Is Global Warming Caused by Humans or is it a natural cycle?

Question

I am doing a research project on the debate over Global Warming. I will present both sides of the argument and determine where I stand. There are so many sides to this issue and its becoming difficult to sift through all of this information , I just want a clear cut and supported answer. If you can help me out by answering, or by referring me to a credible website it would be very helpful. Thanks.

Answer 1

The theory of man-made global warming is false, it is based on falsified or incomplete data. Lets take a look at what the global warming crowd claims, they say that the human output of CO2 is causing the greenhouse effect which is warming the planet. To see how outrageous this claim is try to guess how much of our atmosphere is made up of CO2, the correct answer is 0.03% of our atmosphere, almost nothing. How can such a small part of our atmosphere have such an effect on our entire planet, correct answer it can’t. Greenhouse gases exist naturally and have always been in our atmosphere. Greenhouse gases such as CH4 (methane), N2O (Nitrous Oxide), and water vapor are all put out into the atmosphere naturally in far greater concentrations than humans could ever match. Let’s take a look at water vapor, water vapor makes up between 1-4% of the atmosphere far more than CO2. Water vapor is given off into the atmosphere due to evaporation, so evaporation causes much more global warming than humans ever could. Other natural sources such as volcanic eruptions and the decomposition of plant and animal matter also put far more greenhouse gases than humans ever could.
So what is causing global warming? Well first of all the earth may not even be warming. http://wwwghcc.msfc.nasa.gov/temperature/ This is a collection of global temperatures collected by NASA that shows a general cooling trend especially around the polar ice caps. So assuming the earth is warming what could be causing it, the sun. Look at this graph also put out by NASA: http://science.nasa.gov/headlines/y2003/17jan_solcon.htm, it shows that the intensity of the sun is directly correlated to global temperatures and recent studies have shown that the sun is now warming than ever before, coincidence? I think not. Also consider that the other planets in our solar system, Mars in particular, are also warming: http://news.nationalgeographic.com/news/2007/02/070228-mars-warming.html
You have to keep in mind that the earth goes through natural cycles of warming and cooling, take for example the ice age and later warming of the earth enough to melt the ice.
Advocates of global warming will try and post evidence but the fact is most evidence for global warming comes in the form of general statements like “think of your children/grandchildren” that try to guilt you into agreeing with them. These ads are devoid of scientific proof and seek to toy with your conscience. Every once in a while you will see a graph submitted as evidence mostly from http://www.ipcc.ch/. Take a look for yourself, I search in vain for proof of global warming on this site, sure there are dozens of graphs showing the same data: CO2 rising along with global temperatures but where are the graphs for other greenhouse gases that make up a greater percentage of our atmosphere and are put out naturally, or graphs showing the percentage of greenhouse gases put out by humans verses the gases put out by natural sources. These graphs are not included because they disprove the theory of man made global warming. The IPCC has had a questionable past, it has published a deliberately falsified graph, the so called hockey stick graph, which left out a period of warming during the 1400’s. This warming period in the 1400’s was more dramatic than what we are seeing today, and it took place long before humans industrialized. This falsification was proven and a reprint of the graph appeared in the journal Nature. You may have seen claims that there is a scientific consensus on global warming like this one: http://www.sciencemag.org/cgi/content/full/306/5702/1686, this is an absolute lie, do you need proof? Here http://www.oism.org/pproject/s33p36.htm the signatures of over 17,000 scientists who disagree with the theory of man made global warming (check out the report on this site it does an excellent job of disproving global warming). You may have also seen reports about ice cores supposedly proving global warming, this is not true. Here is the truth about ice cores http://www.john-daly.com/zjiceco2.htm.
You may have the question why anyone would support this obviously false theory, the answer is money. Average people with no scientific background are being converted to the global warming crowd by the dozens due to the repression of evidence against global warming. This mass of people is the reason why notable people are jumping on the global warming bandwagon. Politicians are supporting global warming for votes, scientists are joining for media time and grants, and CEO’s are pledging their allegiance to gain customers who want to shop where the environment is being supported.
You may also wonder why I care, you may think we can only help the environment if we agree with global warming what’s wrong with that? I want to distinguish between global warming and helping the environment. I have no problem with environmentalist causes, in fact I support them, but global warming is taking this idea to the extreme. If you were to follow the guidelines set forth by people like Al Gore your lifestyle would be, these people want to tell you what light bulbs to use. The main reason however is money, why waste millions on studying global warming when we could be rebuilding third world countries and helping the poor. Global warming is a fear tactic used to get your money and your vote by unscrupulous members of society. Hopefully this will just fade away like the global cooling scare which was brought upon us in the 1970’s by the same sort of people using the same tactics. A last link http://www.worldclimatereport.com/ possibly the best resource for answering many of the questions raised by global warming. I urge anyone who believes in man-made global warming to look into some of the resources I have presented.

