Yes. Forget the political stuff and the "logical" arguments that are posted here. Just look at the numbers and the science.
Yes, there have been natural climate changes before, mostly due to the Sun. But the data clearly shows that, starting about 40 years ago, man's contribution overwhelmed the natural forces that controlled climate before.
This is a nice picture, includes the effect of the Sun, and there are many more scientific studies showing the same thing.

None of the other explanations works nearly as well. The scientific equations don't work for them. The numbers come out wrong. Most questions are answered here:

Hannity and Limbaugh are dumb conservatives. Here's what a smart one says:
"Former Republican House Speaker Newt Gingrich challenged fellow conservatives to stop resisting scientific evidence of global warming"
Good general information on global warming. with data and pictures:

"but NASA and our government web sites all have top scientists that formed a consensus that it is very real"
Science by consensus, that is new. Theories are proved by facts, not consensus.
There was also a global cooling consensus in the 1970's. Then 30 short years later, global warming.
This is also the same government that lies about everything, so how can we believe anything they put on their websites?
Summer was very mild for most of the country until a few days ago, then we finally got hit with it. Two winters ago was one of the coldest on record.
Sure, the earth is getting warmer. So is Mars. So is the sun. Maybe that could be the cause?

Climates change. Sometimes they change fast, sometimes slow. They change. Globally, temperatures are up by about 1 degree on average. If your definition of "warming" is 1 degree, then sure global warming is a fact. I personally think that all the "hot air" coming out of Al Gore is responsible..

Yes. Based on evidence generated by the scientific community (eh, cliches), "Global Warming" is a statistical fact, meaning only that the average temperature on our planet is increasing at a faster rate than anytime in previous history.
And...
No. Previous temperature increase rates are based on theory; how can we compare our current conditions to theories and generate facts?
And...
Yes. Greenhouse gasses create a warming effect by trapping energy from the sun. Humans generate greenhouse gasses.
And...
No. A mass balance on the amount of carbon in and on our planet shows that the number has only slightly increased over the years (from comets, etc). All carbon was at one time in a gaseous phase. That transferred into biomass which ended up as fossil fuels which mankind has become very proficient at extracting and using for energy. However, we've only removed a tiny fraction and will only be able to remove a tiny fraction of Earth's total carbon.
If you believe in evolution, then believe that the earth will take care of herself within the rates that mankind can manipulate her carbon sources to those which cause the earth's temperature to increase because of the greenhouse effect.
Therefore, I would have to say no, Global Warming is not a fact.

Hannity and Limbaugh are part of the axis of evil and as such can't be believed. You must only trust Al Gore. He is going to save the world.

Since 1895, the media has alternated between global cooling and warming scares during four separate and sometimes overlapping time periods. From 1895 until the 1930's the media peddled a coming ice age. From the late 1920's until the 1960's they warned of global warming. From the 1950's until the 1970's they warned us again of a coming ice age. This makes modern global warming the fourth estate's fourth attempt to promote opposing climate change fears during the last 100 years.
The National Academy of Sciences report reaffirmed the existence of the Medieval Warm Period from about 900 AD to 1300 AD and the Little Ice Age from about 1500 to 1850. Both of these periods occurred long before the invention of the SUV or human industrial activity could have possibly impacted the Earth's climate. In fact, scientists believe the Earth was warmer than today during the Medieval Warm Period, when the Vikings grew crops in Greenland.
What the climate alarmists and their advocates in the media have continued to ignore is the fact that the Little Ice Age, which resulted in harsh winters which froze New York Harbor and caused untold deaths, ended about 1850. So trying to prove man-made global warming by comparing the well-known fact that today's temperatures are warmer than during the Little Ice Age is akin to comparing summer to winter to show a catastrophic temperature trend.
Something that the media almost never addresses are the holes in the theory that C02 has been the driving force in global warming. Alarmists fail to adequately explain why temperatures began warming at the end of the Little Ice Age in about 1850, long before man-made CO2 emissions could have impacted the climate. Then about 1940, just as man-made CO2 emissions rose sharply, the temperatures began a decline that lasted until the 1970's, prompting the media and many scientists to fear a coming ice age.
A letter sent to the Canadian Prime Minister on April 6, 2006 by 60 prominent scientists who question the basis for climate alarmism, clearly explains the current state of scientific knowledge on global warming. The 60 scientists wrote: "If, back in the mid-1990s, we knew what we know today about climate, Kyoto would almost certainly not exist, because we would have concluded it was not necessary." The letter also noted: "‘Climate change is real' is a meaningless phrase used repeatedly by activists to convince the public that a climate catastrophe is looming and humanity is the cause. Neither of these fears is justified. Global climate changes occur all the time due to natural causes and the human impact still remains impossible to distinguish from this natural ‘noise."
In 2006, the director of the International Arctic Research Center in Fairbanks Alaska, testified to Congress that highly publicized climate models showing a disappearing Arctic were nothing more than "science fiction."
"Geologists Think the World May be Frozen Up Again." That sentence appeared over 100 years ago in the February 24, 1895 edition of the New York Times.
A front page article in the October 7, 1912 New York Times, just a few months after the Titanic struck an iceberg and sank, declared that a prominent professor "Warns Us of an Encroaching Ice Age." The very same day in 1912, the Los Angeles Times ran an article warning that the "Human race will have to fight for its existence against cold." An August 10, 1923 Washington Post article declared: "Ice Age Coming Here."
By the 1930's, the media took a break from reporting on the coming ice age and instead switched gears to promoting global warming: "America in Longest Warm Spell Since 1776; Temperature Line Records a 25-year Rise" stated an article in the New York Times on March 27, 1933.
The media of yesteryear was also not above injecting large amounts of fear and alarmism into their climate articles. An August 9, 1923 front page article in the Chicago Tribune declared: "Scientist Says Arctic Ice Will Wipe Out Canada." The article quoted a Yale University professor who predicted that large parts of Europe and Asia would be "wiped out" and Switzerland would be "entirely obliterated."
A December 29, 1974 New York Times article on global cooling reported that climatologists believed "the facts of the present climate change are such that the most optimistic experts would assign near certainty to major crop failure in a decade." The article also warned that unless government officials reacted to the coming catastrophe, "mass deaths by starvation and probably in anarchy and violence" would result. In 1975, the New York Times reported that "A major cooling [was] widely considered to be inevitable."
On February 19, 2006, CBS News's "60 Minutes" produced a segment on the North Pole. The segment was a completely one-sided report, alleging rapid and unprecedented melting at the polar cap. It even featured correspondent Scott Pelley claiming that the ice in Greenland was melting so fast, that he barely got off an ice-berg before it collapsed into the water. "60 Minutes" failed to inform its viewers that a 2005 study by a scientist named Ola Johannessen and his colleagues showing that the interior of Greenland is gaining ice and mass and that according to scientists, the Arctic was warmer in the 1930's than today.
According to data released on July 14, 2006 from the National Oceanic and Atmospheric Administration (NOAA), the January through June Alaska statewide average temperature was "0.55F (0.30C) cooler than the 1971-2000 average."
In August 2006, Khabibullo Abdusamatov, a scientist who heads the space research sector for the Russian Academy of Sciences, predicted long-term global cooling may be on the horizon due to a projected decrease in the sun's output.

Global warming is a fact. Human caused global warming is a wishful thinking on the part of the left. I always find it enlightening that they chose not to distinguish the two.
