The document discusses the greenhouse effect and global warming. It explains that increased concentrations of carbon dioxide and other greenhouse gases in the atmosphere trap heat near the Earth's surface, causing the planet to warm. Carbon dioxide levels have risen from 275 parts per million 100 years ago to 375 parts per million in 2007 and are projected to reach 450 parts per million by 2040. The major sources of greenhouse gases are fossil fuel combustion, agriculture, deforestation, and industry. The effects of global warming include rising sea levels, worsening health impacts, and disruption of natural systems.
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.

Greenhouse a building made mainly of glass, with heat & humidity regulated for growing plants. The atmosphere acts like a glass in a greenhouse.
Atmosphere, like glass absorbs some of the long wave radiation emitted by earth and radiates the energy back to earth. In this way temperature of earth is maintained.
The atmosphere surrounding the earth in this manner plays a vital role in maintaining an even temperature on the earth’s surface.
A greenhouse is that body which allows the short wavelength incoming solar radiation to come in, but does not allow the long wave outgoing terrestrial infrared radiation to escape.
The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat to make the earth surface warmer leading to global warming.
We can work together to keep the environment clean so the plants, animals and people who depend on it remain healthy :) Working together, we can make pollution less of a problem and make our world a better place :D :)
This is a combined presentation done by me and my friends namely Nidhi Singh, Priyanka Pokharel,Swostina Ranjit and Rubina Khadka. Hope you will like this effort of ours.

Global Warming: Effect on Living Organisms, Causes and its SolutionsDr. Amarjeet Singh
In the present scenario many scientists, researchers
and environmentalists are expressing their deep concerns
about the overall changes. For continuous production of
Electricity Fossil and Fuels are being used. The burning of
these fuels produces gases like carbon dioxide, methane and
nitrous oxides which lead to global warming. The main cause
of global warming can be unsustainable human activities that
increase the accumulation of greenhouse gases. The hazard of
global warming is continuously causing major damage to the
Earth's environment. Most human beings are still unaware of
global warming and do not consider it to be a big problem in
the future. Living Organisms have to make efforts to
maintain health by recognizing and resolving abnormal
situations such as the presence of invading microorganisms.
Here we outline the effect on living organisms, causes and
how we can overcome it.
1. Green house effect
Meaning: Progressive warming up of the earth surface due
to high concentration of manmade carbon dioxide in the
atmosphere.
Concentration of CO₂ works like a glass panel of
greenhouse allowing short wave incoming solar radiation
to come in but preventing the long wave heat to re-radiated
out.
The natural outcome is warmer atmosphere -
100 years ago CO ₂ - 275ppm
In the year 2007 - 375ppm
In the year 2040 - 450ppm
3. The major green house gases
The gases with the properties of greenhouse are known as green
house gases.
Some gases in earth’s atmosphere for example, water (H2O),
carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O)
have a very special property .They do not absorb the visible light
from the sun, but they do absorb the infrared light radiated by
the Earth's surface. These are called "greenhouse gases" .
Carbon dioxide.
Halogen gases like Chlorofluorocarbons,
nitrogen oxide ,
methane etc.
5. Sources of greenhouse gases
1. Thermal power stations based on fossil fuels, mainly coal
and mineral oil emitting huge amount of CO₂.
2. Numerous factories and industrial chimney wastes
3. Automobiles
4. Deforestation and burning of fossil fuels.
7. Effects of Greenhouse effect
1. global warming and climate change.
2. Rise of sea level
3. Worsening health effects
4. Disruption of the water cycle
5. Changing forest and natural areas
6. Challenges to agriculture and the food supply
7. Effect on the ozone layer
8. Effect on oceanic climate
9. Country specific carbon emission

10. Control of Greenhouse Effect
Alternate sources of energy are to be used
Advanced and efficient technologies for reducing
emissions from fossil fuels.
Afforestation and reforestation on a large scale
Water logging should be avoided
Reduction of the use of CFC
Carbon market
11. Option for reducing Co₂

ocean

water
12. Global warming and Climate
change
The Sun's surface, which has an average
temperature of 10,000 degrees Fahrenheit (5810
degrees Kelvin), primarily radiates visible light.
The surface of the Earth has an average
temperature of 60 degrees Fahrenheit (288 degrees
Kelvin), so it radiates in the infrared part of the
spectrum.
The temperature of an object is determined by a
balance between incoming and outgoing energy.
13. For the Earth, the incoming energy is the absorbed light
from the Sun, and the outgoing energy is the infrared light
the Earth radiates out to space.
Due to the greenhouse effect the earth could not radiate
the total heat and thus make life possible.
Global warming is also happening because the blanket of
GHG are becoming thicker.
14. Consequences
As a result change of climate has occurred which threats
the sustainability of life. The consequences are as follows -:
Melting of polar ice caps and glaciers along with thermal
expansion of water.
More droughts and floods.
More terrible storms.
Many more hot days.
More diseases like malaria and dengue
Impacts of ecosystem would change the crop production
potential of a region specially Asia, Africa, South and
Central America.
15. Cont..
Forests may disappear and reduction of biodiversity.
Billions of people will be affected by problems of drinking
water supply, sanitation, and drought.
Projected rise of sea level is between 9 cm to 29 cm by
2029 and 96 cm by 2090. The South Asian region with ⅙
of the world population will suffer greatly.
Increase in heat stress mortality and diseases.
16. Who is responsible ?
Affluent and rich countries are responsible for
changes of climate.
Global energy consumption and CO₂ emissions
have increased 3 times between 1950 – 85.
In 1990 out of 21 billion tons of global emissions, 14
billion tons are emitted by rich countries.
US alone emitted 5 billion tons of carbon.
India emits 159 million tons.
