When discussing this issue there are three questions:
1) Is the rising temperatures due to human behaviour or part of a natural cycle.
2) How much will co2 cause temperatures to change.
3) What will be the consequences of those changes.
One of the major assumptions is that increases in co2 cause an increase in temperatures. The evidence from the ice core samples from Antarctica shows the opposite. So CO2 is a follower and not a leader. I have read hypothesis as to why this occurs but no study. This also affects the computer models for predicting temperatures.
As for the consequences there are different reports. Sea levels are not rising to threatening levels world wide. In some places they rise in other places they have fallen. For the theory to be true they should rise world wide. http://www.canada.com/nationalpost/financialpost/story.html?id=d0235a70-33f1-45b3-803b-829b1b3542ef&k=99551&p=1
Personally, I am very suspicious of people who try to enforce censorship. You hear climatologists say that funding for global warming gets pulled if they do not tow the global warming theory. One of them has even received death threats. Most of them are harassed. So what you are seeing is a debate were one side is loaded with money and the other side is not. Do you consider that fair and scientific?
And how do they debunk their critics? All of the top scientists support global warming you should to. Studies that are against them can not be trusted because they are supported by the oil industry, without really saying what is wrong with the studies. But at the same time they want us to trust them that their studies are unbiased, even though if proven false they would be out of a job.

There's two types of global warming - natural and man-made.
Nobody disputes that natural global warming is occuring and has been for the last 18,000 years. It was this that brought about the end of the last ice age. Throughout the history of the planet there have been periods of warming and cooling and there have been several ice ages.
The issue that's causing so much concern at the moment relates to just how much and how fast temperatures have been rising since the Industrial Revolution some 200 years ago.
Over the last 18,000 years the world has warmed up by an average of 0.0005 degrees Celsius a year but in the last 25 years the rate of increase has been 0.0156 degrees a year - 31 times as fast as would be expected.
Global warming has huge implications for all of us in the way we live our lives. The costs involved are staggering and the effect on businesses (especially oil companies and the like) will be damaging. Not surprising then that some governments, big businesses and oil comapnies actively disputed global warming.
However, things have now changed - every government in the world acknowledges global warming so too does every major oil company and the CEO's of the world's 1000 largest organisations unilaterally declared that climate change was the biggest issue facing humanity.
In the past there had been a deliberate policy of misonformation, distortion and attempts to discredit the science of global warming. Members of the Bush Administration were instructed to rewrite scientific reports and to produce their own data to substantiate their claims that global warming wasn't manmade. This wasn't unique to the Bush Administration, many other governments and large oil companies have admitted doing likewise.
The result of this is that there is a lot of 'propoganda' doing the rounds which leads to much confusion. Doubtless you've heard many arguments that are put forward as proof that global warming isn't happening - after 23 years of investigating them I've yet to find one that is credible.
In short, global warming is true. It's irrefutable that the world is naturally warming and it's almost certain that human activities have contributed to the unprecedented rise in recent years.
There's more information on a website I've put together, this page directly addresses the question you posed http://profend.com/global-warming/pages/establish.html , you'll find citations to all the above statements on the website.

A Global Warning on Global Warming
The top of the world is melting. There's been a debate burning for years about the causes of global warming, but the scientists you're about to meet say the debate is over. The seas are rising, the earth is getting hotter and polar bears may be headed toward extinction. What does the melting Arctic look like? 60 Minutes Correspondent Scott Pelley went north to see.

Yes, global warming is true, though the people who don't want to look at the problem (it's very depressing after all) will tell you it's just scare-mongering, but it isn't. I have noticed it in my own garden; plants that usually die over winter are just going on and on flowering through the winter and continue all the time until they look so scruffy that we pull them out. These are normally what is called annuals. This year we have just found cherry trees starting to flower and it's autumn here (Australia) They usually just flower in the spring. It's too early to tell yet but it may be that they will have short lives because they're having to put extra effort into flowering continuously.
I've also seen plenty of evidence of the melting polar ice-caps.We have a friend who works in research who told us years ago what was happening, but said the politicians wouldn't do anything about it because it was a hot potato and it would involve a lot of unpopular remedies that would cost the country plenty of money, and mean that we couldn't just go on making money out of the earth, we would need to look after it if we were to survive and leave a world for future generations. Politicians are such cowards, the want to stay in POWER at all costs. Even if it costs us the Earth. We all need to get informed and make the pollies do the right thing! (Or throw them out and get some who will)

Yes.
Here's proof that the vast majority of scientists think it's true:
http://www.sciencemag.org/cgi/content/full/306/5702/1686
Here are details on a website run by a group of climate scientists:
http://www.realclimate.org/
There's a huge body of verified scientific data saying that it's true. Here's the best summary of that data:
http://www.ipcc.ch/SPM2feb07.pdf
There are some people who deny it for various reasons. But science is against them. They put out misleading stuff like the swindle movie;
" A Channel 4 documentary claimed that climate change was a conspiratorial lie. But an analysis of the evidence it used shows the film was riddled with distortions and errors."
http://news.independent.co.uk/environment/climate_change/article2355956.ece
Here are scientific refutations of their arguments:
http://info-pollution.com/warming.htm#WEB
Here's the bottom line:
"the question of global warming was settled years ago for all but a few holdouts in the scientific community"

Sure it's true. What do you think melted the last ice age? And the one before that? The climate is always changing. Global warming is real enough. The question is how much of it is caused by humans. I believe that humans have very little, if any, effect on the climate.

particular it particularly is, in basic terms seem on the strange climate! The ice caps are in undertaking and polar bears are loss of life. and however if the scientist are incorrect, which I extraordinarily doubt, then why might it harm to assist keep the planet by way of using possibilities, and not being so grasping. Greed is killing the worldwide, because of the fact people in basic terms choose to do issues the cheap undemanding way, like putting weed killer on issues instead of pulling them, or procuring inorganic issues instead of organic and organic ones. I understand you may not constantly have the money for it, yet you may a minimum of be to blame while using undesirable options. you're stupid and don't choose to admit you play aside in hurting the worldwide. it is likewise reason by way of overpopulation. in basic terms admit and use greener issues.
