Strategia di Lisbona

Costruire l’Europa
dell’ istruzione e
della formazione
Quando fai piani per un anno, semina grano.
Se fai piani per un decennio, pianta alberi.
Se fai piani per la vita forma e educa le
persone. Proverbio cinese: Guanzi (c645BC)

Climate changes
Anthropic responsibility
A European Challenge
Former temperatures within
major periods of glaciation.
Extent of ice from Medieval period to
20th century.
From the 1850, in
coincidence with the
Industrial Revolution,
medium temperature
of the Earth has
increased because of
the pollution.
Increasing of temperature from 19th
century to 2000.
1970: Scientists denounce first
alarms on the ozone layer.
The map shows the increasing of the hole
of ozone.
1985: English scientists discover a hole in the ozone
layer over Antarctic.
1989: Canadian scientists find another hole over the
Artide.
CO2 emissions from industrial processes
This map depicts the unequal distribution
of industry in the world.
Precipitation patterns are changing
on global scales…
The world oceans are heating up.
The oceans have
absorbed about 30
times more heat
than the
atmosphere since
1955

Visible effects:
• Changing in
farming
• Increasing of
drought
• Changing of ecosystems.
• More common and more
severe weather events
• Warming of sea-surface
temperatures.
• Melting of artic sea ice.
• Rising of sea level.
• Flooding due to
heavier rainfall

Dangerous greenhouse gases
Oceans are a huge thermic
mass that gets easily warm but
with difficulty colds off.
Carbon dioxide melts in the
oceans which become acid,
causing problems to organisms.
CO2+H2O
H2CO3
H+ + HCO3-
If the oceans heat up, there
will be a rise in the atmosphere
of carbon dioxide and of
methane, two of the most
dangerous greenhouse gases.
Endangered species
Endangered species threatened by climatic
change.
What will change ?
Global temperature is expected to increase by
between 1.4 and 5.8°C (2.5 to 10°F).
The Northern Hemisphere cover should decrease
further, but the Antarctic ice should increase.
The sea level should rise by between 9 and 88 cm
(3.5" to 35").
Positive consequence
Some crops and forest products could
benefit from a small climate change.
Negative consequences
Melting of polar ice caps
At the North Pole the ice will shrink by 10%
The thickness above the water will decrease by
about 40%.
The ice sheet above the Antarctic continent will
become unstable.
Glaciers are retreating
75% of the glaciers in the Swiss Alps will disappear
by 2050.
Extreme weather
•Effects on Gulf stream
•The Gulf stream could
get slower.
•There will be a rise of
heat at the Equator.
•There will be more
frequent hurricanes and
rainfalls.
The issue of Monsoons
•The Indian Ocean could get warmer.
•The monsoons will stop blowing.
•Nations “sustained” by the monsoons will be seriously
damaged.
The “War Effect”
First U.N. Security
Council debate on
climate change:
droughts, floods and
rising seas linked to
global warming could
spur conflicts in
coming decades.

The Institutions and the Climate
Changes
EU:
United Nations Framework Convention on Climate
Change (1992)
Kyoto Protocol (1997)
European Climate Change Programme (2000)
EU Emissions Trading Scheme (2005)
European Commission Communication "Limiting
Global Climate Change to 2 degrees Celsius: The
way ahead for 2020 and beyond” (January 2007)
Calendar of Events 2007
Climate
change:
an issue
that
affects
everyone.
What can we do about it?
Don’t overheat your home. Reducing the
temperature by just 1°C can cut up to 7% off
your family’s energy bill. 70% of the energy
used by households is for heating.
Don’t forget to switch off the lights when you
don’t need them.
Recycle
Avoid taking the car. Walk or cycle instead!
Plant trees. Five trees soak up around one
tonne of CO2 throughout their life time.
Don’t waste water.
