One of the major things that often goes unmentioned int he news about global warming is that green house gases also serve to create clouds. These clouds actually cool the earth by reflecting the sun away.
Its a bit of a paradox when it comes to global warming because the gases causing the warming also cool things down. It is important to note that this cooling effect is not what will "freeze" the earth. The freezing of the earth has happened before so we know it is indeed possible and when it happened it killed something along the lines of 98% of the life on earth. This type of freezing is caused by the ocean dynamos stopping thus, the energy from the equator can not be transfered to the polls.
SO to answer your question, we do have solid proof of this happening before (obviously not at the hands of humans) but right now we are at a bit of an impass as to what our effect on the earth really is.

I just read today that the Colorado River, the Rio Grande and the Yellow River (in China) quit flowing during summer months. I personally know of quit a few rivers/streams that have either dried up or become intermittant rivers/streams. Lots of reliable sources (not just Al Gore) claim that glaciers, etc., are melting. Cartographers are re-doing global maps because lakes are shrinking; rivers drying up; villages in Alaska are near to becoming inundated.
One other observation in my own life would be Yellowstone Park. From the first time I went there until the last time (3 years ago), the geysers have shrunken, some have quit erupting, the mud pots are smaller.
And, listen to your weatherman; most of the hottest years on record are within the past 10 years.
There is an abundance of evidence for global warming; people just want to ignore it, just like the terrorists, air pollution, inflation and illegals. It is easier to ignore a problem than to try to do something about it.
Remember, people ignored Hitler...

There is consensus among scientists that the earth has warmed since temperature records first started being kept in the late 1800's. This amounts to something like 6/10ths of a degree. Some places have actually gotten colder however. Even within a state like New York some cities have increased their temperature while others have cooled.
The issue is whether mankind is at fault for the warming. My advice is not to choose any answer that sounds like it gives you clear proof of whether man is at fault. Do not listen to the most passionate or loudest voices, nor the most articulate. If you are truly interested read the data from both perspectives. I truly believe both sides believe they are right. There is no malevolent side outright "lying".
Michael Crichton (author of Jurassic Park) has written a fiction adventure book based on environmentalism. In the back there are several scientific references to help you start on your journey. Don't ask me to critique the book, 'cause I think the story line is one of his worst.
Again, stay clear of actors, politicians, and the media. They've all got their own public relations agenda with this topic. Go to the scientists. And definitely stay away from commoners like me and everyone else who responded to this question. God gave you a brain, you're responsible for using it.

The question isn't actually whether or not global climate change (global warming is a misnomer; the theory is that some parts of the world will actually freeze) is a reality. All the major scientists say that the world's climate is indeed changing. The question is to what extent to human beings play a role in this change? That is what everyone is debating on. There has been a lot of research on this, but no one really seems to have a solid answer.
A good movie to watch if you don't want a lot of statistics and boredom is Al Gore's "An Inconvenient Truth". It puts the research in a perspective that almost everyone can easily understand. There's also a book he wrote to go along with it. You can check that out at almost any bookstore.

Hopefully they can stop it...If they can then global warming is still a threat...
Here's a fabulous concept: when you click on this site, Care2 makes a donation that will remove one pound of carbon dioxide emissions from the atmosphere. It doesn't cost you a thing and every click really counts. Check it out:
SIMPLE SOLUTION: Race to Stop Global Warming.
Thought I would leave this just in case anyone wants to help with the problem.

No. This is the same deal as creationism. Scientists have thousands and thousands of independent findings that show the earth to be between 4.5 and 4.6 billion years old. Creationism affirms that it is only 4000 years old, discards all the evidence offered by the scientists, but simultaneously insists they should provide proof. The only proof these characters would accept is if God himself appeared before them and said "You're wrong, now get back to work". God isn't likely to make a special trip just to benefit people like this. The Skeptic/Denier business is the same thing. Both they and the Creationists have been around, but somehow they were declared "credible" when George Bush took office, and the scientists suddenly started hearing that "the jury is still out" on their findings.

The last ice age was said to be an effect of Global Warming. Hasn't anyone noticed a shift in weather patterns around the world and an increase in natural disasters (hurricanes, earthquakes, tsunamis). Its a fact that the world's average temperture is a few degrees warmer than normal, which is not so good since the ice caps are melting as a result.
Its the little things going on around the world that make global warming a harsh reality. My advice, ask an unbiased environmental specialist.

There's lots of proof it's real. Here's just a small piece of it. Much more in the links.
This is science and what counts is the data.
"I wasn’t convinced by a person or any interest group—it was the data that got me. I was utterly convinced of this connection between the burning of fossil fuels and climate change. And I was convinced that if we didn’t do something about this, we would be in deep trouble.”
Vice Admiral Richard H. Truly, USN (Ret.)
Former NASA Administrator, Shuttle Astronaut and the first Commander of the Naval Space Command
Here are two summaries of the mountain of peer reviewed data that convinced Admiral Truly and the vast majority of the scientific community, short and long.

http://www.ipcc.ch/SPM2feb07.pdf
It's (mostly) not the sun:
http://solar-center.stanford.edu/sun-on-earth/FAQ2.html
And the first graph aboves shows that the sun is responsible for about 10% of it. When someone says it's the sun they're saying that thousands of climatologists are stupid and don't look at the solar data. That's ridiculous.
Science is quite good about exposing bad science or hoaxes:
http://www.cs.cmu.edu/~dst/ATG/polywater.html
There's a large number of people who agree that it is real and mostly caused by us, who are not liberals, environmentalists, stupid, or conceivably part of a "conspiracy". Just three examples of many:
"Global warming is real, now, and it must be addressed."
Lee Scott, CEO, Wal-Mart
"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."
Senator John McCain, Republican, Arizona
“DuPont believes that action is warranted, not further debate."
Charles O. Holliday, Jr., CEO, DuPont
There's a lot less controversy about this is the real world than there is on Yahoo answers:
http://www.worldpublicopinion.org/pipa/articles/home_page/329.php?nid=&id=&pnt=329&lb=hmpg1
And vastly less controversy in the scientific community than you might guess from the few skeptics talked about here:
http://en.wikipedia.org/wiki/Scientific_opinion_on_climate_change
http://www.sciencemag.org/cgi/content/full/306/5702/1686 and:
"There's a better scientific consensus on this [climate change] than on any issue I know... Global warming is almost a no-brainer at this point. You really can't find intelligent, quantitative arguments to make it go away."
Dr. Jerry Mahlman, NOAA

it's fake. look at history....
for 40 years, the experts have not had ONE prediction come true!
NOT ONE!
famine
mass death
shifting of food production regions
climate change
overpopulation
global cooling
mass starvation
massive glaciers
uninhabitable places on earth
running out of fossil fuel
all this was supposed to happen by the year 2000, and if man didn't stop using fossil fuels.
now these SAME "experts" want us to "believe" global warming because it's "real"?

Global warming is real, it's happening. Come to Alaska and check out the glaciers. They are melting so fast. If you see before and after pictures of the same area 50 years ago its totally different. But, i think mother nature has a way to supplement that.
