Believe what you like. I know you will, no matter what I tell you. And this is one of the basic problems of the state of the world today.
I blame Martin Luther. Not Martin Luther King, who worked tirelessly and non-violently against racism in the US, Martin Luther, the German monk who in 1517 detailed 95 ways in which the Catholic church was corrupt. In fact, I think we can lay the whole climate change problem, not just the problem of recognizing its existence, at his feet.

I'm getting a little bit of this history from Wikipedia (
http://en.wikipedia.org/wiki/Martin_Luther) which also reflects another aspect of the whole conundrum.
And what is the problem? Well, we believe what we want to believe because we have lost a sense of trust in authority. Back in the 70s, my friends and I used to sport buttons stating "question authority." Now I want one that says "Stop questioning authority!"
Some people discount the credibility of Wikipedia because it is edited by volunteers. Anyone can add information, or change information. We need an authority, like Encyclopedia Britannica, say these folks. But studies show, if you believe such studies, that Wikipedia is at least as reliable as E.B. and when it has errors, it can be quickly changed.
So Martin Luther said "Don't trust priests. Find out for yourself from the Bible." (Obviously these were not his exact words; he probably wrote in Latin, and more formally.) This change in thinking also led to people questioning everything, and eventually led us to the scientific method, the industrial revolution, the invention of the automobile, carbon in the atmosphere, and climate change. And the change in thinking led people to believe Bjorn Lomborg or David Suzuki, Mitt Romney or Barak Obama, and even Sarah Palin (in some crazy circumstances.)
I really believe in finding out for yourself. But I don't have the time or scientific knowledge to read the scientific studies and discern which are most credible. I can't wade through the statistical evaluations. I can't take polar ice cores. I can't measure the temperature around the globe. I have to go to someone else and get some information.
The really great place to get a sense of what the state of the debate is right now is in the comments section of articles about climate change. Many writers cite statistics and studies. You can read these and feel justified in your belief that the world is getting hotter, not hotter, hotter but not due to humans. Do you want to believe that it's all the sun's fault? Read this:

I don't have the ability to wade through it. But to summarize (and I got this from one of the early paragraphs), it says the opposite of what the IPCC says. Go ahead and buy a Hummer; climate is driven by the sun.
My sense is that when you read an article that is skeptical about climate science, then the comments will be mostly filled by people who are also skeptical about climate science. If you read an article document some new way that we see the climate changing, then the comments will be mostly filled by people who believe the same. Where it gets interesting is when you read mainstream press articles. One of my local papers,
the Province, and especially its chief idiot columnist Jon Ferry, seems to delight in keeping the idea alive that climate change is a hoax. My guess is that 90% of the comments to his articles exhorting us to buy more cars, build more suburbs, and generally use the planetary resources like they are so many McDonald's hamburgers are in agreement. British tabloids are worse.
There was a time in my life when I was young and naive, and I thought that people were rational and swayed by logical arguments. No longer. Most people have some vague notion that climate change is one more problem out there that they can do little about and don't really need to pay attention to the details of. Those who do care are mostly talking to one another, not trying to think about whether they should be changing their minds at all. I intend to post later about why I think this is an important consideration when we talk about the state of the world. In any case, we believe what we want to believe.
The bottom line about climate change is that we shall see. If you believe the above cited article, then keep your woolies because by 2020 things should be cooling down. If you believe, as I do, the scientific consensus, then by 2020 things should be definitely warmer. If I make it to a ripe old age, they may have a hard time digging me a grave in the frozen ground. Time will tell. Believe what you like.
But if the climate models on atmospheric gasses are correct, by then it will be too late to change.
