What is climate change?
Climate change refers to any significant
change in the average weather conditions
of a given area or region lasting for an
extended period of time. (Environmental
Protection Agency , 2016)
*major shifts in global temperature,
precipitation, winds, or extreme
weather that occur over long term.
Signs that climate change exists:
 Higher temperatures
 Warmer oceans
 La Niňa (Floods)
 Increased ocean salinity
 Melting glaciers
 El Niňo (More droughts)
 Extreme weather
 Shrinking sea ice
 Rising sea levels
 Changing rain and snow patterns
Consequences of Climate Change:
 Crop losses
 Increased air pollution
 Increased species extinctions
 Increases spread of disease
 Increase power shortages, blackouts and demand
 Disappearing habitats and ecosystems
 Public water and reservoirs shortages
El Niňo
-is an abnormal
and lengthy warming in
the eastern part of the
Pacific Ocean.
-caused by the weak trade wind moving from
east to west collecting and piling up warm
surface water blocking the upwelling of colder
water which leads to El Niňo phenomenon.
La Niňa
-is triggered by the
strong wind trade from
the east Pacific ocean.
- trade winds that move from east to west are
strengthen resulting to intensified upwelling of
cold water bringing massive amounts of water
vapors.

What is global warming?
Global warming
- is a gradual,
long-term increase
in the average
temperature of
Earth's atmosphere.

Greenhouse Effect
- is the process by which radiation from
the sun is absorbed by greenhouse gases and not
reflected back into space.

Greenhouse gases
-trap some of the Earth's outgoing energy, thus retaining
heat in the atmosphere.
Enhanced Greenhouse Effect
-refers to the additional radiative heat resulting from
increased concentrations of greenhouse gases
induced by human activities.

FUELS
•Burning coal, oil and
gas produces carbon dioxide
and nitrous oxide.
• Fluorinated gases are emitted from
equipment and products that use these gases.
Such emissions have a very strong warming
effect, up to 23 000 times greater than CO2
•Cutting down forests
(deforestation). Trees help to regulate the
climate by absorbing CO2 from the atmosphere.
.
•Fertilizers containing nitrogen produce nitrous
oxide emissions.
•Increasing livestock farming. Cows and
sheep produce large amounts of methane
when they digest their food.
