no because throughout earth's history the earth has warmed and cooled by itself. thats why we're not in the ice age anymore

No. The theories behind the issue have been proven wrong.
According to the ice core samples temperature is the driver of co2, not the other way round.
Greenhouse gases warm the earth by delaying the release of the sun's rays back into the atmosphere. According to weather balloons and sattelite data the temperatures in the atmosphere have not warm.
But many people claim it is warm in the city. That is due to the "heat urban island effect". Cities are always warmer (by as much as six degrees) than the surrounding countryside, due to the sun heating up the concrete found in cities.

hey
global warming is happening
Mc is ignorant and misguided.
I attend Sir Sandford Fleming college for enviromental sciences I can assure you that in fact global warming is happening. There are many resonsons Mc is one of the few people who are too blind to notice what is happening. I could go into detail but I would recomand that you watch "an inconvenient truth" it a good moive staring Al Gore he hits at most of the facts or google global warming

Yes. Not because of "logical" arguments or political ones. This is science and data is what's important.
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.

These people are convinced by the science, in spite of their political beliefs.
"The science of global warming is clear. We know enough to act now. We must act now."
James Rogers, CEO of Charlotte-based Duke Energy.
“With overwhelming scientific evidence that global warming is adversely impacting the health of our planet, the time has come for the Congress to take action.”
Senator Olympia Snowe, Republican, Maine
"I agree with you (Gore) that the debate over climate change is over."
Rep. Dennis Hastert, Republican, Illinois
"Global warming is real, now, and it must be addressed."
Lee Scott, CEO, Wal-Mart
“DuPont believes that action is warranted, not further debate."
Charles O. Holliday, Jr., CEO, DuPont
"We simply must do everything we can in our power to slow down global warming before it is too late. The science is clear. The global warming debate is over."
Arnold Schwarzenegger, Republican, Governor, California
"Our nation has both an obligation and self-interest in facing head-on the serious environmental, economic and national security threat posed by global warming."
John McCain, Republican, Senator, Arizona

Well, you kind of have too. It is well known that the earth is heating up. Your real questions should be "Do you believe people are causing global warming?"

I believe it has happened many times in the past but that our lifestyles are aggravating the present natural trend just a little.

Of course. Dont think that anyone in full possession of their mental faculties and (more importantly) not having any vested interests can disbelieve in this.

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. Do not sacrifice your money, time, vote, and conscience to the greedy members of society who are blinding you to the truth for their own greed.
