What do you mean by facts? Both sides have their "facts" it depends on what side of the issue you are on. If you believe in models that can't recreate past weather conditions as accurate and wrong assumptions "proven" to be correct by faulty science you will believe that climate change is definitely man made. If you believe in historical records, actual facts of the make up of green house gases and other more hard facts that are ignored then you see that man's contribution is only around 3% and there is no substantial proof that man is driving the climate off an edge that it hasn't been ever.