Answer 2

Rather than tell you that global warming is natural, manmade or both I'll refer you to a website I created specifically to answer this point. It's here http://profend.com/global-warming/

The site looks at argument for and against global warming - this should help you in your project, it also looks at the evidence and dispels the myths and errors. It's written in plain English and every fact and statement is cited back to it's original source. Check out the Links page as there's lots more info available there.

Answer 3

Humans are part of nature, and also the cause of global warming, so it must be a natural cycle too. Just look at the graph of co2 in the atmosphere vs. the level of industrial activities side by side and I think you have your answer.

Answer 4

The increase and decrease of carbon in our atmosphere, is part of the earth's natural cycle. Carbon is absorbed into trees and plants and algae to create photosynthesis during the spring and summer months, which takes carbon out of our air, and in the winter and fall months, leaves fall, and dead and decaying matter decomposes and carbon is released back into the air. However, we are releasing EXCESS carbon. Yes carbon, is always in our atmosphere, and its important so plants can photosynthesis and survive, but we have thrown the healthy balance of carbon in out atmosphere off, when we burn fossil fuels and use energy. More carbon is being released than nature knows what to do with. This extra carbon has thickened out atmosphere, which makes it more difficult for sunlight to escape our atmosphere. Meaning that all of the heat, and energy from the sun is staying in our atmoshphere, making our climate alarmingly warm. So yes, carbon is always in our atmosphere, but humans have put more carbon in the atmosphere, which causes global warming

Answer 5

There's a completely overwhelming amount of scientific data showing that it's real and caused mostly by man.

Short version:

http://en.wikipedia.org/wiki/Image:Climate_Change_Attribution.png

The best summary of the data:

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

The data is why scientists know it's mostly us and not the sun, volcanoes, etc. The data is why the vast majority of scientists think it's real. Proof.

Answer 6

many people forget about desertification
desserts are like a fire they gobble up the edges with the heat and so grow.

the carbon production is something else on top
and this seems to ocupy people the most
and the polution is something else again
all are factors in climate change

Global warming is a very complex collection of many effects

this text 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

climate change is caused for a large part by desertification ,and most desertification is caused by man
the thinner ozone layer helps to speed this up.and this is caused mainly by air polution ,also as a result of mans actions

DEFORESTATION

in the past
the Building of the Spanish Armada deforrested Spain
the Phoenician trading fleet turned Lebanon in a dessert
Ganges Khan put everything to the sword and torch, then filled the wells with sand,
the sun finished of the job and whole countries turned to wastelands.
He would have been envious of the effects of modern day farming.Slash and burn destroys the protective vegetation (which helps to form the soil ),
leaving it open to the Sun ,and then ,wind and, water erosion.
The Plough turns the soil ,killing micro-biotic life (essential to soil building) and accelerates the drying out .
Pressures of the :vehicles, cattle and rain impact brings the salt to the surface.

Mono cultures ,aided by chemicals Exhaust and pollutes the soil .
Adding to this the effects of overgrazing has resulted in large scale desertification.

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 .

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

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
