this is another point of view that does not seem to get enough attention,the effects of man through agriculture
WHO OR WHAT IS TO BLAME
Irresponsible Agriculture , expanding populations and its effects are the planets biggest enemies.
This text only covers some aspects of Climate change ,i.e.effects of deforestation and subsequent man made desertification ,because of irresponsible farming using chemicals ,over pumping carbon aquifers,over grazing ,wild fires (because of slash and burn gone out of control).
Water and air polution ,such as caused by
industrial contamination ,the contaminating effects of the cities(the internal combustion engine) ,are other stories.
All of these are also man made ,such as the high industrial chimneys pumping contamination into the clouds and the burning of tires,some of this polution has been found in the ice in the polar regions.
There are natural cycles in the planets life
but a lot is influenced by mans existance ,this is increasing with overpopulation,putting strains on Natural resources and increasing contaminations .
The thinner ozone layer helps to speed this up. This is caused mainly by air polution ,also as a result of mans actions.
In North Africa,India,Mexico ,millions of people are effected by land loss , desertification and some have died as a result.
Now many animals are becoming sick because of changes in temperature .
Vital links in the food chains are disapearing affecting other species further along in the chain .
We are witness to a mass exstinction ,for the first time since the dinosaurs.
Of the earth's estimated 10 million species, 300,000 have vanished in the past 50 years.
Each year, 3,000 to 30,000 species become extinct.
Everything is happening so fast it is not possible to monitor things any more.
The Sahara is growing by 7 kilometers a year.
Most of the desserts are as a results of mans actions.And they are increasing .In the dinosaurs days ,there were few desserts.
Collectively this planet is drying up .
Each degree rise in temperature means 10%crop loss
There is less and less water (because of deforestation),to irrigate Agriculture.
Arable lands and their farms are lost all over the globe. Many farmers sons abandon farming and head for the cities.
Northern China is drying up, what once were millions of food producing people, are now hungry refugees ,running for their lives from the all consuming dust storms.
This will have a great effect on world food prices when they start buying at what ever cost, to feed their people.
The farmers that are left have to feed some 70 million more people than the year before but with less topsoil(because of desertification and irreverible erosion)
Over the last half century,
Population growth & rising incomes have tripled world grain demand from 640 million tons to 1,855 million
In the near future the global farming community will not be able to feed every body ,food prices will continue to rise. .
RISING SEAS
The northpole is melting ,and we will know it without ice in our life times.
This does not affect the sea level ,because it is ice that is already in the water.but the melting ice from Green land and the south pole ,and the Glaziers is potable water lost forever and rises the sea levels.
Are We responsible ?
Is it the Sun?
Is it God who wants to punish us?
Is it Gaia who wants to clean some parasitic infestation?
Is it a Natural cycle?
Who cares ? that is not important any more
WHAT IS important -is that we are gonna be in trouble
WHAT CAN WE DO????????????????
The best we can do as individuals is be more responsible ,in our own neck of the woods
Organise well publicized clean up parties ,talk on the radio,hold citizan meetings, get the shools involved to plant trees and listen to environmental awareness talks.
If you do any cleaning up ,leave signs behind saying who cleaned,why and ask people not to start dumping rubbish again ,leave a hole or bins ,in case people come back with trash ,and they always do.
We have done a lot of comunity cleaning and if you dont leave alternatives or try to work on peoples guilt feelings (some people actually have those ,but not many) ,than your efforts are a waste of time.
That is what we do in Mexico.
POSITIVE ACTIONS
Print Tshirts with slogans ,hang posters all over the place (with recycled paper if possible).
Classify trash, take out all the organic waste and make compost with it ,the worst you can do is throw it with the trash,or burn it .
70% of contamination is due to organic waste that is mixed in with the garbage .
and it is just as bad in the sewer where it helps to breed rats and in the landfill it poisons the ground .
This is the easiest to take care of .
First of all we have to clasify trash ,at least keep the organic to one side ,like in a plastic bin with a lid .
If you got a few meters of ground ,you only need 1 or 2 square meters in a shallow hole ,(in the shade) ,that you can wet now and again .
Where you dump everything that is organic .
Toilet paper,bones vegetable cuttings ,eggshells,
deadbodies ,excrement ,cardboard,leaves,
shredded paper,old clothes (if they are organic),
Cover regularly with leaves or a piece of plastic,
to keep humid and to hide any smell .
REGULARLY spray some water over it ,but do not saturate it or the worms will die or leave.
