We have no information about the last major climate change in prehistoric history--we have no data.
That being said, have humanity made a significant increase in the speed of the climate change? YES!
BUT I do not believe that humanity cause it all. I believe that it was just increased. Everything comes and goes in a cycle; who are we to say this isn't one of them? We just don't know.

It is hard to prove that they (we) are NOT responsible, but it is equally hard to prove they are.
The earth has constantly warmed and cooled through time. Volcanoes formed the land masses, rain cooled them, ice ages occurred, etc.. and there were no men to influence this development. The "record" temperatures that we are discussing are a blip in time, as we have only been recording since the 1880's and only with reliable and consistent equipment for 50-60 years.
Yes, we contribute to the greenhouse gases, but so do cows, sea animals, volcanoes, and so on. The science that is so often pointed to such as the hockey-stick theory in Al Gore's movie is long proven scientifically false. The unfortunate case now is that those that do not agree with the Global Warming theories are not allowed to voice their opinion. The media, Hollywood and those that benefit from pushing that agenda have the power. Only time and additional study will determine the correct-ness of any current theory.

humans arent responsible for global warming because in the past years we have seen plenty of examples. a long time ago i think it was just before the ice age they said that the earth was heated up to a very high temperature. then a long time after that it happened again. but the facts almost certainly prove to some people that humans have nothing to do with global warming.

They are.
The Carbon Dioxide, Above the normal amount is what
causes Global Warming. Cars take in Oxygen and Spew
out unimaginable amounts of CO2.
Trees are being "Slash Cut " in our Forests. Trees
maintain a Chemical Balance in our Atmosphere.
Trees Absorb CO2, and emit Oxygen. People Absorb
Oxygen and emit CO2. This Cooperation Makes for an
Atmosphere that allows mankind to survive.
The Forests are also being burned by natural means and
by Men. This disrupts The chemical balance in our
Atmosphere.
Internal Combustion Engines take in Oxygen and spew out
enormous amounts of CO2. This is a double Whammy to our Atmosphere.
Man is destroying our Atmosphere and it will show up in
the major medical problems that people will soon notice
that are due to the rise in Global Warming.

What intoxicating vanity people have, especially Environmentalists.
HUMANS DO NOT HAVE THE POWER TO ALTER OUR ENVIRONMENT... EVEN IF WE WANTED TOO !!!
We could, if we wished, make this planet uninhabitable for US !!!... maybe... It would be tough, real tough... but It MIGHT be done with a lot of effort... but destroying the Earth or destroying all life on this planet... impossible... especially with our limited technology. You must remember, human beings are a fairly new species to this planet, having been here for perhaps 100,000 years... perhaps a little less... and I have a feeling that humans will be long gone off this realm before anything happens to planet Earth. Eventually, in the distant future, when Mother Nature has had enough of these self important, arrogant twits called humanity... she'll shake us off of her Terra Firma like a bad case of fleas and think nothing of it afterwords.
Tax the poor !!!

Between the fourties and the seventies, carbon emmisions increaced every year. But, the climate got cooler. There was even a newsweek article written warning that we may enter another ice age!
Further more, how would the Earth have ever gotten out of the ice ages without the earth warming and cooling on it's own.

The final answer to this question is not yet in. And although I lean towards accepting the human contribution to global warming and our consequent need to help curb it, I still hear and see evidences to the contrary. Yesterday on C-SPAN radio the House Oversight and Government Reform Committee (led by Chairman Henry Waxman, U.S. Representative, D-CA) interviewed James E. Hansen, Director, NASA, Goddard Institute for Space Studies who has been the most outspoken climate modeler and protagonist for global warming due to CO2. Also interviewed were Roy Spencer, Principal Research Scientist, University of Alabama in Huntsville, Earth System Science Center,
James Connaughton, Chair, White House Council on Environmental Quality, Philip Cooney, Chief of Staff (Fmr.), White House Council on Environmental Quality,
and George Deutsch, Public Affairs Officer (Fmr.), NASA.
This House Oversight Committee was conducting this hearing on possible political interference in the work of government climate change scientists. However most of the discussion seemed to be on global warming per se. And listening to this Committee you definitely understand why there is still controversy and lack of a general consensus on the subject.
One of the reasons some scientists have offered in place of CO2 greenhouse gas (and which was not discussed in yesterday's hearing) as the major contributor to global warming is the extremely high correlation between sun-spot duration and the planet's temperature increase. Let me cite the following as evidence is support of this theory:
http://www.tcsdaily.com/article.aspx?id=010405M
The bottom line for me, a scientist is this. Do what I can to curb the use of fossil fuels and continue to gather information on all sides of this issue. Remain open and do not jump on any one side of this issue too quickly. I'm personally sorry for having appeared to have committed this mistake in some of my own contributions in this venue and I urge all of you not to do the same.

Humans are not responsible for global warming because in order to survive, we must do things that CAN cause harm to the environment; however, without these things (such as heaters so we don't freeze to death) humans would cease to exist.

We are responsible, but it could be another ice age that causes the same things as global warming does ie- different weather patterns

Hey Zordax, Humans not configured for global warming sensitivity mode, I think lets get tidal wave hit them. Standing by for orders. Blukleg signing off.
