Climate Change Managing the Global Greenhouse

1. Presented by

2. Introduction
Climate Change is a change in global or regional
climate patterns, in particular a change apparent
from the mid to late 20th century onwards and
attributed largely to the increased levels of
atmospheric carbon dioxide produced by the use
of fossil fuels. Greenhouse effect, a warming of
Earth's surface and troposphere (the lowest layer
of the atmosphere) caused by the presence of
water vapor, carbon dioxide, methane, and
certain other gases in the air.

3. Introduction
Most scientists agree that gases like Carbon-dioxide
(coal, oil, and gas), Methane (rice farming and cattle
raising) and Chlorofluorocarbons (used in
refrigeration, air-conditioning, aerosols and other
applications) produce a greenhouse effect in the
earth's atmosphere and increase the earth's
temperature. Western industrialization (the
consumption of coal, oil, and gas) and rice farming
and cattle raising release the huge tons of greenhouse
gases.

4. Global Warming: Facts and Uncertainties
Global warming is a gradual increase in the overall
temperature of the earth's atmosphere generally
attributed to the greenhouse effect caused by
increased levels of carbon dioxide (CO2), methane
(CH4), CFCs and other pollutants. It is agreed that an
increase in the greenhouse gases will have a warming
effect on the earth's climate. Similarly, the potential
effects of greenhouse gases will be both long-term and
global.

5. Global Warming: Facts and Uncertainties
Moreover, the greenhouse gases in the atmosphere has
been increasing because of the growth of industry
depended on the burning of coal, oil and gas to
produce energy and the problem of feeding the
world's rapidly growing population depended on
deforestation and agriculture within the last century.
The lack of consistency in global warming suggests to
some scientists that the effects of the greenhouse on
global climate have been overstated.

6. Potential Effects of Climate Change
• There will be extremely serious consequences
for natural ecosystems, agriculture, and human
settlements.
• The forest belt would be under immense strain
and would probably not able to adapt and
results in the destruction of the other
ecosystems worldwide.

7. Potential Effects of Climate Change
• Agriculture will also be seriously damaged by
unchecked global warming.
• Higher temperatures are likely to be accompanied
in some regions by a significant reduction in rainfall
and results in reduction of agriculture production.
• Human settlements in coastal areas especially in the
higher latitudes will face threat of flood because of
the rise in sea level that force millions of people to
abandon their and create economic and social
problems.

8. Responding to the Threat
The industrial countries must take the lead to
reduce greenhouse productions because they are in
better positions in term of economic resources,
scientific knowledge, technological expertise and
responsibility.
A short-term strategy must be energy conservation
– a reduction in the use of energy produced by fossil
fuel burning by providing incentives to both the
manufacturers and consumers.

9. Responding to the Threat
A long-term strategy must be to replace fossils fuel
with environmentally safe, alternative sources of
energy by providing incentives for research into
alternative energy sources such as wind power,
hydrogen etc.
 Energy conservation policy is challenging because
the direct costs of conservation measures and
sustainable methods of generating alternative
energy will be enormously expensive.

10. Responding to the Threat
The developing countries are beginning to produce
greenhouse gas emissions equaling those in the
wealthier nations due to the pressure to feed, house, and
employ its growing populations by pursuing economic
development regardless of the cost to the environment.
To address the problems of poor countries, rich
countries should provide economic and technical
support and debt forgiveness with conditions to resolve
the problem of global warming .

11. Rethinking Our Priorities
• A global revolution in public and political thinking
will be necessary to raise huge amount of money
which is essential for addressing the problem of
global climate change effectively.
• Different Conventions and Summit agreement must
be followed.
• The growing capacity of science to provide reliable
information on climate change is sign of optimism.