The worms will decompose the wastes, turning it into beautifull black soil for the garden of flower pots .
If you are in a apartment ,if you have a balcony get a big plastic bin drill some holes in the side and lid ,
and add a few buckets of sand now and again to put over the trash ,you should realy stir or move the stuff at times to airate it ,and ensure that the decomposition is even ,keep moist
this rubbish does not get big very fast and the thing works for a long time with out getting full
----------------------Some more Positive thoughts
Global warming cannot be stopped but being friendlier to our Environment cannot be bad and maybe we buy some time.
If you want to help the planet ,plant a tree every week ,if everyone on the planet did we we would be able to slowdown the destructive processes.
Reduce carbon emisions,and they are already working on that ,by alternative forms of energy We need more regulations on carbon production.
Dont use aerosol cans,
Dont burn trash
Limit water use
Recicling wastes.
AGRICULTURE must invest in
Waterharvesting projects ,(such as thousands of small dams).to redirect over ground waterflows from the rains into the ground to supply subteranian water supplies.
Assist the capture of carbon and the production of water by promoting Reforestation.
The world bank pays large subsidies for reforrestation to capture carbon and the best tree for this is the Pawlonia .
Agricultural education and improvements to follow the principals of sustainability and soil management
GOVERNMENT
The protection of existing forrests.
Stop building more highways,
Urban planning to include vegetation
Stop building cities encourage people to return to the land to conduct their business from there ,which now has become possible thanks to the internet.
More environmental or land ,design to prevent bush fires,such as--fire breaks .
More dams,regulations and control for public behaviour.
Alternative effeciant public transport to discourage the use of the internal conbustion engine.
SCHOOL SYSTEMS
Education to motivate people to auto sufficiency by building more home food gardens.
Education on environmental awareness.
Education on family planning ,to curb overpopulation.
Here are a 100 more ways

There are certainly some natural causes and if you're writing your paper from this perspective then the key things you need to take into account are the way the world moves - it kind of wobbles about, and the changes in heat energy received from the sun.
The 'wobbles' are hard to describe in words, you really need to see diagrams to illustrate the movements - do a search for "Milankovitch Cycles" and you'll get some good results.
Changes in the sun are referred to as "Solar Variation", you might want to search this as well.
CO2 and water vapour are different things. Water vapour is the same as normal water but it's in gaseous form, it's incorrect to say that 95% of CO2 is from water vapour.
The amount of CO2 in the atmosphere is a little less than the figure you stated, it's actually 0.038%.
What's important about CO2 and the other greenhouse gases is that whilst there may only be small amounts of them, they are different from the gases that make up almost all the atmosphere.
It's a little bit like taking a glass of water and adding a drop of arsenic or other poison. Although it's only there in tiny amounts it's still enough to kill you. The atmosphere's a bit like that, most of it does nothing and is harmless but it's the little bits that we're adding which are important.
The three main gases in the atmosphere are nitrogen 78.084%, oxygen 20.946% and argon 0.934%. Together this adds uo to 99.964% of the atmosphere - pretty much all of it. These three gases are all elements meaning they're made up of single atoms.
Carbon dioixide and the other greenhouse gases are molecules, they behave very differently to the elemental gases because they have the ability to trap heat.
Might I make a suggestion for your paper in that you write about global warming from both perspectives - natural and manmade. You'll find this much easier to do as there's a lot of information available about the human contribution to global warming but not so much information about the natural contribution. It will also add balance to your paper showing that you've considered the different perspectives.

in case you elect for to get carry of grant money for climate examine, do you think of which you will get a cheque in case you're saying," i desire the grant, as i think of that i will tutor that the figures that the present paradigm relies upon are incorrect" ? the super environmentalist, David Bellamy, has been silenced, and refused airtime. there remains no shown causative hyperlink between the quantity of Co2 contained in the ambience, and a upward thrust in international temperatures. The WWWF photos of the polar bears swimming have been taken contained in the Arctic summer time; whilst the ice cap partly melts, as they could no longer upward thrust as much as image contained in the iciness. The ice exchange into too thick! The East-Anglian uni examine figures. "Oh! The figures do no longer tournament our expectancies. Oh properly. save quiet. because of the fact all of us comprehend that we are appropriate." whilst the thought, and the religion is extra considerable than squarely dealing with the valid doubts of a superb style of non grant-supported scientists, technology has been superceded by employing non secular zealots. As Oliver Cromwell colourfully reported." I pray thee, contained in the bowels of Christ, evaluate that thou mayest be incorrect."
