Can anyone who doubts the humans are causing the current changes in Earths climate offer any real evidence to support their claims? Making speculations about specific data sets is not evidence, please site current studies that have been peer reviewed by the scientific community.

There is much direct evidence. An example is the current CO2 levels are higher now than in the past 650,000 years.

Actually I should have included that CO2 levels have been constant for at least the past 10,000 years and have only been increasing at the current rate for the past 150 years or so. Additionally the current increase has not been seen on this planet for at least 650,000 years

I am not a climatologist, and I have no data or journal citations. My take is this: fossil fuels are what? Organic matter that has decomposed and very slowly turned into coal, oil, pockets of gas, etc. So eons of the sun's energy is held in the chemistry of these organic molecules. And what do we do? We extract it and release that energy in a mere blip of time that it took for that energy to accumulate. How can that not have an effect? We are releasing energy at a rate much greater than it was created, and at a rate greater than the system (atmosphere) can absorb. Without a doubt, there will be an impact. I would think that even with a pre-settlement amount of vegetation the ability to absorb CO2 would be insufficient at the rate we're releasing it.
Just my take, and I'd be interested to hear why I'm off-base.

You state: "There is much direct evidence. An example is the current CO2 levels are higher now than in the past 650,000 years."
Everyone agrees. The question you asked is: Did humans cause this? Or more specifically: Prove humans did not cause this.
My argument is this: Your statement indicates that CO2 levels have been rising for 650,000 years (which you provide no proof of, but ok). Humans have only been producing greenhouse gases for, what, 150 years? So what explains the other 649,850 years of CO2 increases? Certainly not human industry.
There you go: PROOF that greenhouse warming is not due to human activities.

There is a study going on in Australia that is blaming Cow flatulence for global warming. People are saying that the global warming in the past was caused by dinosaur flatulence. I don't believe it either but I just want to point out that a lot of crack pots are blaming a lot of things for global warming. everyone has a theory but no one has real proof.
The greatest contributor to CO2 in the atmosphere is tundra in Alaska and Canad which is a plant that takes in Oxygen and gives off CO2.

Everyone talks about the disasterous effects of global warming. But geologically speaking, we are in a rare period of global cooling. The history of the earth only rarely has ice, even at the polar regions. Life has continued to exist despite changes in temperature, and there is no reason to think that life will die off due to global warming. Human life might not survive, but then we might be a casuality of our own devices. Would that be bad?

Ever gone to a confrence room that was comfortable when the first people arrived,were the room over-crowded did the temperature get warm! If no one opened door or adjusted the thermostat did it remain or gain heat? our planet has a pressure wall surounding it ,the planet is gaining in bodies(human and animal) on more surface than any time in world history;add bombs exploding and forest-fires,and fuel burning in accidents. Yes the planet is warming some,so what do you propose to do about it? Stop wars, genocide of unfriendly nations, or electric powered vehicles in every nation of Earth?lol

History shows us that humans do not have a disasterous effect on climate. That and the fact that global warming scientists cannot prove global warming either, since they can only really compare meteorological data from the past 60-70 years or so, anything beyond that is a guess. The global warming believers I like to compare to the medieval "The World Is Flat" crowd (Not Tom Friedman).

Oh certain, Perry is a genius and he will shoot you including his six shooter in case you dare disagree. At one time he and Al Gore became brilliant friends yet that became even as Perry became a Liberal. Karl Rove promised Perry that if he crossed over he would make him a senator and if he performed ball, per chance even president. even with the undeniable fact that, once Perry were given to be senator he went rogue and not one of the republicans like him because he wan't a crew participant. Karl's new boy became Bush and Bush became a crew participant.

Can you show me case studies and scientific evidence that these shifts in the Earth's climate didn't have the same pattern 1,000, 10,000, 100,000 years ago? Yeah me either.

You do the same, providing documentation on the persons making the claims that they are fully qualified to conduct and evaluate such a study without bias!
