Slide 3
What is the global warming? Global warming is increasing the
average temperature of the atmosphere and oceans on Earth, which
occurred from the 1950s. Often as a synonym for global warming
using climate change. Evidence for warming of the climate system
includes observed increases in global average air temperatures and
ocean waters, widespread melting of snow and ice and rising global
average sea level.
Slide 4
Initial causes of the global warming 1. Greenhouse effect 2.
Solar activity 3. Volcanic activity
Slide 5
There is a close connection between greenhouse gases and global
warming
Slide 6
What the greenhouse gases are? o Carbon dioxide (CO 2 ) o Water
vapor (H 2 O) o Nitrous oxide (N 2 O), (NOx) o Methane (CH 4 ) o
Chlorofluorocarbons o Sulphur hexafluoride (SF 6 ) o Nitrogen
trifluoride (NF 3 ) o Hydro fluorocarbons (HFCs)
Slide 7
Carbon dioxide (CO 2 ) o Electric Power Station(EPS) o Burning
Oil o Burning Coal o Burning of waste
Slide 8
Water vapor (H 2 O)
Slide 9
Nitrous oxide (N 2 O), or (NOx) o Thermal Power Station o
Transport o Chemical Industry o Combustion
Slide 10
Methane (CH 4 ) o Decomposition of organic waste o Decay of
organic waste o Marshes o Dumping-Ground
Slide 11
Chlorofluorocarbons o CFCs o Aerosol preparations
Slide 12
Properties of greenhouse gases o They have the ability to
absorb and retain heat in the atmosphere o They have different
absorption capacity
Slide 13
Consequences of the greenhouse effect o The sea level has risen
of 10 to 25 centimeters during the last 100 years, mainly due to
the expansion of water when heated. o Melting glaciers. o
Permafrost in Alaska and Siberia have begun to melt, damaging
ecosystems and infrastructure. o Heating and melting the tundra
will lead to melting of organic matter and the release of captured
carbon and methane.
Slide 14
Solar activity Solar activity means changes in the amount of
solar radiation in form of energy. Scheme of solar energy over the
years.
Slide 15
Volcanic activity This is a very fast process when a large
volcano erupts for a few days in the atmosphere emit more gas than
it can create all human activity for several months.
Slide 16
Underwater volcanoes o Underwater volcanoes warm water of the
oceans. o Increased activity may lead to fertilization of ice with
catastrophic consequences. o Volcanic eruption was accompanied with
earthquakes, geysers and hot springs.
Slide 17
Reasons for the global warming The industrial revolution and
the industrial society
Slide 18
A growing need for energy
Slide 19
The transport
Slide 20
Domestic heating
Slide 21
Consequence of the global warming Raising the temperature with
20 C to industrial society today (after 1950).
Slide 22
Forecast: By the end of the 21st century temperature will
increase with 1.5C - 5C.
Slide 23
Average global warming of 2C means: It threatens millions of
people at risk of hunger, malaria and flooding. Billions face an
increased risk of a shortage of 2. Consequences especially for the
poor and developing countries, especially in the region of the
Sahara Desert, southern Asia, parts of Southeast Asia and Latin
America. It threatens harmful consequences main ecosystems of the
Arctic and Antarctic to the tropics.
Slide 24
The loss of forests, wildlife will affect all life on Earth.
Risks of melting of ice sheets and the possibility of raising the
level of the World Ocean with meters in the next century,
especially in Greenland and Antarctica (5-7 meters). The increase
in sea level threatens human life everywhere, especially in areas
with low altitude.
Slide 25
NATURE IS ABUNDANT AND WELL BALANCED!
Slide 26
Our planet is in danger!
Slide 27
Reality that surrounds us today: Natural disasters (droughts,
floods, heat waves, storms) Increasing the level of marine
Migration of flora and fauna Gradual disappearance of glaciers Low
yields of crops
Slide 28
Slide 29
Scheme of climate change over the years
Slide 30
Consequences of global warming and the greenhouse effect
Slide 31
The number of hurricanes has almost doubled for the last 30
years Melting of glaciers has increased more than twice for the
last decade At least 279 species of plants and animals are already
responding to the global warming Mortality would double in the next
25 years (up to 300,000 people per year)
Slide 32
Heat waves will be more intense and drought and forest fires -
more often Global sea levels could rise with more than 1 meter
strips melting of glaciers. This will destroy the coastal area
around the world. By 2050 the ice of the Arctic Ocean can be
fused.
Slide 33
How to keep the climate: Limiting greenhouse gas emissions(2,
4, 2, CFCs) by humanity Reduced energy consumption Development and
purchase of technologies with low CO2 Adapted measures (replacement
of energy sources, increased use of alternative sources-wind, water
and sunlight) Preservation of natural resources
Slide 34
What can each of us take to reduce global production of 2 ?
What can each of us take to reduce global production of 2 ?
Slide 35
Steps by which "fix" global warming step 1 Be informed about
the environment. Express your opinion and concerns. step 2 Take a
quick shower instead of a bath. Wash your clothes in cold or
lukewarm water. step 3 Buy energy-saving fluorescent light bulbs
for the places you use most often. Turn off lights whenever
possible.
Slide 36
step 4 Insulate walls and ceilings in your home in this way you
can save about 25% of your heating bill. step 5 If you need to
change your windows, select a model that would save the most
energy. step 6 When you replace appliances in your home, choose an
energy efficient model. step 7 Turn off your water heater
thermostat when water is hot enough for 5O degrees.
Slide 37
Climate change is too big problem, but each of us can
contribute by changing everyday habits Here's what we do: We are
trying to change attitudes towards nature and enhance ecological
culture of the people around us. Planting even a tree near our
house. We separate paper, plastic and glass for recycling. At home
regular cleaning of air conditionings filters. The cleaned filter
saves 15% of energy used.
Slide 38
Here's what we do: Unplug the charger when the battery is
charged. Reduced 1 degree temperature of the rooms in which we live
and learn. Use less aerosol sprays. Whenever possible the family go
walking instead of using the family car.
Slide 39
SAVE THE PLANET!
Slide 40
Conclusion During the international meeting in Kyoto (Japan),
dedicated to the global climate change in XXI century, delegates
from 160 countries adopted the Convention requiring developed
countries to reduce the discharge of carbon dioxide. The Kiotski
Report require 38 industrialized countries to reduce the disposal
of waste products containing 5% CO2 in the period of 2008- 2010
comparing in 1990. EU committed to cut CO2 disposal and more; heat
emissions by 8%, in U.S. 7%, in Japan 6%. It is considering the
volume of gas to be reduced.
