We know climate change is real, that is why the question is about Anthropogenic climate change.
You can measure pretty much all of the potential influences on global climate, solar activity, weather patterns, glacial melting, volcanic activity, the earth's eccentricity, cloud formations, the wavelength refracted back by the ground and oceans, the amount of infrared radiation absorbed or refracted by the atmosphere etc and after considering them all over time you see a long term trend that is by far more closely correlated with increased global Co2 emissions than anything else, a trend that sees the cycles peak higher and drop lesser than previously, this is precisely why it's a statistically significant effect, as in a 95% probability of their measurements being accurate given the sum of the data.
There are very few climate scientists left that doubt the role of c02 emissions in climate change, those that do have some good arguments but even then the main ones, related to solar activity and cloud formation, have been fairly well refuted - These people are not the ones who kick up the fuss about it either, some of the most prominent climatologists skeptical of anthropogenic climate change are constantly issuing statements because of biased and agenda driven media sources that misuse their studies.
