Answer 1

Sorry I didn't see your question earlier otherwise I'd have given you an answer before now.

I wrote a report about global warming which covers all the points you mentioned. I adapted a version specifically for Yahoo Answers, I won't paste it here as it's very long but if you go to this question http://answers.yahoo.com/question/index;_ylt=AjD1smzKEtamw90mewybSmbsy6IX?qid=20070312182624AAmYqxF you can read it there.

It's also online here http://profend.com/answers/global_warming.html and is easier to read.

It will also be available as a website here http://profend.com/global-warming/index.html but it's not finished yet.

Just read the above answer by Molly. Things might be different in the future but it's not going to get so bad. Even if all the ice and snow on the planet melted there would still be plenty of land left. Going from memory I think it's a 120 metre rise in sea levels if everything melted. A lot of the ice is in extremely cold places and for that to melt the temperatures would have to rise by 70 degrees C. That would be so high that water in places near the equator would boil. The world will still be here as will the future generations, things may be very different but humans will survive.

Answer 2

Global warming is the gradual increase in global temperatures that has happened over millenia - and will continue to do so, though sometimes cooling, sometimes warming.

Global warming is caused by the sun and, indirectly, by sun spot activity. As a result of global warming, the oceans release more co2 - CO2 is an indicator - or "effect" it is not a cause. This is why global warming or cooling always PRECEEDS the co2 level changes. It does NOT follow it.

Even if co2 was a cause, the oceans generate > 99% of the co2 in the atmosphere. So in reality, humans can effectively do nothing with Co2.

The myth runs on because governments around the world pour BILLIONS into research, and hundreds of thousands of jobs are at stake - ditto with many of the green charities and causes. The truth is the money is being wasted in researching solutions to problems which we caused by sunspot activity - not by the <1% of co2 that humans generate.

Prevent global warming? Find a way to control sunspot activity.

For a very interesting documentary on this - with some pretty powerful facts, watch this http://video.google.com/videoplay?docid=-4520665474899458831&q=great+global+warming+swindle

Of course if you wish to bang on about co2 like the rest of the sheep, feel free to just give me a thumbs down and go turn a few bulbs off :)

Global warming is when the weather gets hotter. Pretty soon, if global warming keeps occuring, all the ice caps will melt away and the U.S.A will be wiped out by water. No more life will be on earth and the Earth will just be a circle of water orbiting the sun.

GW is is when heat is held close to earth by gasses that have never been there before plus other gasses like pollution. If you study CFC's you will learn that we caused the ozone layer to have a big problem. Methane is another big problem gas. Can we clean them up-YES. That is why I sent this letter to Al Gore:

Putting the technology together to start cleaning up and reintroducing new ozone to the atmosphere is possible. The cost and size of this project means taking a long term commitment. I am proposing the biggest cleanup in history. Al, I do not see any proposal that is realistic or proven at any cost, not even Washington can solve this problem. But if every person on earth does his or her share, we may be ok. Never-the-less, I see governments acting like a deer in a car’s headlights and people doing the same thing. The inevitable is almost upon us. Cleanup and change is the only option.
The first cleanup machine starts with a ten billion dollars investment. Ten year later with twenty-five machines operating, these machines will produce enough ozone to replace both holes at the poles. But more importantly, these machines will remove chemicals that deplete the ozone. Beyond making ozone, decreasing the poisons that deplete ozone, these machines reduce the major greenhouse gases and unbelievably we can have all this for fewer than one hundred billion dollars.
Beyond cleaning up our atmospheric mess as I am suggesting, we humans must do a better job reducing or cleaning up carbon monoxide, collecting and storing methane and ethane for fuel, burning less of everything, cleaning up our forests and using more solar insolation. Solar steam electric generators are the type of systems we need and are 90 percent efficient and near 100 percent if heat recovery is used. I believe nearly 30,000 MW are needed in the USA and Mexico over the next 30 years. This opens the door to new electric cars, new construction vital to our way of life, new bullet trains, and these industries produce new high paying jobs. From small scale solar generators on malls, to 2000 acre collector sights, these systems are viable and ready for production. The Federal Government must give up some land, money and have less regulation to help save the planet from disaster.
Al, spreading the message that we can help ourselves is a key to the development of these businesses. Washington can help: the businesses need grants, patents, land and regulations. Congress must create a pollution surcharge. From gas, coal, diesel, wood to cooling towers, from cattle, other ranches to cigarettes, from agriculture burning to airplane passengers, this surcharge can fund parts of these projects and many stationary pollution control devices in general.
Your personal support is very important to getting the atmosphere cleanup started and developing sights for solar generators.

