Do you believe that humans are to blame for climate change?

Well, not exclusively anyway. Human activities are just one of several reasons we are experiencing indications of global warming. Methane gas from the digestive system of cows is a significant addition of greenhouse gasses in the atmosphere. Volcanic activity also adds to greenhouse gasses. Like I said, human activities are only part of the story. There is no blame to place. The largest potential contributor to climate change is volcanic action, which will cool the environment which results from the shading of the ash thrown into the upper atmosphere and huge clouds of volcanic gasses, in particular sulfur-dioxide. Here is a quote:

The eruption plume of Mount Pinatubo's various gases and ash reached high into the atmosphere within two hours of the eruption, attaining an altitude of 34 km (21 miles) high and over 400 km (250 miles) wide. This eruption was the largest disturbance of the stratosphere since the eruption of Krakatau in 1883 (but ten times larger than Mount St. Helens in 1980). The aerosol cloud spread around the earth in two weeks and covered the planet within a year. During 1992 and 1993, the Ozone hole over Antarctica reached an unprecedented size.
The cloud over the earth reduced global temperatures. In 1992 and 1993, the average temperature in the Northern Hemisphere was reduced 0.5 to 0.6°C and the entire planet was cooled 0.4 to 0.5°C. The maximum reduction in global temperature occurred in August 1992 with a reduction of 0.73°C. The eruption is believed to have influenced such events as 1993 floods along the Mississippi river and the drought in the Sahel region of Africa. The United States experienced its third coldest and third wettest summer in 77 years during 1992.

Like I said, mankind is only PART of the problem.
One last tidbit I found somewhere which I think is very interesting:
"The Tsunami of December 25th-26th, 2004 just off the coast of Sumatra, changed the shape of the Earth to make it slightly smaller in diameter, resulting in a shortening of the day by about 3 microseconds in exactly the same manner as a figure skater spinning and pulling in their arms to spin faster. This will result in an additional leap-second each 1100 years. In addition, the wobble caused by the change of shape of the Earth's mass, means we are wobbling an additional 2.5 CM about the axis. And, because of the increased rate of spin, have moved about 2.5 CM closer to the Sun. ALL, as a direct result of this singular event."
THIS little tidbit also means we are receiving more energy per square foot as we are closer to the Sun, which means a fractional increase in the heating effect from the Sun from before to after. Human beings are NOT the only ones to blame here...

humans are not to blame for climate change. The planet has undergone global cooling and global warming 1000's of times in its history without human intervention. The environmentalist organizations don't care about the affect of global warming, all they care about is the money they get from global warming.

The problem you're running into is that you do not know how to do research.
first of all, educate yourself on global warming theory. After you understand what that is, look up:
1) historical effect of co2 on climate
2) percent co2 in the atmosphere now and then
3) carbon cycle
4) how do we effect the carbon cycle, ie,
a. transfer of carbon from under ground to the air and
b. removing trees and reducing natures ability to deal with it
5) methane production from
a. industrial farms
b. land fills
c. waste water treatment plants

No, I do not, and as you stated there is no scientific proof. While of course the gasses we are producing are in fact green house gases, we have not and will not be able to produce enough even at the rate we're going to compete with the planets multiple natural balancing systems and in fact change the temperature of this entire planet. Cause lets face it, we're small and this planet is big, really big. What seems massive to us is in fact but a fizzle to the planet Earth.
Less than thirty years ago the consensus was that the planet was getting colder and would become catastrophic at this rate. They also said that humans were causing it by our gasoline products, claiming that the aerosol being produced by gasoline were blocking the earth from a significant enough amount of solar radiation as well as effecting the natural amount of cloud production. But, than by the 1990s the temperature began to get warmer and the census began to fall apart.
Now you want to know what is fully capable of causing temperature rise and decline? The sun. By all stretch of the imagination the largest contributor to our current temperature and the temperatures we've reached in all human existence and all the temperatures we will reach even. It expands and contracts by very small amounts, it breaths in it's own way and is practically alive in certain respects - it is born, it moves, it feeds off of gasses, it excretes byproducts as well as it's own heat, and in the end it dies. With all that it does, changes in temperature should actually be one of the most comprehensible, yet people want to feel that the sun is static and are able to expect the same exact thing from the sun until it dies. And, while usually the changes made by the sun are, on a solar scale, small, for such a massive object even the tiniest of changes can effect creatures as small as we are.
Whats happening is natural. Nothing but a little change here and there, spices things up. Would get boring if things stayed the same for all eternity.
A good two cents,
