I'm sorry, but I don't consider a single video to be the end-all of scientific fact. I have experience with understanding issues, and it NEVER comes from a single source. I have seen quite enough about climate change to know that there is a possibility that it is natural and that it may be unnatural.
There may be scientific fact, studies, research, the whole she-bang. However, there is no way to tell what may be skewed, omitted, exaggerated, etc. Even if it was a total synopsis of everything science has found, science itself can often be distorted or controversial -- it's possibility, not truth.
More sources need to be weighed, compared/contrasted, and analyzed. There is not a clear consensus yet.
