing season, timing of flower blooms, and
migration of birds.
The gases accumulated
in the atmosphere
prevent some of the heat
from radiating back out
into space and serve as a
thick enclosure that
causes the earth’s
temperature to rise
Greenhouse effect
It is the primary greenhouse gas contributing to
recent climate change.
Co2
enters the
atmosphere through burning fossil fuels, solid waste,
trees, and other biological materials, and because of
certain chemical reactions, such as cement
manufacturing.
Co2
absorbed and emitted naturally as part of the
carbon cycle, through plant and animal
respiration, volcanic eruptions, and ocean-
atmosphere exchange.
Co2
Both natural and human activities produce
Methane
For example, natural wetlands,
agricultural activities, and fossil fuel extraction and
transport all emit
Methane
It is produced mainly through agricultural
activities and natural biological processes.
Nitrous Oxide
Fossil
fuel burning and industrial processes also create
Nitrous Oxide
Chlorofluorocarbons,
hydrochlorofluorocarbons,
hydrofluorocarbons, perfluorocarbons, and
sulfur
hexafluoride, together called
F-gases,
are
often used in coolants, foaming agents, fire
extinguishers, solvents, pesticides, and
aerosol
propellants.
F gases
another greenhouse gas and plays a
key role in climate feedbacks because of its
heat-trapping ability.
Warer vapour
? air holds
more moisture than ? air.
Warmer, cooler
Therefore,
as greenhouse gas concentrations increase
and global temperatures
rise, the total amount of water vapor in the
atmosphere ?
also increases
Effects on humans (8)
sunburn
-blisters
-skin cancer
-heat stroke
-shortage of food
-malnutrition
-weaker immune system
- increase of diseases
Effects on Agriculture and
Environment (8)
-drought
-floods
-coral reef destruction
-sickness and death of plants and animals
-soil erosion
-change in animals’ migration pattern
-extinction
-storm surges and tsunamis
Effects on economy 3
(3) slow production
-business and livelihood
opportunities decline
-increase in prices
The Philippine Congress passed Republic Act?
or Local Climate Change Action Plan (LCCAP) in
2009. This led to the establishment of the ? which focuses on carrying
out programs to avert climate change.
9729, Climate
Change Commission
In 2012, RA9729 was amended by
? to further strengthen and
reinforce the programs and action plans
against climate change.
RA10174
The Climate
Change Act of 2009 was signed by then
? In?
President Benigno Aquino III in 2011.
In terms of international policies, during
the UN Climate Change Conference in
?, ministers from ? countries met
and moved for the adoption of the?
196 Paris
Agreement.
Look for ? on energy-
efficient products including appliances, lighting, cooling
and heating equipment, electronics, and office
equipment
Energy Star certification labels
Buy ? generated from renewable energy
sources like solar, wind, and hydropower.
green power
Reduce associated greenhouse gas emissions by
thinking about the environmental impact of products. For example, ?
consider a product’s durability, sustainability,
and ease of recycling when making a purchase.
? composting food
scraps, and donating unused food to food
banks or shelters.
Buying only what you need,
? is the single largest
category of material placed in municipal landfills,
where it emits ?, a powerful greenhouse gas.
Food methane
Reuse n repurpose items
Buy used items
Continue to use ? like
biking, walking, carpooling, and public
transportation.