Answer 5

in case you desire to obtain grant money for climate analyze, do you think of which you will get a cheque in case you're saying," i desire the availability, as i think of that i will coach 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 link between the quantity of Co2 interior the ambience, and an boost in international temperatures. The WWWF pictures of the polar bears swimming have been taken interior the Arctic summer time; while the ice cap partly melts, as they could no longer arise to image interior the wintry climate. The ice grew to become into too thick! The East-Anglian uni analyze figures. "Oh! The figures do no longer tournament our expectancies. Oh properly. shop quiet. because of the fact all of us understand that we are stunning." while the perception, and the religion is extra significant than squarely dealing with the valid doubts of quite some non grant-supported scientists, technology has been superceded by making use of religious zealots. As Oliver Cromwell colourfully pronounced." I pray thee, interior the bowels of Christ, evaluate that thou mayest be incorrect."

Answer 6

1) gobal warming is like the weather get hotter and hotter..the big ice at north and south of the earth melting....then all the weather will become weird, such as when summer time it should be 30'c but it become 35'c...o rain heavy until float...

2)Many....like the chemical thing tat produce chemical air....fridge, air-con, smoke form car o factory...and many more..

3)Plant more tree..save more tree....dun owes open the fridge or switch on the air-con..

tat all for my answer...

Answer 8

i will answer part of 2 and 3
its a big subject

some home truths

politicians and scientists who work for politicians have downplayed the facts because solutions are expensive and means change and change effects many people income,and most of the world is kept in the dark of the real things that are going on.

: i have seen lands that have been turned from jungle into desserts by people in a matter of a couple of years ,because of the slash and burn method used by settlers and expanding agriculture,and i have seen rivers dry up because of deforrestation in many places in Africa and Mexico ,

i live now by the side of a river in Mexico where,in 30 years 5 species of fish have become exstinct .
and part of the year the river is dry this is for longer every year because of over use of water by agriculture and as a result of deforrestation.

there are natural cycles in the planets life
but a lot is influenced by mans existance ,and this is increasing with overpopulation,putting strains on Natural resources and increasing contaminations as well as destructions of essential componants the ensure living conditions for all life forms

in North Africa,India,Mexico ,millions of people are effected by land loss and desertification


in recent times thousands of people have died because of exessive heat,usually old people.in India ,Mexico and France,
deforestation causing desertification,the desert conditions causing very cold nights and scorching hot days

in china, thousands of what used to be farmers are running for their lives from the dust storms that have burried their towns and turned their lands into dessert,the globe where they were got to hot for them .
and instead of producing food they are now needing it from some where else,and they will drastically effect the world food prices when they start buying water in the form of grains ,at any cost destabalising governments, in some countries ,could be the result
(are you seeing more Chinese around interested in agricultural lands ,we do here in Mexico)

,the Sahara is growing by 7 kilometers a year
and all of the desserts we know are a results of mans actions ,and they are increasing ,not getting less ,in the dinosaurs days ,there were no desserts.

collectively this planet is drying up because of bad farming practices like,over grazing and fertilizers,

as far as the food production is concerned, Global warming or some of its effects are serious,rising seas result in landloss

each degree rise in temperature means 10%crop loss

more landloss because of desertification every year,we have less areble land to produce food ,for an extra 70 million people ,

and there is less and less water (because of deforestation),to irrigate this production ,
and there are less and less farmers to do it..
who are overpumping deep carbon aquifiers
who are plowing more and more unstable lands because they have lost so many million hectares to desertification ,
because of bad farming practises ,such as using fertilizers and heavy machinary or over grazing

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 ,are another matter.

Global warming is in theory reversable,but it will mean global co operation between all countries ,and taking into account human nature and the world politics ,it is unlikely that this will happen,

At least not untill we are all in the middle of planetary disastres and it becomes a battle for the survival of humanity every where.

SOLUTIONS
if you want to help the planet ,plant a tree every week ,if everyone on the planet did we we would be able to reverse the destructive processes

reduce carbon emisions,and they are already working on that by alternative forms of energy and regulations on carbon producing materials,aerosol cans,burning rubbish,industrial chimneys,powerplants etc.

the capture of carbon and the production of water and assist the aquiferous manta.

the world bank pays large subsidies for reforrestation to capture carbon and the best tree for this is the Pawlonia

Waterharvesting projects ,such as millions of small dams.to redirect over ground waterflows from the rains into the ground to supply subteranian water supplies.

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.

education to motivate people to auto sufficiency by building more home food gardens.

education on environmental awareness
education on family planning to curb over´populaion

Agricultural education and improvements to follow the principals or sustainability and soil management.

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

recicling wastes,limit water use
