My conservative friends say it's split 50%, while my liberal friends say it's 100%. I know neither is right, so i was hoping someone could provide me with a link to a survey or something.

Quite frankly, there is no scientific way to be absolutely sure. I believe that humans are driving climate change but there have been huge swings in climate/temperature on earth way before humans were even here. At this point, the best either side can provide is a theory.

I honestly have no idea how many scientists believe that carbon dioxide acts as a greenhouse gas, although I would suspect they certainly aren't split 50/50. However, I have yet to find a single =climate= scientist who doesn't believe that it does (not even Richard Lindzen).
A study performed by Naomi Oreskes of 928 peer reviewed papers dealing with climate found that not a single one did not agree with the IPCC's conclusion.

It's closer to 100%. There are some scientists who dispute the consensus, but most aren't climate experts (geologists, meteoroligists, geographers and the like), and many are funded by the oil industry.
In 2004 an article in Science magazine discussed a study by Prof. Naomi Oreskes in which she surveyed 928 scientific journal articles that matched the search [global climate change] at the ISI Web of Science. Of these, according to Oreskes, 75% agreed with the consensus view (either implicitly or explicitly), 25% took no stand one way or the other, and none rejected the consensus.

caused by greenhouse gases including CO2, 99%
you can find the institution/organization name of every single scientist who disagrees right here:

the skeptic movement is literally funded by ExxonMobil, no other oil company pumps any where near as much money into global warming skeptics as ExxonMobil. Some oil companies have even made statements concurring with the scientific consensus.

Rather than count noses, it's much easier to count research. Madhav L Khandekar has developed a list of 68 peer-reviewed papers that question some aspect of the anthropogenic global warming consensus.
By contrast, the latest IPCC report lists over 4600 references. That would make it about 98.5% in favor of the consensus.

I believe ALL scientists say that increases in CO2 levels do increase the earth's temperature. The disagreement seems to be over which is the biggest contributor to warming is man-made CO2 increases or nature (solar activity, etc.).

99+%. There are a (very) few skeptics. Proof here:
