Answer 1

there are enough disaster areas in the world to come up with an inteligent analises ,you only have to investigate

POLITICS
ecologists and scientists who work for politicians ,get paid by these politicians and they have downplayed the facts because solutions are expensive and means change and change effects many peoples incomes,and upsets profit margins,so most of the world is kept in the dark of the real things that are going on.

MANS EFFECTS ON THE ENVIRONMENT

(this is limited to effects of people in the country,industrial effects on the environment and the internal combustion engine as well as the over all effects of cities ,is another story)

DEFORESTATION

expanding populations and expanding farming ,that has to keep pace with the expanding populations are very strong forces that encroach upon the rainforest's
clearing them for farming and settlement areas .

In Mexico is a famous jungle that the Media has been trying to save for years
the Naturists ,and the government ,keep watch .laws are made for protection the wild and to forbid logging.
TV put out a series of documentaries
there are campaigns in the News papers
and all of this has not made the slightest difference

Rainforest's always are in third world countries and always in third world countries corruption and the need for money s highest

ON THE GROUND
go to the countries on the equator ,check what has happened in history
and listen to what is going on in the many disaster areas on this planet today,(and there are more each year )

: 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 ,

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 and some have died as a result

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 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,


each degree rise in temperature means 10%crop loss

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.

Answer 2

What does it matter? Hasn't all Science now been proved a tax raising, one world govt. fraud? You do realize that all Science is so intertwined, and interdependent, that if one area of Science is "fake" , or a "fraud" , it would be like having an engine with wooden pistons. What area of Science is being faked? Is it just the Atmospheric Scientists? Are the Climatologists in on the world wide US tax scam? How many Marine Biologists do you think are faking data to suck up grant money? How long has this fraud been going on? What did they do with the real data before the scam was started? Do they have a secret convention every year to indoctrinate the recently graduated Scientists? Do they have a secret handshake to identify fellow tax conspirators? Is the current money shortage being caused by the phony Scientists hoarding all their ill gotten gains under their mattresses? With all Science being denied because of those stolen e-mails, will common sense finally prevail? I mean, any fool can easily see that it's the Sun warming us as it orbits the Earth. Nobody actually needs an elitist Scientist to know that the Sun moves across the sky, as the Earth stands still.

Answer 3

in my own opinion, i believe people cannot try to cop out and say they have not contributed to global warming. Think about the amount of cars in your area and then try to imagine how many there are world-wide; all that pollution is adding to the environment. Carbon dioxide emissions from humans are a major cause. The amount of elecricity we use is immense and everyone is guilty of ignoring the effects it has on the world.
This is a debate that can be thrown back and forth; back and forth. The main thing is is that we accept we contribute to global warming and try and do something about it. Nature is also a cause, but with the high increase of our throw away society - we need to take responsibility for our lazy actions we hve become accustomed to.
I think it is such a huge topic and people shouldnt be arguing one way or the other, they should be asking themselves; why with all the 'advanced technology' did scientists not spot it earlier and try and help prevent it?

Answer 4

The Greenhouse Effect is a natural process of the Earth.
Global Warming is a man-made process which is drastically altering habitats nowadays, and there is a pattern: nowadays people use much more oil and burn many more things, releasing gases that are surely to trap light in here, heating things up far out of the reach of the Greenhouse Effect.
Well, if burning oil has to do with Global Warming... and humans are the only ones who burn oil on this planet... is Global Warming something produced by humans? I think so.

Answer 5

As in everything, there is no black and white. For instance, the earth used to be thought of as flat. Yes, in many areas, the Earth IS flat, but we know that in reality it is round. It took a LONG time for the big brains of the planet to accept that fact. As for global warming, there is no way that a planet that contains geoTHERMAL properties does not go through hot and cold cycles naturaly.....BUT...there is NO way that our parasitic lifestyle here on this planet is not taking a toll. It is kind of like sitting in the tub, and peeing. If you pee too many times, it is just WAY TOO FILTHY TO CALL A BATH! We are naive to think that our use of fossil fuels, the launching of rockets into orbit, the production of deadly materials for modern conveniences is not taking a toll at least a little. At the very least, our impact on the Earth is influencing the natural warming of the Earth.

Answer 6

More carbon dioxide comes from volcanoes, the sea,plants and animals than is man made. M.M accounts for only a very ,very small percentage of co2. The scaremongers and politicians will have us believe that we are causing all the problems but the only reason they are doing this is to tax us to the hilt.
If everyone had seen the prog on Channel 4 a couple of weeks ago they would realise that Global warming is a con. Just like Brown's budget and the whole of the Labour Party.

Answer 7

it is natural, If all the oil still remaining on the planet were burnt instantly the planet would have a natural way of dealing with it, the carbons both dioxide and monoxide would have an effect for a short lived time and the planet would settle down as tho' nothing had happened, what man adds to the planet in any way what-so-ever, is still evolution, it is the way of the universe and for the idiots who think they can control it, are living in cloud Cookoo land

Answer 8

There are a few scientists with some theory or other about why global warming is not caused by us.

The trouble is a vast body of data supports the fact that it is (mostly) us. The other theories don't have such a strong basis in data. Some (the sun, volcanoes) have always been seriously considered by climatologists, but are directly contradicted by the data.

The best summary of the data is here;

http://www.ipcc.ch/SPM2feb07.pdf

The data, not some brilliant theory, is why the vast majority of climatologists believe it is us causing it. Proof here:

http://www.sciencemag.org/cgi/content/full/306/5702/1686

And why this is true:

"the question of global warming was settled years ago for all but a few holdouts in the scientific community"

http://www.kansascity.com/mld/kansascity/news/nation/16620307.htm

If someone comes up with a theory with good data backing it up, it will be headline news. Right now, skeptical scientists are just a few guys with a theory and little or no data.

By the way, you need to fix the link.

Answer 9

Think ozone layer...holes don't just happen. The holes in the ozone layer has contirbuted to the global warming.

Oh and I don't think by global warming is only meant a rise in temperature. I think it refers to more extreme weather conditions than the natural rise in temperature. It's just referred to as "warming".

Of course beyond that there is the ethical element of stopping our greedy consuming attitude. Think 3rd World countries, think other species disappearing, think depleted resources that cause power games between nations. We shouldn't need global warming as a reason.

Answer 10

Global Warming is mostly natural. Very little of it (around 2% of it) is man-made from our factories and cars.

Answer 11

2% manmade and 98% natural.


What melted the ice when the last Ice Age ended thousands of years ago? SUV's?
