The greenhouse effect is a process where thermal radiation from the Earth's surface is absorbed and re-radiated by atmospheric greenhouse gases, leading to higher temperatures. Human activities, such as burning fossil fuels and industrial processes, are enhancing this effect, resulting in issues like climate change and rising sea levels. Organizations are implementing green management practices to mitigate the greenhouse effect and promote a greener future.

2. Since part of this re-radiation is back towards
the surface, energy is transferred to the
surface and the lower atmosphere.
As a result, the temperature there is higher
than it would be if direct heating by solar
radiation were the only warming mechanism.
The greenhouse effect is a process by which
thermal radiation from a planetary surface is
absorbed by atmospheric greenhouse gases, and
is re-radiated in all directions.

4. The greenhouse effect is a warming near
the Earth's surface that results when the
Earth's atmosphere traps the sun's heat.
The atmosphere acts much like the glass
walls and roof of a greenhouse.

5. The greenhouse effect was
discovered by Joseph Fourier in
1824.
First reliably experimented on by
John Tyndall in 1858.
First reported quantitatively by
Svante Arrhenius in 1896.

7. • Human activities are enhancing the Greenhouse Effect,
because we are continually adding heat-trapping greenhouse
gases to the atmosphere by factory emissions, vehicle
emissions, etc. Such gases include carbon dioxide, carbon
monoxide, chlorofluorocarbons, methane and ozone. The
table on the next slide shows some examples of natural and
man-made sources of some ‘Greenhouse Gases’.

9. 1. Faster Ocean warming and catastrophic sea level rising
2. Polar ice caps melting
3. Climate change due to Green House effect.
4. Health Problem

10. • Many reputed organization now taking several steps for reducing greenhouse gas
effect. They are doing green management process for reducing greenhouse gas
effect. Among them some of those company’s name given below-
HSBC BANK
BRITISH AND AMERICAN
TOBACCO
UNILEVER
GRAMEENPHONE
“HSBC BANK”
Obtain “the daily
star” green
management
award 2011.

11. 1. Use Green technology
2. reuse and recycle
3. Take steps at Home and Office
4. Learn Smarter car usage
5. Increase Social Awareness
6. Support ‘Emissions trading’
7. Support ‘Kyoto protocol’

12. • Water level rises of Bay of
Bengal
• Abrupt climate change
• Different skin diseases
• Causes natural calamities
• Impediment of agricultural
production etc.

13. Prevention is better than cure.
We should work towards a greener future.
