HI BUDDIES, TODAY WE SHALL DISCUSS GLOBAL WARMING, ITS CAUSES, EFFECTS AND REMEDIES.DEAR FRIENDS, BEFORE WE START OUR TOPIC WE SHOUD MAKE AN OUTLINE. FOR PRACTISE REASON I WILL MAKE IT FOR U ROUGHLY BEFORE displaying ITS ORGANISED COPY. So what u have to do, is simply putting the bullets in order.


OUT LINE:
---GLOBAL WARMING IS RISE IN AVERAGE TEMPERature of earth's atmospher,surface and occeans.
---For the last century there is a rise of 0.6 c in the global mean temprature .
---its causes are the following anthropogenic gases: co2 ,N2o(nitrous oxide),chlouro flouro carbons(CFCs),methane,etc
---Deforestation
---burning of feul in vehicles and factories.
---rise in sea level and chances of submerging of low lying areas ,such as coastal areas.For instance 16-17% of Bangladesh would submerg.
---extinction of some plant and animal species.
---in some parts of the world there would be more rain and some of the parts of the world will experience drought like conditions.(desication of earth)
---In someparts there would be boost in agriculture initialy and some parts it would be ruined.
---migration and displacement of people.
---food crises.
---there would be surge in deseases,people would die earlier,more cancer of skin.
---these anthropogenic gases,also called as green house gases,absorb ultra violet beta rays and causes green house effect,so slows the natural out flow of heat from the earth's surface to the space.
---coral reafs are in danger,these reafs are the algeas that are the major food for many marine animals,they also absorb co2 and convert it in to o2 .
---ice caps and glaciers are melting.
---aternate resourses of energy should be used.
---planting of more trees (plantation).
--- cutting of trees should be stoped.
---25%of the co2 of the world is emitted by the US alone.
---50% of the co2 is released by 80%of the world (that is developing countries)
---water vapours is aso a green house gas
---kyoto protocol
---Bali conference
