2. GLOBAL WARMING:
• Global warming is the
unusually rapid increase
in Earth's average surface
temperature over the
past century primarily
due to the greenhouse
gases released by people
burning fossil fuels.

3. GLOBAL WARMING IS CAUSED BY

4. WHO
FOUNDED
GREEN HOUSE
EFFECT
Svante Arrhenius

5. Svante Arrhenius (1859-1927) . A Swedish scientist who
was first to claim in 1896 that fossil fuel combustion may
eventually result in enhanced global warming. He proposed a
relation between atmospheric carbon dioxide concentrations and
temperature.

8. Greenhouse gases
•Greenhouse gases are the gases present in the atmosphere
which reduce the loss of heat into space and therefore contribute
to global temperatures
•Greenhouse gases are essential to maintaining the temperature of the
earth
•The term greenhouse gas is applied to, in order of
relative abundance: water vapour, carbon dioxide, methane, nitrous
oxide, ozone and CFCs. •
•

9. Global warming stresses ecosystems through temperature rises,
water shortages, increased fire threats, drought, weed and pest
invasions, intense storm damage and salt invasion

10. • The first way to prevent climate change is to move away from
fossil fuels. What are the alternatives? Renewable energies like
solar, wind, biomass and geothermal.
SOLUTION FOR GLOBAL WARMING
• Producing clean energy is essential, but reducing our
consumption of energy and water by using more efficient
devices (e.g. LED light bulbs, innovative shower systems) is
less costly and equally important.
• Promoting public transportation, carpooling, but also electric
and hydrogen mobility, can definitely help reduce
CO2 emissions and thus fight global warming.
• In order to reduce the CO2 emissions from buildings - caused
by heating, air conditioning, hot water or lighting - it is necessary
both to build new low energy buildings, and to renovate the
existing constructions.
• Encouraging better use of natural resources, stopping massive
deforestation as well as making agriculture greener and more
efficient should also be a priority.
• Adopting responsible consumption habits is crucial, be it regarding
food (particularly meat), clothing, cosmetics or cleaning products. Last
but not least, recycling is an absolute necessity for dealing with waste.

11. WHAT IS KYOTO
PROTOCOL

12. KYOTO PROTOCOL
• The Kyoto Protocol is an international treaty which extends the 1992 United Nations Framework Convention on
Climate Change (UNFCCC) that commits state parties to reduce greenhouse gas emissions, based on
the scientific consensus that (part one) global warming is occurring and (part two) it is extremely likely that
human-made CO2 emissions have predominantly caused it.
• The Kyoto Protocol was adopted in Kyoto, Japan, on 11 December 1997 and entered into force on 16 February
2005. There are currently 192 parties (Canada withdrew from the protocol, effective December 2012) to the
Protocol.
• The agreement aimed to reduce carbon dioxide (CO2) emissions and the presence of greenhouse gases
(GHG) in the atmosphere.
• The essential tenet of the Kyoto Protocol was that industrialized nations needed to lessen the amount of
their CO2 emissions.
