• Droughts • Diseases
• Hurricanes • Forest fires
• Floods • Air pollution
• Greenhouse effect • Global Warming
consequences

3. STORMS
• Storms are taking
place in seasons
where there didn’t
use to. In many
places, it doesn’t
rain in autumn or
spring time but, on
the contrary, it does
in summer and
winter.

4. STORMS
• 1. What is
happening with
storms?
• 2. When does it
rain? Which
seasons?

5. DROUGHTS
• It is a fact that many
areas are in a state of
desertification.
• The lack of water is
affecting not only
woods and forests but
it is the origen of the
spread of many
diseases in
underdeveloped
countries.

6. DROUGHTS
• 1. What do you
understand by
desertification?
• 2. What is the lack
(manca) of water
causing in
underdeveloped
countries?

7. HURRICANES
• If the weather becomes
warmer, more water
evaporates from seas
and lakes,
consequently, we may
have more clouds and
heavy rains that in
some places become
hurricanes.

8. HURRICANES
• 1. Why does water
from seas and
lakes evaporate?
• 2. A hurricane can
be the result of
clouds and
............... rains.

9. FLOODS
• A flood is produced
when there is an
overflowing of water
onto land that is
normally dry.
• This happens with the
overflowing of rivers or
with very long-lasting,
heavy rains on flat
surfaces of land.

10. FLOODS
• 1. What happens
when the surface of
the land is very dry
and there is too much
water coming?
• 2. Which two
phenomena can
cause a flood?

11. GREENHOUSE EFFECT
• Burning fuels like wood,
coal or petrol produces
carbon dioxide (CO2) and
other gases.
• The mixture of such gases in
the atmosphere becomes
too concentrated and the
heat produces the so-called
global warming. Man is
responsible for the
“enhanced greenhouse
effect”

12. GREENHOUSE EFFECT
• 1. What’s the
name of the main
gas emitted to the
atmosphere?
• 2. The heat that
the gases in the
atmosphere
produces is called
..................
..................

13. EARTHQUAKES
• Shaking and
vibration at the
surface of the earth
resulting from
underground
movement along a
fault plane or from
volcanic activity.

14. EARTHQUAKES
• 1. The earth can
shake and
vibrate in certain
areas, but
especially in fault
.............. or as a
consequence of
...................
activity.

15. DISEASES
• Farmers might not be
able to grow traditional
crops because there
may be too much rain
or not enough. Some
diseases may increase.
Some scientists say
that another 20% of the
world’s population
might live in areas
where you can get
malaria.

16. DISEASES
• 1. Give the name of
the disease that
might appear more
frequently in many
areas of the world.
• 2. What do you
understand by
“traditional crop”
Crop: collita

17. FOREST FIRES
• Each year, fires burn
millions of hectares of
forest worldwide
• The Mediterranean
forests are under
serious threat, with
forest fires, in most
cases deliberately set,
playing a major role in
their degradation and
bringing about huge
social, economic and
environmental effects.

18. FOREST FIRES
• 1. Mention an area
where forests are
seriously threatened?
• 2. Is Catalonia
suffering from forest
fires? If so, which is
the season where
most of the fires are
produced?

19. AIR POLLUTION
• Air pollution is
especially prominent
where high pressure
dominates.
• Regions susceptible to
air pollution problems
result from the
interaction of climatic
and topographic
conditions in the
presence of pollution
sources

20. AIR POLLUTION
• 1. The regions where
there can be more
pollution problems
are the areas with the
presence of
...............
....................
* 2. Can you mention
any example of
pollution?

21. GLOBAL WARMING
CONSEQUENCES
• Scientists say that the earth could warm by an additional 7.2
degrees Fahrenheit during the 21st century if we fail to reduce
emissions from burning fossil fuels, such as coal and oil.
• This rise in average temperature will have far-reaching effects.
• Sea levels will rise, flooding coastal areas.
• Heat waves will be more frequent and more intense.
• Droughts and wildfires will occur more often.
• Disease-carrying mosquitoes will expand their range.
• And species will be pushed to extinction.
• Unfortunately, many of these changes have already begun.
